How to use PHP to write the inventory counting plan management function code in the inventory management system

Inventory counting is one of the very important links in the inventory management system. It helps companies accurately understand the inventory situation and avoid excessive occurrences. or insufficient inventory. In a complete inventory management system, the inventory count plan management function is essential. This article will introduce how to use PHP to write code for inventory counting plan management functions.

First, we need to create a database to store information related to the inventory count plan. Assume that we have created a database named inventory, in which there is a table named inventory_check to store information about the inventory count plan. The structure of the inventory_check table is as follows:

CREATE TABLE `inventory_check` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `date` date NOT NULL,
  `status` enum('draft', 'in_progress', 'completed') NOT NULL,
  PRIMARY KEY (`id`)
);

Next, we need to write PHP code to implement the inventory count plan management function. First, we need to connect to the MySQL database. Assume that we already have a connection object named $connection, which can be connected through the following code:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "inventory";

$connection = new mysqli($servername, $username, $password, $dbname);

if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}
?>

After connecting to the database, we can start writing the code for the inventory count plan management function. First, we need to write a function to create the inventory count plan. The code example is as follows:

<?php
function createInventoryCheck($name, $date) {
    global $connection;

    $sql = "INSERT INTO inventory_check (name, date, status) VALUES ('$name', '$date', 'draft')";

    if ($connection->query($sql) === TRUE) {
        echo "Inventory check created successfully";
    } else {
        echo "Error creating inventory check: " . $connection->error;
    }
}
?>

In the above code, we use the INSERT INTO statement to insert the name, date and status (initially draft) of the inventory count plan into the inventory_check table.

Next, we can write a function to obtain information about the inventory count plan. The code example is as follows:

<?php
function getInventoryChecks() {
    global $connection;

    $sql = "SELECT * FROM inventory_check";
    $result = $connection->query($sql);

    if ($result->num_rows > 0) {
        while($row = $result->fetch_assoc()) {
            echo "ID: " . $row["id"]. " - Name: " . $row["name"]. " - Date: " . $row["date"]. " - Status: " . $row["status"]. "<br>";
        }
    } else {
        echo "No inventory checks found";
    }
}
?>

In the above code, we use the SELECT statement to obtain all inventory count plan information from the inventory_check table and print it out line by line.

In addition to creating and obtaining information about the inventory count plan, we can also write functions to update the status of the inventory count plan. The code example is as follows:

<?php
function updateInventoryCheckStatus($id, $status) {
    global $connection;

    $sql = "UPDATE inventory_check SET status='$status' WHERE id=$id";

    if ($connection->query($sql) === TRUE) {
        echo "Inventory check status updated successfully";
    } else {
        echo "Error updating inventory check status: " . $connection->error;
    }
}
?>

In the above code, we use the UPDATE statement to update the status of the inventory count plan with the specified ID to the specified status.

Finally, after use, we need to close the connection to the database. The code example is as follows:

<?php
$connection->close();
?>

Through the above code example, we can implement the basic functions of the inventory count plan management function, including creating the inventory count plan, obtaining the information of the inventory count plan, and updating the status of the inventory count plan. Of course, based on actual needs, we can add more functions to improve the inventory count plan management function.

To sum up, by writing the inventory count plan management function code in the inventory management system in PHP, we can manage and control the inventory count plan more conveniently, thus improving the efficiency and accuracy of inventory management.
