Just after that add the following:
Code:
// get only first 5 of zip code
if($taxmatch == "postcode"){
$myfield = substr($myfield,0,5);
}
This fix will only work when the CUSTOMER enters zip+4 NOT if the database is set up for zip+4!

Hope that helps!

What is the best way to set up the database to use and require Zip+4? The State of WA is telling us that because of the multiple taxes within each Zip that the ZIP+4 is the only proper method to use.

Also, there were questions/comments within the thread that asking about linking to the State of WA's database to check. Has anyone been able to do that?
