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, e.g. 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.
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'>=></font>
<b>array</b> <i>(size=5)</i>
'name' <font color='#888a85'>=></font> <small>string</small> <font color='#cc0000'>'Максим.jpg'</font> <i>(length=16)</i>
'type' <font color='#888a85'>=></font> <small>string</small> <font color='#cc0000'>'image/jpeg'</font> <i>(length=10)</i>
'tmp_name' <font color='#888a85'>=></font> <small>string</small> <font color='#cc0000'>'C:\wamp\tmp\phpE01A.tmp'</font> <i>(length=23)</i>
'error' <font color='#888a85'>=></font> <small>int</small> <font color='#4e9a06'>0</font>
'size' <font color='#888a85'>=></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?
