The em_booking_save filter passes up to 3 variables. When you call add_filter the default is to only to pass in 1 variable (which is type boolean). Use the following:
add_filter('em_booking_save', 'my_booking_save_filter', 10, 3);
function my_booking_save_filter($errors, $EM_Booking, $update) {
$event_id = $EM_Booking->event_id;
// your conditional logic goes here
return $errors;
}
The $update variable is true if this is a change to an existing booking.
When using this method i get the following error when someone does a booking.
“message”: “Uncaught Error: Too few arguments to function {closure}(), 1 passed in /wp-includes/class-wp-hook.php on line 326 and exactly 3 expected in functions.php on line 387”,
I tried this and it worked fine (I did not get the error you show).
The calls to apply_filter for the em_booking_save filter are located on lines 374 and 395 of events-manager/classes/em-booking.php:
apply_filters('em_booking_save', ( count($this->errors) == 0 ), $this, $update);
apply_filters('em_booking_save', false, $this, false);
You can see that 3 arguments are being passed. Either the events manager code was modified or there is some other place outside of the events manager plugin that is calling apply_filters on em_booking_save without the 3 parameters on your website.
Thanks for you response! You are totally right.
Above this code i had another piece of code which came from this topic:
https://ww.wp.xz.cn/support/topic/hook-after-registration-for-event/
After changing that function to $status, $EM_Booking, $update and adding return $status in both functions it’s working as intended!
