如何将产品ID从一个页面传递到另一个页面，以便在PHP中插入该产品的图像？

Question

Answer 1

product-details.php

<?php

$result = mysqli_query($connection, $some_insert_query_here);
if($result){
     $lastId = mysqli_insert_id($connection);
     header("Location: product-image.php?id=".$lastId);
}
?>

product-image.php

<?php

if(isset($_GET['id'])){
     $lastId = $_GET['id'];
     // do stuff with this last inserted product id
}


?>

or try sessions:

product-details.php

<?php

    $result = mysqli_query($connection, $some_insert_query_here);
    if($result){
         $lastId = mysqli_insert_id($connection);

         session_start();
         $_SESSION['last_id']  = $lastId;
         header("Location: product-image.php");
    }
    ?>

product-image.php

<?php
session_start();
if(isset($_SESSION['last_id'])){

     $lastId = $_SESSION['last_id'];
     // do stuff with this last inserted product id
}


?>
