Here is what I come up with based on your suggestion:
function my_save_json( $path ) {
if( isset($_POST['acf_field_group']['key']) ) {
$paths = my_load_json(array()); // pass in empty array to only get local paths
foreach( $paths as $load_path ) {
// loop over each load path for json files
foreach (glob($load_path . "/*.json") as $filename) {
$field_group = json_decode(file_get_contents($filename), true);
// if the key matches a group in this plugin then return the path
if (is_array($field_group) && $field_group['key'] == $_POST['acf_field_group']['key']) {
return $load_path;
}
}
}
}
// return
return $path;
}
function my_load_json( $paths ) {
$paths[] = MY_PLUGIN_DIR .'fields';
return $paths;
}
This works on next field group save if I move the generated JSON file into my plugin directory.
How does that look to you?
