[solved] Conditionally limiting editing of page based on page properties and role

Recommended Posts

I need to restrict editing access based on both the user role, and the value of a sub-field in a page reference field.

eg $page->competition->closingDate 

There's some discussion about restricting editing access based on role, and that works, but when I try to access the page via the method @Robin S suggests, the page returned is an admin page rather than the page being edited, so I don't have access to the edited page's fields.

I think you'll want to hook Page::editable in /site/init.php and set the event return to false if the user should not be able to edit the page.

That works perfectly. It saved me a heap of time trying to figure out what hook to use.

      Hi,
      is there a hook after the current (active) page got created? Or which method got called in the Page class after the Constructor of the current page got initialized?
      Thanks.

      Continuing my journey into PW hooks, I'm trying to find a way to retrieve all images from a page that explicitly *do not* have a certain tag (or tags) attached to them.
      Found this post from 2015
      But I'm wondering if there's a more elegant way to go about this.
      Let's say I have a multi-image field called "images_header" and instead of
      $page->images_header->findTag('mytag'); I would like to do this:
      $page->images_header->excludeTag('mytag'); So I'd be able to do
      // find images that don't have the tag "mytag" $images = $page->images_header->excludeTag('mytag'); // check if there's any images if (count($images)>0) { // do something.. } Would this be possible by hooking into Pagefiles somehow?
      There's this bit in /wire/core/Pagefiles.php Line 626 that I'd basically just need to reverse (or at least in my mind 😄 )
      public function findTag($tag) { $items = $this->makeNew(); foreach($this as $pagefile) { if($pagefile->hasTag($tag)) $items->add($pagefile); } return $items; } Any ideas on how this could be done in a graceful manner?
      Thanks in advance!

      Getting a little deeper into the ProcessWire state-of-mind here. I seriously think I wouldn't have come back to webdev if it wasn't for this wonderful little gem of a CMS.
      I have an "Options" field added to all users on a site. If the user has anything other then "default" selected, I would like to show a permanent message in the admin like the one in the screenshot, only so that the user can't close it. As a friendly reminder that he changed that option from default to something crazy 🙂
      I've read up on how to send messages to users, but where would I hook into to make this show up all the time in the backend?

      Thanks in advance!

      Hello,
       
      Here's what I'm trying to achieve : I have a textarea field that is frontend editable on any page I want to. If a user with a specific role updates it, I want to tick a checkbox field on the parent page where the textarea resides. So I tried to hook as follows in my ready.php file :

        $this->addHookBefore('Fieldtype::savePageField', function(HookEvent $event) {       $page = $event->argument[0];       $field = $event->argument[1];       if($this->user->hasRole('teacher')) {      $page->alertBox = 1;       } // DEBUG HERE (bd($page),  l($field)... ????   }); Of course (!) it doesn't work (yet !) but the thing is I have no idea how to debug this since my bd() never triggers. I've tried the 'Event interceptor' of Tracy debugger which helped me setting up my hook. I guess my $page and $field are correct... but how could I go any further ?
      The road is long to become a dev (when you're not one 🙂 )...
      For further information in case someone wonders : I'd like to set up a textarea that is modified by a user (having a 'player' role, ie 'student'). When front-end modified, I wish it would automatically alert me (the teacher) by ticking a box. So when I log in with my teacher role, I get a list of all textareas I have to read over. When I read/correct/update them (front-end), I would like my hook to automatically untick the box to remove it from my list. In other words, the 'textarea' status should go back and forth according to who modified it last. For the time being, I have managed to make it work with a checkbox that the user has to manually tick/untick, but I've noticed many kids forget to tick the box so they edit their text and I don't get a notice 😞
      Thanks if anyone takes time to try and help me on that one !
