scope of variables outside of an if statment

[rougue]

i've run into an intersting problem working with if statement.

I'm trying to pass variable into the php script which would be gotten via the $GET variable. My if statement if based on a button so when the user pushes the button it will process the data and such. But when it is inside the if statement it seems thati cannot access any variables i decalared outside of the if, this includes $GET. I've looked at other scripts that i have and inside of if statement i see post and files being accessed so is there something im doing wrong in the new script or is it just how php works? thanks in advance

we need to see code.

$_GET is a superglobal variable so it is available everywhere. Post your code so we can see what else you're doing that may be causing the problem.

There is no variable scope issues in an if() statement unless the if() statement is inside a user defined function.

[rougue]

<?php
$submit = $POST['submit'];
$thing = $GET['thing'];
if($submit && $thing)
{

$userpass = $_POST['password'];
switch($thing) {
case 'upload':
if($userpass =="uploading")
{
echo "<a href='upload.php'>Continue</a>";
}
break;
default:
echo "<a href='index.php'>Continue</a>";
}
else
{
//display form stuff blah blah blah
}
?>

How are you getting POST and GET varibles in the same script?

[rougue]

the post is coming from a form (textbox and submit button)

the get is coming in the form scriptpage.php?thing=uploading

as in from a link

you can only have one method at a time. You can't POST and GET at the same time. It's either 1 or the other.

If your script is doing both, you need to check for which one is the current method checking $_SERVER['REQUEST_METHOD'] in an if statement.

BUT there is an easier solution.

try this:

import_request_variables("gp");
if($submit && $thing){
...
}

import_request_variables will read your GET, POST, or COOKIE values into the global namespace.

see:
http://www.php.net/import_request_variables
for more information.
