Ajax Upload image

first in your ajax call include success & error function and then check if it gives you error or what?

your code should be like this

$(document).ready(function (e) {
    $('#imageUploadForm').on('submit',(function(e) {
        e.preventDefault();
        var formData = new FormData(this);

        $.ajax({
            type:'POST',
            url: $(this).attr('action'),
            data:formData,
            cache:false,
            contentType: false,
            processData: false,
            success:function(data){
                console.log("success");
                console.log(data);
            },
            error: function(data){
                console.log("error");
                console.log(data);
            }
        });
    }));

    $("#ImageBrowse").on("change", function() {
        $("#imageUploadForm").submit();
    });
});

Thanks for you help, I change my dynamic about the script so now, it works perfectly with what I have to do.

There is the script for my upload system :

<-- VIEW (upload_img)-->

<div id="container">
<div id="filelist"></div>
<a href="http://localhost:8888/myproject/#" id="userfile" name="userfile">[Select files]      </a>    
<a href="http://localhost:8888/myproject/images/index#" id="uploadfiles">[Upload files]</a
</div>

<-- CONTROLLER -->

function index(){
    if($this->_access())
    {
        $this->template->add_include('js/jquery.js')
                       ->add_include('js/browserplus.js')
                       ->add_include('js/plugins/plupload/plupload.full.js')
                       ->add_include('js/imgfunc.js');
        $this->template->view('upload_img');
    }
    else
    {
        redirect(site_url());
    }
}

function upload_image_spot()
{
    if($query = $this->images_model->upload_image_spot())
    {
        echo json_encode($query);
    }
    else
    {
        echo $this->upload->display_errors('', '');
    }
}

<-- MODEL -->

   function upload_image_spot()
{
    $config['upload_path'] = realpath(APPPATH. '../images/spots');
    $config['allowed_types'] = 'jpg|jpeg|tiff|png';
    $config['max_size'] = 3062;
    $config['encrypt_name'] = TRUE;
    $this->load->library('upload', $config);
    if($this->upload->do_upload('file')) 
    // file means the file send to the website for upload, this is the name of field for Plupload script
    {
    $data_img = $this->upload->data();
    $copies = array(
            array('dir' => 'images/spots/large/', 'x' => 1000, 'y' => 600),
            array('dir' => 'images/spots/thumb/', 'x' => 100, 'y' => 60)
    );

    $this->copies($data_img,$copies);

    return 'whatever'; // Not real data, I don't wanna post them here
    }
}

<-- JS-SCRIPTS -->

First of all include :

-jQuery

-browserPlus

-Plupload

(Plupload Script)

Now add this script in an empty file:

var uploader = new plupload.Uploader({
    runtimes : 'gears,html5,flash,silverlight,browserplus',
    browse_button : 'userfile',
    container : 'container',
    max_file_size : '3mb',
    url : 'yourUploadFunctionCI',
    flash_swf_url : 'plugins/plupload/js/plupload.flash.swf',
    silverlight_xap_url : 'plugins/plupload/js/plupload.silverlight.xap',
    filters : [
        {title : "Image files", extensions : "jpg,jpeg,JPG,JPEG,tiff,png"},
    ]
});

uploader.bind('Init', function(up, params) {
});

$('#uploadfiles').click(function(e) {
    uploader.start();
    e.preventDefault();
});

uploader.init();

uploader.bind('FilesAdded', function(up, files) {
    $.each(files, function(i, file) {
        $('#filelist').html("");
        $('#filelist').append(
            '<div id="' + file.id + '">' +
            file.name + ' (' + plupload.formatSize(file.size) + ') <b></b>' +
        '</div>');
    });

    up.refresh();
});

uploader.bind('UploadProgress', function(up, file) {
    $('#' + file.id + " b").html(file.percent + "%");
});

uploader.bind('Error', function(up, err, msg,file) {
    $('#filelist').append("<div>Error: " + err.code +
        ", Message: " + err.message +
        (err.file ? ", File: " + err.file.name : "") +
        "</div>"
    );
    console.log(msg,up,err);
    up.refresh();
});

uploader.bind('FileUploaded', function(up, file,response) {
    $('#' + file.id + " b").html("100%");
    var data = jQuery.parseJSON(msg.response);
    console.log(data);
});

Do your own customization and that's it, no need extra script like you can see on website like copy/paste all script from a php file to a controller, just add 'file' inside do_upload and everything's gonna work fine !

Have a nice day guys, hope it's help.

you can use following code :

var form = new FormData($('#form_step4')[0]);
form.append('view_type','addtemplate');
$.ajax({
    type: "POST",
    url: "savedata.php",
    data: form,
    cache: false,
    contentType: false,
    processData: false,
    success:  function(data){
        //alert("---"+data);
        alert("Settings has been updated successfully.");
        window.location.reload(true);
    }
});

where savedata.php is the file name in which you can do the the DB things
