Data coming from a POST or GET is a string, by definition -- A URL just
doens't contain any data type information, and PHP isn't going to sit there
and try to guess what the data type of $x should be.
You'll need to check its validity as an integer by using something like
this:
if (strlen($quant
> I have a strange problem, when a user inputs the quantity
> into a text input field in a cart, I want to be able to test
> to see if the value is a integer if it isn't then default it to 1
>
> if ( !is_int($Qty) ) {
> $Qty = 1;
> }
Off the top of my head (and thus probably hideously wrong),
