jreviews:validation_rules:listing.url_media_upload
Filters validation rules when users upload media files from remote URLs to listings. Allows adding custom validation rules beyond the default file type, size, and URL format checks.
You need to have a working knowledge of Hooks before you get started.
Fires when validating URL-based file uploads for listings, before the remote file is fetched

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:validation_rules:listing.url_media_upload', function($rules, $mediable, $mediaType, $request)
{
// Your code here
return $rules;
}, 20, 4);
The , 20, N after your callback are the hook priority and the number of arguments your callback accepts. By default, a hook passes your callback only its first argument; for a filter, that is the value being filtered, so a simple function($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.
