HTML / PHP联系人表单不发送数据到我的gmail

我一直在试图解决这个问题，我在这里和其他论坛找到的解决方案，但似乎没有任何工作。我对PHP一窍不通。我不知道这个信息是否相关，但我在byethost.com上托管我的项目，他们说它支持PHP。

我在我的HTML联系人页面中制作了一个联系人表单，制作了一个PHP文件来处理数据并将其发送到我的gmail地址。它说消息已成功发送，但数据从未到达我的gmail收件箱。我尝试过用其他方法更改PHP代码(使用复制粘贴解决方案)，但没有运气。我也试着把它发送到我的hotmail账户，但也不行。有人能帮我吗?

下面是HTML联系人表单:

     <div id="form_wrap">
        <form method="post" action="form_process.php" id="contact_form" class="contact">
                <label>
                    <span>NOME*</span>
                    <input name="nome" type="text" tabindex="1" required>
                </label>
                <label>
                    <span>E-MAIL*</span>
                    <input name="email" type="email" tabindex="2" required>
                </label>
                <label>
                    <span>TELEFONE*</span>
                    <input name="phone" type="tel" tabindex="3" required>
                </label>
                <label>
                    <span>WEBSITE</span>
                    <input name="website" placeholder="http://" type="url" tabindex="4">
                </label>
                <label>
                    <span>MOTIVO DE CONTACTO*</span>
                    <select class="escolha" name="motivo" size="1" tabindex="5" required>
                    <option>Contratá-lo</option>
                    <option>Fazer uma pergunta</option>
                    <option>Dizer olá ou agradecer</option>
                    </select>
                </label>
                <div>
                <label>
                    <span>MENSAGEM*</span>
                    <textarea name="message" tabindex="6" required></textarea>
                </label>
                </div>
                <div>
                <input name="submit" type="submit" value="Enviar" id="submit">
                </div>
        </form>
            <a class="subtop" href="#subtop">&#8211; Voltar ao topo</a> 
        </div>

这是我的form_process.php:

    <?php
if(isset($_POST['submit'])) {
$nome = $_POST['nome'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$website = $_POST['website'];
$motivo = $_POST['motivo'];
$message = $_POST['message'];
$to = "mygmailadress@gmail.com";
$subject = "Site contact form";
$header = "From: ".$fromText."'r'n";
$header .= "Cc: ".$ccText."'n";
$header .= "Reply-To : ".$fromText."'r'n";
$header .= "Return-Path : ".$fromText."'r'n";
$header .= "X-Mailer: PHP'r'n";
$header .= "MIME-Version: 1.0'r'n";
$header .= "Content-Type: text/plain; charset=iso-8859-1'r'n";
mail($to, $subject, $header, $message, "From: " . $nome);
}
if(@mail($emailRecipient, $subject, $message, $headers))
{
  echo "Mail Sent Successfully";
}else{
  echo "Mail Not Sent";
}
?>

  if(mail(...)) {
    echo 'good times';
    } else {
    echo 'boo, no email was sent';
    }

bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

<?php
    if(isset($_POST['submit'])) {
    $nome = $_POST['nome'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $website = $_POST['website'];
    $motivo = $_POST['motivo'];
    $message = $_POST['message'];
    $to = "asdf@gmail.com";
    $subject = "Site contact form";
    $header = "From: ".$email."'r'n";
    $header .= "Cc: ".$email."'n";
    $header .= "Reply-To : ".$email."'r'n";
    $header .= "Return-Path : ".$email."'r'n";
    $header .= "X-Mailer: PHP'r'n";
    $header .= "MIME-Version: 1.0'r'n";
    $header .= "Content-Type: text/plain; charset=iso-8859-1'r'n";
    if(mail($to, $subject, $message, $header))
    {
      echo "Mail Sent Successfully";
    }else{
      echo "Mail Not Sent";
    }
    }
    ?>
