In the Yii2.x framework, the concept of modules (Modules) was introduced. So what are modules? (Recommended Learning: Yii Framework )
Module is an independent software unit, consisting of models, views, controllers, and other supporting components. The end user can access it In the controller of an installed module, the module is treated as a small application subject. Different from the application subject, the module cannot be deployed separately and must belong to an application subject.
The simple understanding of the above description is that you create a sub-application body in the existing framework, but this sub-application must depend on the main application body of the framework itself and cannot be deployed independently.
Looking at the picture, the performance is relatively straightforward:
The module shown in the red box in the picture is the location of the module, where There is an admin module. (The logo in the picture blocks a very important file at the bottom, Admin.php).
Create and configure modules
The module is organized into a directory called base path. In this directory, there are subdirectories such as controllers, models, and views respectively. Controllers, models, views and other code are very similar to applications. Take my example above as an example:
admin/ Admin.php 模块类文件 config.php 模块配置文件(自行手动创建) controllers/ 包含控制器类文件 models/ 包含模型类文件 views/ 包含控制器视图文件和布局文件
Module class file
Each module has a module class that inherits yii\base\Module, which Class files are placed directly in the module's base path directory and can be loaded automatically. When a module is accessed, a unique instance of the module class is created similar to the application body instance. The module instance is used to help the code within the module share data and components.
