Create a food website using Yii framework

With the popularization of the Internet, people’s demand and pursuit of delicious food are also increasing. Therefore, how to provide users with high-quality food information and experience has become one of the important issues to be solved by online platforms. This article will introduce how to use the Yii framework to create a food website.

1. Understand the Yii framework

Yii is an open source web application framework based on the PHP language. It is characterized by simplicity, ease of use, efficiency, stability, safety and reliability, and is a mature and reliable web application development tool. Yii's MVC model and powerful caching mechanism enable it to quickly respond to user requests and handle a large amount of access traffic.

2. The architecture of a food website

1. Module division

When creating a food website, we can split it into multiple modules, respectively Is:

• Front page: Displays the latest and hottest food information.
• Food details: Display detailed information, pictures and reviews of each food.
• Search: Provides the function of searching by food name, keywords, and geographical location.
• User Center: Provides user login, registration, personal information management, recipe uploading and other functions.
• Management background: Provides administrator login, food management, review, deletion, modification and other functions.

2. Database design

When designing the database, the data table of the food website can be divided into three parts:

• user table: stores the user’s basic information, such as user name, password, email, mobile phone number, etc.;
• recipe table: stores detailed information of the food, such as name, required materials, production process, pictures, reviews, etc. ;
• comment table: stores user evaluation and comment information.

3. Yii framework construction

1. Installing Yii framework

First you need to install Yii framework. You can install it through Composer:

composer create-project --prefer-dist yiisoft/yii2-app-basic your_project_name

2. Create database

Use MySQL database and create three tables: user, recipe, and comment.

3. Configure database connection

In the config/web.php file, perform the following configuration:

'components' => [
    'db' => [
        'class' => 'yiidbConnection',
        'dsn' => 'mysql:host=localhost;dbname=dbname',
        'username' => 'username',
        'password' => 'password',
        'charset' => 'utf8',
    ],
],

Need to modify the dbname, username, and password to Your own database parameters.

4. Create module

In the Yii framework, you can create modules through the Gii tool. First you need to enable Gii, which can be configured as follows in the config/web.php file:

$config = [
    'bootstrap' => ['gii'],
    'modules' => [
        'gii' => [
            'class' => 'yiigiiModule',
        ],
    ],
];

and configured in config/main-local.php:

$config['modules']['gii'] = [
    'class' => 'yiigiiModule',
    'allowedIPs' => ['127.0.0.1', '::1'],
];

and then enter http in the browser ://localhost/gii/ You can enter the Gii page and create the module.

5. Create models and controllers

After the module is created, you can create models and controllers and write code. For example, under the recipe module, create a Recipe controller and a Recipe model. And write the following code in the Recipe controller:

public function actionIndex()
{
    $recipes = Recipe::find()->all();
        
    return $this->render('index', [
        'recipes' => $recipes,
    ]);
}

Query the recipe data table through the Recipe::find()->all() method, and pass the results in the form of the $recipes variable .

Create a view file to display data. For example, in recipe/views/recipe/index.php, write the following code:

<?php foreach ($recipes as $recipe): ?>
<div class="recipe-item">
    <h2><?= Html::a(Html::encode($recipe->name), ['view', 'id' => $recipe->id]) ?></h2>
    <p><?= Html::encode($recipe->description) ?></p>
    <p><?= Html::a('查看详情', ['view', 'id' => $recipe->id]) ?></p>
</div>
<?php endforeach; ?>

Use the Html::a method to generate the link and pass the $recipe->id parameter.

6. Implementation of other functions

In addition to modules, controllers, and models, it is also necessary to implement functions such as search, user center, and administrator backend. I won’t list them all here, but simply introduce them as follows:

• Search: Use the ActiveRecord method provided by the Yii framework to query;
• User Center: Provide user authentication, information editing, and collection , upload and other functions;
• Administrator backend: Provides administrator login, review, add, delete, display and other functions.

4. Summary

This article introduces how to use the Yii framework to create a food website. Through a brief introduction to the Yii framework and the architecture of a food website, as well as sample code writing for the Yii framework, readers can have a preliminary understanding of how to use the Yii framework for web application development. Of course, developing a real food website requires more functions and details to implement, but through the information and reference provided in this article, I believe readers can already master the basic methods of how to use the Yii framework to build a simple food website.
