override tabs 覆写tabs的方法

here is a very easy solution for you. (Drupal 7)

• Open your page.tpl.php in your current template and search for the $tabs variable.

• Remove the render code if you want to hide it completely.

• If you want to display it only to administrators use this code

  <?php if ($tabs and $is_admin): ?>
  <div class="tabs">
    <?php print render($tabs); ?>
  </div>

  The above code checks if the user is administrator. If it is it will render the tabs. If not it wont render them.

On the module side, you could do something that decouples the Edit's menu entry from the local tasks for the node:

function custom_menu_alter(&$items) {
  $items['node/%node/edit']['type'] = MENU_CALLBACK;
}

The edit path is still there, but now it is not associated with the View tab. This includes the edit page itself--no View tab there.

there is a module for that: tab tamer allows to hide or disable tabs and rename them as well.

I use the following in template.php by theme (which is perhaps a little hacky, I feel I should be considering unsetting $tabs instead):

function THEME_NAME_menu_local_tasks() {
  return '';
}

Or you could ommit:

if ($tabs) echo $tabs;

from your page.tpl.php...

View and Edit are functional features. They have a reason for being there.

The best way to "remove" them, is to "remove" that functionality alltogether. After all: why remove the interface of a piece of functionality, but not the functionality itself? Besides, simply not printing the tabs, does not remove the url endpoints. In other words: if you don't print the edit tab, people can still access the edit page.

Again: best is to remove that functionality: The fact that you don't want the edit tab, sounds as if you don't want the edit functionality for certain users. If so, then just remove that permission for that role. That is all. The tabs will be gone.

If, however, you simply wish to display these tabs differently, Drupal is your friends. As you may have noticed, they are called local tasks and not tabs. That is because the theme decides how to render them: The theme is the thing that decides to show them as tabs.

Simply override the theme_menu_local_tasks() to create your own HTML for the "local-tasks". And in your page-tpl, simply move the $tabs variable around to a place, where you want them.

But again: Don't try to change the behavior of the app, by removing interface-elements. That is not the right thing to do: you should change the behavior, in order to change the behavior :)

This is not the answer to the question of what the author asked. But somehow it might be useful for others user who facing the similar problem with me. Please let me know if this is not suitable to put in here.

I get the answer from @grayside and modified a bit to hide the view | edit tab from node based on the content type I want.

    function MYMODULE_menu_alter(&$items) { 
      $items['node/%node/view']['access callback'] = 'MYMODULE_disable_node_view';
      $items['node/%node/view']['access arguments'] = array(1); 
    } 

    function MYMODULE_disable_node_view($node){
      if($node->type == 'product'){
        return false;
      }
    }

product is the machine name of my content type, I don't want anywant to access it including root user.
