small prob

[Anon]

I am trying to validate a zip code from a form using the following code.

if (!is_int($zipcode) || $zipcode == ""){
$error[] = "Zip Code"; //error array
}

I don't know why this won't work? Can someone please help.

Thanks

you must specify the arryfield:
$error[0] = "Zip Code";

Thanks, but my problem is not the array. The array will be created whether I give it a key or not. My problem is that my "OR" statement will not return true. I want to make sure that the visitor filled anything in the form field ($zipcode ==""), and if they did, make sure it is an integer(is_int($zipcode)).

Narch, don't post your problems in more than one forum. It's very bad form.

Nico, you're mistaken, the way he's adding to the array is perfectly valid.

I had a similar problem, and fixed it by replacing

$zipcode == ""

with

empty($zipcode)

empty() tests for "" and for unset variables as well.

It should also be possible to solve it like this:

if (!is_int($zipcode) || !$zipcode){
$error[] = "Zip Code"; //error array
}

...since php considers this empty variable as FALSE.
