Creating nodes using mini-forms anywhere

Recently a client needed to have a mini form for creating specific types of nodes on the fly from anywhere on the site. So, instead of the user clicking "Create content" then "foo" then filling in the form, then clicking submit, a form for that type of content will be shown on most pages in a block in the side bar. So, they can create that type of node quickly.

There are two ways to do this:

  • Call drupal_get_form('nodetype_node_form'), then use hook_form_alter() to unset the parts you don't need.
  • Create your own form, then do a drupal_execute() using the data from your form.

Calling the node type node form

For this, assuming you have a content type called foo, then you do the following:

function custom_foo_node_form() {
global $user;
$node = array(
'uid' => $user->uid,
'name' => $user->name,
'type' => 'foo',
);
return drupal_get_form('foo_node_form', $node);
}
function custom_form_alter($form_id, &$form) {
if ($form_id == 'foo_node_form') {
if ($_GET['q'] != 'node/add/foo') {
$values = array(
'menu',
'attachments',
'preview',
'options',
'author',
'log',
'body_filter',
'path',
);
foreach($values as $k) {
if (isset($form[$k])) {
unset($form[$k]);
}
}
}
}
} 

You then place the following in a block with type PHP or anywhere in the theme's .tpl.php you wish.

<?php print custom_foo_node_form() ?> 

Using your own form with drupal_execute()

However, in order to keep the mini form clean and not too busy, we opted for the second option.

For this, the code will look like this:

function custom_foo() {
return drupal_get_form('custom_foo_form');
}
function custom_foo_form() {
$form['title'] = array(
'#type'  => 'textfield',
'#title' => 'foo',
);
$form['taxonomy'] = taxonomy_form(1);
$form['submit'] = array(
'#type'  => 'submit',
'#value' => 'Foo',
);
return $form;
}
function custom_foo_form_submit($form_id, $form) {
global $user;
$form_id = 'foo_node_form';
$node = array(
'uid'  => $user->uid,
'name' => $user->name,
'type' => 'foo',
);
$form_values = array(
'title'    => $form['title'],
'name'     => $user->name,
'taxonomy' => $form['taxonomy'],
);
watchdog('debug', 'Saving foo from mini node form');
drupal_execute($form_id, $form_values, $node);
} 

Note that there is no body for this type of node, as it is a CCK type with an optional body. Only the title is relevant. But of course you can include a body if you so wish.

Then, in a block of type PHP or anywhere in your tpl.php files, you place the following call:

<?php print custom_foo() ?>

There is also shortform module

If the core set of fields is basically the same this is a great way of shortening them so that the form can be displayed in the sidebar:
http://drupal.org/project/shortform

Alternatively you can just use it as a helper function in your theme - i.e. unset the fields you want, and then pass the result through shortform.

Very nice

Excellent!

How big a step is this (and programmatic creation of nodes) toward inline creation of nodes (say I'm creating a user profile node and I can create my organization profile node at the same time if it doesn't exist already)?

And it seems to get Drupal closer to my other dream: registering (or logging into) a site simultaneous with posting content for the first time...

Here's hoping, though of course this is good in itself.

Thank you for this

Thank you for this article!
Seems in second way taxonomy select doesn't work properly - always submits first term from dropdown list. How can I fix it?

Taxonomy

Yeah the taxonomy part doesn't seem to be working on the part 2 thing also when doing stuff with CCK you need to have this for the fields:

$form_values['field_foo'][0]['value'] = $form['fraga'];

can not save the taxonomy

can not save the taxonomy term which be selected when submit the form, any tips should be thankful

/** add article node/add form **/
function modulename_article() {
return drupal_get_form('modulename_article_form');
}

function modulename_article_form() {
$form['title'] = array(
'#type' => 'textfield',
'#title' => 'article',
'#size' => 30,
);

$form['body'] = array(
'#type' => 'textarea',
'#title' => 'body',
'#size' => 30,
);

$form['taxonomy'] = taxonomy_form(6);

$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Post',
);

return $form;
}

function modulename_article_form_submit($form_id, $form) {
global $user;

$form_state = array();
module_load_include('inc', 'node', 'node.pages');

$node = array('type' => 'article');

$form_state['values']['taxonomy'] = $form['values']['taxonomy'][1];

$form_state['values']['title'] = $form['values']['title'];
$form_state['values']['body'] = $form['values']['body'];
$form_state['values']['name'] = $user->name;
$form_state['values']['op'] = t('Save');

drupal_execute('article_node_form', $form_state, (object)$node);
}

<?php
   
print modulename_article();
?>

free tagging code

great snippets. I tried the free tagging, but don't know the exact code for that. Any help would be appreciated. Thanks.

Also for normal nodes (not cck)

Hi,

Is this snippet also to be used with links_weblink (weblinks-node)?
It would be great to be able to add nodes on taxonomy screen level.

Please respond, or may be the code to use this snippet for the weblinks-node?

Thanks in advance!

greetings,
Martijn

This isn't very elegant. You can alter a form without implemeneting hook_form_alter and without resorting to some magic URL. Simply do:

$form = drupal_retrieve_form('foo_node_form', $node);
// ... manipulate $form ...
drupal_process_form('foo_node_form', $form);
return drupal_render_form('foo_node_form', $form);

I mentioned this technique in a forum post, and I also demonstrated it in some article.

Kindness is for free...

...however you are right, your solution is much more elegant.
Thank you for posting.

function custom_form_alter

I am using Drupal 5.9 and a php newbie. I am using the first example (Calling the node type node form)to add a form in a mini panel on a profile page and no matter what I do, I can't get No matter what I do I can't form_alter function to remove the
'comment_settings',
'menu',
'attachments',
'preview',
'options',
'author',
'log',
'body_filter',
'path'
from the form.

everything else works great, I would just like to hide all of those settings.

erorr

 

to me it returns

warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'foo_node_form' was given in Z:\home\wecook.lc\www\includes\form.inc on line 366.

 

what do i do wrong ? using the second way

the code above only works for

the code above only works for drupal 5.x - in 6.x there were some changes in form api... i am trying to figure it out myself at the moment, so i can't provide a solution. perhaps the author can?

This is a great tutorial. I

This is a great tutorial. I was able to implement this and put the form on the left side bar of the site. However, I noticed that my autocomplete fields in the new forms were no longer working. Do you know of a quick fix to this? Looking forward to hearing back, thanks.

drupal_execute()

Has been renamed to drupal_form_submit() in D7.

Thanks for the guide.

Where should I place function?

Could you please advise where is the function to be placed? I saved it in template.php, but then it says Fatal error: Call to undefined function and the function isn't found. Shall place it in page.tpl.php directly instead?
