its probably not catching the $_POST['submit'] for some reason.. try something else like if($_POST['username']){ let me know if that works...

Hi

Thanks that has worked great, the only thing is, is there any way that if an error is detected then you will be redirected to another page with the results displayed on that page, because at the moment the errors display at the top of the page and the table with blank fields appear below it?

Any suggestions

Regards

Jackie

I'd suggest using the same page for the error display. Just create an "error" variable and set to true if you find an error during validation. Then create a switch to show the page normally if the error variable is false and to show the error page if the error variable is true. hope that makes sense.

Hi

That sounds like exactly what I need but I not sure how to do it, I have tried to look up a way to set this up but can't seem to find one, could anyone point me in te right direction!

Thanks

Jackie

Anyone

Ok, I took a closer look at your code, and you already have all the pieces to do this. you just need top put it all together.

You have an array called $errors. So after the validation lines add a switch to check the length of $errors. If it equals > 0, then display the page as you want it when there are errors. Else, display the page as you want for no errors.

[code]<?php
if (count($errors)>0) {
//Display the erros page
} else {
//display the no error page
}
?>[/code]
