You can use the connectors for simple form saving. The connectors will recognize and automatically execute CRUD operations for the following patterns:
Get data for some record in DB by id
GET: connector.php?action=get&id={some}
Returns: data in 'json'(if you use JSONDataConnector) or 'xml'(if you use DataConnector) format.
Delete data for some record in DB by id
GET: connector.php?action=delete
POST: id={some}
Returns: "true" as string, when an operation is executed correctly.
Update data for some record in DB by id
GET: connector.php?action=delete
POST: id={some}&property_name={value}
Returns: "true" as a string, when operation is executed correctly.
Insert data in DB
GET: connector.php?action=insert
POST: property_name={value}
Returns: "true\n{new id}" as a string when operation is executed correctly.
