[Resolved] Unwanted elimination of zero in POST value

Hello all.
I have a form page with a field for Zip Codes:

Code:

---

<input type="text" name="customer_zip">

---

Now, some Zip Codes, in New Jersey in particular, begin with a zero. As in 01234.
When this field gets posted, the zero in the front gets trimmed.
I don't know if it's the operating system (Win 2k Server) or PHP.
Does anyone know how I can rectify this situation?
Many thanks.

i think its thge operating system cause wenever i wanna trim something i gotta use the trim(); function

could i see an example of how you are using it?.... cuz it sounds kinda funky to me.

who? me or him

All post variables should be sent to the PHP script as strings. So unless an operation in your script has cast the data type of the variable to a numeric type, the zero should remain.

To force a string type when carrying out operations on the variable you should explicitly cast it each time:

Code:

---

$customer_zip = (string) $_POST['customer_zip'];

That did it, visualAd. Thanks.
