Programmatically a create content form

Question

I want to implement the create content form programmatically. In hook_menu() I have the following code.

$items['create/content/video'] = array(
  'title' => 'Create Video',
  'page callback' => 'create_content_video',
  'access arguments' => array('create video'),
  'type' => MENU_LOCAL_TASK,
  'weight' => 1
);

In hook_init(), I have the following code.

if (arg(0)=='node' && arg(1)=='add') {
  drupal_goto('create/content/'.arg(2));
}

In hook_theme(), I have the following code.

'video_node_form' => array(
  'arguments' => array(
    'form' => NULL,
  ),
  'template' => 'my_theme_video_form',
  'render element' => 'form',
),

In the page callback, I have the following code.

function create_content_video() {
  module_load_include('inc', 'node', 'node.pages');
  return node_add('video');
}

In the template file, I render form element correctly. My problem is with the the AJAX uploader in the form. Without, I use the upload button to upload the file, and the node is correctly saved; when I use the AJAX uploader, it returns an error.

When I create content without this method, it works fine.
I am using Drupal 7.14.

I agree with Clive, that this seems like a great deal of trouble, but what you should be doing generally, is calling field_attach_form(), and more specifically for nodes, node_form(), which calls the former. The arguments it expects are

You can see an example on the first here: Is displaying a working Field Widget Form on its own possible?

If you are just trying to theme the edit form for the "video" content type, then you can simply use the following code.

function mymodule_form_video_node_form_alter(&$form, &$form_state) {
  $form['#theme'] = 'mymodule_video_form';
}

Your hook_theme() implementation needs to be changed, as:

• arguments is a property that is not used in Drupal 7; you should use variables.
• As reported in the documentation, "each information array must contain either a 'variables' element or a 'render element' element, but not both."

If you are implementing that code just to be able to use create/content/video, instead of node/add/video, then I would suggest not to implement such code.
From the code you are showing, I see there is something wrong: You define a callback for create/content/video, but your hook_init() implementation is redirecting the users also for other content types, as it is not checking the value of arg(2).

As per this post, if you've a file upload widget, you should add the following lines th the menu array ($items):

'file path' => drupal_get_path('module', 'node'),
'file' => 'node.pages.inc',
