以下に、Ajax フォームの送信からテーブルを備えた適切な HTML メールを作成する PHP コードをいくつかまとめました。ただし、入力した時間枠が48時間未満の場合、エラーメッセージが表示されるようにしたかったのです。これを機能させるために、html と php を変更する最も簡単な方法は何か、またはそれが可能かどうかを知りたかったのです。

<input name="Event Date" type="text" required id="Event Date" style="border-radius:5px; height:25px; font-family:'Quicksand', sans-serif; color:#666" title="Event Date" value="MM/DD/YYYY">
