The Captcha plugin adds a captcha form into web pages. This captcha can be used for login, registration, password recovery, comments forms. It protects your website from spammers by means of math logic, easily understandable by human beings. All you need is to do one of the three basic maths actions – add, subtract and multiply. You will not have to spend your precious time on annoying attempts to understand hard-to-read words, combinations of letters or surreal pictures.

Presently, there are two versions of Captcha plugin available – free version, and Captcha Pro. The first one comes packed with the basic features, however, if you want to extend the plugin’s functionality, you can always purchase the Pro version, which includes premium possibilities, such as compatibility with BuddyPress (Registration form, Comments form, “Create a Group” form), Contact Form 7 and Subscriber.

Requires WordPress at least: 3.1

Technical support

Dear users, our plugins are available for free download. If you have any questions or recommendations regarding the functionality of our plugins (existing options, new options, current issues), please feel free to contact us. Please note that we accept requests in English only. All messages in another languages won’t be accepted. If you notice any bugs in the plugins, you can notify us about it and we’ll investigate and fix the issue then. Your request should contain URL of the website, issues description and WordPress admin panel credentials. Moreover we can customize the plugin according to your requirements. It’s a paid service (as a rule it costs $40, but the price can vary depending on the amount of the necessary changes and their complexity). Please note that we could also include this or that feature (developed for you) in the next release and share with the other users then. We can fix some things for free for the users who provide translation of our plugin into their native language (this should be a new translation of a certain plugin).

  1. 1. Upload the captcha or captcha-pro folder to the /wp-content/plugins/ directory.
  2. 2. Activate the plugin via the ‘Plugins’ menu in WordPress.
  3. 3. Plugin settings are located in ‘BWS Plugins’, ‘Captcha’/’Captcha Pro’.

How to change a captcha label

You should go to the Settings page and change the value in the ‘CAPTCHA label in the form’ field.

During the settings saving I get the error: ‘Please select one point in the blocks “Math actions” and “Complexity Level”‘. What is this?

For stable work of the Captcha plugin you should select at least one item in the ‘Math actions’ block and select ‘Complexity Level’ on the Settings page, because math expression should consist of at least 1 math sign and parts of math expression should be displayed like words or numbers or both of them.

Missing CAPTCHA on the comment form?

You might have a theme where comments.php is not coded properly.
Wopdpress version matters.
(WP2 series) Your theme must have a tag <?php do_action('comment_form', $post->ID); ?> inside the file /wp-content/themes/[your_theme]/comments.php.
Most WP2 themes already have it. The best place to put this tag is before the comment textarea, you can move it up if it is below the comment textarea.
(WP3 series) WP3 has a new function comment_form inside of /wp-includes/comment-template.php.
Your theme is probably not up-to-date to call that function from comments.php.
WP3 theme does not need the code line do_action('comment_form'... inside of /wp-content/themes/[your_theme]/comments.php.
Instead it uses a new function call inside of comments.php: <?php comment_form(); ?>
If you have WP3 and captcha is still missing, make sure your theme has <?php comment_form(); ?>
inside of /wp-content/themes/[your_theme]/comments.php (please check the Twenty Ten theme’s comments.php for proper example)

How to use the other language files with CAPTCHA?

Here is an example for German language files.

  1. 1. In order to use another language for WordPress it is necessary to set a WordPress version to the required language and in the configuration wp file – `wp-config.php` in the line `define('WPLANG', '');` you should enter `define('WPLANG', 'de_DE');`. If everything is done properly the admin panel will be in German.
  2. 2. Make sure the files `de_DE.po` and `de_DE.mo` are present in the plugin (the folder “Languages” in the plugin root).
  3. 3. If there are no such files you should copy the other files from this folder (for example, for Russian or Italian) and rename them (you should write `de_DE` instead of `ru_RU` in both files).
  4. 4. The files can be edited with the help of the program Poedit – http://www.poedit.net/download.php – please download this program, install it, open the file using this program (the required language file) and for each line in English you should write translation in German.
  5. 5. If everything is done properly all lines will be in German in the admin panel and in the front-end.

I would like to add Captcha Pro to the Contact Form 7. How can I do this?

  1. 1. Make sure you enabled “Contact Form 7″ on the Captcha settings page.
  2. 2. Go to “Contact Form 7″ form where you want to make use of Captcha.
  3. 3. Find a dropdown menu with the form fields, select BWS CAPTCHA and insert it into your form.

I would like to add Captcha to the custom form on my website. How can I do this?

