uploading both data and files in one form using ajax?

I want to implement a simple file upload in my intranet-page, with the smallest setup possible.

This is my HTML part:

<input id="sortpicture" type="file" name="sortpic" />
<button id="upload">Upload</button>

and this is my JS jquery script:

$("#upload").on("click", function() {
    var file_data = $("#sortpicture").prop("files")[0];   
    var form_data = new FormData();
    form_data.append("file", file_data);
        url: "/uploads",
        dataType: 'script',
        cache: false,
        contentType: false,
        processData: false,
        data: form_data,                         
        type: 'post',
        success: function(){

There is a folder named "uploads" in the root directory of the website, with change permissions for "users" and "IIS_users".

When I select a file with the file-form and press the upload button, the first alert returns "[object FormData]". the second alert doesn't get called and the"uploads" folder is empty too!?

Can someone help my finding out whats wrong?

Also the next step should be, to rename the file with a server side generated name. Maybe someone can give me a solution for this, too.

You need a script that runs on the server to move the file to the uploads directory. The jQuery ajax method (running in the browser) sends the form data to the server, then a script on the server handles the upload. Here's an example using PHP.

Your HTML is fine, but update your JS jQuery script to look like this:

$('#upload').on('click', function() {
    var file_data = $('#sortpicture').prop('files')[0];   
    var form_data = new FormData();                  
    form_data.append('file', file_data);
        url: 'upload.php', // point to server-side PHP script 
        dataType: 'text',  // what to expect back from the PHP script, if anything
        cache: false,
        contentType: false,
        processData: false,
        data: form_data,                         
        type: 'post',
        success: function(php_script_response){
            alert(php_script_response); // display response from the PHP script, if any

And now for the server-side script, using PHP in this case.

upload.php: a PHP script that runs on the server and directs the file to the uploads directory:


    if ( 0 < $_FILES['file']['error'] ) {
        echo 'Error: ' . $_FILES['file']['error'] . '<br>';
    else {
        move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);


Also, a couple things about the destination directory:

  1. Make sure you have the correct server path, i.e., starting at the PHP script location what is the path to the uploads directory, and
  2. Make sure it's writeable.

And a little bit about the PHP function move_uploaded_file, used in the upload.php script:


    // this is where the file is temporarily stored on the server when uploaded
    // do not change this

    // this is where you want to put the file and what you want to name it
    // in this case we are putting in a directory called "uploads"
    // and giving it the original filename
    'uploads/' . $_FILES['file']['name']

$_FILES['file']['name'] is the name of the file as it is uploaded. You don't have to use that. You can give the file any name (server filesystem compatible) you want:


And finally, be aware of your PHP upload_max_filesize AND post_max_size configuration values, and be sure your test files do not exceed either. Here's some help how you check PHP configuration and how you set max filesize and post settings.

  • Please read this first : stackoverflow.com/questions/166221/…
  • Everything works for me, maybe it's your PHP code?
  • there is nothing else "connected" with this form. what do you mean with my php code?
  • What I mean is, your code works, maybe the problem is in your server side code.
  • Are you getting an 500 error code upon executing the AJAX script? That would indicate that it is a server side error. Also: make sure that while debugging, you output the PHP file's response to the console. That way, if your PHP code throws an error, you know what's going on.
  • hey BloodyKnuckles! thanks, i think this was one big thing, i misunderstood. So i added the php file, and now i am a little closer. The second alert also pops up! but the folder is still empty.
  • Ah, the form input name "sortpic" is changed to "file" in the form_data.append function. So I changed the PHP script to reflect the new form input name. I also pulled the PHP script response into the ajax success alert to help with debugging.
  • Buddy, it give me error undefined index file at $_FILES['file']
  • @partho , the code prop('files')[0] accesses the local file intended for upload to the server. If you need more explanation look up jQuery function "prop" and "html5 file upload".
  • I resolved this issue.The reason for it was the filesize was too large.
  • What is the if (true) doing? Is always evaluating to true, so is useless, isn't it? Also you have an extra end-curly.
  • I fixed it for you. :)
