Bootstrap File Input Demo

Thankful to Krajee!
to get more out of us.

Synchronous Without Preview: This scenario extends scenario 10 for synchronous AJAX based uploads without preview. The events to use are a bit different here (e.g. filebatchuploadsuccess instead of fileuploaded). You would set showPreview to false to disable preview. The progress bar for uploads will by default be shown automatically. To allow trapping and display errors when not having a preview pane, set a custom error container via elErrorContainer. Note that it is recommended to set a display:none style for the error container to have a consistent layout display even when no validation errors exist.


<div class="file-loading">
    <input id="input-710" name="kartik-input-710[]" type="file" multiple>
<div id="kv-error-2" style="margin-top:10px;display:none"></div>
<div id="kv-success-2" class="alert alert-success" style="margin-top:10px;display:none"></div>
$(document).on("ready", function() {
        uploadUrl: "/file-upload-batch/1",
        uploadAsync: false,
        showPreview: false,
        allowedFileExtensions: ['jpg', 'png', 'gif'],
        maxFileCount: 5,
        elErrorContainer: '#kv-error-2'
    }).on('filebatchpreupload', function(event, data, id, index) {
        $('#kv-success-2').html('<h4>Upload Status</h4><ul></ul>').hide();
    }).on('filebatchuploadsuccess', function(event, data) {
        var out = '';
        $.each(data.files, function(key, file) {
            var fname =;
            out = out + '<li>' + 'Uploaded file # ' + (key + 1) + ' - '  +  fname + ' successfully.' + '</li>';
        $('#kv-success-2 ul').append(out);
