   Hello all,

   Is there any plugin available to execute set of php statements while creating a post ?

   my concern is, while submitting a post, the user will submit a URL as a custom field and couple of other custom fields. I need validate the URL submitted by user whether it is broken or not, then accept the post.

   let me know if there is any existing plugins available or show me a way how to do it.

   BTW, i know little bit of php & mysql ;)

   Make your own plugin. It's easy.

   Also see this:

   Look carefully at the action hooks, especially the "publish_post" action.

   thanks. I have tried quickly and now I would like to know some more info.

   a. I would like to find the post id of the post I am submitting to.
   b. I would like to find the custom fields submitted by user. (for the post I am trying to publish)

   I already tried get_post_custom_values("mycustomfield") but it doesn't work.

   Thanks a lot :)

   The publish_post action passes the ID of the post to your function.

   function whatever($postid) {
   // $postid has the post id in it.
   }
   add_action('publish_post','whatever');

   Then, you can use get_post_custom_values('whatever',$postid); as well.

   okay. it works great. thanks for helping me. :D

   Now i am facing a new problem. it executes the function every time we publish the post. I mean if we edit the same post it executes the function again.

   Is there any way to execute only once ?

   There's six different statuses for posts:
   publish
   draft
   private
   future
   pending
   new

   Whenever a post status changes, a OLD_to_NEW action occurs. So new_to_draft happens when you create a new draft, sort of thing.

   If you make five different hooks (all to your existing function), with all of the types going to_publish, then you can hook all the ways to publish a post for the first time. Like new_to_publish, pending_to_publish, etc.

   I can't find any documentation for the OLD_to_NEW posts—can you please point the way?

   Thanks.
