Use this snippet to convert legacy field groups from PHP to ACF-JSON files
I was working on a legacy project recently that had a multiple Advanced Custom Fields – field groups registered with PHP. It was difficult to edit these hard coded field groups so I decided it was best to switch these to JSON. I ran the snippet below once, it converts each of the field groups from PHP into JSON and save these JSON files to the acf-json directory.
<?php
// Get all the local field groups and loop through them for processing.
$field_groups = acf_get_local_field_groups();
foreach ( $field_groupsas$group ) {
// If the field group has fields, load them into the 'fields' key.
