Simple CAPTCHA – My 1st Plugin for WordPress

It’s study week and guess what? I code my 1st plugin for WordPress since I want a simple yet secure CAPTCHA system for my comment area to prevent spam.

Those interested can download the plugin from here. Currently it’s version 1.0 (beta). For demo, you can try post comment. But please dun ever spam….

You may give comment on the plugin and report bugs by commenting this post.

Go to download page

Update:
For those that installed the plugin and can’t see the CAPTCHA, please logout and check again. Admin do not need to go through CAPTCHA challenge.

If you encounter problem such as unable to view the captcha image after you’ve activated the plugin, please check the directory to the plugin files. It should be ‘plugins/simpleCAPTCHA/’.

very well thanx


60311 @ Jan 26 2008 06:19:04 PM

Very nice plugin, thx!


Zed @ Feb 01 2008 08:52:35 PM

Thanks a lot for good and simple plugin )
There was only one problem with paths in images URL.
I replaced a relative path (./wp-content) by absolute path (/wp-content).


Frederiek @ Feb 02 2008 01:56:34 AM

hi there,

I like the idea of your plugin cause a blog with a nice pagerank has to block a lot of spamcomments with Akismet…

But i don’t seem to get the plugin working on our blog : http://blog.sevenedge.be

any reasons why i don’t seem to get it working?

my permalink structure is Date and name based, maybe that’s the reason why i don’t seen the image with the security code in? i only see “security code” and a field to type characters in, but no image of security code nor the refreshbutton for the code

thnx for your help

Frederiek


zorex @ Feb 02 2008 06:11:42 PM

Get the latest version, it contain some bug fix and can work on date and name permalink


gestroud @ Feb 03 2008 09:09:31 AM

The captcha images aren’t appearing on my site because of the folder name change. :-( The image source is simple_captcha.


zorex @ Feb 03 2008 03:56:38 PM

Sry for that part, i forget to update the SVN server with the folder. Now Its updated and it should work as it would be. Please remember to COPY the folder name “simple_captcha” inside the folder after extracting the zip archive.


jhoech @ Mar 21 2008 03:02:23 AM

Very nice plugin. Works right from the start.


shef @ Apr 02 2008 05:55:46 AM

Hi!

Thanks for nice plugin!
Maybe you should write about dependencies: php-gd


Dino @ Apr 03 2008 10:42:53 PM

Hi, I noticed that your plugin fails to autopopulate multiple-line comments, if user provides an incorrect code. Reason is that \n and \r get passed through from PHP to javascript. As a quick fix, I simply did str_replace( “\n” .. and str_replace( “\r” .. and sandwiched the javascript autopopulation with try { } catch( e) { } clauses. Hope this helps someone. Good work so far.


Justin @ Apr 20 2008 10:43:17 PM

I still don\’t understand what you mean by \"copy\" the folder – I\’m not used to that sort of thing.


zorex @ Apr 21 2008 02:36:38 AM

Its simple, after extracting the file, copy the directory name ’simple_captcha’ to your plugin directory.


Josh @ Apr 26 2008 07:29:52 AM

I had a problem with the image not showing up then I saw most other captcha plugins require GD php (not listed as a requiremetn for yours), once I installed that in linux it works.


Einchi @ May 05 2008 12:26:29 AM

Is it require GD library?


zorex @ May 05 2008 07:58:10 PM

yea, it require GD library. will list it as a requirement on next release.


Steve @ May 24 2008 07:55:33 PM

Fantastic plugin and so simple to install. Thank you very much :)


Fritz @ Jun 04 2008 10:26:11 PM

The image doesn\’t show. I pursued installing GD lib but eventually discoverd that it\’s already installed. PHPINFO shows a GD section indicating \"GD Support enabled\". I have Simple CAPTCHA deactivated at the moment. HELP.


güvenlik kamerası @ Jun 18 2008 04:14:15 PM

Hello, For me also security most importand thing. Because i am livin in middle east and here have many terror. More over every day can dies some body. And we are using the here many security protection and metarial.


david @ Jul 07 2008 10:39:16 AM

easiest and terrific tool… one quick question: how do you change the color scheme? I have blue numbers on blue background and it\’s just impossible to read.

