include() issue

[Plug-in]

Hey if you could help me I would really appreciate it, I haven't been coding for a while and I'm getting stuck on quite a basic part of my script, in fact it was the first part.

 

I'm using the include(); function to include a file which will be used to show multiple pages through the $_GET variable, for example if you don't understand what I'm talking about if I was making an "about" page I might do index.php?page=about and it would retrieve the "about" page. Unfortunately I keep getting this error:

 

Warning: include(back_func.php?id=new) [function.include]: failed to open stream: No error in C:\Program Files\EasyPHP-5.3.9\www\link_extension\index.php on line 25

 

Warning: include() [function.include]: Failed opening 'back_func.php?id=new' for inclusion (include_path='.;C:\php\pear') in C:\Program Files\EasyPHP-5.3.9\www\link_extension\index.php on line 25

 

Notice: Undefined variable: var in C:\Program Files\EasyPHP-5.3.9\www\link_extension\index.php on line 26

 

This is the PHP in my index page, notice it consists of one line because I removed the rest for testing:

include('back_func.php?id=new');
      echo $var;

This is my back_func.php page, also simplified for testing:

<?php
if (isset($_GET['id']))
$var = 'worked';
else
$var = 'not';
?>

 

If you don't understand what I'm asking but feel you could help I'm happy to further explain, I'm expecting it's something basic I've forgotten.

Thanks.

PHP include function basically includes the file data BEFORE process, so passing a parameter will not work

 

try just including back_func.php

Thanks, I redesigned my idea around what you said.

you should use almost always use require_once unless you need the file to be used more than once on a page.

Thanks, I usually do but it was just drafting the code to make sure I could get it to work, and I couldn't but fortunately I've fixed it up
