Home Forums Backend Issues (wp-admin) Hook to Google Map Init/Loader Reply To: Hook to Google Map Init/Loader

  • Hi drebbits,

    have you found a Solution to this Problem yet?

    I’m also trying to hook into the Google Maps initialisation process to Load some Geodata (LAT/LNG) from an external Database an show this position on the Google Map, when its loaded.

    **** EDIT ****
    Found a Solution for my problem, which was quit easy:

    add_filter('acf/load_value/name=geo_map', 'hook_gmap_value', 10, 3);
    function hook_gmap_value( $value, $post_id, $field ) {
        // Check if Travel-DB Entry for this Post exists
    	global $wpdb;
    	global $geo_table;
    	$db_check = $wpdb->get_var( "SELECT COUNT(*) FROM $geo_table WHERE item_id = $post_id" );
    	// DB Entry exists, get the GEO-Data and load the GoogleMap with this Data
    	if ( intval($db_check) !== 0 ) { 
    		$data = $wpdb->get_row( "SELECT * FROM $geo_table WHERE item_id = $post_id" );
    	    $value['address'] = $data->address;
    	    $value['lat'] = $data->lat;
    	    $value['lng'] = $data->lng; 	
        return $value;

    just hooking into the load_value works for me, but i’m afraid not for your problem ;-/

    best regards,
