mylists:on-favorites-migration

Filters a favorite migration row before it is written to a MyLists list. Also fired via the legacy `Clickfwd\Hook` system as `mylists:on-favorites-migration` for V5 compatibility (the legacy call is slated for removal in V7).

You need to have a working knowledge of Hooks before you get started.

#Parameters

#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('mylists:on-favorites-migration', function($row, $listing)
{
    // Your code here
    
    return $row;
}, 20, 2);

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.
