 * Hey guys. I’m building my own theme for WordPress, and am still a bit new to 
   this so I need a bit of help 😀
 * I have a feature I built into the template that allows the user to email the 
   current page to a friend, it’s a plugin, and the way it works is collecting the
   User ID and sending them to another page like:
 * [http://domain.com/email/?id=5](http://domain.com/email/?id=5)
 * It works, but I want to have the same thing happening somewhere else on the template,
   hence I need to copy what the plugin does and put it in a new a tag if you know
   what i mean. Problem is the plugin uses PHP for everything and I can’t for the
   life of me see how it gets the post ID.
 * SO, if anyone knows how I can get the post id (not the permalink) for the current
   post I’d be extremely grateful 🙂
 * Cheers!

 * Most times it is `$post->ID` or might try `$id`.

 * I’m using WordPress 2.7.
 * I’m following the instructions [http://codex.wordpress.org/Template_Tags/wp_list_pages](http://codex.wordpress.org/Template_Tags/wp_list_pages)
 * but the $post->ID is returning a number that doesn’t work — actually a revision
   instead of the original post. THe original was id=33 (I checked the DB).
 * There was a revision ID=151 – and this is the number $post->ID gives me.
 * However, using wp_list_pages(“child_of” . $post->ID) doesn’t work. While it should
   return 151 because that is the last revision, WP doesn’t think that 151 has any
   child pages, because it doesn’t list anything.
 * What am I missing? I didn’t think it would be that hard to list sub pages.
