javascript - PHPでページから他のページに変数を渡す方法

Question

テーブル *order_management* に注文を追加するために使用される *book_order* ページがあり、order_id はそのテーブルで自動インクリメントされます。このページを送信した後、order_id を他のページ *book_order2* に渡して、同じ order_id の下に製品を追加します。そのために、order_id が自動インクリメントされない別の *order_management2* テーブルを作成しました。

私の要件は、book_order ページから book_order2 ページに order_id を渡したいということです。その変数は、追加し続けるまで覚えておく必要があります....新しい注文を追加したい場合は、book_order ページに移動します。 book_order2 ページを使用します。

注文番号をセッションに保存できます。このようにして、ページ間で保護され、永続化されます。

に注文を挿入したらbook_order.php、セッションに保存します。

$sql2=mysql_query(....); // inserting

if($sql2){
    $_SESSION['order_id'] = mysql_insert_id();
}

これでbook_order2.php、商品を挿入する前に注文 ID を取得できます。

$id = $_SESSION['order_id'];
// insert product with order_id = $id

session_start()PHP セッションを使用するには、セッションを使用するスクリプトの先頭でcalll を呼び出す必要があります。グローバル/ヘッダーインクルードがある場合は、そこで実行できます。

補足:

mysql_*廃止されました。PDO または MySQLi へのアップグレードを検討してください。これは、特にからアップグレードする場合に適した PDO チュートリアルですmysql_*。
変数を SQL に連結する代わりに、パラメータがバインドされた Prepared Statement を使用します。
