Adding extra button on node edit form with save functionality enabled

Question

I want to add an extra button on the node/edit drupal 7 form. That can be done by hooking into the form_alter:

$form['actions']['push'] = array(
 '#type' => 'submit',
 '#value' => t('Save && Push'),
 '#callback' => 'my_callback',
);

In my callback I want to run my custom Push function and save the node.

Any ideas how to achieve this?

function my_callback_action(&$form, &$form_state) {
  dpm('my_callback_action');
  return '';
}

You need to add your own extra submit function to your form. The big question is - where is default one?

If default function is attached to form itself, all you need to do is:

$form['#submit'][] = 'my_callback';

Then in callback test if it was your button that triggered it.

If it's attached to button, you need to copy original button's submit array to your button, and attach your callback:

$form['yourbutton']['#submit'] =  $form['originalbutton']['#submit'];
$form['yourbutton']['#submit'][] ='my_callback';

If it's attached to form, but you want yours attached to button, the way is of course:

$form['yourbutton']['#submit'] = $form['#submit'];
$form['yourbutton']['#submit'][] = 'my_callback';

There is a Drupal module called Content Type Extras that make it easy to add another "Save" button at the top of an edit page. It also includes other extra buttons, such as a "Save and New" button and a "Save and Edit" button.

This module provides some additional features and the ability to set default settings for content type options, such as 'Promoted to front page', 'Display author and date information', etc.
