使用302重定向表单

<form action="http://www.website.com/add" method="post" target="_blank" >
    <select name="productid">
    <option value="84215_212">Size S</option>
    </select>
    <input type="hidden" value="1" name="xQuantity">

    <button class="button" type="submit"">
    <span>Add to bag</span>
    </button>

I would like to set my form above to send the request as "302 Moved Temporarily" instead of "200" after submitting which would then redirect to http://www.website.com/cart with GET request. How do I implement this? Thanks.

Add the following at the top of the script handling /add:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // do something, then
    header('Location: /cart', true, 302);
    exit();
}
?>

I would like to set my form above to send the request as "302 Moved Temporarily" instead of "200"

Note, the code for "Moved Temporarily" is 301, not 302 (which is a code for "Found").
