新規会員登録ページを作成中です。フォームに入力すると、確認ページに進みます。確認後、reg_add.php に進み、フォームからデータベースにデータを追加します。
reg_new.php --> reg_confirm.php --> reg_add.php
確認ページ (reg_confirm.php) のコードを編集して、メールの可用性チェックを含めようとしています。重複したメールを自動で検出して確認ボタンをクリックした後だと思われます。
キー「PRIMARY」の重複エントリ「shop@gmail.com」が表示されます。
ただし、ポップアップ アラートが表示され、確認ページにとどまることは成功ではありません。助けてください。
