The yii error prompt location is under the "@app/views/site/error.php" path, and the default error, the error prompt action, is handled by the error action under the site controller.
Yii2 Modify the error prompt page style
yii2 The default error action is by default under the site controller error action to handle, the corresponding error view page is @app/views/site/error.php page.
return [ ....其它配置 'components' => [ ...其它配置 'errorHandler' => [ 'errorAction' => 'site/error', ], ] ]
The actions() method is rewritten in siteController, and the specified error action is from yii\web\ErrorAction Processing, by default the error view page error.php will inherit the layout file. We can modify the layout file of the error.php page by modifying the actions() method. At the same time, in order to set its error action for each controller, you can define a base The class BaseController inherits yii\web\Controller, and then other controllers inherit the base class, and override the actions method in the base class as follows:
public function actions() { return [ 'error' => [ 'class' => 'yii\web\ErrorAction', 'layout' => false, ], ]; }
class specifies the class that handles error information. When an error action occurs, yii \web\ErrorAction class takes over, layout specifies the error display page using the layout file, view the source code:
Return error message name (error name, such as 404), message (Simple information), exception (error object)

The Yii framework is suitable for developing web applications of all sizes, and its advantages lie in its high performance and rich feature set. 1) Yii adopts an MVC architecture, and its core components include ActiveRecord, Widget and Gii tools. 2) Through the request processing process, Yii efficiently handles HTTP requests. 3) Basic usage shows a simple example of creating controllers and views. 4) Advanced usage demonstrates the flexibility of database operations through ActiveRecord. 5) Debugging skills include using the debug toolbar and logging system. 6) Performance optimization It is recommended to use cache and database query optimization, follow coding specifications and dependency injection to improve code quality.

In Yii2, there are two main ways to display error prompts. One is to use Yii::$app->errorHandler->exception() to automatically catch and display errors when an exception occurs. The other is to use $this->addError(), which displays an error when model validation fails and can be accessed in the view through $model->getErrors(). In the view, you can use if ($errors = $model->getErrors())
