Hi @sunilkushwaha01
I’ve just tested the update_field()
function and it was working correctly.
Could you please make sure that the variables you used have the correct value? Also, I suggest you use the field key instead of the field name.
Could you also try to update the field by providing the parameters manually like this:
update_field('field_1234567890abc', 'test', 'taxonomy-slug_99');
Thanks 🙂
