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,
serio
