validate() public method
Performs the data validation.
This method executes the validation rules applicable to the current $scenario. The following criteria are used to determine whether a rule is currently applicable:
- the rule must be associated with the attributes relevant to the current scenario;
- the rules must be effective for the current scenario.
This method will call beforeValidate() and afterValidate() before and after the actual validation, respectively. If beforeValidate() returns false, the validation will be cancelled and afterValidate() will not be called.
Errors found during the validation can be retrieved via getErrors(), getFirstErrors() and getFirstError().
