Hi,

Pre applying will be quite hard, but pre-populating is fairly easy.

Add the following function to wp-content/uploads/espresso/custom_functions.php (you may need to create this if it does not already exist, or use a custom plugin).

<?php //delete this if it already exists at the top of the custom_functions.php file

   function event_espresso_coupon_registration_page( $use_coupon_code = 'N', $event_id, $class =' ee-reg-page-text-input ', $multi_reg = FALSE ) {
	
        global $espresso_premium;
        if ( ! $espresso_premium ) {
			return;
		}
     
     $x = $_GET['promo'];
    if( !isset($x) ) { $x = ''; }

        if ( in_array($use_coupon_code,array("Y", "G", "A")) ) {

            $multi_reg_adjust = $multi_reg ? "[$event_id]" : '';	 

            $output ='
	<p class="event_form_field coupon_code" id="coupon_code-' . $event_id . '">
		<label for="coupon_code" class="inline">' . __('Promo Code', 'event_espresso') . ':</label>
					<input type="text" class="espresso-coupon-code ' . $class . '" name="event_espresso_coupon_code'. $multi_reg_adjust . '" id="coupon_code-' . $event_id . '" value="' . $x . '">
	</p>';
			
        } else {
			$output = '';
		}
		
        return $output;
		
    }

Now if you add &promo=promocode to the end of the URL it will grab that code and insert it into the promo field.

Hello,

This should be added to a site specific plugin:

This will ensure that it is not lost on a software or theme update.
