Very simple PHP validation.

Please the big God to the code bar, I know is very simple, but I tried a lot of methods, not to jump is not moving. It's not going to come out.
Is implementation: Enter the box to write a zip code, and then verify that if it is 5 numbers jump to the next page, not 5 stay on the original page and add "ZIP code is not correct" after the input box.
Thank you to the great God.

Zip Code is a 6-digit number, right?

This is a basic form validation, JS is done. Why bother PHP?

JS just judge it.

You can try to write it yourself!

if (Ereg ('/\d{5}/', $string)) echo ' right ';

The main thing in this building is this PHP?

This use JS to judge on the line, you ask to lose the wrong after the prompt message, only with JS the simplest ~
