Carlos,

What is the code that you’re using in the template that displays the single event that generates the add to cart link?

Hi Carlos,

The last update from version 3.36.1 to 3.36.2 did not affect the add attendees to database functionality. It was a very minor update that added two things:

1) An option was added to Event Espresso>General Settings that affects a promo code setting in the event editor.

2) A script that handles the return from the payment gateway after payment was adjusted to account for if there is a free event added to the cart.

Where there could be a potential cause is if any functions from cart.php or add_attendees_to_db.php were customized based on the functions from Event Espresso version 3.1.35 or earlier and copied to a custom functions file. There were some code changes going from .35 to .36 that dealt with preventing overbooking of an event. Can you check to see if there are any custom functions that override core functions that handle the registration process? Custom functions can run from the theme’s functions.php file, a custom snippets plugin, or from /wp-content/uploads/espresso/custom_functions.php.

I have tried testing this out a few different ways on a test server running a stock 3.1.36.2 install of Event Espresso and I haven’t been able to reproduce this, so any information you can give on what functions if any have been customized may help narrow down the issue.

Hi Carlos,

If you can post the contents of your custom template in a pastebin and link to it here we’ll be glad to take a look to see if we can spot something missing or a potential cause. 🙂

I set this up on my test server, and it looks like it goes through to the payment page, and then I get this message:

Sorry, you have requested 2 ticket(s) for ‘Event #7’, but only 1 remains(s). All other tickets for this event have been sold, or are being purchased. You may want to try registering later, in case someone doesn’t finish registering or cancels

Is that the same issue you are seeing?

Sorry, I was testing with an Alpha copy of 3.1.37. When I switched to the current version and retested, I got the same results as you. We’ve worked out a solution that appears to be working. It requires changes to 2 files:
1: includes/functions/cart.php, starting at line 195 should be changed to:

$attendee_quantity = 0;
				
				if ( isset( $_POST['price_id'][$event_id] )) {
					$price_id = $_POST['price_id'][$event_id];
				} else {
					return FALSE;
				}

				if (is_array($price_id)) {
					foreach ($price_id as $_price_id => $val) {
						//assign the event type and the quantity
						$attendee_quantity += $updated_events_in_session[$event_id]['price_id'][$_price_id]['attendee_quantity'] = esc_sql($val);
						$updated_events_in_session[$event_id]['price_id'][$_price_id]['price_type'] = $events_in_session[$event_id]['price_id'][$_price_id]['price_type'];

					}
				} else if ( $price_id !== FALSE ) {

Note that line 195 and 206 are changed, and what was line 209 is deleted.
2: includes/process-registration/add_attendees_to_db.php, starting at line 713:

$return_data = event_espresso_add_attendees_to_db( $event_id, $session_vars, TRUE );
								if (!empty($return_data['registration_id'])) $session_vars['data']['attendee_quantity']--;

That second line is a new line of code. The first line is unchanged, I just put it in to give you a reference as to where to put the second line.
We’ll be testing this to try to get a hotfix release out to address the issue (3.1.36.3), so any feedback you can provide from testing these changes on your end would be helpful. If you have trouble applying the changes, let us know by filling out the form here (be sure to include ftp credentials), and we can apply them for you.

Hi Carlos,

I will mark this thread as resolved. If any further issues arise, please start a new thread and link back to this one. Thanks.
