When you want to alter a form on Drupal, it is useful to detect if the form being submitted is to add a new node or edit an existing node. To detect if a form is being added or submitted, check the
$form[<content-type>]['nid']['#value'].
Example :
$form['book']['nid']['#value'].
If the value is new, the node is being added.
If the value is numeric, the node with nid as the number is being edited.

Anyone got better ideas ?

To show similar content nodes on drupal you have to install the similar module. After installing the similar module

• goto admin/build/block
• Drag the Similar Entries module

OR

If you want to integrate the similar content to the node body, call the similar_content theme function.  print theme('similar_content', $node); on node.tpl.php

This was supposed to be obvious, but I couldnt find easily how to integrate Google Adsense and Analytics to track your Adsense Ad performance on google analytics. Make sure you display ads on your page and the analytics tracking code. Make sure you have linked the adsense and analytics together before doing this. The following is to add one more site to track adsense.

And then Getting straight to the answer, put the following script on the head.

<script type="Text/javascript">window.google_analytics_uacct = "UA-XXXXXX-X";</script>

If you use AddThis module on drupal, you might have noticed that a 1px by 1px flash object is created which sets tracking cookies on your pages. This is transparent to the user most time and you will see it only under generated source view. The flash button is added dynamically by the addThis module on the top of the page. This sometimes can be annoying since a white bar can appear at the top of the page due to this.

In drupal 6, the flash tracking can be disabled. In drupal 5 the tracking can be disabled by adding the following line of code to addthis.module
