Feed Reader Show widget

This widget loads a feed from a url, and displays feed items.
To use it, just drag&drop a Feed Reader/Show widget somewhere on your site.

Options

Configure the widget on the widget edition dialog:
- url Feed url to load.
- nb_items Number of feed items to display.
- life_time Duration of the cache in seconds.

Customize the template

Copy
plugins/dmWidgetFeedReaderPlugin/modules/dmWidget/templates/_dmWidgetFeedReaderShow.php
to
apps/front/modules/dmWidget/templates/_dmWidgetFeedReaderShow.php
then modify it.

Default template:

/*
 * An $item is an array containing:  
 * - title:       title of the feed item  
 * - link:        url of the feed item  
 * - content:     HTML content  
 * - pub_date:    item publication date (timestamp)  
 * - author_name: author name  
 * - author_link: author link  
 * - author_email: author email  
 */  
 
echo _open('ul');  
 
foreach($items as $item)  
{  
  echo _tag('li',  
 
    // link to the feed page  
    _link($item['link'])->text($item['title'])->set('.feed_item_link').  
 
    // render truncated feed content  
    _tag('div.feed_item_content', dmString::truncate(strip_tags($item['content']), 100))  
 
  );  
}  
 
echo _close('ul');  

This template uses Diem template helpers

Filter items with an event

You can modify the list of feed items before they are displayed by listening the dm.widget_twitter_feed_reader_show.items event.

apps/front/frontConfiguration.class.php

class frontConfiguration extends dmFrontApplicationConfiguration
{  
 
  public function configure()  
  {  
    // connect to the dm.widget_feed_reader_show.items event  
    $this->dispatcher->connect('dm.widget_feed_reader_show.items', array($this, 'listenToFeedReaderShowItemsEvent'));  
  }  
 
  public function listenToFeedReaderShowItemsEvent(sfEvent $e, array $items)  
  {  
    // do something with the feed items  
    ...  
    // return the filtered items  
    return $items;  
  }
