Really Simple CAPTCHA

Description

Really Simple CAPTCHA is a CAPTCHA module intended for integration with other plugins, particularly Contact Form 7. This plugin does not operate independently and is designed to enhance the security of forms by generating CAPTCHA challenges.

It is important to note that Really Simple CAPTCHA is not highly secure, as its name suggests. For those requiring stronger security measures, alternative solutions should be considered.

The plugin functions by creating two files for each CAPTCHA: an image file and a text file containing the correct answer. This method avoids using PHP sessions, reducing potential conflicts within WordPress.

To implement Really Simple CAPTCHA in your plugin, create an instance of the ReallySimpleCaptcha class and customize it as needed. You can generate random words for CAPTCHA and manage the image and text files easily.

This plugin is straightforward to use and can be integrated into any WordPress site requiring basic CAPTCHA functionality.

For a live demonstration, visit the Contact Form 7 website.

FAQ

Really Simple CAPTCHA needs GD and FreeType library installed on your server. Ask your server administrator if they are installed.

Also, make the temporary file folder writable. The location of the temporary file folder is managed by the instance variable tmp_dir of ReallySimpleCaptcha class. Note that the setting varies depending on the calling plugin. For example, Contact Form 7 uses wp-contents/uploads/wpcf7_captcha as the temporary folder basically, but it can use different folder depending on your settings.
