如何验证表单然后移动到另一个页面PHP

Question

I have a form that is to submit a date via 3 drop down boxes. I currently have the form submitting to itself then checking to make sure the date is valid.

if(isset($_POST['submit']))
{
$day = $_POST['day'];
$year= $_POST['year'];
$month=$_POST['month'];
$date= $year.'-'.$month.'-'.$day;
//**********************************Validate Date
if (!checkdate($month,$day,$year)){
echo $error= "Invalid Date Please Renter";
}
}

I am curious how I should go about going to the next page with the variables if the date is valid. I am thinking header('Location: nextpage.php'); and using Session() ? it workss but I am wondering if that is the CORRECT way.

Answer 1

You could also call the header function like this:

header('Location: nextpage.php?year='.$year.'&month='.$month.'&day='.$day);

This way you don't need to worry about the session, and the data will be passed via $_GET parameters.
