Sitewide Tags – Thumbnails

I’ve tried using the instructions here: http://mu.wordpress.org/forums/topic/18095

I may have done it incorrectly though. First of all, I should’ve indicated that I’ve installed this plugin into the mu-plugins directory.

Second, after I added the code from the link above, I no longer see a plugin settings page like I had before, which makes me think I added the code incorrectly.

So he said:

Just before the switch_to_blog() function within the sitewide_tags_post() function, add this:

$thumbnail_id = get_post_thumbnail_id( $post->ID );
if( $thumbnail_id ) {
$meta = get_post_meta( $thumbnail_id, ‘_wp_attachment_metadata’ );
$source_dir = wp_upload_dir();
foreach( $meta[0][‘sizes’] as $key => $value ) {
$thumbnails[$key] = $source_dir[‘baseurl’] . ‘/’ . substr($meta[0][‘file’], 0, 8) . $value[‘file’];
}
}

So I added it here under “//testing area 1”

if ( $last_blog_id < $c ) {
				wp_die( "Finished importing posts into tags blogs!" );
			}
			//testing area 1
			$thumbnail_id = get_post_thumbnail_id( $post->ID );
if( $thumbnail_id ) {
$meta = get_post_meta( $thumbnail_id, '_wp_attachment_metadata' );
$source_dir = wp_upload_dir();
foreach( $meta[0]['sizes'] as $key => $value ) {
$thumbnails[$key] = $source_dir['baseurl'] . '/' . substr($meta[0]['file'], 0, 8) . $value['file'];
}
}
			switch_to_blog( $c );
			while ( !$finished ) {
				if ( $wpdb->blogid == $tags_blog_id ) { // not the tags blog

Then he says:
And at the end of the if() statement just before the restore_current_blog() function in that same function add this:

if( $thumbnails ) {
foreach( $thumbnails as $key => $value ) {
add_post_meta( $p, $key, $value );
}
}

So I added that code here under “//testing area 2”

switch_to_blog( $c );
			while ( !$finished ) {
				if ( $wpdb->blogid == $tags_blog_id ) { // not the tags blog
					$c++;
					if ( $last_blog_id < $c ) {
						wp_die( "Finished importing posts into tags blogs!" );
					}
					//testing area 2
					if( $thumbnails ) {
foreach( $thumbnails as $key => $value ) {
add_post_meta( $p, $key, $value );
}
}
					restore_current_blog();

And finally, at the end of the if() statement of the //editing an old post portion, add this:

if( $thumbnails ) {
foreach( $thumbnails as $key => $value ) {
delete_post_meta( $global_post->ID, $key );
}
}

Again, I added it under “//testing area 3”

if( $global_post->ID != '' ) {
			$post->ID = $global_post->ID; // editing an old post
			//testing area 3
			if( $thumbnails ) {
foreach( $thumbnails as $key => $value ) {
delete_post_meta( $global_post->ID, $key );
}
}
			foreach( array_keys( $global_meta ) as $key )

I tried to give you a bit of code above and below each area I worked on so you can see if I put it in the right spot. I tried to keep it short, but sometimes you just have to rock the Cmd+C / Cmd+V am I right?

Thanks all

Thank you David. I have my testing area set up here: http://dsnamerica.com/test/.

The thumbnails that are showing are from the context of the main/original site. The thumbnail areas that have a gray box are those being pulled from other subsites like dsnamerica.com/test/minnesota for example. The content of the articles (text) pulls through. I’m just struggling with the thumbnails.

I’ll remove my Cmd+C/Cmd+V techniques and look closer at the theme’s code. With this in mind, that my original site’s thumbnails work, do you have any other suggestions I could try?

I’ll try what I know and post back here again if it doesn’t work.

I appreciate the help.
