Top Posts & Pages widget (Jetpack) questions

1: if there’s a code snippet for making the widget ignore posts which don’t have images.

You could use the jetpack_widget_get_top_posts filter to remove all posts without an image, like so:

/**
 * Remove posts without an image from the Top Posts widget.
 *
 * @param array $posts Array of the most popular posts.
 * @param array $post_ids Array of Post IDs.
 * @param string $count Number of Top Posts we want to display.
 */
function jeherve_skip_posts_without_image( $posts, $post_ids, $count ) {
	foreach ( $posts as $k => $post ) {
		// First, we'll look for an image for our post ID.
		$image = Jetpack_PostImages::get_image( $post['post_id'], array( 'fallback_to_avatars' => false ) );

		// Remove the post if no image exists for that post.
		if ( ! is_array( $image ) ) {
			unset( $posts[ $k ] );
		}
	}
	return $posts;
}
add_filter( 'jetpack_widget_get_top_posts', 'jeherve_skip_posts_without_image' );

if there’s a way to make the widget display random posts in the same style

You could use that same filter again, and return a random list of posts instead of the popular posts.

I hope this helps.

Thank you – your code snippet works fine to remove posts without images.

Sorry but can you tell me how, please? My grey-matter isn’t firing on all neurons like it used to.

Something like this should help:

I added comments so you can understand how the list of Top Posts was replaced by a list of random posts that all include an image.

That’s brilliant, Jeremy, thank you!