Cheers
Dave


zorex @ Jul 07 2008 03:43:02 PM

Yes, you can change the background image. Just go to the plugin folder where the simple captcha images reside, replace the one you wish to change with the same image type and resolution.


TheHave @ Jul 15 2008 03:05:39 PM

I have some problem with Frederiek…

i tried on localhost, it`s work with date and name based and others permalink…

but when it`s upload to my server the images is not shown.

Any idea ??

Thanks…


zorex @ Jul 16 2008 11:13:41 PM

have you check the path to the plugin and make sure its readable? You might need to CHMOD the plugin folders to 0755


guyinwonder @ Jul 24 2008 11:00:23 AM

Dear Zorex,
I Currently installed Simple Captcha but he image did not shown, i’ve check there is gd library installed. what should I check next so I could show the immage ? currently disable the plugin.


zorex @ Jul 24 2008 03:12:31 PM

pleaase check if the path to the files is ‘/wp-content/plugins/simple_captcha’ and make sure it’s readable (CHMOD 0755)

You need to logout as admin to view the CAPTCHA cause admin do not need the CAPTCHA test to post comments.


ari4u @ Aug 04 2008 06:37:11 AM

I have two servers. One with WP2.5 and other with WP2.6.
This plugin works on WP2.5. The security code does not show up in 2.6, only the edit box does. Both servers are exactly the same configuration from the same provider.

I followed your instructions… Is there something i am missing?


zorex @ Aug 04 2008 07:02:41 AM

Please provide me a link to your blog, I can help you check


Locus @ Aug 13 2008 09:54:05 PM

Hi all, I guess I’ve found a bug concerning the image url (as guyinwonder wrote). I have Wordpress 2.3.1 installed.

In the source of your plugin, in the file zrx_captcha.inc.php,
you call the following function several times:
bloginfo(’url’)

But, in case the blog admin gave Wordpress its own directory (as I did ) – codex.wordpress.org/Giving_WordPress_Its_Own_Directory, url of the site differs from real wordpress url and both images( code and reload button) have invalid url.

So you should instead call
bloginfo(’wpurl’)

I rewrite is this way and it works now.

Anyway, nice plugin.
Regards,
Locus.


ari4u @ Aug 17 2008 05:16:34 PM

Sorry, did not check back for replies in a while. I had found the problem after i posted. The plugin assumes the index.php is in the same folder as the rest of wordpress files. In my case, i have my blog files inside a sub-folder on the root and the index.php is on the root.

E.g. http://www.site.com will show my blog as index.php is on the root… but on my server i have placed rest of wordpress files in http://www.site.com/blog. I fixed the path in the plugin and everything was okay.

thanks for your help and for the helpful plugin.


ghprod @ Sep 23 2008 06:19:32 AM

Hi …
Thnx for ur work :)


Cathy Edwards @ Nov 26 2008 05:59:38 AM

I downloaded this plugin today and when I tried to install it I received a fatal error. It related to the zrx_captcha.inc file (line 22). After reading the above feedback, I took Locus’ suggestion and changed bloginfo(’url’) to bloginfo(’wpurl’). Once I did this, it installed correctly.

Thanks for a great plugin.


kurye @ Nov 28 2008 08:09:16 PM

Your site looks cool,really informative…


Subba Rao @ Dec 30 2008 03:08:59 AM

Thank you for this plugin! I am using at my site now. The amount of spam messages were increasing daily. Hopefully your plugin will stop that.

FYI, I use Firefox and IE on Vista. Firefox places the “Simple CAPTCHA” in the middle of the page. In IE, it works great.

Thank you once for this plugin!

Happy New Year!


Oshana @ Jan 17 2009 08:01:02 PM

Would love to use your plugin but …

“Simple CAPTCHA” activated in blog.oshana.org but captcha image is not showing in various browsers. Firewall logs show do blocks. what could be the cause and solution?

John Barrett @ Mar 06 2009 03:22:55 PM

How do I get this working?
I downloaded, upload to my plugin folder, active, but nothing????

