Javascript Question

No file being uploaded while uploading multiple files using AJAX

I am trying to upload multiple files with only 1 AJAX request. But I am facing some problems and they are:

UPDATE


  • No file is being uploaded to the server

  • It seems to me that multiple AJAX requests are being made as AJAX is inside the for loop.



How to sort these problems?

HTML

<!--<form id="fileupload" method="POST" enctype="multipart/form-data">-->
<input type="file" multiple name="uploadfile[]" id="uploadfile" />
<!--</form>-->


JS

$("#uploadfile").change(function(){
//submit the form here
//$('#fileupload').submit();
var files = $("#uploadfile")[0].files;
for (var i = 0; i < files.length; i++){
//alert(files[i].name);
var data = files[i].name;
$.ajax({
type:'POST',
url: 'mupld.php',
data: data
});
}

//var files = $('#uploadfile').prop("files"); //files will be a FileList object.
//alert(files);
//var names = $.map(files, function(val) { return val.name; }); //names is an array of strings (file names)


});

PHP

<?php
if(isset($_FILES['uploadfile'])){

$errors= array();

foreach($_FILES['uploadfile']['tmp_name'] as $key => $tmp_name ){
$file_name = $key.$_FILES['uploadfile']['name'][$key];
$file_size =$_FILES['uploadfile']['size'][$key];
$file_tmp =$_FILES['uploadfile']['tmp_name'][$key];
$file_type=$_FILES['uploadfile']['type'][$key];
if($file_size > 2097152){
$errors[]='File size must be less than 2 MB';
}

//$query="INSERT into upload_data (`USER_ID`,`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$user_id','$file_name','$file_size','$file_type'); ";

$desired_dir="storage";

if(empty($errors)==true){
if(is_dir($desired_dir)==false){
mkdir("$desired_dir", 0700); // Create directory if it does not exist
}

if(is_dir("$desired_dir/".$file_name)==false){
move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
}
else{ // rename the file if another one exist
$new_dir="$desired_dir/".$file_name.time();
rename($file_tmp,$new_dir) ;
}
//mysql_query($query);
}
else{
print_r($errors);
}
}
if(empty($error)){
echo "Success";
}
}
?>

Answer

js at Question does not appear to upload File object, but File.name at var data = files[i].name; ? <!-- --> is not valid comment in javascript

Try using FormData()

$("#uploadfile").change(function() {
    var files = $("#fileupload")[0];
        $.ajax({
            type:"POST",
            url: "mupld.php",
            data: new FormData(files),
            processData: false,
            contentType: false
        });
});
