Drupal 7 hook_node_view 将表单添加到节点的内容
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);
}
为什么表单不显示?难道我做错了什么?正在填充表单对象.我可以做#markup => 'Something' 并且它有效.
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
drupal_get_form 的返回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;
如果您确实想以其他方式执行此操作，尽管表单应该是可渲染的元素"，因此键不应以 # 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);
渲染数组中以 # 为前缀的键的所有条目都被视为属性，而不被视为子项"并递归渲染.
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.
