Is there any way to set things so that if a user tries to delete a page there is a check made on the dependancies. I want a message ideally that says if you delete these pages links on these pages will be brokem. Then the user has the option of either deleting the page and breaking the links or cancalling the deletion.

I don't really want to lock the file/page because the user deleting the page might not own the dependant files, so can't update them.

loader_import ('cms.Versioning.Rex');

// limit to delete action and to web pages
if ($parameters['transition'] == 'delete' && $parameters['collection'] == 'sitellite_page') {
    // get a count of pages linking to this one
    $count = db_shift ('select count(*) from sitellite_page where body like ?', '%/' . $parameters['key'] . '"');

    if ($count) {
        // there are links, restore and alert
        $rex = new Rex ('sitellite_page');
        $history = $rex->getHistory ($parameters['key'], false, 1);
        $rex->restore ($parameters['key'], $history[0]->sv_autoid, array ());

        echo $count . ' pages link to this one still.';
        exit;
    }
}

Another option would be to add a new transition in the workflow of the delete action to be triggered before it's executed. That's probably more logical since it doesn't delete the page then check. I'll see about adding a few more of these workflow triggers for the next beta update, since they're easy to add and that would make it a bit more flexible.