Please help


zorex @ Mar 06 2009 07:47:24 PM

Actually its working. You cant see it simply because you are login as admin. Admin do not need to go through the CAPTCHA test. ;D


fun forum and site @ Mar 13 2009 12:20:07 PM

Hi, can we make it work for those logged in as well? also, can i use it on the 2.7 version of WP? Thanks, it is beautiful! :)

Can you help? Advise?

Alanna @ Apr 04 2009 07:56:25 PM

I recently came across your blog and have been reading along. I thought I would leave my first comment. I don’t know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.

About Identity Theft and stolen passwords, recently I came across a site that uses Biometrics of finger, face and voice verification so the user just scans to log on. You can read more at http://www.mybiodentity.com


zorex @ Apr 05 2009 01:56:55 PM

@Alanna: Thnx for leaving a comment. And thnx for your support as well. Hopefully my future post will interest you as well. ;D

@biometric: Thnx for sharing, the site is very informative. Too bad not everyone have fingerprint scanner (like me ;p).


o.me @ Apr 14 2009 08:45:34 PM

lol fixed it^^ after the update you plugin created a subfolder and the files were moved to the wrong place…or was it me? Dunno.

Thx anyway for this fantastic plugin!


KB @ Apr 24 2009 08:32:00 PM

Installed, but couldn’t see plug-in listed in my plug-in directory. Via FTP could see that the folder was created etc.
The check did appear below comments, but couldn’t get the actual security code images to appear. Any thoughts?


zorex @ Apr 25 2009 12:20:24 AM

This is usually because the path to the image is invalid. The path to the plugin should be “/plugins/simpleCAPTCHA/” not “plugins/simple-captcha/simpleCAPTCHA”


Online yildizname @ Apr 30 2009 10:41:14 PM

thanks you very mach


gridman @ May 05 2009 12:37:30 PM

I’m a software developer in the Windows world, so I’m a little lost here. I have the plugin at “wp-content/plugins/simpleCAPTCHA” and permissions are set. But I get an error in zrx_captcha.inc.php on line 22:

frm.src = “/wp-content/plugins/simpleCAPTCHA/gdimg.php?re=” + count;

Since I’m lost in php, can you tell me if I should put my full url in place of the partial url listed above? WP is installed at the root of my domain, so no substituting ‘url’ with ‘wpurl’.

When I put the full url in on this line and the others that need it, I still get the error.

Thanks for your help.


zorex @ May 05 2009 08:20:25 PM

Mind showing me the exact error you get? Is it a php error in the script or javascript error? There shouldn’t be any error if you don’t modify anything in the original source


gridman @ May 05 2009 10:48:11 PM

Thanks for replying. I did not modify your code at all.

Actually it is solved now. I did not do a proper installation. I had the original copy of the plugin which was installed by WordPress. It was at wp-content/plugins/simple-captcha. I also had the copy that I moved to wp-content/plugins/simpleCAPTCHA. Having two copies at once was the problem. I deleted the old copy and activated it just fine.

Thanks again.


Christopher Luft @ May 06 2009 03:55:53 AM

I was hoping you might be able to help me… maybe you have dealt with this issue before. I have tried to install simple captcha by uploading the folder to my plugins directory and was not able to see it in my plugins GUI to activate, so I deleted the folder and tried to use the automated wordpress installer and it also never showed up in my plugins directory. I am using version 2.7.1. Now, even though I can’t see it, there are broken image links and a field asking me for the security code… I tried putting the simpleCaptcha folder back into plugins but they do not link the images to the page (((sighs))). I was wondering if on install your plugin inserts codes into any other files, or if you know a way that I cna manually remove all bits from it. I would jsut like to go back to a straight comment form or try a fresh install. Thank you very much for taking the time.

Best regards,

C.Luft


zorex @ May 06 2009 04:47:13 AM

Reply sent to your email. That should be the common problem faced by a lot of people.


matt @ May 06 2009 10:20:39 PM

Web plug in is not working on this BLOG site…
http://crmweblog.crmmastery.com/2009/05/1593/

Can you look into it…


zorex @ May 07 2009 04:30:05 AM

Check the entry on top. I’ve added new guide to those facing this problem.


