orphaned taxonomy terms remove by sql query
You shouldn’t need to use a custom SQL query – stick to the built-in method wp_delete_post(). This will also clear out all term relationships too.

Exclude main blog from get_blogs_of_user
If you drop this line in your code, you will see all the properties of $user_blogs. echo ‘<pre>’.print_r($user_blogs,true).'</pre>’; One of them is userblog_id, so you just have to check against it before echoing the blogname. <?php $user_blogs = get_blogs_of_user( $user_id ); if (!$user_blogs) { echo ‘no blogs’; } else { echo ‘<div><ul>’; foreach ( $user_blogs … Read more

YOu can deactive the default tag feature and add via plugin an custom taxonomie, that only list your created tags, like category meta box. Its also possible to design this how the tag meta box.
Edit post meta with checkboxes on front end
My gut instinct would be to roll my own AJAX callback.

An untested example (props to Kailey Lampert): // Add checkboxes … Read more
Add a term to an attachment submitted from front end
media handle sideload returns an attachment ID, and attachments are normal posts with the post type ‘attachment’.

Get the Term List – Ordering
To expand on my comment above, you would replace your code with something like this: print_taxonomy_ranks( get_the_terms( $post->ID, ‘post_tags’ ) ); and in your function print_taxonomy_ranks you’d replace the echo statement with your preferred output. function print_taxonomy_ranks( $terms ) { // if terms is not array or its empty don’t proceed if ( ! is_array( … Read more

Dynamically create/remove terms in taxonomy when custom post type is published/trashed
Ok, I think I’ve figured out a viable solution. Kinda disappointed that there’s no way I’ve found thus far to hook directly into trash_{custom_post_type} like I was able to on the publish_{custom_post_type} hook. Here’s a solution for anyone else struggling with this issue. If anyone has any better suggestions, please feel free to share! /** … Read more
