How can I create on my site an error message when the user submits an invalid zip code?
For example, in this site: http://www.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:
- Code: Select all
<form action="http://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
