Add custom field in Search filter

Creating a custom event search filter

WP Event Manager’s [Events] shortcode will show a search filter on top. if you want to add a custom filter in the top section you can add it via hook or overriding via template files.

It is possible to add new filters to the search form by adding a field and then modifying the search queries using filters.

1. Open your child theme,
2. Add the code into the funtions.php file.

   Here is an example field:

   <?php
   /**
    * Adding via filter or you can directly add-in a template file
    */
      add_action( 'event_manager_event_filters_search_events_end', 'filter_by_country_field' );
      function filter_by_country_field() {
   ?>
   <?php   
    <div class="search_event_types">
           <label for="search_event_types"><?php _e( 'Country', 'event_manager' ); ?></label>
           <select name="filter_by_country" class="event-manager-filter">
               <option value=""><?php _e( 'Select country', 'event_manager' ); ?></option>
               <option value="de"><?php _e( 'Germany', 'event_manager' ); ?></option>
               <option value="in"><?php _e( 'India', 'event_manager' ); ?></option>
               <option value="us"><?php _e( 'USA', 'event_manager' ); ?></option>
           </select>
       </div>
   }
   ?>
   
   <?php
   /**
    * This code gets your posted field and modifies the event search query
    */
   add_filter( 'event_manager_get_listings', 'filter_by_country_field_query_args', 10, 2 );
   function filter_by_country_field_query_args( $query_args, $args ) {
       if ( isset( $_POST['form_data'] ) ) {
           parse_str( $_POST['form_data'], $form_data );
           // If this is set, we are filtering by country
           if ( ! empty( $form_data['filter_by_country'] ) ) {
               $event_country = sanitize_text_field( $form_data['filter_by_country'] );
               $query_args['meta_query'][] = array(
                           'key'     => '_event_country',
                           'value'   => $event_country,
                           );
           }
       }
       return $query_args;
   }
   ?>
