Hiya,

I've got a fairly basic understanding of PHP but i'm learning all the time.

I have a really basic form, that i'd like to submit by email using php, i know how to send the email, but i want to ensure that things are filled in before i send the form.

I know i need to submit the form to itself so i can put the bits that ARE filled in back in and highlight the bits that havent been.

What i'm wondering is how can i make the script only send the results by email IF all the fields are filled in? and just display the form again if they're something missing? (i know how to do the validation).

I might be having a slow day or something, cos i'm sure this should be fairly simple.

Thanks.

Andy

<?php
if($_POST['email'] == \"\" || $_POST['name'] == \"\")
{
echo \"<p>Please fill in all required fields</p>\";
}
else
{
echo \"<p>Message has been sent</p>\";
}
?>

I just created this on the fly, obviously if you have alot of things to validate then the if function is going to get very long. Maybe someone can think of someway to loop through all your $_POST variables
