I'm trying to upgrade my old application that had some gallery hooks. I'm trying to turning the old hooks into Listeners, but not all events are firing as expected.

I created a content listener for the class \IPS\gallery\Album\Item, but only "onDelete" and "onView" are firing, why onBeforeCreateOrEdit isn't'?

What I'm expecting is to see this log to appear the moment I create a new album.

class albumItemHook extends ContentListenerType
{

    public static string $class = \IPS\gallery\Album\Item::class;

     public function onBeforeCreateOrEdit( ContentClass $object, array $values, bool $new = FALSE ): void
     {
         Log::log( 'before' );
     }
}

When the album is created (or modified), it uses the Album object (which is a node), rather than the Album Item object. You'll need to work with a NodeListener instead.

But the NodeListener class only has the "onDelete" method as available event, or am I missing something?

/**
 * @method onDelete( Model $node ) : void
 */
class NodeListenerType extends ListenerType
{
    /**
     * @brief  Determine whether this listener requires an explicitly set class
     *           Example: MemberListeners are always for \IPS\Member, but ContentListeners
     *           will require a specific class.
     * @var bool
     */
    public static bool $requiresClassDeclaration = TRUE;

    /**
     * Defines the classes that are supported by each Listener Type
     * When a new Listener Type is created, we must specify which
     * classes are valid (e.g. \IPS\Content, \IPS\Member).
     *
     * @var array
     */
    protected static array $supportedBaseClasses = array(
       Model::class
    );
}

You're correct, sorry. Try UINode extension, that should have what you're looking for.

Yes! That works now! Just one last question if I may: how do I add a new field in the modal to create a new album? all the elements returned by my "formElements" function appear only in the "edit" modal.

Yes.... I don't know if I would call that a bug, more like an oversight. The album creation form doesn't really follow the same logic, and it's not a straightforward fix. I'll log it, but it definitely won't be in the next release (possibly 5.0.4).

Alright, thank you. I guess I'll just manually edit the template for now

I wouldn't advise this. You technically can't manually edit the template - any changes you make wouldn't carry over to a live system, and they would be overwritten with the next update.
