I'm lost. What are you trying to do?

I'm not quite sure what you're trying to do either, but my guess is
that you want to assign something to $page, right?

so...

PHP:

<?php

if( !isset( $_GET['page'] ) || empty( $_GET['id'] ))
{
  $page = "home.html";  // changed something here
}
 else 
 if(preg_match("/html/", $page)){
  $page = $page.'.html';  // changed something here
  }
  elseif(preg_match("/php/", $page)){
 $page = $page.'.php'; // changed something here
  }

?>

nope it wont change now

Maybe the last elseif should be an else?

why bother with preg_match ?
From sabrina's code

PHP:

<?php

if( !isset( $_GET['page'] ) || empty( $_GET['id'] ))

{

  $page = "home.html";  // changed something here

}

 else 

 if(strpos( $page, 'html')!==false){

  $page = $page.'.html';  // changed something here

  }

  elseif(strpos( $page, 'php')!==false){

 $page = $page.'.php'; // changed something here

  }

?>

But just out of curiosity? Where is $page coming from? Try maybe $_GET['page'] since i get a feeling $page is meant to be using register globals, which most production servers will have disabled.

Also, the way you're doing it, i'm assuming you're looking for $page to having something like idiot.html or idiot.php .. but the way you're doing it you'll end up with idiot.html.html or idiot.php.php ....

no i own the server lets say if u wanted to goto contacts page u would go www.yoursite.com/index.php?page=contacts

but if i wanted to just goto www.yoursite.com/ it will display the home page the reason for all this trouble is so i can have this bit after the code

[PHP]<iframe src="<?php echo $page; ?>" name="_text" width="737" height="100%" frameborder="0" scrolling="yes"></iframe>[PHP]

Errr.. okay.. so does your site use .html or .php driven pages?

Because either way, the method you're using wont work since you're looking for 'html' or 'php' in either, and neither will be found since your $_GET['page'] will just be 'contacts' .. do you follow?

should this

PHP:

<?php
if( !isset( $_GET['page'] ) || empty( $_GET['id'] ))
?>

be this

PHP:

<?php
if( !isset( $_GET['page'] ) || empty( $_GET['page'] ))
?>

?

Wouldn't using switch statements be easier?
