Hi Clair,

Normally what would happen is the prior registration would be overwritten because it’s all happening in the same PHP session. That said, if the server isn’t configured to allow PHP sessions, then you might see the double entries in the database.

The first thing to check would be if PHP Sessions are enabled, and the Event Espresso > System Status page has this information.

The other thing you can try is swapping out the contents of the event-espresso/scripts/validation.js file with the following:

$jaer = jQuery.noConflict();
	jQuery(document).ready(function($jaer) {
	jQuery(function(){
		//Registration form validation
		jQuery('#registration_form').validate({
			submitHandler:function(form){
				alert("Please wait for the registration form to process");
       			$('.btn_event_form_submit').attr('disabled','disabled');
   			}
		})
	});
});

You can try the above with or without the alert on line 7. The alert alone would likely prevent a second submission.

Hi Clair, the code I gave you should disable button after the first click *if the form passes validation*. If it disabled it after the first click only, then people wouldn’t be able to continue if they didn’t fill out a required form.

The alert on line 7 is optional and you can remove line 7. I suggested earlier to try it with and without the alert.

Can you point us to a registration form that’s currently active so we can investigate further?

Hi Clair,

Please review and change the code in the validation script to what follows:

$jaer = jQuery.noConflict();
	jQuery(document).ready(function($jaer) {
		jQuery('form .btn_event_form_submit').css("color", "green");
	jQuery(function(){
		//Registration form validation
		jQuery('#registration_form').validate({
			submitHandler:function(form){
       			jQuery('form input[type=submit]').attr('disabled','disabled').css("color", "red");
       			form.submit();
   			}
		})
	});
});

Please note a few adjustments to the script and that there’s a few places where we add the .css method to change the color of the button text from green (submit button active) to red (submit button is disabled).

The color changes are intended to be temporary to help verify the script is working. You can remove those after testing.
