How do you use Yii’s “Model Scenarios” for different user inputs?

How do you use Yii’s “Model Scenarios” for different user inputs?

Answer: In Yii, you can use model scenarios to handle different user inputs by defining scenarios in your model class. Each scenario can specify which attributes are required, which validation rules to apply, and how the model behaves depending on the context.

1. Define Scenarios: In your model, override the `scenarios()` method to define different scenarios as keys with their corresponding attributes.

2. Set Scenario: Use `$model->scenario = ‘scenarioName’;` to set the desired scenario based on user input.

3. Validate and Process: When validating, Yii checks the rules specified for the active scenario. You can customize behaviors or validation rules to fit different user contexts.

This allows you to effectively manage different workflows or user inputs in your application.
