[Drupal] Submit and redirect back to the modify page

First you have to create a new module called "my_submit", and in the my_submit.module, insert the code as below:

代码

<?php
// $Id:

/********************************   READ ME     **********************
*
*
No addons required. Drop the entire submit again folder in your modules directory,
usually sites/all/modules on your Drupal filesystem, activate it on the modules
page, and turn it on for each content type it should be attached to at

Administer -> Content management -> Content types -> (edit each content type)
*

/**
* @file
* Add a new button to node creation forms that
* allows the content author to return to the node
* creation form after saving new content instead
* of going to the view page of the new content.
*/

/**
* Implementation of hook_form_alter().
*/
function my_submit_form_alter(&$form, $form_state, $form_id) {
if (strpos($form_id, '_node_form') && !isset($form['nid']['#value'])) {
if (variable_get('my_submit_'. $form['type']['#value'], FALSE)) {
$form['buttons']['my_submit'] = array(
'#type' => 'submit',
'#value' => t('Save and review'),
'#weight' => 41,
'#submit' => array('node_form_submit', 'my_submit_node_form_submit'),
);
}
}
}

function my_submit_node_form_submit($form, &$form_state) {
//Go back to the content edit page which is created just now.
$form_state['redirect'] .= '/edit';
}

/**
* Alter content type settings to add "Submit Again?" checkbox
*/
function my_submit_form_node_type_form_alter(&$form, &$form_state) {
if (isset($form['identity']['type'])) {
$form['submission']['my_submit'] = array(
'#type' => 'checkbox',
'#title' => t('Submit and review?'),
'#default_value' => variable_get('my_submit_'. $form['#node_type']->type, FALSE),
'#description' => t('Enable this checkbox if you want to provide a "Save and review" button for your users.')
);
}
}
