Concrete5 Ajax Form

Improves the built-in form block so it submits via ajax. Also uses a table-less layout for easier styling, and optional "placeholder" label functionality.

REQUIRES CONCRETE 5.6 OR HIGHER!

Installation

Download the ZIP file
Unzip the downloaded file
Open the blocks folder
Move the form folder to your site's top-level blocks directory (not concrete/blocks)

That's it! Now any form blocks added to your site will automatically have ajax functionality (unless a custom template is chosen, or unless there are file upload fields in the form).

Placeholder Labels

To enable "placeholder" functionality (so field labels appear inside the fields themselves), set the $enablePlaceholders variable to true near the top of blocks/form/controller.php.

Spam Honeypot

A basic "honeypot" method (e.g. http://stackoverflow.com/q/3622433/477513) is enabled by default to prevent spam submissions. You can disable this by setting the $enableSpamHoneypot variable to false near the top of blocks/form/controller.php.

Google Analytics Event Tracking

If you're tracking site events with Google Analytics, you'll want to add some code like the following to blocks/form/view.php, directly under the } else if (response.success) { line:

if ('undefined' !== typeof _gaq) {
	_gaq.push(['_trackEvent', 'Forms', 'Submitted', '<?php echo addslashes($formName); ?>']);
}

PHP Errors/Warnings?

Some users have reported getting the following error on pages that have a form block: Warning: Invalid argument supplied for foreach() in /PATH/TO/YOUR/SITE/blocks/form/view.php on line 111. This error is caused by the "Overrides Cache" (it gets confused if there was already a form block on the page and then you add this ajax form template to your site). To resolve the problem, temporarily disable the Overrides Cache (via Dashbard > System & Settings > Cache & Speed Settings), then visit / reload any pages on your site that have a form block on them, then re-enabled the overrides cache. Or better yet, if the site is in development, you should just leave all caching disabled until you're ready to go live.
