小编use*_*124的帖子

我已经使用预准备语句将订单插入到订单表中,但现在我想根据订单表中插入的最后一个ID将订单商品插入到订单商品表中:

if (isset($_POST['process'])) {

    $order_name = $_POST['order_name'];
    //create initial order
    $stmt = $conn2->prepare("INSERT INTO orders (order_name) VALUES (?)");
    $stmt->bind_param('s', $order_name);
    $stmt->execute();

    //this gets the most recent auto incremented ID from the database - this is the order_id we have just created
    $order_id = mysql_insert_id();

    //loop over all of our order items and add to the database
    foreach ($_SESSION['order'] as $item) {

什么相当于mysql_insert_id();使用准备好的声明？

这段代码有效,但我想弄清楚如何更改$ rose = mysql_fetch_assoc($ stmt); 部分为"预备声明风格".谁知道？

$rose_id = $_GET['rose_id'];
  //prepare the statement
  $stmt = $conn2->prepare("SELECT * FROM rosename 
            LEFT JOIN rosevariety ON (rosename.variety_name = rosevariety.variety_name) 
            WHERE rose_id = ?");

            //bind the parameters
  $stmt->bind_param("i", $rose_id);

  //$sql = mysql_query($query, $conn);
  $stmt->execute();

  //was there a good response?
  if ($stmt) {

    $rose = mysql_fetch_assoc($stmt);

    //echo out rose information
    echo "<h1>".$rose['latin_name']."</h1>";
    echo "<h2>".$rose['common_name']."</h2>";
