I’m working on creating bidirectional term relationship fields. There’s a taxonomy multi-select field called related_terms, and when a term is saved with some relationships selected, I want to update those terms’ related_terms fields to include the saved term’s ID. I’m using update_term_meta() to save the related_terms array.
I have the related term ID array saving correctly to the database; it’s serialized just like terms selected through the interface. But when I refresh the edit term screen for the related term, Select2 isn’t recognizing the selected options. They’re selected correctly in the hidden field, and I can see them flash by in the form before Select2 loads, but then the field appears empty.
Have I missed something involving caching, or do I need to reinitialize Select2…?
Asking the question in public is always the fastest way to find the answer yourself. 😉 This needs some refinement, but setting the $field[‘default_value’] in a acf/load_field hooked function that runs after most other things is working:
