Attendee limit on registration addon

The tutorial guides you on how you can limit the number of registrations in the Registration addon.

Here are the steps you need to take:

1. There are two ways in which you can do this:

Firstly, you can add a new field called “Registration Limit” from the Field Editor in your backend.

b. You can add a new field in functions.php by following this tutorial: “Event submission form Documentation.”

After that, you can add the code mentioned below.

2. You can go to your functions file by following the given path:

yourprojectname\wp-content\themes\event-listing\functions.php

3. Create a Function

       add_filter('event_manager_registration_addon_form','custom_event_registration_form_addon',100);

4. Add the code:

/**
* @return boolean 
*/

function custom_event_registration_form_addon(){
          $event_id = get_the_ID();
          $args = apply_filters( 'event_manager_custom_event_registrations_args', array('post_type' => 'event_registration',
          'post_status' => array_diff( array_merge( array_keys( get_event_registration_statuses() ), array( 'publish' ) ), array( 
          'archived' ) ),'ignore_sticky_posts' => 1,'posts_per_page' => '-1','post_parent' => $event_id
          ) );

         $the_query = new WP_Query( $args );

//change the 5 to your limitation of attendee

         $registration_limit = get_post_meta($event_id,'_registration_limit',true);

//_registration_limit is a field name

         if($registration_limit >= 0 && $the_query->found_posts >= $registration_limit ){

//if you want to show notice then you can keep below line otherwise remove.

        echo '<div class="wpem-alert wpem-alert-warning">The registration for this event is full.</div>';
     return false;
     }
     return true;
     }
