yii\base\Model::rules PHP Метод

rules() публичный Метод

Validation rules are used by Model::validate to check if attribute values are valid. Child classes may override this method to declare different validation rules. Each rule is an array with the following structure: php [ ['attribute1', 'attribute2'], 'validator type', 'on' => ['scenario1', 'scenario2'], ...other parameters... ] where - attribute list: required, specifies the attributes array to be validated, for single attribute you can pass a string; - validator type: required, specifies the validator to be used. It can be a built-in validator name, a method name of the model class, an anonymous function, or a validator class name. - on: optional, specifies the [[scenario|scenarios]] array in which the validation rule can be applied. If this option is not set, the rule will apply to all scenarios. - additional name-value pairs can be specified to initialize the corresponding validator properties. Please refer to individual validator class API for possible properties. A validator can be either an object of a class extending [[Validator]], or a model class method (called *inline validator*) that has the following signature: php $params refers to validation parameters given in the rule function validatorName($attribute, $params) In the above $attribute refers to the attribute currently being validated while $params contains an array of validator configuration options such as max in case of string validator. The value of the attribute currently being validated can be accessed as $this->$attribute. Note the $ before attribute; this is taking the value of the variable $attribute and using it as the name of the property to access. Yii also provides a set of [[Validator::builtInValidators|built-in validators]]. Each one has an alias name which can be used when specifying a validation rule. Below are some examples: php [ built-in "required" validator [['username', 'password'], 'required'], built-in "string" validator customized with "min" and "max" properties ['username', 'string', 'min' => 3, 'max' => 12], built-in "compare" validator that is used in "register" scenario only ['password', 'compare', 'compareAttribute' => 'password2', 'on' => 'register'], an inline validator defined via the "authenticate()" method in the model class ['password', 'authenticate', 'on' => 'login'], a validator of class "DateRangeValidator" ['dateRange', 'DateRangeValidator'], ]; Note, in order to inherit rules defined in the parent class, a child class needs to merge the parent rules with child rules using functions such as array_merge().
