PHP form redirect to thanks page

问题:

I have a custom WP theme that I'm trying to redirect to a thanks page after the form has been verified. I know there are a ton of other questions very similar, but I've tried the "headers" trick and all of the other suggestions, but my page just keeps going back to the contact.php page. Hovering over the submit button (before clicking it) shows mypageURL.com/contact, instead of mypageURL.com/thanks. Here is my code.

<?php 
//Verify the email address
function isemail($email) {
    return preg_match('|^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]{2,})+$|i', $email);
}
//set variables
$error_name = false;
$error_email = false;
$error_message = false;
//Get form values
if (isset($_POST['contact-submit'])) {
    $contact_name = '';
    $contact_email = '';
    $contact_subject = '';
    $contact_message = '';
    $contact_reciever = '';

    if (trim($_POST['contact_name']) === '') {
        $error_name = true;
    } else {
        $contact_name = trim($_POST['contact_name']);
    }

    if (trim($_POST['contact_email']) === '' || !isemail(trim($_POST['contact_email']))) {
        $error_email = true;
    } else {
        $contact_email = trim($_POST['contact_email']);
    }

    $subject = trim($_POST['contact_subject']);

    if (trim($_POST['contact_message']) === '') {
        $error_message = true;
    } else {
        $contact_message = stripslashes(trim($_POST['contact_message']));
    }

    //Check for errors
    if (!$error_name && !$error_email && !$error_message) {
        //Get reciever email
        if( get_theme_mod( 'custom_contact_form_mail' ) != '') $get_contact_reciever = get_theme_mod( 'custom_contact_form_mail' ) ;
        $contact_reciever = $get_contact_reciever;

        $the_subject = 'New message: ' . $contact_subject;
        $the_message = 'Message from: ' . $contact_name . PHP_EOL . 'Email: ' . $contact_email . PHP_EOL . PHP_EOL . $contact_message . PHP_EOL ;

        $the_headers = "Form " . $contact_email . PHP_EOL . 'Reply-To: ' . $contact_email . PHP_EOL . 'MIME-Version: 1.0'  . PHP_EOL . 'Content-type: text/plain; charset=utf-8'  . PHP_EOL . 'Content-Transfer-Encoding: quoted-printable'  . PHP_EOL;

        if (mail($contact_reciever, $the_subject, $the_message, $the_headers)) {
            $contact_form_sent = true;
        } else {
            $contact_form_sent_error = true;
        }
    } else {
        $contact_form_not_filled = true;
    }
}

It's not really a trick, its how you can do exactly what you want done.

if (mail($contact_reciever, $the_subject, $the_message, $the_headers)) {
    $contact_form_sent = true;
    header("Location: " . get_permalink($THANKYOU_PAGE_ID));
}

Does it throw off any errors when you try using header? If so you might have to create a hook and verify the form earlier in the page load.

I'm assuming your comment means "Yes it is throwing off errors, how do I hook my form earlier so that it doesn't do that?". Well my good friend follow me..

add_action( 'send_headers', 'form_verify' );
function form_verify() {
    // add form code here with header code
}
