The production planning module function developed by PHP to build an enterprise resource planning (ERP) system

The enterprise resource planning (ERP) system is a management software that integrates various departments and processes, which can help enterprises achieve high efficiency resource management and business process optimization. Among them, the production planning module is an important part of the ERP system. It can help enterprises formulate and implement efficient production plans and improve production efficiency and responsiveness. This article will introduce how to use PHP to develop a simple production planning module function.

First, we need to create a table in the database of the ERP system to store production plan information. The following is a simple sample code:

CREATE TABLE production_plan (
  id INT PRIMARY KEY AUTO_INCREMENT,
  product_name VARCHAR(50) NOT NULL,
  quantity INT NOT NULL,
  start_date DATE NOT NULL,
  end_date DATE NOT NULL,
  status VARCHAR(20) NOT NULL
);

In the above code, we created a table named production_plan to store information related to the production plan, including the plan’s unique identification id, product name, plan Fields such as quantity, start date, end date, and status.

Next, we can use PHP to develop a simple production plan management class to implement the functions of adding, editing, deleting and querying plans. The following is a sample code:

class ProductionPlanManager {
  private $conn;

  public function __construct($db) {
    $this->conn = $db;
  }

  public function addPlan($product_name, $quantity, $start_date, $end_date) {
    $status = '待执行'; // 默认状态为待执行
    $sql = "INSERT INTO production_plan (product_name, quantity, start_date, end_date, status) VALUES (:product_name, :quantity, :start_date, :end_date, :status)";
    $stmt = $this->conn->prepare($sql);
    $stmt->bindParam(':product_name', $product_name);
    $stmt->bindParam(':quantity', $quantity);
    $stmt->bindParam(':start_date', $start_date);
    $stmt->bindParam(':end_date', $end_date);
    $stmt->bindParam(':status', $status);
    if ($stmt->execute()) {
      return true;
    } else {
      return false;
    }
  }

  public function editPlan($id, $product_name, $quantity, $start_date, $end_date) {
    $sql = "UPDATE production_plan SET product_name = :product_name, quantity = :quantity, start_date = :start_date, end_date = :end_date WHERE id = :id";
    $stmt = $this->conn->prepare($sql);
    $stmt->bindParam(':id', $id);
    $stmt->bindParam(':product_name', $product_name);
    $stmt->bindParam(':quantity', $quantity);
    $stmt->bindParam(':start_date', $start_date);
    $stmt->bindParam(':end_date', $end_date);
    if ($stmt->execute()) {
      return true;
    } else {
      return false;
    }
  }

  public function deletePlan($id) {
    $sql = "DELETE FROM production_plan WHERE id = :id";
    $stmt = $this->conn->prepare($sql);
    $stmt->bindParam(':id', $id);
    if ($stmt->execute()) {
      return true;
    } else {
      return false;
    }
  }

  public function getPlan($id) {
    $sql = "SELECT * FROM production_plan WHERE id = :id";
    $stmt = $this->conn->prepare($sql);
    $stmt->bindParam(':id', $id);
    $stmt->execute();
    return $stmt->fetch(PDO::FETCH_ASSOC);
  }

  public function getAllPlans() {
    $sql = "SELECT * FROM production_plan";
    $stmt = $this->conn->prepare($sql);
    $stmt->execute();
    return $stmt->fetchAll(PDO::FETCH_ASSOC);
  }
}

// 使用示例：
$pdo = new PDO('mysql:host=localhost;dbname=erp', 'username', 'password');
$planManager = new ProductionPlanManager($pdo);
$planManager->addPlan('产品A', 100, '2022-01-01', '2022-02-01');
$planManager->editPlan(1, '产品B', 200, '2022-01-01', '2022-03-01');
$planManager->deletePlan(2);
$plan = $planManager->getPlan(1);
$plans = $planManager->getAllPlans();

In the above sample code, we created a class named ProductionPlanManager, which contains methods for adding, editing, deleting and querying production plans. Using the database connection and code that instantiates the ProductionPlanManager class in the sample code, we can easily manage and operate the production plan.

Through the above simple example, we can see how to use PHP to develop a basic production planning module function. Of course, more functions and details need to be considered in actual development, such as permission control, data verification, error handling, etc. At the same time, the code can also be expanded and optimized according to specific needs to achieve more efficient and easy-to-use production plan management functions.

In short, using PHP to develop the production planning module function of the enterprise resource planning (ERP) system has great flexibility and scalability, and can be customized and optimized according to specific needs to help enterprises achieve efficient production planning. Management and business process optimization.
