Laravel MVC: quickstart guide

Laravel MVC: quickstart guide

Laravel was chosen for its elegant syntax, powerful features and MVC architecture. 1) The MVC mode separates data (model), logical flow (controller) and presentation (view), improving the maintainability and scalability of the code. 2) Shows how the model, controller and view work together through code examples. 3) It is recommended to keep the model strong, the controller is concise, and the view focuses on display. 4) Laravel's routing system is flexible and can be mapped directly to the controller. 5) Use preload to optimize query performance to avoid N 1 query problems. 6) Follow the DRY principle, reuse code using Blade templates and EloquentORM to maintain consistency and simplicity.

How to create custom widgets in Yii

How to pass data from controller to view in Yii

How to pass data from controller to view in Yii

The most common way to pass data using the render() method is. In the controller, data is passed through associative arrays, and the key name becomes a variable in the view; 2. Use view->params to share data, such as page title or breadcrumbs in multiple views or layouts; 3. You can directly pass model or object instances, suitable for CRUD operations and integrate well with widgets such as ActiveForm; 4. In Yii3 or advanced mode, you can use view components to encapsulate data logic, but in most cases the render() method is sufficient; the output must always be escaped to prevent XSS, and data should be prepared at the controller or service layer rather than handling complex logic in the view.

How to use the repository pattern in Laravel

How to use the repository pattern in Laravel

Using the warehouse model can effectively separate data access logic in Laravel, 1. Define interfaces and clear contracts; 2. Create an Eloquent implementation class to process database operations; 3. Bind interfaces and implementations in the service provider; 4. Use the warehouse through dependency injection in the controller; 5. Optionally add a cache layer through the decorator to enhance performance; this model is suitable for complex applications that require decoupling and testability, but should not be overused in simple CRUD projects, ultimately improving the maintainability and scalability of the code.

Use the find() method to query data in combination with where, orderBy, limit, etc., such as findOne() to obtain a single record, and all() get multiple; 4. Call save() to insert a new record by instantiating the model and assigning attributes, or save(
