Unsetting DataObjects when iterating through a DataObjectSet
1 July 2009 at 9:04pm
Hello.
I have been following the tutorials and I am using one of the functions listed to get the latest news items on different pages.
However, I only want to show the news items that the user has access to. Figuring out if the current item could be viewed was really easy but getting rid of the offending news items proved to be harder.I ended up creating a new DataObjectSet and putting the DataObjects that the user can view in the new set and then returning that, but I am thinking that there must be an easy way to unset a DataObject during a foreach loop but I just can't find it.
Also is there an easy way to restrict a DataObject::get() to only get the records that the user is allowed to view so I don't have to filter after the fact?
Kindly, Marcus.

Not well, I always just do a foreach loop after it if($object->can('View')) ...;
To unset it can't you just call remove? I don't think PHP will complain about concurrency errors with the following
foreach($pages as $page) {
$pages->remove($page);
}
