Hi,

I’ve coded an ajax call for checking if the email is already registered for the specific event (and throws a simple javascript alert if already found otherwise continue to payment step). This works fine for data that is pre-filled for logged in users. But if the form is blank on page load and the users fill in their details and submit it throws an error that the fields are required. Why is it not submitting the data that is filled by the user.

My ajax call javascript:

jQuery(document).ready(function($){
	$('#spco-go-to-step-payment_options-submit').on('click',function(e){
		
		
		e.preventDefault();
		e.stopPropagation();
		
		var email = $('.ee-reg-qstn-email input').val();
		
		var event =  $('.big-event-title-hdr').attr('id');
		event = event.substr(event.length - 4,4); // this gets the event id from the heading id attribute
		
		$.ajax(
		{
			url : postdetails.ajax_url,
			type : 'post',
			data : {
				action : 'my_action',
				user_email : email,
				event_id : event
			},
			success : function( response ) {
				if (response == 'false')
				{
					$('#ee-spco-attendee_information-reg-step-form').submit();	
				}
				else
				{
					alert('Your email is already in use for this event. Please try again');
				}				
			},
			error : function()
			{
				alert('There was a problem with your registration, please try again.');
			}
			
		});

	});
});

My ajax PHP:

add_action('wp_enqueue_scripts', 'pia_ajax_add_scripts');
function pia_ajax_add_scripts()
{
	wp_enqueue_script('ajaxcalls', get_stylesheet_directory_uri().'/js/ajax-registration.js');
	wp_localize_script( 'ajaxcalls', 'postdetails', array('ajax_url' => admin_url( 'admin-ajax.php' )));
}

add_action('wp_ajax_my_action', 'my_action_callback');
add_action('wp_ajax_nopriv_my_action', 'my_action_callback');
function my_action_callback() 
{
    global $wpdb; 
	 $evt_id = $_POST['event_id'];
	$results = $wpdb->get_results('
	SELECT ATT_email FROM wp_esp_attendee_meta 
	INNER JOIN wp_esp_registration ON wp_esp_attendee_meta.ATT_ID = wp_esp_registration.ATT_ID 
	WHERE wp_esp_registration.EVT_ID = '.$evt_id
	);
    $email = $_POST['user_email'];
	$registered = 'false';
	foreach ($results as $result)
	{
		if ($email== $result->ATT_email)
		{
			$registered = 'true';
			
		} 
	}
   
	
    echo $registered;
    exit(); // this is required to return a proper result & exit is faster than die();
}
