I've had a search and I can't see a similar post, so I thought I'd start my own. I have recently discovered and started to use SimplePie to integrate feeds into websites. It's a great tool, and works well.
However, I now want to display just the first image from inside the content of a post with a caption, or short description. This is proving to be somewhat of a challenge for my naive brain.
Here's my code:
//get the simplepie library require_once('inc/simplepie.inc'); //grab the feed $feed = new SimplePie('http://ameenakaracallender.blogspot.com'); //enable caching $feed->enable_cache(true); //provide the caching folder $feed->set_cache_location('cache'); //set the amount of seconds you want to cache the feed $feed->set_cache_duration(1800); //init the process $feed->init(); //let simplepie handle the content type (atom, RSS...) $feed->handle_content_type();

<h1>Ameena's Blog</h1> <?php foreach ($feed->get_items() as $item): ?> <h2><?php echo $item->get_title(); ?></h2> <h4><?php echo $item->get_date(); ?></h4> <?php echo '<img src="' .$item->get_first_image_url(). '"/>'; ?> <?php endforeach; ?>
The get_first_image_url command, is obviously pseudocode, and I have no idea how to create that function, but essentially that's what I need.
Any help would be great.
Many thanks in advance,
