添加1个字段断开PHP联系表单

Question

一切正常，直到我在电话号码的字段中添加。如果我将其删除，则会发送电子邮件。

我输了=＆＃39; tel＆＃39;但它也没有用。我尝试了我可以找到的任何变种来解决问题，唯一可行的是从html和php中删除所有电话字段的痕迹。

HTML：

<form id="main-contact-form" class="contact-form" name="contact-form" method="post" action="sendemail.php" enctype="multipart/form-data">
                    <div class="form-group">
                        <input type="text" class="form-control" id="Name" name="name" placeholder="Name" required="required">
                    </div>
                    <div class="form-group">
                        <input type="email" class="form-control" id="Email" name="email" placeholder="Email">
                    </div>                    
                    <div class="form-group">
                        <input type="text" class="form-control" id="Phone" name="phone" placeholder="PhoneNumber">
                    </div>
                    <div class="form-group">
                        <textarea class="form-control" rows="3" name="message" placeholder="Message" required="requried"></textarea>
                    </div>
                    <button type="submit" name="submit" class="btn-block" >Send</button>
</form>

PHP（代码段）：

$name = @trim(stripslashes($_POST['name'])); 
    $clientemail = @trim(stripslashes($_POST['email'])); 
    $phone = (stripslashes($_POST['phone']));
    $message = @trim(stripslashes($_POST['message']));

    $body = 'Name: ' . $name . "\n\n" . 'Email: ' . $clientemail . "\n\n" . 'Phone: ' . $phone . "\n\n" . 'Message: ' . $message;

     $email = new PHPMailer();      

    $email->From      = $clientemail;
    $email->FromName  = $name;
    $email->Subject   = 'Message from Website User';//$subject;
    $email->Body      = $body;  
    $email->AddAddress( 'johndoe@gmail.com' ); //Send to this email

 // EXPLICITLY TELL PHP-MAILER HOW TO SEND THE EMAIL... IN THIS CASE USING PHP BUILT IT MAIL FUNCTION    
        $email->isMail();

    header("Content-Type: application/json; charset=utf-8", true);

 // NOW, TRY TO SEND THE EMAIL ANYWAY:
        try{
            $success    = $email->send();
            $status['type']    = 'success';
            $status['message']  = 'Thank you for contacting us. We will reply as soon as possible.';   
        }catch(Exception $e){
            $status['type']     ='Error';
            $status['message']  ='Couldn\'t send the Email at this Time. Something went wrong';     
        }   

        // SIMPLY, RETURN THE JSON DATA...
 die(json_encode($status));

这是我的JS / AJAX：

   /***************** Contact Form Submission ******************/

$(document).ready(function (e){
$("#main-contact-form").on('submit',(function(e){
    e.preventDefault();
    $('#sendingemail').fadeIn();
        $.ajax({
        url: "../sendemail.php",
        type: "POST",
        data:  new FormData(this),
        contentType: false,
        cache: false,
        processData: false,
        success: function(data){
            console.log(data);
            if (data.type == 'Error') {
                    //alert(data.message);
                  $('#sendingemail').fadeOut();
                  $("#notsent").html(data.message).fadeIn();
                }
            else{
                $('#sendingemail').fadeOut();
                $('#emailsent').fadeIn();
              //alert(data.message);
            }
        },
      error: function(XHR,textStatus,errorThrown) {
            //alert("error");
              console.log(XHR.status + "..." + textStatus + "..." + errorThrown);
              alert(XHR.status);
            alert(textStatus);
            alert(errorThrown);
        }
    }           
 );
}));
});
