Get data from custom taxonomy

[David De Laet]

Hi,

We created an hierarchical custom taxonomy.
For example Apple -> IPhone -> IPhone XS
We have 3 select fields where the parent – child of a parent and a child of a child of that parent should be pulled in those select boxes. Can you advise how we get the child of a parent in a select field? Also the child of a child of that parent in a select.

Thanks in advance

Regards,
David

I believe this has to be done via hook. Basically have 3 select fields:

field 1 rows:
value | id

field 2 rows:
value | id | parentid

field 3 rows:
value | id | parentid

Then you have to prefill these 3 fields via hook and for fields 2+3 you have to have cascading logic:
in field 3 show entries which have parentid = field2_id
in field 2 show entries which have parentid = field1_id

I think there is no other way to achieve this.