George Perry @ May 08 2009 03:37:41 AM

I installed the plugin through Dreamweaver and through the Wordpress automated install when I try to activate it, it simply disappears from my installed list in the Wordpress GUI, but in my comments section on the site it asks for a security code without providing one. Really need to get this fixed. Thanks.


zorex @ May 08 2009 04:09:50 AM

reply sent to your email. For those having problem of cant see CAPTCHA img after activating, please read the updated guide above.

Fatal error: Cannot redeclare class zrx_captcha in /home/island/domains/islandchina.com/public_html/blog/wp-content/plugins/simpleCAPTCHA/zrx_captcha.inc.php on line 22

When I tried to activate this simple Capcha plugin in my new blog, the above error message appears.

How can I fix this fatal error? I have root access to my server and can change file attributes of any folder or file.


moralde @ Jun 05 2009 11:06:32 AM

This particular captcha prevents robot spammers and people with poor eyesight from commenting.


Brian @ Jun 11 2009 12:19:13 AM

After a bit of trouble i final got this working and it was so simple. When you upload it from wp plugins add new, it puts it in a folder /plugins/simple-captcha/SimpleCaptcha you need to remove it from the simple-captcha folder so it is in plugins/simpleCAPTCH folders only. The simple-captcha folder seems to be the problem, well it was for me anyway.

Great plugin btw :)

Brian


London escorts @ Jun 19 2009 09:10:50 PM

Rather interesting info. Thank You for it. Hope to read something more concerning that matter in your blog. And to get new version of that software.


fincha.com @ Jun 26 2009 03:53:00 PM

Hi, how can i get the captcha to the right position?

i cant find im code the positioning script :(

may be i an deactivate some think im code and call the right function on the right place in template!?


zorex @ Jun 27 2009 06:08:12 PM

Too bad there isn’t any feature build in with the plugin for you to position the captcha. Unless you add the script into your template manually and remove the original one from the plugin file. This will be a bit complicated.


fincha.com @ Jun 29 2009 02:51:07 PM

note this for next update :)

maybe, if someone call a function in template, the captcha will ne on that position


zorex @ Jun 29 2009 06:39:35 PM

noted, will try to include this into the next release.


tiggsy @ Jun 29 2009 11:53:51 PM

Simple Captcha is great. Is it possible to have an option to require a Captcha for everyone, ie. not exclude registered users?

Leaving that aside. Is there a post anywhere explaining how you did this amazing theme? I love it. I’m intrigued because the background changes in size when you resize the portal. How did you do that?


zorex @ Jun 30 2009 10:29:53 AM

Noted, will try to implement this feature into the next release if possible.


russjman @ Jul 01 2009 06:10:01 AM

Great little plugin, but i cant use it. My wordpress installation exists in a different folder than the blog(eg. wordpress url: blah.com/wordpress, blog url: blah.com/blog ). The image makes reference only to the blog folder, not the wordpress folder. Maybe im missing some sort of configuration.


zorex @ Jul 01 2009 11:10:14 AM

Check the above update. There is a fix to encounter this problem of yours.


Sandip Saini @ Jul 04 2009 05:59:58 PM

You have a lot of good stuff here.This post is superb. You have a very good knowledge about this matter. Thanks for the tips!! It will be very helpful.

Please advise

zorex @ Jul 14 2009 02:23:12 PM

You can try to change theme and see if the problem still there. Do you have older version of simpleCAPTCHA istalled? If yes, try remove the old one and its folder


Forex Trading System @ Jul 15 2009 09:32:19 PM

Is this the old captcha. I certainly mean that 2.0 is launched?!


zorex @ Jul 15 2009 09:52:17 PM

nop, this is still version 1. Version 2 is underway

Hi there, We use wordpress for our website however people are trying to leave a comment but it keeps saying invalid security code are you able to help.

This has been happening since i installed this system…

Thanks for program though


zorex @ Jul 22 2009 10:07:15 AM

If you encounter problem such as unable to view the captcha image after you’ve activated the plugin, please check the directory to the plugin files. It should be ‘plugins/simpleCAPTCHA/’.


Fansi @ Jul 23 2009 01:21:26 PM

Can I use this anywhere in my template (i.e. in header.php or any contents in my site)? Like in my own modified form, not the standard comment form? Which code should I play with? Thank you.

Fansi


zorex @ Jul 23 2009 01:44:04 PM

the zrx_captcha.inc.php files. You go inside and you should be able to see where you can modify. You need to know some basic stuff about writing plugin for wordpress tho.


Kayleen Stevens @ Jul 24 2009 06:52:53 AM

I uploaded simple_captcha into my WordPress dashboard. It says it was successfully uploaded, but when I went to activate it, it says that the plugin does not have a valid header. What does that mean and how do I correct it?

Thank you,
Kayleen Stevens


zorex @ Jul 24 2009 10:17:52 AM

Most probably there are some conflicts btwn other plugins you installed or the theme u use. Try disable all the other plugin and use the default wordpress theme and see if the problem is solve.


mickym @ Aug 02 2009 02:10:03 PM

Hi Zorex:

When I went to the default theme, it works. But – I have a custom theme with menu’s, headers, etc.

Is there some suggestion – where I could try to make it work with a custom theme? which files etc. would I need to look at?


zorex @ Aug 03 2009 01:16:32 PM

You check the comment file in your theme directory. If your theme is compliance with the standard, it shouldn’t be any problem.


Mark @ Aug 08 2009 09:27:42 AM

Thank you for your information. Good infor

If some body need more premium wordpress theme go there: premium wordpress themes

Ab circle Pro @ Aug 25 2009 11:57:57 PM

Thanks for the plugin! Really helps to eliminate some security issues. Keep up the good work.


free mmorpg @ Aug 30 2009 05:48:47 PM

excellent plugin :P Simple and effective


Brad @ Sep 14 2009 07:11:37 AM

Hi Zorex and all

I finally got simpleCAPTCHA to work for me.
Edit the file zrx_captcha.inc.php and replace all instances of:

bloginfo(’url’)

with

bloginfo(’wpurl’)

I have my WordPress install in a sub-folder, but serve it from the DocumentRoot – bloginfo(’url’) misses out the subfolder path. bloginfo(’wpurl’) fixes it nicely.

Thanks for a great plugin.

Cheers
Brad


Gregory Blockers @ Sep 24 2009 03:53:03 PM

I think this blog is really useful and informative. Please keep up the good work it is great to read content on a blog that is not just self obsessed nonsense.
I hope I can develop a blog of this standard eventually, although I must admit I find blogging very time consuming and difficult. I wish someone would write a blog on how to produce a really interesting blog like this one.


Hans K Anderson @ Sep 25 2009 10:54:08 PM

I’m using wordpress version 2.8.4. The actual box to enter the security code is about 1/10 of the size of what it should be. Any suggestions to fix this. Thank you.


zorex @ Sep 25 2009 11:01:04 PM

Most probably your skin template cause this problem. Try changing it with another theme and see if problem still occur?


Tom @ Sep 30 2009 03:31:07 AM

I installed the plug in but it blocks all comments and does not have an option for a security code. Any ideas?


zorex @ Oct 02 2009 01:27:14 AM

Check the above added content. Most probably is the theme problem.


Amy Hewitt @ Oct 06 2009 08:54:33 AM

Hi Zorex, is it possible to use this in my headers? Thank you in advance.


zorex @ Oct 06 2009 04:08:43 PM

yea possible, but you need to do some modification to it


moonove @ Oct 22 2009 01:54:28 PM

Hi Zorex. I just updated your great plugin on my website and i dunno why but now the captcha is located between the “your website” and “your message” in the comments page :( Any idea ? Did i make something wrong ? Thank you and keep this simple and great plugin alive.


zorex @ Oct 23 2009 12:16:17 PM

Hi,

This has something to do with the theme you use. There are a lot of different kind of theme and the HTML source is not always the same, thats why it will have some issues when displaying the plugin.

what you can do is make some modifications to the theme u using now. You can try remove the line ‘Your website ‘ located under comments.


moonove @ Oct 23 2009 04:57:45 PM

Well in fact this design is homemade and i used the “default folder” wordpress 2.8.4 template to make this one. I will have a look at the comments.php file. But i tried to do that yesterday and all the design wad broken :(


zorex @ Oct 23 2009 10:11:11 PM

what you can do is move the label after the input or remove it shud be ok. I’ll try to improve this in the next version so that user can have more control on how it display


moonove @ Oct 23 2009 11:40:05 PM

Hmm unfortunately now the captcha overrides the “message” textfield.

Well, is the previous version still availabla anywhere ? It was working fine.

Maybe you could use just a text like in the template ? and it adds your content there.


zorex @ Oct 24 2009 05:51:05 PM

Yea, you can get it from http://wordpress.org/extend/plugins/simple-captcha/download/

click the other version link shud expand the list of older version.


Erick @ Oct 28 2009 04:23:13 AM

Hi, I came to know your plug in from adaphobic.com. I decided to install this because of detoxboss.com. Now my concern is I can’t install your plug in, it resulted to “The plugin does not have a valid header”. Appreciate your kind tech assitance.


zorex @ Oct 28 2009 12:05:47 PM

Can you be more specific on the error plz? Or provide a screenshot of the error?


Erick @ Oct 28 2009 01:34:47 PM

When I activate the plug in, a pop-up message displayed: “The plugin does not have a valid header”. Thanks for replying.


zorex @ Oct 28 2009 05:19:07 PM

what version of wordpress are you using?


Erick @ Oct 28 2009 07:01:07 PM

The current WP v 2.8.5


zorex @ Oct 28 2009 09:29:11 PM

I’ll look into this problem. You can try the plugin with different theme and see if problem still exists.


Erick @ Oct 28 2009 11:51:20 PM

I appreciate you for looking into this, I’ll try with another theme but it might affect my page’ performance…

nice one, thank you very much.


Thanks for sharing this great blog with everyone:-)


carlitos @ Nov 30 2009 01:49:38 PM

Hello
I would like to know how to change the number quantity to show only 3 numbers, also to change the image size a lil bit.

I already change the sinwave, and the colors to show only black, but I cant find a solution to only show 3 numbers.

Thanks for reading my comment.


zorex @ Nov 30 2009 08:03:20 PM

You have to edit from the gdimg file. There is a line on generating random integer and concatenate them to string.


carlitos @ Dec 01 2009 12:10:36 PM

Zorex, thank you so much sir. I didnt notice that line at the first.

Thanks for the great plugin.


zorex @ Dec 01 2009 06:19:05 PM

you welcome.

Hello,
The image not show,I use wordpress 2.8.


zorex @ Dec 07 2009 06:16:55 AM

Please check the extra note above, check the path. Most probably you have the wrong path

Great! This really helped me out. Thanks a lot for posting it:-) Cheers!!!!

I’m thinking about switching to drupal..Any suggestions?


Darren @ Dec 20 2009 03:10:04 PM

How can you change the size and frequency of the letters in the captcha image


Jason @ Dec 22 2009 08:20:49 PM

Not working for me, only black background, can your help me?


zorex @ Dec 23 2009 02:19:51 AM

You need to edit the file that generate the image. gdimg.php


zorex @ Dec 23 2009 02:20:46 AM

Check and see whether you have GD installed and also the path to the files are valid. Read the extra post above.

Swt, now its so hard to comment on your site. I don’t want to comment only you know. So ma fan.


Johan Boonstra @ Dec 27 2009 11:43:00 PM

For some reason this captcha is hacked. Since yesterday I am being flooded by spambots entering random usernames, websites etc, clearly an automated effort.

I’ll try changing the parameters of the gdimg.php file, maybe that’ll help. Currently Akismet is trashing all the spambots luckily :)


zorex @ Dec 28 2009 06:11:21 PM

Can you please provide me with more info? As I know if you are using the default latest plugin, there shouldn’t be any problem. Some of the spam most probably is entered by human not bot. I’ve encounter several times before but they are usually very minimal.


horlama @ Jan 10 2010 10:07:27 PM

the security code field should higher than the submit comment button, and with proper tab order set so that user can use tab button w/o using mouse click…


horlama @ Jan 10 2010 10:54:05 PM

Ahahah.. but not bad la, the plugins .. got good side also kekekek..=)


Vladimir Kiyan @ Jan 13 2010 06:23:21 PM

If captcha is not entered, wordpress 2.9.1 displays the message “you’re a robot”, but the comment passes :-(


Oleg @ Jan 14 2010 01:35:16 AM

Excellent captcha script. Was looking for a simple solution. Thanks
Oleg


dinesh sharma @ Jan 14 2010 07:49:41 PM

Hi,
Thank you for this awesome plugin.
I have been developing a plugin which requires captcha as well.
I wanted to ask if its fine for you if I use bunch of your code in my plugin in the backend.
I will provide you credits in my readme and installation file.
let me know.


