Method to count all current select files

[fabioaccetta]

I'm using only ajax for upload and delete and I need a method to count all current selected files (both uploadable/deleteable and already uploaded but without errors). Upload is triggered with the filebatchselected event right after files are selected.

If I use $input.fileinput("getFileStack") I don't get the value I expect, as documentation says:

[...] This method will not return files [...] which have already been uploaded.

Shortly, I need a method similar to that one you already use to populate initialCaption inside the <div class="file-caption-name"></div> - previewCache.count(self.id) - to update the div#stack-size with the files count after every upload/delete action, but I can't find anything like that in documentation.

My config with yii2:

[...]
'options' => [
    'multiple' => true,
],
'pluginOptions' => [
    'maxFileCount' => 10,
    'previewFileType' => 'any',
    'initialPreviewAsData' => true,
    'initialPreview' => $initialPreview,
    'initialPreviewConfig' => $initialPreviewConfig,
    'overwriteInitial' => false,
    'uploadUrl' => Url::toRoute(['ajax-file-upload', 'id' => $model->id]),
    'uploadAsync' => false,
],
'pluginEvents' => [
    'filebatchselected' => 'function() {
        $(this).fileinput("upload");
    }',
    'filebatchuploadsuccess' => 'function() {
        var stack = $(this).fileinput("getFileStack"); // <-- not as expected
        var value = stack.length;
        $("#stack-size").html(value);
    }',
    'filedeleted' => 'function() {
        var stack = $(this).fileinput("getFileStack"); // <-- not as expected
        var value = stack.length;
        $("#stack-size").html(value);
    }',
],
[...]

The plugin can only give you client side data... for server side uploaded files - you need to write your logic to calculate the count of files successfully uploaded.

Yes, I need only client side data, exactly like your <div class="file-caption-name"></div> that tells (client-side) the number of files currently handled by the plugin.

[kartik-v]

This is based on validateInitialCount ... but will check on this.... because it can get changed depending on thumbnail delete.... in either case it will only give you the count... the plugin will have no knowledge of data of files on server.

The solution could be a sort of public method like this:

var count = $("#input-id").fileinput("getFilesCount");

available inside the filebatchuploadsuccess and the filedeleted events.
