http://rosstanner.co.uk/2012/11/build-simple-contact-form-html-php-bootstrap/に基づいて html / php フォームを作成しました

フォームが正常に検証され、メールが送信されます。ただし、フォームが無効化された場合、ユーザーは index.php に戻されますが、入力したフォームの値は失われます。これは明らかにユーザーが経験した悪いことです。

私はこれを修正するためにクッキーを使用しようとしましたが、私はその悪い習慣を感じており、とにかくiPhoneでは動作しないようです. これを達成する方法はありますか？

index.php

        <h3><a name="book">Send a booking enquiry</a></h3>

        <p>We are in the process of building a new booking system. In the mean
        time please enter your details below and you will be contacted
        shortly.</p>

        $return_form_vals = array();

 if (isset($_COOKIE['cookie'])) {
 foreach ($_COOKIE['cookie'] as $name => $value) {
  $return_form_vals[htmlspecialchars($name)]=htmlspecialchars($value);
    }

間違ったデータを送信するのを防ぐために、フォームを送信する前にjQuery検証リンクを使用してユーザー入力を確認する$_SESSION['name']=$value;代わりに、データを保持することをお勧めします。次に、ユーザーが各フィールドに有効な情報を挿入することに気付くことができます。例:リンク$_COOKIE

空の必須フォームフィールドの送信を防ぐにrequired は、たとえば HTML 属性を使用できます

<input class="textfield" name="your_name" placeholder=
              "Enter your name" value="<?php echo $return_form_vals['your_name'];?>" type="text" required="required"><br>

フォームは、すべての必須フィールドが入力される前にユーザーが送信することを許可しません
