块中的选项卡

Question

我想创建一个包含来自page.tpl.php的$ tabs的块

/**
 * Implements hook_block_info().
 */
function mymodule_block_info() {

  $blocks['tabs'] = array(
    'info' => t('Tabs in block'),
    'description' => t('blah blah blah'),
  );
  return $blocks;
}


/**
 * Implements hook_block_view().
 */
function mymodule_block_view($delta = '') {

  $block = array();

  switch ($delta) {

    case 'tabs':
      $block['subject'] = t("THIS IS ZHE TABS!");
      $block['content'] = array(
        '#theme' => 'menu_local_tasks',
        '#primary' => menu_local_tasks(0),
        '#secondary' => menu_local_tasks(1),
      );
    break;
  }
  return $block;
}

该块正在正确注册,并且正在显示正确的选项卡.但是,Drupal会抛出很多错误!

看来问题可能出在主题功能上。

我尝试使用这个并且它有效

$tabs =  menu_local_tasks(0);
$block['content'] =  $tabs['tabs']['output'];
