I want to validate user entries on a WordPress post upon hitting the submit button, display an error message is there are problems, and submit the form if everything is OK.

The following JavaScript issues the AJAX request, and was supposed to continue submitting the form upon successful checking, but it doesn't: jQuery(document).ready(function() { jQuery('#post').submit(function() { var form_data = jQuery('#post').serializeArray(); var data = { action: 'ep_pre_submit_validation',
