title: Drupal how to redirect node form after form submission
body: <p>On Drupal 7 when I post a node I redirect to the specific node created.</p>
  
  <p>I'm searching to redirect to the main admin page when I post correctly the node.</p>
  
  <p>I've tried to put this on template.php:</p>
  
  <pre><code>function node_submit($form, &amp;$form_state) {
    $form_state['redirect'] = 'admin';
  }
  </code></pre>
  
  <p>But there was an error on submit:</p>
  
  <blockquote>
    <p>Fatal error: Cannot redeclare node_submit() (previously declared in /var/www/XXX/modules/node/node.module:1004) in /var/www/XXX/sites/all/themes/XXX/template.php on line xx</p>
