Question

I have added the client side validations on a form using jQuery’s validate() function and assigned rules and it shows the error messages in Red color below the respected fields. I want to show same error messages after performing server side validations done in PHP. Please help.

You’ll have to perform that logic with PHP, in a sense replicating all that jQuery’s validate() plugin does. I generally run through a series of tests, and add errors to an array:

$errors = array();
if (!valid_name($firstname)) $errors[] = "Please provide your first name.";
if (!valid_email($email))    $errors[] = "Please provide a valid email address.";

Then, after all of my rules, I’ll decide whether or not to post the data or show the errors:

if (count($errors) > 0) {
  show_errors($errors);
  show_form();
} else {
  submit_data();
}

This is a format that has worked well for me.
