save_resource_data()
Description
Save resource dataIMPORTANT: inactive nodes should be left alone (don't add/remove) except when processing fixed list field types that
only hold one value (dropdown, radio). Plugins should determine this based on their use cases when hooking.
Parameters
| Column | Type | Default | Description |
|---|---|---|---|
| $ref | int | ||
| $multi | bool | ||
| $autosave_field | string|int | "" |
Return
| true|array | List of errors if unsuccessful, true otherwise |
