How to display non-hierarchical taxonomy as terms with checkboxes?
I’m not sure, if you already found a solution for this, but when I searched for a similar one yesterday, I found this tutorial on WPtuts very helpful. It uses radio buttons, but you can easily modify it to get it working with checkboxes as well. http://wp.tutsplus.com/tutorials/creative-coding/how-to-use-radio-buttons-with-taxonomies/
How to Check if a Page Exists by URL?
You could make a list of paths to check… $page_paths = array( ‘analysis/firstNamelastName’, ‘exercise/firstNamelastName’ ); Then check if there’s a page object for each of the page paths. foreach( $page_paths as $page_path ) { echo ‘<code>’ . $page_path . ‘</code> ‘ . PHP_EOL; if( ! $page = get_page_by_path( $page_path ) ){ echo ‘Does not exist.’ … Read more
Change custom post type to hierarchical after being registered

Nested custom post types with permalinks
If you want to keep ‘authors’ as the base slug in the permalinks, i.e. example.com/authors/stephen-king/ for the ‘authors’ CPT, example.com/authors/stephen-king/the-shining/ for the ‘books’ CPT and example.com/authors/stephen-king/the-shining/chapter-3/ for the ‘chapters’ CPT, WordPress will think pretty much everything is an ‘authors’ post or a hierarchical child of an ‘authors’ post and, since that is not the case, … Read more

How can I allow commas in tag names?
No core hacking needed — thanks to: HOOKS. Hooks allow to fix the issue with a nice combination of a filter replacing “–” by “, ” before output and an “if” block to make sure the output is not also filtered for the admin interface 🙂 and finally, saving all your tags with comma in … Read more
Get the the top-level parent of a custom taxonomy term
Thanks to Ivaylo for this code, which was based on Bainternet’s answer. The first function below, get_term_top_most_parent, accepts a term and taxonomy and returns the the term’s top-level parent (or the term itself, if it’s parentless); the second function (get_top_parents) works in the loop, and, given a taxonomy, returns an HTML list of the top-level … Read more
