Help: Set Featured Image

    I’m using the code below in my theme:
    <?php if ( has_post_thumbnail() ) { the_post_thumbnail('homepage-thumb'); } ?>

    The issue is I’ve just made this theme update, but it only works if in the post itself it has a featured image set. I’d like to show a ‘homepage-thumb’ from the post, even if the featured image hasn’t explicitly been set.

    Toward the bottom of that writeup is a plugin for displaying other images as featured image

    thanks Rev. I’ve modified my code to this so far….

    <?php
if ( has_post_thumbnail() ) {
	the_post_thumbnail('homepage-thumb');
} else {
	// get the ID for an attachment for this post
	$thumb = $wpdb->get_row("SELECT ID, post_title
		FROM {$wpdb->posts}
		WHERE post_parent = {$post->ID}
		AND post_mime_type LIKE 'image%'
		ORDER BY menu_order LIMIT 1");

	if (! empty($thumb)) {
		echo wp_get_attachment_image($thumb->ID, 'homepage-thumb');
	}
}
?>

    After reading the codex, this might be better.

    if ( has_post_thumbnail() ) {
	the_post_thumbnail('homepage-thumb');
} else {
	$args = array( 'post_type' => 'attachment', 'post_parent' => $post->ID, 'order_by' => 'menu_order', 'order' => 'ASC' );
	$attachments = get_posts($args);
	if ($attachments) {
		// display just the first attachment result
		echo wp_get_attachment_image($attachments[0]->ID, 'homepage-thumb');
	}
}
