              unset($form[$key]);    
 }
$variables['contact']=drupal_render_children($form);
}
?>

问题是当我试图渲染template_preprocess_contact_theme_form中的每个元素时，我删除了这个函数，一切似乎都在起作用。有人可以帮我解决这个问题吗？

Answer 1

您的<form>标签出现了吗？在表单主题中，您可能需要呈现表单子项，然后使用theme_form()。

$buildform = '&lt;div&gt;'.drupal_render($form['elem1']).'&lt;/div&gt;';
$buildform .= drupal_render($form['elem2']);
$buildform .= drupal_render($form['form_build_id']);
$buildform .= drupal_render($form['form_id']);
$form['element']['#children'] = $buildform;
$output = theme_form($form);

Answer 2

解决它。我的template_preprocess_contact_theme_form我删除了form_build_id，form_id这是错误的，而不是隐藏，我正在删除值。

Ajax在drupal 7.x中的自定义主题中不起作用
