Added Terms controller to fetch terms by taxonomy or post

Hi,

Thanks for the add on.

Could You please add the function to get the taxonomies by parent?

e.g parent=0 or parent=1

Thanks,
Alex

You can use get_terms to fetch the children of a term for categories like this:
/api/terms/get_terms/?taxonomy=category&term_args[parent]=my_parent_term_id

If you want all children of a term (sub categories of sub categories) rather than direct children you can use this:
/api/terms/get_terms/?taxonomy=category&term_args[child]=my_parent_term_id

To fetch the parent of a term you can use get_term twice:
/api/terms/get_term/?term_id=my_term_id&taxonomy=category

Then with the parent from the previous term’s data you can call it again:
/api/terms/get_term/?term_id=my_parent_term_id&taxonomy=category

I could add a shortcut such as get_term_parent to only do one call for parents even though there is no equivalent in WordPress’s API if you’d like.

Hi Einkoro,

Thanks for reply. Yes, I got it but there is some problem. I have 16 categories but it only return 3 categories. I

Another example
I have 12 sub categories but it is only return 2. Yes I only have post for those sub categories.

If you add &term_args[hide_empty]=0 do you get the expected number of categories? By default get_terms will hide any terms without posts associated with them.

Thanks Einkoro,

I got the expected result. Great Add On. Save alot of my time.
