将会话数据解析为我的INSERT函数

Question

我正在尝试将我的member_data会话解析为我的函数，但我不确定如何执行此操作。我的功能是

function createTransaction(){
    // Insert into the transactions table
    $query1 = mysql_query("INSERT INTO transactions (mem_id, OrderDate, Ship_Phone, Ship_Address, Ship_City, Ship_County, Ship_PostCode, Ship_Country) VALUES()");
    if($query1) {
        // Get the highest ID in the transactions table. This should be the ID of the row we just inserted.
        $tempInfo = mysql_query("SELECT `order_id` FROM `transactions` ORDER BY `order_id` DESC LIMIT 1");
        $tempInfo = mysql_fetch_assoc($tempInfo);
        $orderId = $tempInfo['order_id'];

        // Insert into the transaction details table.
        $query2 = mysql_query("INSERT INTO `transactionDetails` (Order_ID, Product_ID, Price, Quantity) VALUES({$orderId}, {$item_id}, {$price}, {$each_item})");

        if($query2) {
            // Success.
        } else {
            // Error occurred.
            echo 'Query2 Error: ' . mysql_error();
        }
    } else {
        // Error occurred.
        echo 'Query1 Error: ' . mysql_error();
    }
}

值为（第3行），我想插入会话中的数据

$session_mem_id = $_SESSION['mem_id'];
$member_data  = member_data($session_mem_id, 'mem_id', 'mem_email', 'mem_password', 'mem_address', 'mem_city', 'mem_postcode', 'mem_county', 'mem_country', 'mem_first_name', 'mem_last_name', 'password_recover', 'allow_email', 'admin', 'mem_tel');

我该怎么做？
