In Drupal 7, I have a preprocess function retrieving a form like so:

$contact = drupal_get_form('privatemsg_new');

$contact is then a fully populated form array with the right fields and elements. After that, I tried drupal_render and render, but neither one show a themed output in the node. What do I have to do to display the form?

The correct answer is to use drupal_render, which is used for render arrays like the form is. I tested this with a different form, and got the desired result so what you're doing should be right. Most likely you have a different error some where in your code causing this.

$html = drupal_render(drupal_get_form('form_id', $args)));
  • Doh! I just realized I am in a preprocess function, so it should have been $vars['contact'] with the render. Thanks for helping. – Kevin Jul 29 '11 at 17:30
  • if use above method, 'form' tag is not rendered – Guru Jul 22 '15 at 12:14
  • @Guru If the form tag is not rendered, then you have a different issue. I've done this many times and it have worked fine every time. – googletorp Jul 23 '15 at 12:26
  • Thanks @googletorp it is working fine. I've also faced another problem. ie, '#ajax' is not triggered when i rendered form by above method. Is any other solutions for this? – Guru Jul 28 '15 at 4:44
