15675,"Add a ""parent"" criteria to wp_get_object_terms()",mikeschinkel,,"Currently the core function `wp_get_object_terms()` does not allow the developer to filter by the `parent` field in the `wp_term_taxonomy` table. 

I found this limitation while doing a code review on a client's code. I wanted to recommend elimination of direct SQL queries to minimize kittens crying but found that currently it's not possible to limit the results returned by the SQL query to only those taxonomy items with a given parent. 

This patch adds a `parent` option for the `$args` parameter to `wp_get_object_terms()`.  While I was in there I noticed several other things which I added to the patch:

1.) It updates the header documentation to be easier to scan and to fix some of the errors which appear have resulted in code updates without documentation updates.

2.) It adds DISTINCT for all but `'all_with_object_id'==$fields` as per @scribu's suggestion on ticket #11003.

3.) It changes the code so that only one (1) SQL query is run when `'tt_ids'==$fields` instead of running the standard query and then throwing away its results to run the query a second time. '''However, please check my logic to make sure I didn't introduce an unintentional error here.'''

4.) I added an options for `'fields'` of both `'id=>name' and `'id=>term' because I've needed both of those use-cases several times in the past.

FYI, this patch should be considered a superset of #11003.",enhancement,new,normal,Future Release,Taxonomy,3.1,normal,,has-patch,mikeschinkel@…