  1. 1. Install the Captcha plugin and activate it.
  2. 2. Open the file with the form (where you would like to add captcha to).
  3. 3. Find a place to insert the code for the captcha output.
  4. Insert the necessary lines:

if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom() }; if( function_exists( 'cptchpr_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptchpr_display_captcha_custom() };

If the form is HTML you should insert the line with the PHP tags:

<?php if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptch_display_captcha_custom(); } if( function_exists( 'cptchpr_display_captcha_custom' ) ) { echo "<input type='hidden' name='cntctfrm_contact_action' value='true' />"; echo cptchpr_display_captcha_custom(); } ?>

Then you should add the lines to the function of the entered data checking

if ( ( function_exists( 'cptch_check_custom_form' ) && cptch_check_custom_form() !== true ) || ( function_exists( 'cptchpr_check_custom_form' ) && cptchpr_check_custom_form() !== true ) ) echo "Please complete the CAPTCHA.";

or

<?php if ( ( function_exists( 'cptch_check_custom_form' ) && cptch_check_custom_form() !== true ) || ( function_exists( 'cptchpr_check_custom_form' ) && cptchpr_check_custom_form() !== true ) ) echo "Please complete the CAPTCHA." ?>

You could add this line to the variable and display this variable in the required place instead of echo “Please complete the CAPTCHA.”. If there is a variable (responsible for the errors output) in the check function, this phrase can be added to this variable. If the function returns ‘true’, it means that you have entered captcha properly. In all other cases the function will return ‘false’.

I have some problems with the plugin’s work. What Information should I provide to receive proper support?

Please make sure that the problem hasn’t been discussed yet on our forum (http://support.bestwebsoft.com). If no, please provide the following data along with your problem’s description:

  1. 1. the link to the page where the problem occurs.
  2. 2. the name of the plugin and its version. If you are using a pro version – your order number.
  3. 3. the version of your WordPress installation.
  4. 4. copy and paste into the message your system status report.

    I just purchased Captcha Pro and I was trying to add it to my custom contact form but I could not get it to appear. I am using the local business theme for WordPress and all you need to do generally is add the code to the page. But, nothing happens. Could you please advise?

      Hi Robert,

      Could you please specify the code you have added?
      If you are usng a custom contact form and want Captcha to be displayed in it, please follow the instructions below.

      = I would like to add Captcha to custom form on my website. How can I do this? =
      1. Install the Captcha plugin and activate it.
      2. Open the file with the form (where you would like to add the captcha to).
      3. Find a place to insert the code for the captcha output.
      4. Insert the necessary lines:
      `if( function_exists( ‘cptch_display_captcha_custom’ ) ) { echo ““; echo cptch_display_captcha_custom() } ;`
      If the form is HTML you should insert the line with the PHP tags:
      `< ?php if( function_exists( 'cptch_display_captcha_custom' ) ) { echo "“; echo cptch_display_captcha_custom(); } ?>`
      5. Then you should add the lines to the function of the entered data checking
      `if( function_exists( ‘cptch_check_custom_form’ ) && cptch_check_custom_form() !== true ) echo “Please complete the CAPTCHA.”`
      or
      `< ?php if( function_exists( 'cptch_check_custom_form' ) && cptch_check_custom_form() !== true ) echo "Please complete the CAPTCHA." ?>`
      You could add this line to the variable and display this variable in the required place instead of `echo “Please complete the CAPTCHA.”`. If there is a variable (responsible for the errors output) in the check function, this phrase can be added to this variable. If the function returns ‘true’, it means that you have entered captcha properly. In all other cases the function will return ‘false’.

      Sincerely

        Anna,

        I saw those directions and I know you said to paste the code into the plugin code directly, but where exactly am I supposed to paste it. I know the code has to be pasted in the right spot but I am not sure where.

          Dear Robert,

          “contact form plugin for WordPress” – if you mean the plugin of our company (http://wordpress.org/plugins/contact-form-plugin/), there is no need to add anything – you should only enable captcha display for contact form on the settings page.

          If you mean any other contact form (except Contact Form and Contact Form 7), yes, it is necessary to make changes so that captcha could be displayed and work correctly. Generally, It is necessary to add Captcha Pro code to the template of the file where the custom contact form is located, but unfortunately there isn’t any definite place where this code should be added, since there is a wide range of contact froms and any of them is unique as well as the place to add the code. We can assist you, but it is a paid service since we need some time to analyze the form and implement captcha there.

          You may also use this instruction:

          `< ?php if( function_exists( 'cptchpr_display_captcha_custom' ) ) { echo "“; echo cptchpr_display_captcha_custom(); } ?>`

    Hello!
    Wonderful plugin :) however, the CAPTCHA field still doesn’t appear for me. I am using WP3.9.2 with Bouquet theme. I have thoroughly read your FAQ and I do have the inside my comments.php file. Why does it still not work?
    Thank you in advance for your help.

    • Anna said:

      Hi Tatiana,

      Captcha will only be displayed and work correctly if you are using standard registration, login, comments form pages. In case of using custom forms and pages it will be necessary to make changes in them so that captcha could be displayed and work correctly.
      On page http://penseesduneshoesaholic.com/me-contacter/ there is a custom contact form. On order to implement captcha there, please follow the instructions below.

    HI,

    Wonderfull plugin.
    Unfortunally the question itself is listed behind the phrase before!
    i.e. http://www.duurzaamsamen.nl/contact/ where it is listed behind the leave a message box at the bottum of the screen.

    Thanks in advance.

    Coert

    • Alina said:

      Dear Coert,

      We navigated by the following link http://www.duurzaamsamen.nl/contact/. The Captcha block (which is generated by our plugin) is displayed only with the comments form. Also, it is displayed correctly (i.e. the text field is located where it is supposed to be). As for the Captcha block with the contact form, it has not been generated by our plugin.

      Regards
