Extend viewdefs to change a value for a button

Artis Plocins

I am trying to disable a button in the Save button dropdown in a module's record view.

I would like to do that for just that single button without overriding the entire file, so I thought I would create and extension file for the record view and unset that array element.

Obviously if there are other extensions adding more buttons in this dropdown, I don't want to unset the wrong one, so I tried all kinds of foreach loops with if statements, array_walk_recursive(), array_map() and more foreach loops referencing the original array.

The only actual way I managed to do it is still this:

unset($viewdefs['Calls']['base']['view']['record']['buttons'][1]['buttons'][1]);

And if another button gets added at the top of the dropdown, this should theoretically remove the wrong button!

I cannot find anything in the documentation or examples of how this simple thing should be done besides copying the entire file. I believe that would make this simple change affect any other modules also trying to affect the same view.

    Hi Artis Plocins 

    I believe this article is useful.

    Good luck!

    Hi, thanks but I've seen that page already and it only explains how to add something in viewdefs, not remove an element from it or change a single property of an element like a button type. Is there really no way to do that other than fully overriding the entire record.php file?

    You may remove elements as well. You just have to walk through all buttons in order to make sure you will remove the correct one. Inside this walkthrough you need to look for a specific button attribute in order to identify the target one.

    We had done that previously without big deal.

    Good luck!

    Can you please check and see why this bit of code does not do anything like I think it should?

    This is the first thing I tried, and I tried again and it still doesn't work.

    In the file custom/Extension/modules/Calls/Ext/clients/base/views/record/record.php

    <?php

    foreach ($viewdefs['Calls']['base']['view']['record']['buttons'] as &$button) {
      if ($button['name'] == 'save_dropdown') {
        foreach ($button['buttons'] as &$btn) {
          if ($btn['name'] == 'save_invite_button') {
            unset($btn);
          }
        }
      }
    }

    After rebuilding and clearing the cache, the button is still there:

    Although this should also work, in theory, but doesn't:

    function remove_button(&$item) {
        if ($item['name'] == 'save_invite_button') {
            unset($item);
        }
    }

    array_walk_recursive($viewdefs['Calls']['base']['view']['record']['buttons'], 'remove_button');
