Integrate into your extension

DPAttachments can be integrated easily into your existing Joomla extension, doesn't matter if it is a component, module or plugin. It takes just three lines of code.

if (JLoader::import('components.com_dpattachments.libraries.dpattachments.core', JPATH_ADMINISTRATOR)) {
    echo DPAttachmentsCore::render('com_demo.item', $object->id);
}

 Write your own plugin

If you are not the developer of a Joomla extension but you want to integrate DPAttachments into it then you can write your own plugin. The only requirement is that the extensions fires an event where the plugin can be an observer of. Have a look at the content plugin of DPAttachements. Basically you need the following code similar to the DPCalendar event plugin:

<?php

defined('_JEXEC') or die();

JLoader::import('components.com_dpattachments.libraries.dpattachments.core', JPATH_ADMINISTRATOR);

// If the component is not installed we fail here and no error is thrown
if (! class_exists('DPAttachmentsCore')) {
    return;
}

class plgDPCalendarDpattachments extends JPlugin {

    public function onEventAfterDisplay($event, $output) {
        return DPAttachmentsCore::render('com_dpcalendar.event', $event->id);
    }

    public function onEventAfterDelete($event) {
        return DPAttachmentsCore::delete('com_dpcalendar.event', $event->id);
    }
}
