Проверка формы PHP (не знаю, как разделить ее на две разные страницы)

Я работаю над контактной формой в PHP. Мое знание PHP практически не существует.

Я пробовал какое-то время, чтобы получить HTML-форму для отправки в форму PHP, чтобы ее текстовые поля были проверены и необходимы, если они пустые, но не могут заставить ничего работать. Я также не знаю AJAX, иначе бы попытался это сделать.

• Как остановить XMLHTTP от столкновения друг с другом?
• Выражение PHP <<< EOB
• как я могу импортировать файл excel с помощью php и печатать его в таблице html
• Многопользовательский поисковый запрос PHP MySQL с использованием опции / выбора тегов HTML-формы
• Меню навигации PHP и активный стиль страницы

Таким образом, прибегают к созданию собственной формы PHP внутри HTML-страницы.

Это текущая версия:

<?php // define variables and set to empty values $firstNameErr = $lastNameErr = $emailErr = $messageErr = ""; $first_name = $last_name = $email = $message = ""; if ($_SERVER["REQUEST_METHOD"] == "POST") { if (empty($_POST["first-name"])) { $firstNameErr = "First name is required"; } else { $first_name = test_input($_POST["first-name"]); } if (empty($_POST["last-name"])) { $lastNameErr = "Last name is required"; } else { $last_name = test_input($_POST["last-name"]); } if (empty($_POST["email"])) { $emailErr = "Email is required"; } else { $email = test_input($_POST["email"]); } if (empty($_POST["message"])) { $messageErr = "Message is required"; } else { $message = test_input($_POST["message"]); } } function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data; } ?> 

Это форма на той же странице:

 <form class="ui form" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> <div class="field"> <label>First Name</label> <input name="first-name" id="first-name" placeholder="First Name" type="text"> <span class="error">* <?php echo $firstNameErr;?></span> </div> <div class="field"> <label>Last Name</label> <input name="last-name" id="last-name" placeholder="Last Name" type="text"> <span class="error">* <?php echo $lastNameErr;?></span> </div> <div class="field"> <label>Email</label> <input name="email" id="email" placeholder="Email" type="email"> <span class="error">* <?php echo $emailErr;?></span> </div> <div class="field"> <label>Message</label> <textarea rows="2" placeholder="Please type in your message" name="message" id="message"></textarea> <span class="error">* <?php echo $messageErr;?></span> </div> <button class="ui button" type="submit">Submit</button> </form> 

Есть ли способ сделать это на двух разных страницах, т. Е. Сформировать на первой странице и перенести на вторую страницу в режиме сеансов? Или это приемлемо для коммерческого сайта? Пожалуйста, дайте мне знать. Спасибо.

  if (empty($_POST["email"])) { $emailErr = "Email is required"; } else { $email = filter_vars(test_input($_POST["email"], FILTER_VALIDATE_EMAIL)); }

Я включил это в конец файла php, т. Е. После функции test_input. header('location: php_mailer_form.php'); Это правильное размещение?

Но по какой-то причине, когда я пытаюсь посетить форму contact.php, она даже не появляется, она просто переходит прямо к форме ошибки, которая у меня есть в нижней части php_mailer_form.php.

  if(!$mail->send()) { header('location: url/contactError.html'); } else { header('location: url/contactResult.html'); } 

Зачем? (пожалуйста, дайте мне знать, если мне нужно включить дополнительную информацию).
