Reply To: Automatic Synchronized Json

I needed this, as well, so I just went into the ACF code to see how the sync itself was done. I took out the code to perform the sync and added it to another function and then hooked it to admin_init.

Below is the code, but I must encourage everyone to use at your own risk, as it will run the update regardless if it is “approved” by the user or not.

/**
 * Function that will update ACF fields via JSON file update
 */
function jp_sync_acf_fields() {

	// vars
	$groups = acf_get_field_groups();
	$sync 	= array();

	// bail early if no field groups
	if( empty( $groups ) )
		return;

	// find JSON field groups which have not yet been imported
	foreach( $groups as $group ) {
		
		// vars
		$local 		= acf_maybe_get( $group, 'local', false );
		$modified 	= acf_maybe_get( $group, 'modified', 0 );
		$private 	= acf_maybe_get( $group, 'private', false );
		
		// ignore DB / PHP / private field groups
		if( $local !== 'json' || $private ) {
			
			// do nothing
			
		} elseif( ! $group[ 'ID' ] ) {
			
			$sync[ $group[ 'key' ] ] = $group;
			
		} elseif( $modified && $modified > get_post_modified_time( 'U', true, $group[ 'ID' ], true ) ) {
			
			$sync[ $group[ 'key' ] ]  = $group;
		}
	}

	// bail if no sync needed
	if( empty( $sync ) )
		return;

	if( ! empty( $sync ) ) { //if( ! empty( $keys ) ) {
		
		// vars
		$new_ids = array();
		
		foreach( $sync as $key => $v ) { //foreach( $keys as $key ) {
			
			// append fields
			if( acf_have_local_fields( $key ) ) {
				
				$sync[ $key ][ 'fields' ] = acf_get_local_fields( $key );
				
			}
			// import
			$field_group = acf_import_field_group( $sync[ $key ] );
		}
	}
}
add_action( 'admin_init', 'jp_sync_acf_fields' );
