これはライブの商用プロジェクトのためのものなので、どんな助けも大歓迎です.
私はPHPとjQuery / Javascriptに比較的慣れていないので、私がすでに持っているもののほとんどがあなたの専門家が考えるものである場合は許してください...がらくた:)
- 私のウェブサイトは HTML のみで、PHP メール フォームを使用するコンタクト フォームがあります (コンタクト フォームは HTML ドキュメントのままです)。
- jQuery Validate を使用して、満足できるレベルで機能するクライアント側の検証を実装しました。
- また、PHP フォーム スクリプト内にサーバー側の検証とサニタイズも実装しました。
クライアント側とサーバー側の検証は正しく連携しているように見えますが、サーバー側の PHP スクリプトによって生成されたエラー メッセージを表示する方法に頭を悩ませています。
クライアント スライドの jQuery 検証は問題なく動作します。contact.html ページに、正しいエラー メッセージを表示するエラー メッセージ コンテナー DIV があります。ただし、サーバー側では、送信を押すと、contact-form.php がブラウザーに読み込まれ、エラー メッセージ (または成功メッセージ) が空白のページに表示されます。
私が望むのは、contact-form.php ファイルからの出力エラー メッセージを、実際にページを離れることなく、jQuery と同じエラー コンテナー DIV に表示することです。
私がこれをやろうとしている理由は - ユーザーが JavaScript を有効にしていない場合、jQuery バリデーターは明らかに機能しません - しかし、それでも jQuery 処理と同じくらい洗練された PHP エラー処理が必要です。
時間を割いて読んでアドバイスしていただきありがとうございます。
これが私のコードです。
