Album coding errors, simple PHP -

I am currently trying to develop the following functions:

Want to see or profile photo, I would like to use either album_id or id in the URL:

  album.php? Album_id = (numerical number) album.php? Id = (numerical number)   
 I am currently able to execute the first command and when I make another attempt, instead of loading it fails to index page (script According to the design).  
 Here's my code:  
  $ album_id = addlashes (is_numeric ($ HTTP_GET_VARS ["album_id"])); $ Profile_id = added zombies (is_numeric ($ HTTP_GET_VARS ["id"])); ? & Gt; & Lt ;? Php if ($ album_id == faucet ||! $ Profile_id == faucet) {Print ("& lt; script language = 'javascript' & gt; window = location = 'index.php';  ;);} Else {if ($ album_id == $ album_id) {included ("/ home / emo / public_html / incldues / layout / photos / pages / albums / album_photos.php");} Else {if ($ profile_id = = $ Profile_id) {include ("/ home / emo / public_html / incldues / layout / photos / pages / albums / profile_photos.php");} Else {include ("/ home / emo / public_html / incldues / layout / photos / Pages / album / album_photos.php ");}}}? & Gt;   
 And to make it clear, there is nothing in those" pages ", but bold saying:  Show album photos  and  users Show Photo   
 But what do I think my problem might be?   
 
 
 If you can call  album.php? Album_id = {id} ,  $ _GET ['id'] , your first  If  returns the statement index page.  
  if (($ album_id == null) || ($ profile_id == null)) {...}   
 An always  Null  as long as you  album.php? Album_id = {aid} and id = {pid}   
  (if $ Album_id == null) & amp; ($ Profile_id == zero)) Redirect to {# index.php} and {if ($ album_id! = Null) {# load album} else if ($ profile_id! = Null) {# Load profile} else {# both Gone, redirect to error}}
