Zip code verification

by SteveJo Posted: 15 years ago 1 replies

Hi!
How can I create on my site an error message when the user submits an invalid zip code?
For example, in this site: carinsurancequotes.com , if I submit the zip code 99999 I get an error message: Please enter a valid zip code.

This is the code on my site:

HTML Code:

<form action="the next page" method="get" name="form">
<input type="text" name="zipcode" maxlength="5" id="zipcode" />
<br />

<input type="submit" name="search" id="button" value=""/>
</form>

Thanks,
Steve

You need a zip-code database on the server side (using a script language like PHP) to be able to tell if it's valid or not.
