PHP development of enterprise resource planning (ERP) system to build quality inspection function

PHP development of enterprise resource planning (ERP) system to build quality inspection function

Introduction:
With the development of enterprise business and the intensification of competition, quality control and quality management are becoming more and more important. important. In order to ensure the quality of products and services, companies need to establish a complete quality inspection system. In the enterprise resource planning (ERP) system, the development and implementation of quality inspection functions are crucial to the operation and management of the enterprise. This article will introduce how to use PHP to develop and build an ERP system with quality inspection functions, and give corresponding code examples.

1. Requirements Analysis
In actual development, we need to conduct needs analysis first to clarify the function and performance requirements of the system. In the ERP system that builds the quality inspection function, the following functions mainly need to be implemented:

1. Create a new quality inspection task: Create a new quality inspection task based on the order or purchase order information, and record the corresponding products and inspection parameters .

Sample code:

function createInspectionTask($order_id, $product_id, $params) {
   // 新建质检任务并插入数据库
   // ...
   return $task_id;
}

2. Assign quality inspection tasks: Assign quality inspection tasks to appropriate quality inspectors based on their workload and abilities.

Sample code:

function assignInspectionTask($task_id, $inspector_id) {
   // 将质检任务分配给质检员，并更新数据库中的相关字段
   // ...
}

3. Quality inspection result entry: The quality inspector fills in the quality inspection results according to the product inspection standards and enters the results into the system.

Sample code:

function enterInspectionResult($task_id, $result) {
   // 将质检结果录入数据库，并更新相应字段
   // ...
}

4. Quality inspection result query: Production supervisors and quality management personnel can query the quality inspection results through the system and make corresponding decisions based on the results.

Sample code:

function getInspectionResult($task_id) {
   // 从数据库中查询质检结果，并返回结果
   // ...
   return $result;
}

2. Detailed design
After clarifying the function and performance requirements of the system during the requirements analysis stage, we need to carry out detailed design, including database design, System architecture design and interface design, etc.

1. Database design
   Quality inspection task table (inspection_task): includes fields such as task ID, order number, product ID, etc. Used to record basic information of quality inspection tasks.

Sample code:

CREATE TABLE inspection_task (
   task_id INT PRIMARY KEY AUTO_INCREMENT,
   order_id INT,
   product_id INT,
   ... -- 其他字段
);

Quality inspection results table (inspection_result): includes fields such as task ID, inspection results, etc. Used to record inspection results of quality inspection tasks.

Sample code:

CREATE TABLE inspection_result (
   task_id INT PRIMARY KEY,
   result VARCHAR(255),
   ... -- 其他字段
);

2. System architecture design
   When developing the quality inspection function of the ERP system, we can use the MVC (Model-View-Controller) architecture to integrate the system It is divided into model layer, view layer and controller layer.

Model layer (Model): Responsible for interacting with the database and performing data query and update.

Sample code:

class InspectionTaskModel {
   public function createTask($order_id, $product_id, $params) {
      // 新建质检任务并插入数据库
      // ...
      return $task_id;
   }
 
   public function assignTask($task_id, $inspector_id) {
      // 将质检任务分配给质检员，并更新数据库中的相关字段
      // ...
   }
 
   public function enterResult($task_id, $result) {
      // 将质检结果录入数据库，并更新相应字段
      // ...
   }
 
   public function getResult($task_id) {
      // 从数据库中查询质检结果，并返回结果
      // ...
      return $result;
   }
}

View layer (View): Responsible for displaying data and receiving user input.

Sample code:

class InspectionTaskView {
   // 显示新建质检任务的表单
   public function showCreateTaskForm() {
      // ...
   }
 
   // 显示质检结果录入的表单
   public function showEnterResultForm() {
      // ...
   }
 
   // 显示质检结果查询的界面
   public function showCheckResultPage() {
      // ...
   }
   // ...
}

Controller layer (Controller): Responsible for processing user requests and calling methods of the model layer and view layer.

Sample code:

class InspectionTaskController {
   private $model;
   private $view;
 
   public function __construct() {
      $this->model = new InspectionTaskModel();
      $this->view = new InspectionTaskView();
   }
 
   public function createTask() {
      // 处理新建质检任务的请求
      $order_id = $_POST['order_id'];
      $product_id = $_POST['product_id'];
      $params = $_POST['params'];
      $task_id = $this->model->createTask($order_id, $product_id, $params);
      $this->view->showEnterResultForm($task_id);
   }
 
   public function assignTask() {
      // 处理质检任务分配的请求
      $task_id = $_POST['task_id'];
      $inspector_id = $_POST['inspector_id'];
      $this->model->assignTask($task_id, $inspector_id);
      $this->view->showCheckResultPage();
   }
 
   public function enterResult() {
      // 处理质检结果录入的请求
      $task_id = $_POST['task_id'];
      $result = $_POST['result'];
      $this->model->enterResult($task_id, $result);
      $this->view->showCheckResultPage();
   }
 
   public function checkResult() {
     // 处理质检结果查询的请求
     $task_id = $_GET['task_id'];
     $result = $this->model->getResult($task_id);
     $this->view->showResult($result);
   }
   // ...
}

3. System implementation
After completing the detailed design, we can start to implement each module of the system.

1. New quality inspection task module implementation

$controller = new InspectionTaskController();
$controller->createTask();

2. Quality inspection task allocation module implementation

$controller = new InspectionTaskController();
$controller->assignTask();

3. Quality inspection results Input module implementation

$controller = new InspectionTaskController();
$controller->enterResult();

4. Quality inspection result query module implementation

$controller = new InspectionTaskController();
$controller->checkResult();

Summary:
This article introduces how to use PHP to develop and build enterprises with quality inspection functions Resource planning (ERP) system. Through requirements analysis, detailed design and system implementation, we obtained an ERP system with the functions of quality inspection task management, quality inspection result entry and quality inspection result query. Through the hierarchical design of the model layer, view layer and controller layer, the system architecture is made clearer and the maintainability and scalability of the system are improved. Through code examples, readers can better understand the design and implementation process of the system. I hope this article will be helpful to the development of ERP systems with PHP quality inspection functions.
