Boilerplate Code
Use the boilerplate code to start using the filter, and add your own logic to modify the first argument and return it.
fwd_add_filter('jreviews:permission:listing.set_listing_title_alias', function($canSetTitleAlias, $user, $listing)
{
// Your code here
return $canSetTitleAlias;
}, 20, 3);
The , 20, N after your callback are the hook priority and the number of arguments your callback accepts. By default, a hook passes your callback only its first argument; for a filter, that is the value being filtered, so a simple function($value) { ... } needs nothing extra. If your callback declares more parameters, such as function($value, $listing) { ... }, you must add N (the parameter count, 2 here). Because N is the fourth argument to fwd_add_filter() or fwd_add_action(), you must also pass the priority (20 is the default). Leaving these off when your callback expects extra parameters causes a Too few arguments to function ... fatal error.
