DB Schema Management is a class that can be used to: extract a database schema into a PHP script that defines the schema in an array; apply the extracted script to recreate the database schema; allow the editing of the extracted script to implement changes to the schema; and allow users of the application to create changes to the schema that are separate to the extracted script. It has support for pre- and post-processing scripts. It can require a minimum schema version to apply the update.
Form Validation validates form inputs according to a CSS class. It uses the jQuery library to traverse the list of inputs of a form and performs validations of types defined in a CSS class attribute of each input. It supports validations of these types: required, email, date, time currency, numeric, alphanumeric, alphabetic, state, zip code, and URL. If the fields are invalid, an error message is displayed inside a page element for displaying validation errors.