Marten Davis @ Jan 15 2010 12:31:55 AM

I am getting this error when I try to install your plugin. Any suggestion?

The plugin does not have a valid header.

Marten Davis


zorex @ Jan 17 2010 10:32:27 AM

Do you have any other CAPTCHA installed? Most probably there is some conflict with the plugin you installed.


zorex @ Jan 17 2010 10:34:17 AM

You may refer my coding for your implementation, but I do not recommend you to copy it.


zorex @ Jan 17 2010 10:36:34 AM

Make sure you have all the files required. And the path is correct. Read the extra post in this entry above.


dinesh @ Jan 19 2010 09:51:53 PM

Ok, I better drop my idea of captcha at all , at this time :)


bobsoap @ Feb 04 2010 06:38:46 AM

@Vladimir Kiyan and everybody else running WP 2.9 and greater:

Wordpress 2.9 added the “trash bin” to the comments backend. The wp_set_comment_status() function no longer accepts the “delete” parameter, hence even if the wrong captcha is entered, the comment is still added to the database.

To make Simple Captcha work on Wordpress 2.9+, edit line 200 in zrx_captcha.inc.php from:

wp_set_comment_status($id, ‘delete’);

to:
wp_set_comment_status($id, ‘trash’);

Hope this helps.


birdseye @ Feb 04 2010 08:42:50 PM

Hey, great, simple plugin. Love it!
But: just installed in on http://www.eddyetlesvedettes.be/?page_id=97 and in Firefox works great. In Safari when you mouse click on the security code field; the cursor switches to previous field, same with message (textarea) field. Changed tabindex in zrx_captcha.inc.php ; but that doesn’t seem to help… Any ideas?


Yüz Estetiği @ Feb 10 2010 05:23:57 PM

been very good about this. But contains incomplete information.


Chris Ransom @ Feb 10 2010 06:05:24 PM

Works well but images are often very difficult or impossible to read.

Hi there, I installed this plugin 2 months ago and it worked just fine until 2 days ago when all of the sudden any code I enter return an error message. I realised that the $_SESSION['secret'] is empty so the session doesnt work. No matter what I do, the session is just not working. Any ideas ?
Thanks


zorex @ Mar 18 2010 01:14:06 AM

You have to check if your webserver have issues with session.


Josh @ Apr 12 2010 11:30:11 AM

I am getting invalid header error on WP 2.9.2. I looked above and could not find the solution. Could you help with this? I tried to put it on 5 other different blogs and I am getting the same error on all.


zorex @ Apr 12 2010 02:37:01 PM

I will look into this.

Hi there,

I downloaded your simple CAPTCHA plugin and added it to my website, for preventing all the spanm I get through comments. But After activating the plugin, there still is no captcha effect on the comments. How can I make this work?

greets,
Peter Boekelaar

zorex @ May 18 2010 02:03:22 PM

refer to the extra post above


Peter @ May 18 2010 09:15:43 PM

Thanks for the refer, but that\’s not it. I already had \’trash\’ thing done, and the path is ok too.
In fact, when I activate the simpleCAPTCHA plugin, commects cannot be inserted anymore. Visitors can enter a message, but it is not kept, not shown and it\’s not in the commects list in the dashboard. When I deactivate simpleCAPTCHA comments can be placed without any problem


estetik @ May 20 2010 01:50:31 AM

I had a problem with the image not showing up then I saw most other captcha plugins require GD php (not listed as a requiremetn for yours), once I installed that in linux it works.


estetik @ May 20 2010 01:59:29 AM

I appreciate you for looking into this, I’ll try with another theme but it might affect my page’ performance…
