Display Images in rss Feeds
-
Using WordPress rss code.
Problem is how to show images from feeds when available.
Code below works but could find nothing that succinctly shows how to display images from feeds, not featured images from posts on own site.
Need code that works for this.<?php if(function_exists('fetch_feed')) { include_once(ABSPATH . WPINC . '/feed.php'); // the file to rss feed generator $feed = fetch_feed('https://anyfeed.com'); // specify the rss feed $limit = $feed->get_item_quantity(6); // specify number of items $items = $feed->get_items(0, $limit); // create an array of items } if ($limit == 0) echo '<div>The feed is either empty or unavailable.</div>'; else foreach ($items as $item) : ?> <FONT FACE='Georgia,serif' SIZE="2" COLOR="#000000"><b> <a href="<?php echo $item->get_permalink(); ?>" alt="<?php echo $item->get_title(); ?>"><?php echo $item->get_title(); ?></a></b></FONT> <FONT COLOR="#000000"><i><?php echo $item->get_date('j F Y @ g:i a'); ?></i> <p><?php echo substr($item->get_description(), 0, 200); ?> ...</p></FONT> <?php endforeach; ?>

Yeah, I got it now. You didn’t mention external in your OP and since you said your code worked, I didn’t look at it very closely.
The item/post description will generally not contain images unless the feed was customized as mentioned in that Codex page I linked previously. (more on this in a bit) In particular, the default feed will not contain featured images at all unless they are also part of post content. (theme dependent) To display post content, images and all, output $item->get_content().
If you want to only display post images from content, without the text, search through the returned content string for
tags. Use preg_search() to be able to extract all the full tags into $matches, then step through the array and output each match/img tag.
There’s an alternate method of customizing your feed to contain featured images. You can use the “the_excerpt_rss” filter to inject featured images into the excerpt. Something like this:
function featured_to_RSS( $excerpt ) { global $post; if ( has_post_thumbnail( $post->ID ) ){ $excerpt = '<div>' . get_the_post_thumbnail( $post->ID, 'medium') . '</div>' . $excerpt; } return $excerpt; } add_filter('the_excerpt_rss', 'featured_to_RSS');With this your current code will include featured images in the output, if they exist. For completeness, you may want to also use
add_filter('the_content_feed', 'featured_to_RSS');to include the featured image in post content. Your code ignores it, but if it’s in the excerpt, one would expect it to also be in content.
