hey,
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;
}
Looks ok, should work in theory, but it doesn't if I use this test, the update on the
database fails, take it out and it works, so if a user was to type "f" in the quantity
field in the cart and hit update because the quantity field is int(2) in the database
it will default to 0 which I do not want. I have also tried to set the type before the
update like so:
$Qty = settype($Qty, "integer");
This also will make the update fail, how would I make sure a user does not type
characters in the quantity field without using javascript or ereg stuff to check the
values? I just want to default the quantity to 1 if a invailid quantity is inputted.
If there is no obvious soulution then I will use a piece of javascript to check the
field onSubmit for illegal characters and alert the user I guess.
Regards,
Joseph
