Upload non-latin name file with jQuery

Question

I have simple form to ajax-upload files to server.

Here is input event listener:

$(document).on('change', '.js-file', function(event){

    sendFile(event);
});

And here is the function that actually uploads the file:

function sendFile (event) {
    var files = event.target.files;


    var action = '/ajax-upload-files/';
    var data = new FormData();

    $.each(files, function(key, value)
    {
        data.append(key, value);
    });

    $.ajax({
        url: action,
        type: 'POST',
        data: data,
        cache: false,
        dataType: 'json',
        processData: false,
        contentType: false,
        success: function(data){

        },
        complete: function(data) {
        }
    });
}

It wors fine with all kinds of files, except those with non-latin characters in the file name, eg Максим.jpg

The data is being sent to server, as I see in Chrome network. But when I try to dump $_FILES on server, it seems to be empty.

var_dump($_FILES) //array(0) {}

I don't really understand what's wrong - contentLength of the request header is much smaller then it should be - it looks like file was not appended to form for some reason.

Answer 1

I finally managed to upload non-latin name file. Have to read it as binary and send as binary.

HTML:

<input class="js-file" name="filename" type="file">

And js

//Handler in input
$(document).on('change', '.js-file', function(event){
            var file_name = $(this).attr('name');


            var reader = new FileReader();
            var f = event.target.files[0],
                nameArr = event.target.files[0]['name'].split('.'),
                extension = nameArr[nameArr.length-1]; //here we can check if extension is allowed

            reader.onload = function(e) {
                var contents = e.target.result;
                contents = contents.split('base64,')[1]; //we need only encoded part

                sendFileAsBinary(file_name, extension, contents);
            };

            reader.readAsDataURL(f);


        });

And sender:

function sendFileAsBinary(file_name, extension, img) {

    $.ajax({
        url: '/ajax-upload-files/',
        type: 'POST',
        data: {
            name: file_name,
            img: img,
            extension: extension
        },
        dataType: 'json',
        success: function(data){


        },
        complete: function(data) {

        }

    })

}

And php code to decode image:

 $name = $this->_getParam('name');
 $extension = $this->_getParam('extension');
 $computedName = $name . '.' . $extension;

 $fileContent = base64_decode($this->_getParam('img'));

 file_put_contents($fileContent, $computedName);

here is the code I'm using(your code):

HTML file

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script src="jquery.min.js"></script>
<script>
$(document).on('change', '#fileToUpload', function(event){
    sendFile(event);
});

function sendFile (event) {
    var files = event.target.files;
    var myAction = 'test.php';
    var myData = new FormData();

    $.each(files, function(key, value){
        myData.append(key, value);
    });

    $.ajax({
        url: myAction,
        type: 'POST',
        data: myData,
        cache: false,
//        dataType: 'json',
        processData: false,
        contentType: false,
        success: function(data){
                    console.log(data);
        },
        complete: function(data) {
        }
    });
}
</script>
</head>

<body>

<form action="test.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>

test.php

<?php
echo var_dump($_FILES);
?>

result in console.log()

<pre class='xdebug-var-dump' dir='ltr'>
<b>array</b> <i>(size=1)</i>
  0 <font color='#888a85'>=&gt;</font> 
    <b>array</b> <i>(size=5)</i>
      'name' <font color='#888a85'>=&gt;</font> <small>string</small> <font color='#cc0000'>'Максим.jpg'</font> <i>(length=16)</i>
      'type' <font color='#888a85'>=&gt;</font> <small>string</small> <font color='#cc0000'>'image/jpeg'</font> <i>(length=10)</i>
      'tmp_name' <font color='#888a85'>=&gt;</font> <small>string</small> <font color='#cc0000'>'C:\wamp\tmp\phpE01A.tmp'</font> <i>(length=23)</i>
      'error' <font color='#888a85'>=&gt;</font> <small>int</small> <font color='#4e9a06'>0</font>
      'size' <font color='#888a85'>=&gt;</font> <small>int</small> <font color='#4e9a06'>951214</font>
</pre>

so, as you can see, my code uploads file and server can see it. do you have different results on your machine?
