Drupal:在高级搜索中重新选择分类术语

创建一个模块并使用hook\u form\u alter()修改表单。我已经有了一个用于定制高级搜索的模块,所以我把它放在那里。我不会详细介绍构建您自己的模块——您可以找到一个简单的教程,您只需要定义这一个函数。

/**
 * Implementation of hook_form_alter().
 * Remove 'category:x,y,z' from the keyword textbox and select them in the taxonomy terms list
 */
function modulename_form_alter(&$form, $form_state, $form_id) {
    // Advanced node search form
    if ($form_id == 'search_form' && $form['module']['#value'] == 'node' && user_access('use advanced search')) {
        // Remove category:x,y,z from the keyword box
        $searchPhrase = $form['basic']['inline']['keys']['#default_value'];
        if(!empty($searchPhrase) && strpos($searchPhrase, 'category:') !== false) {
            $searchWords = explode(' ', $form['basic']['inline']['keys']['#default_value']);
            foreach($searchWords as $index=>$word) {
                if(strpos($word, 'category:') === 0) {
                    // Use the value to set the default on the taxonomy search
                    $word = substr($word, strlen('category:'));
                    $form['advanced']['category']['#default_value'] = explode(',', $word);
                    // Remove it from the keyword textbox
                    unset($searchWords[$index]);
                }
            }

            // Re-set the default value for the text box without the category: part
            $form['basic']['inline']['keys']['#default_value'] = implode(' ', $searchWords);
        }
    }
}

上面的解决方案确实从关键字搜索字段中删除了“category:0,0,0,0,0,…,0”字符串,并正确检查了所有分类术语。对于内容类型也可以这样做,您只需在整个脚本中将“category:”替换为“type:”。
