Definition: delete-entry.php:7
$meta_keys
Define the keys to be parsed by the gravityview/data/parse/meta_keys hook.
fix_posted_fields()
ACF needs $_POST[&#39;fields&#39;] to be an array.
_gravityview_process_posted_fields()
Maybe convert jQuery-serialized fields into array, otherwise return $_POST[&#39;fields&#39;] array...
Abstract class that makes it easy for plugins and themes to register no-conflict scripts and styles...
