YI framework usage tutorial

getting Started

YI is a fast, scalable MVC framework based on PHP. It provides a powerful set of features that can be used to build a variety of web applications.

Install

  1. Download the latest YI version.
  2. Unzip and move to your web server folder.
  3. Create a database and import sample data.
  4. Configure the database connection information in the settings.php file.

Model, View, Controller (MVC)

YI adopts the MVC architecture:

  • Model: The data layer representing the application.
  • View: Responsible for rendering the user interface.
  • Controller: Connects models and views and processes user input.

routing

YI Use the URL routing system to map URLs to controllers and operations. For example, http://example.com/post/create will map to the create operation of PostController .

Database operations

YI integrates an ActiveRecord mode that simplifies database operations. You just need to define the model class and use save() , find() and other methods for database interaction.

Form processing

YI provides form validation and processing support. You can easily define and validate form fields using FormModel class.

Extended

YI can be extended by creating custom modules. Modules allow you to add new features or modify existing features, such as:

  • Add a new controller or model
  • Integrated third-party library
  • Create custom widgets

Example

Here is an example of creating a simple blog application:

 <code class="php">// 模型class Post extends \yii\db\ActiveRecord { } // 控制器class PostController extends \yii\web\Controller { public function actionCreate() { $post = new Post(); if ($post->load(Yii::$app->request->post()) && $post->save()) { return $this->redirect(['index']); } return $this->render('create', ['post' => $post]); } } // 視圖echo $this->render('post/create', ['post' => $post]);</code>

How do I render a view from a controller? How do I render a view from a controller? Jul 07, 2025 am 12:09 AM

In the MVC framework, the mechanism for the controller to render views is based on the naming convention and allows explicit overwriting. If redirection is not explicitly indicated, the controller will automatically find a view file with the same name as the action for rendering. 1. Make sure that the view file exists and is named correctly. For example, the view path corresponding to the action show of the controller PostsController should be views/posts/show.html.erb or Views/Posts/Show.cshtml; 2. Use explicit rendering to specify different templates, such as render'custom_template' in Rails and view('posts.custom_template') in Laravel

How do I save data to the database using Yii models? How do I save data to the database using Yii models? Jul 05, 2025 am 12:36 AM

When saving data to the database in the Yii framework, it is mainly implemented through the ActiveRecord model. 1. Creating a new record requires instantiation of the model, loading the data and verifying it before saving; 2. Updating the record requires querying the existing data before assignment; 3. When using the load() method for batch assignment, security attributes must be marked in rules(); 4. When saving associated data, transactions should be used to ensure consistency. The specific steps include: instantiating the model and filling the data with load(), calling validate() verification, and finally performing save() persistence; when updating, first obtaining records and then assigning values; when sensitive fields are involved, massassignment should be restricted; when saving the associated model, beginTran should be combined

How do I create custom actions in a Yii controller? How do I create custom actions in a Yii controller? Jul 12, 2025 am 12:35 AM

The method of creating custom operations in Yii is to define a common method starting with an action in the controller, optionally accept parameters; then process data, render views, or return JSON as needed; and finally ensure security through access control. The specific steps include: 1. Create a method prefixed with action; 2. Set the method to public; 3. Can receive URL parameters; 4. Process data such as querying the model, processing POST requests, redirecting, etc.; 5. Use AccessControl or manually checking permissions to restrict access. For example, actionProfile($id) can be accessed via /site/profile?id=123 and renders the user profile page. The best practice is
