urldecode

Hi. I'm using a file as my error page, ie 403, 404 etc. What I want to do is
pass the error number to that page er error.php?err=404 and get the file to
pick up the 404 and then process it in the file to get a desired output. I
can't firstly get the value into the file from the url, secondly when i
input a value directly into the file to test ie I insert this line
$Error_Number = '404';
and i test to see if $Error_Number is = 403, 404 or 500. However no matter
what I put in i get no result. The file as it is is included.
-----------------------
<?php

define('IN_PHPBB', true);
$phpbb_root_path = './';
include($phpbb_root_path . '/extension.inc');
include($phpbb_root_path . '/common.'.$phpEx);

$userdata = session_pagestart($user_ip, PAGE_VIEWONLINE);
init_userprefs($userdata);

define('$Error_Number', true);
define('$Error_Message', true);
//define('$err', true);

//maybe??
$Error_Number = '403';//urldecode($err);
echo $Error_Message;
//end maybe??

if('$Error_Number' == 403){
$Error_Message = "You are not authorized to view this page.<br>You might
not have permission to view this directory or page using the credentials you
supplied.";
}
else if('$Error_Number' == 404){
$Error_Message = "The page cannot be found.<br>The page you are looking for
might have been removed, had its name changed, or is temporarily
unavailable.";
}
else if('$Error_Number' == 500){
$Error_Number = 500;
$Error_Message = "The page cannot be displayed.<br>There is a problem with
the page you are trying to reach and it cannot be displayed.";
}

$page_title = "Error " . $Error_Number;
include($phpbb_root_path . 'includes/page_header.'.$phpEx);

$template->set_filenames(array('body' => 'error_body.tpl'));

$template->pparse('body');

include($phpbb_root_path . 'includes/error_tail.'.$phpEx);

?>
-----------------------
Please please please help.

This may not be the problem but when you initialise a variable using quotes
as you have here, you are defining your error "number" as a string. I think
it's bad programming style to have a variable called $Error_Number that is
in fact a string.

Same story here, You don't need the quotes around the variable name but you
do need the quotes around 403 because you have previously defined it as a
string.

So to sum up try either:

$Error_Number = 403;
if($Error_Number == 403){
$Error_Message = "You are not authorized to view this page.<br>You might
not have permission to view this directory or page using the credentials
you
supplied.";
}



Or this:



$Error_Number = '403';
if($Error_Number == '403'){
$Error_Message = "You are not authorized to view this page.<br>You might
not have permission to view this directory or page using the credentials
you
supplied.";
}


The first stores $Error_Number as an integer value as far as PHP is
concerned and the second stores $Error_Number as a string.

I think the first is preferable.

Ok. I've done that but it still desn't do what I want. The url would be
http://www.somewhere.com/forum/error.php?err=404 I want to get the err=404
part of that url in to my file. I believe that to do that you must decode
the url but all i get as a value then is "Array" and that definaetly isn't
404.

-----------------------
define('$Error_Number', true);
define('$Error_Message', true);

//maybe??
$Error_Number = urldecode($err); //HERES THE PROBLEM
//end maybe??

if($Error_Number == '403'){
$Error_Message = "You are not authorized to view this page.<br>You might
not have permission to view this directory or page using the credentials you
supplied.";
}
else if($Error_Number == '404'){
$Error_Message = "The page cannot be found.<br>The page you are looking for
might have been removed, had its name changed, or is temporarily
unavailable.";
}
else if($Error_Number == '500'){
$Error_Number = 500;
$Error_Message = "The page cannot be displayed.<br>There is a problem with
the page you are trying to reach and it cannot be displayed.";
}

$page_title = "Error " . $Error_Number;
include($phpbb_root_path . 'includes/page_header.'.$phpEx);

You do not need to use the urldecode function. You should already have
access to that variable in your script and it will be called $err. If that
does not work then you probably have the "register_globals" variable set to
"off". That is a good thing for security. (look for register_globals in the
php.ini file and read more here: http://www.php.net/register_globals )

So, if you have register_globals set to "off" the above line needs to be:

$Error_Number = $_GET['err'];

Otherwise:

$Error_Number = $err;

Thats perfect. Thanks you very much Andrew. I used $Error_Number =
$_GET['err']; as the other one didn't work. Thanks again.
