MT::App::CMS::cmsviewpermission_filter.$type

This callback is invoked when a user is attempting to view an object of a designated type (as specified by $type) from within the Movable Type application. The intent of this callback is to give plugins the opportunity to revoke the current user’s permission to view the correlated object.

Input Parameters

• $cb - a reference to the current MT::Callback object handling this event.
• $app - a reference to the MT::App::CMS object processing the request.
• $id - the ID of the object, if it already exists, or “undef” if it is a new object with this request.
• $obj_promise - a promise for the object itself. You can use $obj_promise->force to get ahold of the object, if you need it, but typically you won’t need it.

Return Value

A boolean (true/false) value. Returning false will revoke the current user’s ability to view the corresponding object.

Example Handler

sub handler {
    my ($cb, $app, $id, $obj_promise) = @_;
    if ($id % 2 == 0) { return 0; }
    return 1;
}
