bool
isValid()

Validates the form submission. The criteria for this example are non-empty fields for first and last name.

business()

Business logic method used to process the data that was used after a successful validation. In this example the received data is stored in result and passed on to the view.

protected bool isValid()

Validates the form submission. The criteria for this example are non-empty fields for first and last name.

These are checked using isEmptyPostField() in two separate if-clauses. If a criterion is violated, an entry in errorMessages is created. The array holding these error messages is then added to the parameters of the current view. If no error messages where created, validation is seen as successful.

Return Value

bool Returns true if validation was successful, otherwise false.
