搜索框在Drupal中不起作用

Question

我剛剛在以下位置上傳了測試網站：www.betterclassofleaders.co.cc/whackk 我正在使用自定義搜索框（通過search-theme-form.tpl.php ）但它不起作用。如果您鍵入搜索字詞並按Enter鍵，則會轉到搜索結果頁面，但不會實際執行搜索。

通過搜索結果頁確實正常工作。任何想法可能是什麼問題？

顯然，您不能直接修改search-theme-form.tpl.php中的HTML，因爲那不是正確的方法。所以我添加類和onFocus和onBlur屬性是問題所在。

正確的做法是修改主題template.php文件。基本上我們將使用form_alter()來修改表單元素。由於使用HTML方式是錯誤的。看看下面的代碼（摘自：here）

<?php 
/** 
* Override or insert PHPTemplate variables into the search_theme_form template. 
* 
* @param $vars 
* A sequential array of variables to pass to the theme template. 
* @param $hook 
* The name of the theme function being called (not used in this case.) 
*/ 
function yourthemename_preprocess_search_theme_form(&$vars, $hook) { 
    // Note that in order to theme a search block you should rename this function 
    // to yourthemename_preprocess_search_block_form and use 
    // 'search_block_form' instead of 'search_theme_form' in the customizations 
    // bellow. 

    // Modify elements of the search form 
    $vars['form']['search_theme_form']['#title'] = t(''); 

    // Set a default value for the search box 
    $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', 
                   'onfocus' => "if (this.value == 'Search this Site') {this.value = '';}", 
                   'onblur' => "if (this.value == '') {this.value = 'Search this Site';}"); 

    // 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']); 
} 
?> 

在yourthemename_preprocess_search_theme_form - 「yourthemename」將明顯地反映出您的自定義主題的名稱。基本上，代碼是不言自明的。什麼與評論和所有。

所以，基本上這就是它的工作方式。
