Querystring Function

wilhud

I'm trying to write a function that will take the querystring variables I pass to it and then format them accordingly. Here's what I have so far...

function getQuerystring($Variable,$Default) {
if ($Variable == "") {
// this is the first problem line because I don't know how to dynamically set the Variable name
$$Variable = "$Default";
} else {
// the second problem line, same reason
$$Variable = trim($Variable);
}
}

It would be called with...

getQuerystring($strSortOrder,"asc");

The first variable would be the querystring element and the second would be the default value.

I know why this isn't working, but I don't know how to write it in php so that it will work. Any ideas?

Thanks,
Wil

I guess what I'm asking is, how can change the value of a dynamic variable inside of a function and then pass it back to the php page. Or is this even possible.

Thanks,

Why not just use $GET as that will already have the query string formatted into $GET['var'] == 'value';

This worked, not sure if it's a good way to do it or not though...

function getQuerystring($Variable,$Default) {
if ($Variable == "") {
$VariableOut = "$Default";
} else {
$VariableOut = trim($Variable);
}
return $VariableOut;
}

$strSortBy = getQuerystring($strSortBy,"date");
$strSortOrder = getQuerystring($strSortOrder,"asc");

It works and I can keep using it for as many variables as I need to. That way I don't have to write a bunch of if statements to set defaults, in the case that there was no querystring submitted.
