Simple question!

Hey! I have a drop down field for my "register" form, but this is clearly easy to edit, I just used tamperdata for firefox and yeah...pretty easy, is there any way that you could prevent tampering with the values when submitting this form!?

You have to filter your data once you receive it at the server end, simple example:

<?php
$valid_values = array('male', 'female');
if(in_array($_POST['data_to_validate'], $valid_values))
{
    echo "Your data is valid";
}
else
{
    echo "Your data is invalid";
}
?>
