Go reCAPTCHA - programmatic recaptcha forms for WP.

Requirements

Software: none. You will need keys from Google's reCAPTCHA site.

While not required, this was originally created for use with go-contact and some of the design decisions were made for working with shortcodes and multiple instances on a single page. Really, we're just saying they work well together. In fact, go-contact requires go-reCAPTCHA.

Hacking

You can create your own templates to use for the reCAPTCHA form. There are two example forms in the components/templates folder.

You can modify the response messages in components/class-go-recaptcha.php

Usage

You have to set the recaptcha private and public keys for this to work. If you are using go-config that's the best way to go. If not you will have to edit the class-go-recaptcha.php file to insert your keys.

Once that is set up, you call a reCAPTCHA form using something along the lines of:

<fieldset class="recaptcha">
	<?php
		if ( function_exists( 'go_recaptcha' ) )
		{
    		echo go_recaptcha()->get_inputs();
		}//end if
	?>
</fieldset>

and validate the recaptcha using something like:

if ( function_exists( 'go_recaptcha' ) && ! go_recaptcha()->check_request() )
{
	$return['error'] = go_recaptcha()->get_message_text();
	echo json_encode( $return );
	die;
} // END if
