在 Drupal 中设置搜索框主题时遇到问题

Question

我不是世界上最有经验的 Drupal，并且在尝试自定义搜索框时我遇到了一场噩梦。我正在使用 Drupal 帮助站点上的示例，但它根本不起作用。

我已将 search-theme-form.tpl.php 从搜索模块复制到我的主题中，并复制了示例代码，该代码中预处理函数之外的任何 HTML 都显示正常，但据我所知，预处理-process 函数要么没有被调用，要么只是不影响我的搜索框。

我几乎可以肯定我错过了一些关于 Drupal 工作原理的绝对基本的东西，但我根本找不到任何信息。

这是代码：

 <?php 

function danland_preprocess_search_theme_form(&$vars, $hook) {
      // Remove the "Search this site" label from the form.


  $vars['form']['search_theme_form']['#title'] = t('');

  // Set a default value for text inside the search box field.
  $vars['form']['search_theme_form']['#value'] = t('Search this Site');

  // Add a custom class and placeholder text to the search box.
  $vars['form']['search_theme_form']['#attributes'] = array('class' => 'NormalTextBox txtSearch', 'onblur' => "if (this.value == '') {this.value = '".$vars['form']['search_theme_form']['#value']."';} ;", 'onfocus' => "if (this.value == '".$vars['form']['search_theme_form']['#value']."') {this.value = '';} ;" );


  // Change the text on the submit button
  //$vars['form']['submit']['#value'] = t('Go');

  // Rebuild the rendered version (search form only, rest remains unchanged)
  unset($vars['form']['search_theme_form']['#printed']);
  $vars['search']['search_theme_form'] = drupal_render($vars['form']['search_theme_form']);

  $vars['form']['submit']['#type'] = 'image_button';
  $vars['form']['submit']['#src'] = path_to_theme() . '/images/search.jpg';

  // Rebuild the rendered version (submit button, rest remains unchanged)
  unset($vars['form']['submit']['#printed']);
  $vars['search']['submit'] = drupal_render($vars['form']['submit']);

  // Collect all form elements to make it easier to print the whole form.
  $vars['search_form'] = implode($vars['search']);
}

?>


<div id="search" class="container-inline">
  <?php print $search_form; print $search_theme_form; ?>
</div>

将预处理函数放入主题目录中的 template.php 中，然后清除“admin/settings/performance”中的缓存
