在Drupal中搜索框出现问题

问题描述：

我不是世界上经验最丰富的Drupal，我有一个恶梦试图自定义搜索框。我使用Drupal帮助网站的示例，它根本无法工作。在Drupal中搜索框出现问题

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，该代码中的任何HTML都在预处理函数之外显示出良好但尽可能我可以告诉，预处理功能要么不被调用，要么不影响我的搜索框。

我几乎可以肯定，我错过了一些关于Drupal如何工作的绝对基本的基础知识，但是我根本找不到任何信息。

下面的代码：

<?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>

把预处理功能template.php在你的主题目录，然后清除缓存在“管理/设置/业绩”

下面是一些有用的链接了解主题化与模板/预处理功能：
