Global Search

Hello,

the field doesn’t appear in the inside page.

I guess there are different search widgets. You added global search field only for one of them.

I create a new field named Global Search as free text.

Be sure you have
wpp_search[{YOUR_GLOBAL_SEARCH_NAME}]
name for your custom field. So your custom field’s value will be appeared in
$_REQUEST[ 'wpp_search' ]

it shows no results

get_properties() function is being used for searching properties. You should add the following ( it’s just example! ) filters:

To add your custom attribute ( field ) to query:

function my_wpp_get_properties_query( $query ) {
  if ( !empty( $_REQUEST['wpp_search']['YOUR_GLOBAL_SEARCH_NAME'] ) ) {
    $query['s'] = $_REQUEST['wpp_search']['YOUR_GLOBAL_SEARCH_NAME'];
  }
  return $query;
}
add_filter( 'wpp_get_properties_query', 'my_wpp_get_properties_query' );

To allow custom search by specific query attribute:

function my_wpp_get_properties_custom_case( $false, $meta_key ) {
  return $meta_key == 's' ? true : $false;
}
add_filter( 'wpp::get_properties::custom_case', 'my_wpp_get_properties_custom_case', 10, 2 );

Do your custom search by your custom query attribute:

function my_wpp_get_properties_custom_key( $matching_ids, $meta_key, $criteria ) {

  if ( $meta_key == 's' ) {
    $sub_query = new WP_Query(array(
      's' => $criteria,
      'post__in' => $matching_ids,
      'post_type' => 'property'
    ));

    $matching_ids = array();

    foreach( $sub_query->posts as $_post ) {
      $matching_ids[] = $_post->ID;
    }
  }

  return $matching_ids;
}
add_filter( 'wpp::get_properties::custom_key', 'my_wpp_get_properties_custom_key', 10, 3 );

Regards.

Denali theme is using native WP-Property search functionality. So the solution should work for you.

Please, be aware, you should use child theme of Denali to achieve your needs. It prevents the issues with theme upgrading in future.
