drupal 7 hook_node_view将一个表单添加到节点的内容 [英] Drupal 7 hook_node_view add a form to the content of a node

问题描述

function example_module_node_view($node, $view_mode, $langcode)
{   
    $f =  drupal_get_form('example_module_form', $node);
    $node->content['data_collection_form'] = array('#value' => $f, '#weight' => 1); 
}

为什么窗体不显示？我做错了吗？正在填充表单对象。我可以做#markup =>'Something'，它的作品。

Why doesn't the form display? Am I doing something wrong? The form object is being populated. I can do #markup => 'Something' and it works.

推荐答案

从 drupal_get_form 实际上是一个渲染数组本身，所以你可以这样做：

The return from drupal_get_form is actually a render array itself so you could just do this:

$f = drupal_get_form('example_module_form', $node);
$f['#weight'] = 1;
$node->content['data_collection_form'] = $f;

如果你想做另一种方式，虽然表单应该是可渲染的元素所以关键不应该以＃为前缀：

If you do want to do it the other way though the form should be a renderable 'element', so the key shouldn't be prefixed by #:

$f = drupal_get_form('example_module_form', $node);
$node->content['data_collection_form'] = array(0 => $f, '#weight' => 1);

具有前缀为＃被认为是属性，而那些不被认为是孩子并被递归呈现。

All entries in a render array with a key prefixed with # are considered properties, while those that aren't are considered 'children' and are recursively rendered.
