Create a recruitment information website using Yii framework

With the continuous advancement of the Internet, finding a job no longer requires going through newspapers or recruitment agencies as before, but through various recruitment websites. The biggest advantages of these recruitment websites are their convenience and rich information, so both job seekers and employers can easily find the information they want on them. If you also want to create a similar recruitment information website, then you can consider using the Yii framework to achieve it.

Yii framework is an efficient, safe and stable PHP framework. It is built in MVC mode and has excellent performance and security. The Yii framework provides a large number of tools and components, including caching, security authentication, web services, etc., to make program development more convenient and efficient.

First, you need to install the Yii framework. The Yii framework can be installed through the Composer package manager, which allows you to easily develop and maintain applications. Note that you need to make sure your server has PHP 5.6 or higher installed.

After the installation is complete, you need to create a new Yii application, which can be created using the command yicreateapp provided by the Yii framework, which will automatically create a base application for you.

Next, you need to design the database structure. In this example, we will use a MySQL database and create a database named "jobs". Create two data tables in this database:

1. User table (user) - contains the user's user name, password and other information.

2. Job list (job) - contains the title, description, work location and other information of the recruitment information.

After launching your Yii application, you need to set up the basic configuration of the application, which usually includes the database connection and components such as the application's controllers, models, and views. In a Yii application, use the main.php file in the config folder to make these settings.

In this website, users should be able to register a new account or log in using an existing account. For employers, opening their job postings page and posting new job vacancies is a must, while job seekers need to browse job postings and apply. Therefore, we need to create different types of user roles and assign corresponding permissions to each.

In Yii applications, you can define permissions by using access control filters, which allows you to limit the operations of logged-in users in the application for different roles. Add the following code to the main.php file in the config folder:

'components'=>
'user'=>array(

       'class'=>'WebUser',
       'allowAutoLogin'=>true,
       'loginUrl'=>array('/login'),

),
'authManager'=>array(

    'class'=>'CDbAuthManager',
    'connectionID'=>'db',
    'itemTable'=>'auth_item',
    'itemChildTable'=>'auth_item_child',
    'assignmentTable'=>'auth_assignment',
),

'urlManager'=>array(

    'urlFormat'=>'path',
    'rules'=>array(
          '<id:d+>/<title:.*?>'=>'job/view',
          'jobs/<tags:.*?>'=>'job/index',
          '<controller:w+>/<action:w+>'=>'<controller>/<action>',
    ),

)

In this code, we define a "user" Component, which allows users to automatically log in and define login pages. It also defines a database-based permission management system through the "authManager" component. Finally, the rules for URL routing are configured.

A simple recruitment information website The application is complete. Now you can open the application and test it. This will demonstrate some basic functions you have created in the Yii framework. Of course, this website can be further optimized and add more functions, such as email Notifications and SEO, etc.

In conclusion, building a job posting website by using the Yii framework is not complicated, but it requires time and effort. Using the Yii framework, you can accomplish this task cost-effectively, At the same time, it improves the maintainability and security of the website.
