Keep Users from Deleting Content

I can keep users from deleting articles, but I can't find a way to keep them from deleting content in the articles. Is there a way to be this granular with User Settings?

I don't know how to make this granular to the point that you are checking user and group permissions -- you'll probably have to reverse engineer something. But a quick and dirty way is to disable it for non-admins.

Code:

---

// You can put this in dcaconfig
if( !$this->User->isAdmin )
{
        // Non-admins can't copy
        unset( $GLOBALS['TL_DCA']['tl_content']['list']['operations']['copy'] );

        // Non-admins can't cut
        unset( $GLOBALS['TL_DCA']['tl_content']['list']['operations']['cut'] );

        // Non-admins can't delete
        unset( $GLOBALS['TL_DCA']['tl_content']['list']['operations']['delete'] );

        // Hides that Info icon for non-admins
        unset( $GLOBALS['TL_DCA']['tl_content']['list']['operations']['show'] );

        // Don't let non-admins create new content elements
        $GLOBALS['TL_DCA']['tl_content']['config']['closed'] = true;
}

Thanks for that bit o' code.

I'll have to see what the boss wants done for this. We have Writers, Editors, Publishers, and Admins... as far as I know, both Publishers and Admins will have rights to delete content, but others will not. Not sure if she will want to give Publishers admin rights however.

Maybe I can make an alternate backend template for these user groups to utilize and just remove instances of those buttons from the template?

Possibly -- but I'm not sure you could do that through a template, since everything is so dynamic.

A better strategy might be to check out, say, the news module and see how it checks for permissions. You just need to replace my "if" statement with whatever checks are necessary for user groups. It might be surprisingly straightforward.

It's something I have on my list of things to learn, but haven't gotten to it yet.
