change $HTTP_GET_VARS without changing others

[whodaman]

I would like to go to the same url ex:

index.php?name=Models&orderby=tempOrder&sub=mysub&othersub=myOtherSub

but simply change one of the variables such as

orderby=myModel

without knowing/changing the other variables.

Is there a way I can define

$HTTP_GET_VARS['orderby']=myModel;

and refresh the page?

Thanks

Sure, you can do that.

Change the variable in $_GET (preferred over $HTTP_GET_VARS if you're running PHP version 4.1.0 or newer).

Loop through $_GET to create a new URL string.

Use
header ("Location: <yourURLstring>");
to redirect the browser.

But I don't know why you don't just put the same logic inside the same first script to which the form submits.

I might be missing something, but how do i loop though the $_GET URL string if I don't know/don't care what it is?

$_GET is just an associative array with a special scope. You can loop through an associative using foreach:

for ($_GET as $key => $value)
{
//do some stuff
}
