PHP development of an enterprise resource planning (ERP) system that builds procurement qualification rate management functions

PHP development of enterprise resource planning (ERP) system to build procurement qualification rate management function

Introduction:
In modern enterprise management, procurement qualification rate is a very important indicator, which reflects Whether the materials purchased by an enterprise meet quality standards is directly related to the quality and competitiveness of the enterprise's products. Therefore, it is crucial to build an enterprise resource planning (ERP) system that can monitor and manage procurement qualification rates in real time. This article will introduce the design and implementation of the procurement qualification rate management function module developed based on PHP, and attach relevant code examples.

1. Functional requirements analysis:

1. Real-time monitoring: can obtain the quality information of purchased materials in real time and conduct real-time monitoring;
2. Data entry: can Enter the quality information of purchased materials, including material code, purchase date, quality standards, etc.;
3. Data retrieval: data retrieval can be performed based on material code, purchase date and other conditions;
4. Data statistics: can conduct statistics on the qualification rate of purchased materials, and conduct statistics according to material code, purchase date, supplier and other dimensions;
5. Data report: can generate a data report of the procurement qualification rate, displaying the results of each dimension Qualification rate information;
6. Reminder function: When the qualification rate of purchased materials is lower than the set warning line, a warning message can be issued.

2. System design and implementation:

1. Database design:
   Create a database named purchase_quality, containing the following two tables: materials and quality_info.

   materials table structure:

   CREATE TABLE materials (
      id INT PRIMARY KEY AUTO_INCREMENT,
      code VARCHAR(20) NOT NULL,
      name VARCHAR(50) NOT NULL,
      supplier VARCHAR(50) NOT NULL
   );

   quality_info table structure:

   CREATE TABLE quality_info (
      id INT PRIMARY KEY AUTO_INCREMENT,
      material_id INT NOT NULL,
      purchase_date DATE NOT NULL,
      standard VARCHAR(50) NOT NULL,
      qualified INT(1) NOT NULL,
      FOREIGN KEY(material_id) REFERENCES materials(id)
   );

2. System development:
   Develop a PHP project named purchase_quality, including The following files:

   • index.php: The main page of the system, showing the data report of the procurement qualification rate;
   • add.php: Entering the quality information of the purchased materials;
   • search.php: Data retrieval based on conditions;
   • statistics.php: Statistics on the pass rate of purchased materials;
   • reminder.php: Implementation of the reminder function.

   Code example:

   // index.php
   <?php
   // 查询数据库，获取采购合格率数据信息
   $sql = "SELECT m.name, m.supplier, COUNT(q.qualified) AS total, SUM(q.qualified) AS qualified
           FROM materials m
           INNER JOIN quality_info q ON m.id = q.material_id
           GROUP BY m.name, m.supplier";
   // 执行SQL查询语句...
   
   // 输出数据报表
   while ($row = mysqli_fetch_assoc($result)) {
      $name = $row['name'];
      $supplier = $row['supplier'];
      $total = $row['total'];
      $qualified = $row['qualified'];
      $rate = $qualified / $total * 100;
      echo "物料名称：$name，供应商：$supplier，合格率：$rate%<br>";
   }
   ?>
   
   // add.php
   <?php
   // 处理表单提交的数据，插入到数据库中
   $code = $_POST['code'];
   $purchaseDate = $_POST['purchase_date'];
   $standard = $_POST['standard'];
   $qualified = $_POST['qualified'];
   
   $sql = "INSERT INTO quality_info (material_id, purchase_date, standard, qualified)
           VALUES ('$materialId', '$purchaseDate', '$standard', '$qualified')";
   // 执行SQL插入语句...
   ?>
   
   // search.php
   <?php
   // 处理表单提交的条件，查询数据库并输出结果
   $code = $_POST['code'];
   $purchaseDate = $_POST['purchase_date'];
   
   $sql = "SELECT m.name, q.purchase_date, q.standard, q.qualified
           FROM materials m
           INNER JOIN quality_info q ON m.id = q.material_id
           WHERE m.code = '$code' AND q.purchase_date = '$purchaseDate'";
   // 执行SQL查询语句...
   ?>
   
   // statistics.php
   <?php
   // 查询数据库，统计采购物料的合格率
   $sql = "SELECT m.name, COUNT(q.qualified) AS total, SUM(q.qualified) AS qualified
           FROM materials m
           INNER JOIN quality_info q ON m.id = q.material_id
           GROUP BY m.name";
   // 执行SQL查询语句...
   
   // 输出统计结果
   while ($row = mysqli_fetch_assoc($result)) {
      $name = $row['name'];
      $total = $row['total'];
      $qualified = $row['qualified'];
      $rate = $qualified / $total * 100;
      echo "物料名称：$name，合格率：$rate%<br>";
   }
   ?>
   
   // reminder.php
   <?php
   // 查询数据库，获取采购物料的合格率信息，并进行判断
   $sql = "SELECT m.name, m.supplier, COUNT(q.qualified) AS total, SUM(q.qualified) AS qualified
           FROM materials m
           INNER JOIN quality_info q ON m.id = q.material_id
           GROUP BY m.name, m.supplier";
   // 执行SQL查询语句...
   
   // 判断是否低于警戒线，并发送提醒信息
   while ($row = mysqli_fetch_assoc($result)) {
      $name = $row['name'];
      $supplier = $row['supplier'];
      $total = $row['total'];
      $qualified = $row['qualified'];
      $rate = $qualified / $total * 100;
   
      if ($rate < 90) {
         echo "物料名称：$name，供应商：$supplier，合格率：$rate%，低于警戒线，请及时采取措施！<br>";
         // 发送提醒信息...
      }
   }
   ?>

3. Summary:
This article demonstrates an enterprise that builds procurement qualification rate management functions through examples developed using PHP. Resource planning (ERP) system implementation process.
