I would like to add more custom batch widget, so how to set custom html helpers to the JHtml class

Question

I know I will have to update the model $batch_commands array and also add the new methods/commands I want to run beyond the normal. But this questions main focus is to add more fields/widgets the batch modal like those in the abstract class JHtmlBatch. So I can use <?php echo JHtml::_('batch.customfield'); ?> in the default_batch.php file.

Okay I found the way that this can be done. In the helpers folder of you component you create a new folder called html and in it you place your file. Now using <?php echo JHtml::_('widget.customfield'); ?> as our example the file name will be admin/helpers/html/widget.php then in the file you add the following:

<?php

defined('_JEXEC') or die;

/**
 * Content HTML helper
 *
 * @since  3.0
 */
abstract class JHtmlWidget
{
    public static function customfield()
    {
        $html = '<h1>works</h1>';

        return $html;
    }
}

Then update this file views/customviewname/tmpl/default.php by adding the following php

JHtml::addIncludePath(JPATH_COMPONENT . '/helpers/html');

Then in the html area you can now declare the widget simply with the following

<?php echo JHtml::_('widget.customfield'); ?>

have fun...
