Why is php's mail() function successfully sending mail but with blank fields?

问题

Email is arriving at the destination address but with blank fields. What is the cause?

My use of mail() is as follows:

<?php
header('Content-type: application/json');
$status = array(
'type'=>'success',
'message'=>'Email sent!'
);

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

$email_from = $email;
$email_to = 'info@siteaddress.com';

$body = 'Name: ' . $name . "\n\n" . 'Email: ' . $email . "\n\n" . 'Subject: ' . $subject . "\n\n" . 'Message: ' . $message;

$success = @mail($email_to, $subject, $body, 'From: <'.$email_from.'>');

echo json_encode($status);
die; 
?>

And the form HTML is:

<form id="main-contact-form" class="contact-form" name="contact-form" method="post" action="sendemail.php" role="form">
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<input type="text" class="form-control" required placeholder="Name" name="name" id="name">
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<input type="text" class="form-control" required placeholder="Email address" name="email" id="email">
</div>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<div class="form-group">
<textarea name="message" id="message" required class="form-control" rows="8" placeholder="Message" name="message" id="message"></textarea>
</div>
<div class="form-group">
<button type="submit" class="btn btn-danger btn-lg">Send Message</button>
</div>
</div>
</div>
</form>

$subject = @trim(stripslashes($_POST['subject'])); but your form don't have subject, you should add it.
Don't suppress errors by @, because you never will know what exactly happens with your code.

Finally Got the Answer.... Problem is that my form was not posting anything because the following script was missing

<script>
var form = $('.contact-form');
form.submit(function () {
    $this = $(this);
    $.post($(this).attr('action'),$(this).serialize(), function(data) {
        $this.prev().text(data.message).fadeIn().delay(3000).fadeOut();
    },'json');
    return false;
});
</script>

i have added $(this).serialize() to the script and now the mail is working properly...

Thanks all of you....

Hi I´m have the same problem on a 000webhost app. I solve this with two moodifications 1rst: Add var name = $("input#name").val(); for a form values and in to the ajax function name: name, for a form values

var form = $('#main-contact-form');
form.submit(function(event){
    event.preventDefault();     
        var name = $("input#name").val();
        var email = $("input#email").val();
        var subject = $("input#subject").val();
        var message = $("textarea#message").val();

    var form_status = $('<div class="form_status"></div>');
    $.ajax({
         url: $(this).attr('action'),
            type: "POST",
            data: {
                name: name,
                email: email,
                subject: subject,
                message: message,
            },
            cache: false,

        beforeSend: function(){
            form.prepend( form_status.html('<p><i class="fa fa-spinner fa-spin"></i> Email enviandose</p>').fadeIn() );

        }
    }).done(function(data){
        form_status.html('<p class="text-success"> Gracias por la consulta, a la brevedad estaremos respondiendo</p>').delay(3000).fadeOut();
             //clear all fields
            $('#main-contact-form').trigger("reset");
    });
});

2nd: The tag id"name" id"email" id"XX" in mi Form in my case

    $success = @mail($email_to, $subject, $body, 'From: <'.$email_from.'>');

     //to Replace This

    $header  .= 'MIME-Version: 1.0' . "\r\n";
    $header .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    $success = @mail($email_to, $subject, $body, 'From: <'.$email_from.'>',,$header);
 if( $success == true )  
               { 
//success Message
}
else{
//Error Message
}
