Question

I have an email form, that i'm validating a date, its a booking form. What im doing is when the start date is bigger than the end date it gives me a message saying to fix the date and redirect to the page. I have 2 pages, the page of the booking form, and when i click to submit it goes to the contact_engine page to validate and send the email:

here is how i put it:

if ($datebegin >= $dateend){
    echo '<script>alert("Fix the Date");</script>'; 

exit;

The problem is when it does the exit it stays in the functions page, and i want it to exit but go to the previous page. Can someone give me some help? I tried instead using exit. I try to use it with header("Refresh: 1; url=http:/website.com/booking.php"); but somehow this takes me to the to the sent_page_booking page.

Answer 1

What about doing a timed redirect, so that the user gets the error message shown:

header("refresh:5;url=back-to-booking-form.php");
echo 'Form Error. Fix the date. Redirecting to the booking form in about 5 secs.';
