__get()

Returns the value of a component property.

This method will check in the following order and act accordingly:

• a property defined by a getter: return the getter result
• a property of a behavior: return the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $component->property;.

View source

Arguments

• $name (string) – The property name

Returns

mixed – The property value or the value of a behavior's property

Throws

• yii\base\UnknownPropertyException
  if the property is not defined
• yii\base\InvalidCallException
  if the property is write-only.

__isset()

Checks if a property is set, i.e. defined and not null.

This method will check in the following order and act accordingly:

• a property defined by a setter: return whether the property is set
• a property of a behavior: return whether the property is set
• return false for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($component->property).

View source

Arguments

• $name (string) – The property name or the event name

Returns

boolean – Whether the named property is set

__set()

Sets the value of a component property.

This method will check in the following order and act accordingly:

• a property defined by a setter: set the property value
• an event in the format of "on xyz": attach the handler to the event "xyz"
• a behavior in the format of "as xyz": attach the behavior named as "xyz"
• a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $component->property = $value;.

View source

Arguments

• $name (string) – The property name or the event name
• $value (mixed) – The property value

Throws

• yii\base\UnknownPropertyException
  if the property is not defined
• yii\base\InvalidCallException
  if the property is read-only.

actions()

Declares external actions for the controller.

This method is meant to be overwritten to declare external actions for the controller. It should return an array, with array keys being action IDs, and array values the corresponding action class names or action configuration arrays. For example,

return [
    'action1' => 'app\components\Action1',
    'action2' => [
        'class' => 'app\components\Action2',
        'property1' => 'value1',
        'property2' => 'value2',
    ],
];

\Yii::createObject() will be used later to create the requested action using the configuration provided here.

View source

Returns

array

beforeAction()

This method is invoked right before an action is executed.

The method will trigger the EVENT_BEFORE_ACTION event. The return value of the method will determine whether the action should continue to run.

In case the action should not run, the request should be handled inside of the beforeAction code by either providing the necessary output or redirecting the request. Otherwise the response will be empty.

If you override this method, your code should look like the following:

public function beforeAction($action)
{
    // your custom code here, if you want the code to run before action filters,
    // which are triggered on the [EVENT_BEFORE_ACTION](https://www.yiiframework.com/doc/api/2.0/yii-base-controller#EVENT_BEFORE_ACTION-detail) event, e.g. PageCache or AccessControl

    if (!parent::beforeAction($action)) {
        return false;
    }

    // other custom code here

    return true; // or false to not run the action
}

View source

Arguments

• $action (yii\base\Action) – The action to be executed.

Returns

boolean – Whether the action should continue to run.

getActionArgsHelp()

Returns the help information for the anonymous arguments for the action.

The returned value should be an array. The keys are the argument names, and the values are the corresponding help information. Each value must be an array of the following structure:

• required: bool, whether this argument is required
• type: string|null, the PHP type(s) of this argument
• default: mixed, the default value of this argument
• comment: string, the description of this argument

The default implementation will return the help information extracted from the Reflection or DocBlock of the parameters corresponding to the action method.

View source

Arguments

• $action (yii\base\Action) – The action instance

Returns

array – The help information of the action arguments

getActionHelp()

Returns the detailed help information for the specified action.

View source

Arguments

View source

Arguments

• $action (yii\base\Action) – Action to get summary for

Returns

string – A one-line short summary describing the specified action.

getActionOptionsHelp()

Returns the help information for the options for the action.

The returned value should be an array. The keys are the option names, and the values are the corresponding help information. Each value must be an array of the following structure:

• type: string, the PHP type of this argument.
• default: string, the default value of this argument
• comment: string, the comment of this argument

The default implementation will return the help information extracted from the doc-comment of the properties corresponding to the action options.

View source

Arguments

• $action (yii\base\Action)

Returns

array – The help information of the action options

init()

Initializes the object.

This method is invoked at the end of the constructor after the object is initialized with the given configuration.

View source

Throws

• yii\base\InvalidConfigException

options()

Returns the names of valid options for the action (id) An option requires the existence of a public member variable whose name is the option name.

Child classes may override this method to specify possible options.

Note that the values setting via options are not available until beforeAction() is being called.

View source

Arguments

• $actionID (string) – The action id of the current request

Returns

string[] – The names of the options valid for the action

passwordPrompt()

Since

3.6.0

Prompts the user for a password and validates it.

View source

Arguments

• $options (array) – Options to customize the behavior of the prompt:

• label: the prompt label

• required: whether it is required or not (true by default)

• validator: a callable function to validate input. The function must accept two parameters:

  • $input: the user input to validate
  • $error: the error value passed by reference if validation failed

• error: the error message to show if the password is invalid

• confirm: whether the user should be prompted for the password a second time to confirm their input (true by default)

An example of how to use the prompt method with a validator function.

$code = $this->passwordPrompt('Enter 4-Chars-Pin', ['required' => true, 'validator' => function($input, &$error) {
    if (strlen($input) !== 4) {
        $error = 'The Pin must be exactly 4 chars!';
        return false;
    }
    return true;
}]);

Returns

string – The user input

run()

Runs a request specified in terms of a route.

The route can be either an ID of an action within this controller or a complete route consisting of module IDs, controller ID and action ID. If the route starts with a slash '/', the parsing of the route will start from the application; otherwise, it will start from the parent module of this controller.

View source

Arguments

• $route (string) – The route to be handled, e.g., 'view', 'comment/view', '/admin/comment/view'.
• $params (array) – The parameters to be passed to the action.
