How to send the value of the prompt field to the PHP handler on the server to send the message.

For this I wrote the code, but something is missing, the handler does not see the value of the prompt field.

HTML form

<form style="display:none;" id="myform" action="mailer.php" method="POST"> <input type="email" name="email" id="email" value="" /> </form>

Javascript

 var email = prompt("Ваш e-mail", "@"); if (email != 'undefined') { document.getElementById("email").value; document.forms["myform"].submit(); }

Php

 if (isset($_POST['submit'])){ //получаем e-mail $email = $_POST['email']; $email = trim($_POST['email']); $email = strip_tags($_POST['email']); $email = htmlspecialchars($email); //проверка пустого поля if (empty($_POST['email'])) exit(); //фильтр e-mail if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { exit(); } //проверка e-mail if (!preg_match("/[0-9a-z_]+@[0-9a-z_\-^\.]+\.[az]{2,6}/i", $_POST['email'])) exit(); mail(...); mail(...);

    Assign a value from the javascript variable to the element on the page. Here

      document.getElementById("email").value;

    do not perform any actions. Make the assignment

      document.getElementById("email").value = email;

    UPD

    Working example (file 1.php)

     <?php header('Content-type: text/html; charset=utf-8'); if (isset($_POST['email'])){ var_dump($_POST); exit(); } ?> <form style="display:none;" id="myform" action="1.php" method="POST"> <input type="text" name="email" id="email" value="" /> </form> <script> var email = prompt("Ваш e-mail", "@"); if (email != 'undefined') { document.getElementById("email").value = email; document.getElementById("myform").submit(); } </script>
