Creating your own filter call
There must be at least 1 argument passed (the first argument is intended to be the value that is to be filtered by the handling functions)
The function other plugins and theme can add if they want to receive your special filter call
//A filter handling function you want to call
add_filter( 'my_filter_name', 'handle_my_filter_name', 10, 3 ); //FilterName, CallbackFunction, Priority (default10), Number of arguments expected (default/min 1)
//add_filter( 'my_filter_name', '\MyNamespaceName\handle_my_filter_name', 10, 3 ); //<<<If you are using a namespace
function handle_my_filter_name($Argument1, $Argument2, $Argument3)
{
//Do something...
return($MyVariable1);
}The call you do that will trigger anywhere my_filter_name has been added
//Calling it
$Result = apply_filters('my_filter_name', $Argument1, $Argument2, $Argument3);
