How to give a content editor access to the theme settings?

Question

I'm using the Marinelli theme and want to give my main content editor access to the theme settings. Ideally just the ability to upload/change/add/subtract/enable the backgrounds of the rotating banner.

I don't see any way for them to do this without full access to the Theme settings. I was able to just give "administer themes" settings to this user and give them a shortcut to that theme. But that's still a lot of liability.

Has anyone been able to do this: limit theme configuration to just certain tasks?

You could use a hook_form_alter in your custom module.

The following assumes you already have a role called editor existing in your website.

1. Create a mymodule folder (e.g. in http://www.example.com/sites/all/modules/custom/mymodule)
2. Create two files in that folder. mymodule.module and mymodule.info

3. Past the following code in mymodule.module

    <?php
   
     function mymodule_form_alter(&$form, &$form_state, $form_id) {
     global $user;
   
     if ($form_id == 'system_theme_settings' && in_array('editor', array_values($user->roles))) {
       // unset the elements you don't want your content editor to have access to
       // unset($form['css3']);
       // Here we want to hide some form elements.
       // To hide/show an element we must use $element['#access'] key in the render array.
       // Using unset($element) might cause issues in form_validate and form_submit processes.
       // So instead of unset($form['css3'], $form['layout']) we set their access to FALSE
       $form['css3']['#access'] = false;
       $form['layout']['#access'] = false;
     }
   }
   

4. Past the following in mymodule.info

   name = Mymodule
   core = 7.x

5. Enable your module at http://www.example.com/admin/modules

6. Clear your cache
