获取发布文件的文件大小不起作用

Question

I am sending a file using ajax to a PHP file. All things go OK but the size.

the jquery :

<script>
$('#submitshout').click(function () {
    $('.shoutinputhover').show();
    var formDatashout = new FormData($('#shoutform')[0]);
    $.ajax({
        url: "../pages/sn/ajax/submitshout.php",
        type: "POST",
        data: formDatashout,
        success: function (msg) {
            alert(msg);
            if (msg == 'update') {
                addshout();
            }
        },
        cache: false,
        contentType: false,
        processData: false
    });
   });
</script>

HTML:

    <form method="post" enctype="multipart/form-data" id="shoutform" >
    <textarea  class="ordinaryinput" style="width: 100%;height: 60px" id="shouttxtarea" name="shouttxtarea"></textarea>
    <div class="shoutaddimage">
    <input type="file" name="shoutaddimageer"  id="shoutaddimageer"  style="width: 100%"   >
    </div>
    </form>

and PHP file:

session_start();
error_reporting(E_ERROR);
header('Content-Type: text/plain; charset=utf-8'); 

require '../../../elements/config.php' ;

// get image
die($_FILES["shoutaddimageer"]["size"]);

If I place name or type instead of size in above php code it will return file type or file name accurately but it does not work with size and it returns nothing!!!!

Since I can get file type and file name it means that sending form is going ok . but whats wrong with the size ??

Answer 1

If your file upload is aborted for any reason then have no size.
Check what will return: $_FILES['shoutaddimageer']['error']
