如何在Drupal 7中修改$ content数据？

我想更改/修改模块的块内容：博客

我尝试了我的template.php文件：

function blog_block_view($delta = '') {
   return "Test, yes i am here";
}

但没有任何反应......

Answer 1

要更改现有广告资源的$内容，您需要create a custom module，hook_block_view_alter（）实施。

Drupal.org示例：

function hook_block_view_alter(&$data, $block) {
  // Remove the contextual links on all blocks that provide them.
  if (is_array($data['content']) && isset($data['content']['#contextual_links'])) {
    unset($data['content']['#contextual_links']);
  }
  // Add a theme wrapper function defined by the current module to all blocks
  // provided by the "somemodule" module.
  if (is_array($data['content']) && $block->module == 'somemodule') {
    $data['content']['#theme_wrappers'][] = 'mymodule_special_block';
  }
}

Answer 2

根据以下示例，您可以在.module文件中进行修改。

function hook_block_view($delta = '') {
  // All of these are functionally identical.
  $block['subject'] = '';
  $block['subject'] = NULL; // Or just don't set.
  $block['title'] = '<none>'; // Undocumented, but works.
  // This will not behave as desired.
  $block['subject'] = '<none>';
  $block['content'] = array(
        '#theme' => 'feed_icon',
        '#url' => 'rss.xml',
        '#title' => t('Syndicate'),
      );
return $block; 
}

Answer 3

这是正确的格式。

确保检查增量是否正确，否则您可能会更改比您的意图更多的块。

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

  if ($delta == "mydelta"){
    $block['subject'] = 'The Greatest Block Ever Created';
    $block['content'] = array(
      '#markup' => "<h1>Here's some content</h1>",
    );
  }

  return $block;
}
