Check if a view is enabled or disabled

Question

How can I check from a custom module if a specific view is enabled or disabled?

Answer 1

Having a view object, checking if the view is disabled just requires to check the value of $view->disabled; if it is TRUE, the view is disabled.

if (!$view->disabled) {
  // The view is enabled.
}

This method works independently from the view type, and it doesn't give false negatives when a module alters the output returned from a hook implemented by another module, which is what could happen with hook_block_view(), whose output could be altered by hook_block_view_alter().

To get a view object, you can use views_get_view($name), which is the function used also from views_block_view().

if ($view = views_get_view($name)) {
  if ($view->access($display_id)) {
    $view->set_display($display_id);
    if (isset($view->display_handler)) {
      $output = $view->display_handler->view_special_blocks($type);
      // Before returning the block output, convert it to a renderable
      // array with contextual links.
      views_add_block_contextual_links($output, $view, $display_id, 'special_block_' . $type);
      $view->destroy();
      return $output;
    }
  }
  $view->destroy();
}

If you also need to know if the currently logged-in user has access to the view (i.e. the user can see the view output), you need also to call $view->access($display_id), where $display_id can be easily get from the delta of the block with list($nothing, $type, $name, $display_id) = explode('-', $delta);.

The code you need to use, in the case of just checking if the view is enabled is similar to the following.

$view = views_get_view($name);
// Always check the value returned from views_get_view(), since it can return NULL.
if (!empty($view) && $view->disabled) {
  // The view exists and it is enabled.
}

In the case you need to check the currently logged-in user has access to the view, the code should be similar to the following one.

$view = views_get_view($name);
// Always check the value returned from views_get_view(), since it can return NULL.
if (!empty($view) && $view->access($display_id)) {
  // The view exists and the user has access to it.
}

Answer 2

I did it with module_invoke().

$block = module_invoke('views','block_view','-exp-machinenameoftheview-page');
if (!empty($block)) {
  // The view is enabled.
}
else{
  // The view is disabled.
}

You can use the views_get_view function to do this.

$view = views_get_view('view_name');
if ($view->disabled) {
  // Do something
}
