Question

I’ve got a function to add a tag by post ID, but now I would like to delete all the current tags for that ID before adding my new tags?

Does anyone know a built in function or wordpress query to do this?

If you can access the database directly (PhpMyAdmin), the quickest way is a SQL request.

Look at the database schema in the codex :

DELETE FROM wp_term_relationships
WHERE wp_term_relationships.object_id = 'yourPostId'
AND wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id
AND wp_term_taxonomy.taxonomy = 'post_tag';

WARNING : obviously, modifying directly the database is dangerous. Be careful doing that.
