How change group access of element depending of a variable value

[kouros91]

Hi.
I would like changing with php code form edit access group of an element depending of a value variable.
I would like too changing with php code "read only" value of a field element depending of a value variable.
How can i do to access to these properties ?
Thank you
Nicolas

That's not possible with the code as-is. I would have to add some additional code to the core, and provide a hook in the form PHP plugin, something like onElementCanUse, to allow custom code to be run to make decisions about per-element access control.

That's a couple of hours work to code and test.

Ok. For information, what is the price for two hours of work ? Thank you Hugh.

This is one of those things where to even answer your question, I had to flesh out some code, just to make sure it would work. So I'm already halfway there. I'll get Robbie to quote you on finishing it off.

Hi Hugh. I've paid last week for the code. How do i do to have access to the new properties ? Thanks . Nicolas

I committed that code a few days ago:

https://github.com/Fabrik/fabrik/commit/07fd7bfe0bb18269618e9e5f8ac6de349d896f7b

You'll need to do a full github update to pick up the changes.

To use it, you'll need to add a form PHP plugin, select 'onElementCanUse' as the hook, and then write a little code which return false if the element should not be editable.

In this example, I'm setting element ID 33 to read only if the 'event' join (fab_main_test___event_raw) is 17.

// probably don't want to do this for a new record, as elements won't have value, unless they are defaults
if (!$formModel->isNewRecord()) {
   // figure out which element we are being called for
  $elementId = $elementModel->getId();
   // is the element ID the one we want to hide?
  if ($elementId == 33) {
     // for debug purposes, uncomment the next line to see what the form data is set to
    //var_dump($elementId, $formModel->data);exit;
    // in this example, if the "event" join element is set to 17, we want to hide "this" element
    if ($formModel->data['fab_main_test___event_raw'] == '17') {
      return false;
    }
  }
}
return true;

In this example, if the 'event' is 18, I'm checking to see if the user is in Access Level 3 ("Special"), and sets read only (returns false) if they aren't;

// probably don't want to do this for a new record, as elements won't have value, unless they are defaults
if (!$formModel->isNewRecord()) {
   // figure out which element we are being called for
  $elementId = $elementModel->getId();
   // is the element ID the one we want to hide?
  if ($elementId == 33) {
     // for debug purposes, uncomment the next line to see what the form data is set to
    //var_dump($elementId, $formModel->data);exit;
    // in this example, if the "event" join element is set to 19, we want to hide "this" element
    // if the user isn't in the "Special" level (3)
    if ($formModel->data['fab_main_test___event_raw'] == '18') {
      $levels = $this->user->getAuthorisedViewLevels();
       // uncomment the next line for some debug output of the current user's access levels etc.
      //var_dump($levels, $this->user);exit;
      // will return false if user is not in Viewing Access level 3 ("Special")
      return in_array(3, $levels);
    }
  }
}
return true;

If you need help with the exact code you need, give me the full details of what you are trying to achieve.
