Embed an RSS Feed

[api:RestfulService] can be used to easily embed an RSS feed from a site. In this How to we'll embed the latest weather information from the Yahoo Weather API.

First, we write the code to query the API feed.

mysite/code/Page.php

:::php
public function getWellingtonWeather() {
	$fetch = new RestfulService(
		'https://query.yahooapis.com/v1/public/yql'
	);
	
	$fetch->setQueryString(array(
		'q' => 'select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="Wellington, NZ")'
	));
	
	// perform the query
	$conn = $fetch->request();

	// parse the XML body
	$msgs = $fetch->getValues($conn->getBody(), "results");

	// generate an object our templates can read
	$output = new ArrayList();

	if($msgs) {
		foreach($msgs as $msg) {
			$output->push(new ArrayData(array(
				'Description' => Convert::xml2raw($msg->channel_item_description)
			)));
		}
	}

	return $output;
}

This will provide our Page template with a new WellingtonWeather variable (an [api:ArrayList]). Each item has a single field Description.

mysite/templates/Page.ss

:::ss
<% if WellingtonWeather %>
<% loop WellingtonWeather %>
	$Description
<% end_loop %>
<% end_if %>
