Create a social network website using the Yii framework
Jun 21, 2023 pm 06:19 PM
As an excellent web application framework, Yii is one of the first choices for many developers. Using the Yii framework can help us create a fully functional web application efficiently. In this article, we are going to explore how to create a social networking website using the Yii framework.
1. Select appropriate tools and hosting platforms
Before starting to use the Yii framework, we need to pre-install PHP and MySQL on the computer. In addition, we also need to choose a suitable code editor such as Sublime Text or Atom and use Git for code version control. Finally, we need to consider which hosting platform to use to manage the code. Git and Github, Bitbucket and CodebaseHQ are some of the more popular choices.
2. Install and configure the Yii2 framework
Next, we need to download the Yii2 framework from Yii’s official website. We can extract it to any location on our computer. Next, we need to enter the following code on the command line to install and configure Yii:
php composer.phar global require "fxp/composer-asset-plugin:~1.1.1" php composer.phar create-project yiisoft/yii2-app-basic myproject
The above command will install the Yii2 framework and create a project folder named myproject. Next, we need to use the terminal to enter this folder, which will become our source code directory.
3. Create the database and set up the application
Now, we need to create the database using MySQL. We can use PHPMyAdmin or MySQL command line for database operations. For example, we can enter the following command in the MySQL command line to create a database named mysocialnetwork:
CREATE DATABASE mysocialnetwork;
Then we need to set up the database in the Yii application. Open the config/web.php or config/console.php file to set it up. For example, we can add the following code to these files:
'db' => [
'class' => 'yiidbConnection',
'dsn' => 'mysql:host=localhost;dbname=mysocialnetwork',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
],
Then, we can create a "yiiwebApplication" object using the "Yii::createObject()" method provided by the Yii framework, as shown below:
require(__DIR__ . '/../vendor/autoload.php'); require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php'); $config = require(__DIR__ . '/../config/web.php'); (new yiiwebApplication($config))->run();
This object is the application we created, which will manage the entire project and handle all requests.
4. Create models and controllers
Next, we need to create models and controllers for managing data and processing business logic. In Yii, we can automatically generate these files using the Gii code generator.
First, we need to enter the following code in the command line to start Gii:
php yii gii
Then, we need to follow the prompts and enter the URL in the browser. On this page we can create a new model and controller.
For example, we can create a model named "User" and run the following command:
php yii gii/model --tableName=user --modelClass=User
This will create a model named User.
Next, we can create a controller named "SiteController" and run the following command:
php yii gii/controller --controllerClass=SiteController
This will create a controller named SiteController.
5. Create a view
View is the HTML and CSS code used to present data in a web application. In Yii, we can use some basic widgets, widgets, themes and extensions provided by Yii itself to speed up and simplify the creation and rendering of views.
For example, we can add the following code to the view to use the "ListView" widget provided by Yii:
use yiiwidgetsListView;
<?= ListView::widget([
'dataProvider' => $dataProvider,
'itemView' => '_post',
]) ?>
This will add a subview named "_post" to the view .
6. Testing and Deployment
Now, we have completed creating some basic files and functions using the Yii framework. We can use the built-in server provided by Yii to run the web application directly on the local computer for testing.
Go into our project folder in the terminal and enter the following command to start the web server that comes with Yii:
php yii serve
This will start the web server and start our web on the local computer app.
Finally, we need to deploy our code to the remote server. We can use Git and hosting platforms to manage code updates, and use protocols such as FTP or SSH to upload code to remote servers.
Summary
In this article, we discussed how to use the Yii framework to create a social network website and described the steps and methods in the entire process. In actual applications, we need to design functions and pages based on business logic and user needs. Using the Yii framework can help us develop a fully functional and user-friendly web application quickly and efficiently.
