The second part of the around method is executed.If the current plugin is the last in the chain, the observed method is executed.If there is another plugin in the chain, all subsequent plugins are wrapped in an independent sequence loop and the execution starts another flow.The around method executes the callable.The first part of the plugin’s around method is executed.Then the current plugin’s around method is called.Magento executes the current plugin’s before method.Before the execution of the observed method, starting from lowest to highest sortOrder.Magento executes plugins using these rules during each plugin execution in two main flows: Check the component load order in app/etc/config.php file. If two or more plugins have the same sortOrder value or do not specify it, the component load order declared in the sequence node from module.xml and area will define the merge sequence. The Magento\Framework\Interception\PluginListInterface which is implemented by Magento\Framework\Interception\PluginList\PluginList is responsible to define when to call the before, around, or after methods respecting this prioritization. The sortOrder property from the plugin node declared in di.xml determines the plugin’s prioritization when more than one plugin is observing the same method. * public function afterLogin ( Auth $authModel, $result, $username ) It is a Magento best practice to capitalize the first letter of the class method name for which you want to create a plugin before adding before, around or after prefixes to it.įor example, to create a plugin for the setName method of some class: The first argument for the before, after, and around methods is an object that provides access to all public methods of the observed method’s class.

The default value is false.īy applying code before, after, or around a public method, a plugin extends or modifies that method’s behavior. To disable a plugin, set this element to true. Plugins that call the same method run them using this order. Use the following naming convention when you specify this element: \Vendor\Module\Plugin\. The name of a plugin’s class or its virtual type. Also used to merge the configurations for the plugin. An arbitrary plugin name that identifies a plugin. A class or interface which the plugin observes. The di.xml file in your module declares a plugin for a class object:

Objects that implement Magento\Framework\ObjectManager\NoninterceptableInterface.

Objects that are instantiated before Magento\Framework\Interception is bootstrapped.

Magento calls these interceptors sequentially according to a configured sort order, so they do not conflict with one another. Your Plugin class implementation changes the behavior of a class function, but it does not change the class itself. This interception approach reduces conflicts among extensions that change the behavior of the same class or method. This allows you to substitute or extend the behavior of original, public methods for any class or interface.Įxtensions that wish to intercept and change the behavior of a public method can create a Plugin class.

Handling outdated in-memory object statesĪ plugin, or interceptor, is a class that modifies the behavior of public class functions by intercepting a function call and running code before, after, or around that function call.
