urldecode() problem

[machina3k]

I've just installed apache/php/mysql on XP Home and everything was going great until I tried to execute a script that I had coded previously (and it previously worked). The problem is that when I try to get variables from the query string using urldecode().

The script essentially is:

<?PHP

$action = urldecode($action);

echo $action;

?>

The error I get from that whether the variable 'action' exists
or not is:

Notice: Undefined variable action in : C:....... on line 3

I've read a few threads about the same notice but no one
mentions using urldecode to get from the query string.

Any help would be greatly appreciated 🙂

Thanks

Hi,
you have to set a value for $action or pass one...

<?PHP
$action = urldecode($action);
echo $action;
?>

If $action is nothing what it can urldecode?

You can set it before
<?PHP
$action="%20%20%20"
$action = urldecode($action);
echo $action;
?>
or call the script whit "?action=%20%20%20" appended to the url

mytest.php?action=%20%20%20
<?PHP
$action = urldecode($action);
echo $action;
?>

In this second if you don't have globals var on (you can read on phpinfo()) you must use $_GET[] array:

mytest.php?action=%20%20%20
<?PHP
$action = urldecode($_GET["action"]);
echo $action;
?>

good luck.

lol, i'm such an idiot.

For some reason when I've been coding scripts on a remote webserver and I had a query string like index.php?action=whatever I would do:

$value = urldecode($action);

and it would return 'whatever'. Never made sense to me but
because it worked i just forgot about it.

Anyway, it all works now.

Thanks a lot for your help 🙂
