Url's with php. HELP!

[dragonfly_7456]

Did you try to remove the slash as i suggested in post #46?

-Helge

That did nothing. I've got a good idea. How about you post your exact coding for your test, and I'll see if it works, ok? That could work better, cause if your example doesn't work on my server, then it's obviously not the coding that is wrong, right? Please post your example's coding.

[Helge]

Ok.

index.php

<?php // index.php
error_reporting(E_ALL);
echo '<h1>This is index.php</h1>';
echo '<p>The page variable coming from the url is: ' . $_GET['page'] . '.</p>';

switch ($_GET['page']) {  
    case 'add': 
        include ('add.php'); 
    break; 
    case 'downloads': 
        include ('downloads.php'); 
    break; 
    default: 
        include ('default.php'); 
    break; 
} 
?>

add.php

<h1>Yep!! add.php got included</h1>

What about the default page?

[dragonfly_7456]

Using your example, here is what I got:

This is index.php


Warning: Undefined variable: _GET in c:\apache\www\test\index.php on line 4
The page variable coming from the url is: .

Warning: Undefined variable: _GET in c:\apache\www\test\index.php on line 6
Hello

[Helge]

The warnings is coming because of the error level that is set on top of index.php. I always develop with that set to highest.

Ok, I've changed something in index.php

index.php

<?php // index.php
error_reporting(E_ALL);
echo '<h1>This is index.php</h1>';

$self = $_SERVER['PHP_SELF'];
echo "<a href=\"$self\">index</a> | <a href=\"$self?page=add\">add</a>| <a href=\"$self?page=wrong\">errorpage</a>";

$_GET['page'] = (empty($_GET['page'])) ? 'default' : $_GET['page'];

echo '<p>The page variable is: ' . $_GET['page'] . '.</p>';

switch ($_GET['page']) {  
    case 'add': 
        include ('add.php'); 
    break; 
    case 'downloads': 
        include ('downloads.php'); 
    break; 
    default: 
        include ('default.php'); 
    break; 
} 
?>

default.php

<h1>This is the default.php</h1>

You can go see your example on my site for yourself:

[dragonfly_7456]

AAAAA!!!!! I'm so confused!!! Is your example online?

Here is what my test page is showing:

This is index.php


Warning: Undefined variable: _SERVER in c:\apache\www\test\index.php on line 5
</FONT>index | add| errorpage The page variable is: default.
This is the default.php


How come I am getting the undefined variable, while you are not?

[Helge]

I did see that.
And why that is happening is beyond my knowledge. I've never installed/administrated a server so I don't know.

I've highlighted the $self variable in my page. As you can see it works there.

I'm sorry. I don't know what to suggest next.

Apache server gurus !!! HELP!

[samsm]

Can you give us a copy and paste of the line with $_SERVER, as well as the line before and the line after?

[pippo]

This is a long thread and I wasn't able to follow it,
but dragonfly is using php version 4.0.6....
(dragonfly it that's not true please correct me,
but I remember I asked that to you sometimes ago and also doing a netcraft to your website still show 4.0.6 )
That's the reason why he can't access _SERVER, _GET stuffs.
I can't remember how to access "get" variables under that php version, but php gurus will help you on that.



:-) pippo

[samsm]

Thanks Pippo, that did not even occur to me.
$HTTP_SERVER_VARS is the older array which behaves similarly to $_SERVER, except it is not a superglobal.

Deleted post...

[dragonfly_7456]

What do you mean by, it is not "superglobal"?

[dragonfly_7456]

Hey, it works! Haha! Alrighty!

[seanf]

What do you mean by, it is not "superglobal"?

It's not available *everywhere*, for example in functions, you have to pass it to the function

If anyone is still following this thread. LoL. Here is the end result coding that I used, which I put into the part of my coding, where the pages were to be switched.

<?php
$file = ( isset($HTTP_GET_VARS['page']) ? $HTTP_GET_VARS['page'] : 'default' ); 
$file .= ".php"; 
$check = @include($file); 
if (!$check) 
{ 
  include('missing.php'); 
} 
else 
{} 
?>

Default.php contains the content that is to show up on the index.php page, and missing.php is the content that shows when a file is missing, that was called through a query string.

Also, if you want, you can change 'page' to whatever you want. 'act' , 'pg', 'file'. Whatever you prefer.

[pippo]

Hey Dragonfly,
what happen if my server is www.example.com ( your server is www.example.net] ) and my server does not parse .php

If I call your script using:
www.example.net/index.php?page=http://www.example.com/bad-guy
then my file
http://www.example.com/bad-guy.php
will be interpreted in your server and that could do serious damages.

Okay, remote-include must be enabled...
BTW,
I'd suggest another approach.

Maybe an example could be:

<?php


$pagesList = array( "default", "pippo", "dragonfly" );


$page = isset( $HTTP_GET_VARS['page'] ) ? strtolower( $HTTP_GET_VARS['page']) : 'default'; 

if (in_array($page, $pagesList) ) {

   include( $page.'.php' ); 

} 

?>

or something like that .

This is dragonfly_7456.

I can't believe I got this to work, but I did it...

<?php 

$pagesList = array( "default", "missing", "help" ); 

$page = isset( $HTTP_GET_VARS['page'] ) ? strtolower( $HTTP_GET_VARS['page']) : 'default'; 

$check = @include($file); 

if (in_array($page, $pagesList) ) { 

   include( $page.'.php' ); 

}

elseif (!$check) 
{ 
  include('missing.php'); 
} 

?>

1. All pages load from index.php?page=
2. index.php loads default.php as the default page.
3. If a page exists but is not in the page list, it will show up as "Missing".
4. If a page is missing, and is called through index.php?page= you will get a default "Missing.php" page.
5. Pages that are in the list load correctly under index.php?page=page

Only problem is, what if my site gets to 100 pages. Will that increase page loading time, or will it still work fine?

[dragonfly_7456]

Ah. Got my account back.

So, will that cause loading time problems when there is over 100 pages?
