Yii2 Framework extension to provide functionality for consuming RSS and Atom feeds using zend-feed library.
Installation
{
"require":
{
"yurkinx/yii2-rss": "dev-master"
}
}
Configuration
In config file
/config/web.php
Add feed component
'components' => array(
...
'feed' => array(
'class' => 'yii\feed\FeedDriver',
),
)
Simple usage
Read Rss feed:
$feed=Yii::$app->feed->reader()->import('http://exapmple.com/feed.rss');
This will get RSS feed, parse it and return feed object. For more details you can read the official Zend-feed extention documentaion: http://framework.zend.com/manual/2.2/en/modules/zend.feed.reader.html
Create Rss feed:
Create action Rss in controller
public function actionRss(){ $feed=Yii::$app->feed->writer(); $feed->setTitle(Yii::$app->params['title']); $feed->setLink('http://example.com'); $feed->setFeedLink('http://example.com/rss', 'rss'); $feed->setDescription(Yii::t('app','Recent headlines')); $feed->setGenerator('http://example.com/rss'); $feed->setDateModified(time()); /** * Add one or more entries. Note that entries must * be manually added once created. */ $posts=Post::find()->orderBy('id DESC')->limit(20)->all(); foreach($posts as $post){ $entry = $feed->createEntry(); $entry->setTitle($post->title); $entry->setLink(Yii::$app->urlManager->createAbsoluteUrl('/post/view',['id'=>$post->id])); $entry->setDateModified(intval($post->created)); $entry->setDateCreated(intval($post->created)); $entry->setContent( $post->content ); $entry->setEnclosure( [ 'uri'=>$post->image, 'type'=>'image/jpeg', 'length'=>filesize(Yii::getAlias('@webroot').$post->image) ] ); $feed->addEntry($entry); } /** * Render the resulting feed to Atom 1.0 and assign to $out. * You can substitute "atom" with "rss" to generate an RSS 2.0 feed. */ $out = $feed->export('rss'); header('Content-type: text/xml'); echo $out; die(); }
Then it's better to cache it with cache component:
public function behaviors() { return [ .... 'cache'=> [ 'only'=>['rss'], 'class'=>PageCache::className(), 'duration'=>0, 'dependency'=>[ 'class' => 'yii\caching\DbDependency', 'sql' => 'SELECT max(time_updated) as max FROM tbl_post', ], ] ]; }
Take a look at Zend-feed writer official documentaion for more advanced usage of Zend-feed http://framework.zend.com/manual/2.2/en/modules/zend.feed.writer.html
