WordPress Core Weekly

Hi Everyone!

It’s that time again: WordPress CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. Weekly is here. This is a catchup post and covers all commits since the last post up until 11/9/2014.

First, a couple quick notes!

Taxonomies

  • Do not create shared taxonomy terms. [30240] #21950; See #5809.
  • Split shared taxonomy terms during term update. [30238] [30239] [30241] #5809
  • Don’t force child_of=0 for non-hierarchical taxonomies in get_terms(). [30265] #30275
  • In get_adjacent_post(), $excluded_terms should check term_id rather than term_taxonom_id. [30263] #29663, #22112.
  • Allow resource_type to be specified in get_ancestors(). Being explicit about resource type (taxonomy vs post_type) allows for the proper resolution of conflicts when a taxonomy and post_type share a slug. [30141] #15029
  • In wp_insert_term(), clean up accidental duplicate terms after insert. [30238] See #22023, #5809.

  • In in_object_in_term(), only check numeric string values against term_id. [30205] #29467
  • Introduce term_template param to get_the_taxonomies() to allow theme and pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

[30209] See #27238.
  • Allow duplicate slugs across different post types. [30158] #18962
  • In get_terms(), do not override hierarchical and pad_count when parent is present. The previous behavior resulted in descendant terms being improperly excluded from the results when passing a parent, even when hierarchical had been set to true. [30107] #29815
  • Clean up get_term_by() caching, fix cache key/group modification that was missed in [30073], and update unit tests. [30108] #21760
