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!
- Download the ZIP file
- Unzip the downloaded file
- Open the
blocksfolder - Move the
formfolder to your site's top-levelblocksdirectory (notconcrete/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).
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.
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 $enableSpamHoneypot variable to false near the top of blocks/form/controller.php.
If you're tracking site events with Google Analytics, you'll want to add some code like the following to blocks/form/view.php, directly under the } else if (response.success) { line:
if ('undefined' !== typeof _gaq) {
_gaq.push(['_trackEvent', 'Forms', 'Submitted', '<?php echo addslashes($formName); ?>']);
}
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.
