How to add batch operation function to the accounting system - using PHP to develop batch operation methods requires specific code examples

With the development of the Internet, the accounting system is in plays an important role in our daily lives. However, as time passes and the amount of data increases, manual operations become less efficient. In order to improve users' work efficiency, we can add batch operation functions to the accounting system. This article will introduce how to use PHP to develop batch operations and provide specific code examples.

1. Requirements Analysis
Before adding the batch operation function, we first need to clarify the user's needs. In accounting systems, common batch operation functions include batch deletion, batch editing, batch import, and batch export.

2. PHP development batch operation method

Batch deletion
Batch deletion is one of the most common batch operations in the accounting system. We can implement the batch deletion function through the following steps:

(1) Display the list of data to be deleted on the front-end page, and provide check boxes for users to select the data that needs to be deleted.
(2) After the user selects the data to be deleted, click the delete button.
(3) The front end sends the selected data ID to the background PHP file for processing through AJAX.
(4) After the background PHP file receives the data ID, it deletes the selected data from the database through SQL statements.

The specific code examples are as follows:

Front-end page (HTML):

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>批量删除</title>
</head>
<body>
    <form id="deleteForm" method="POST">
        <table>
            <tr>
                <th>选择</th>
                <th>数据</th>
            </tr>
            <tr>
                <td><input type="checkbox" name="data[]" value="1"></td>
                <td>数据1</td>
            </tr>
            <tr>
                <td><input type="checkbox" name="data[]" value="2"></td>
                <td>数据2</td>
            </tr>
            <tr>
                <td><input type="checkbox" name="data[]" value="3"></td>
                <td>数据3</td>
            </tr>
        </table>
        <input type="submit" value="删除">
    </form>
</body>
</html>

Backend PHP file:

<?php
    // 连接数据库
    $conn = mysqli_connect("localhost", "root", "password", "database");

    // 检查是否连接成功
    if (mysqli_connect_errno()) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        // 获取选中的数据ID
        $dataIds = $_POST["data"];

        // 删除数据
        foreach ($dataIds as $dataId) {
            $sql = "DELETE FROM table_name WHERE id = " . $dataId;
            mysqli_query($conn, $sql);
        }
    }

    // 关闭数据库连接
    mysqli_close($conn);
?>

Batch editing
The batch editing function allows users to modify the properties of multiple pieces of data at the same time. The method of implementing batch editing is similar to batch deletion. You only need to change the deletion operation to an update operation. The specific code example is similar to batch deletion and will not be repeated here.
Batch import
Batch import is a very practical function, which can import the user's existing data into the accounting system in batches. We can implement the batch import function through the following steps:

(1) The front-end page provides a file upload form to allow users to select the files that need to be imported.
(2) The front end sends the file to the background PHP file for processing through AJAX.
(3) After receiving the file, the background PHP file parses the file data and stores the parsed data in the database.

The specific code examples are as follows:

Front-end page (HTML):

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>批量导入</title>
</head>
<body>
    <form id="importForm" method="POST" enctype="multipart/form-data">
        <input type="file" name="file" accept=".csv">
        <input type="submit" value="导入">
    </form>
</body>
</html>

Backend PHP file:

<?php
    // 连接数据库
    $conn = mysqli_connect("localhost", "root", "password", "database");

    // 检查是否连接成功
    if (mysqli_connect_errno()) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        // 获取上传的文件名和临时文件路径
        $fileName = $_FILES["file"]["name"];
        $tempName = $_FILES["file"]["tmp_name"];

        // 读取文件数据
        $file = fopen($tempName, "r");
        while (($data = fgetcsv($file, 1000, ",")) !== FALSE) {
            // 解析文件数据并插入数据库
            $sql = "INSERT INTO table_name (column1, column2, column3) VALUES ('" . $data[0] . "', '" . $data[1] . "', '" . $data[2] . "')";
            mysqli_query($conn, $sql);
        }
        fclose($file);
    }

    // 关闭数据库连接
    mysqli_close($conn);
?>

Batch export
The batch export function can export data in the database to files in specified formats, such as CSV files or Excel files. The method of implementing batch export is similar to batch import. You only need to save the data in the file and read the data from the file. The specific code example is similar to batch import and will not be described again here.

Through the above code examples, we can add batch operation functions to the accounting system to improve user work efficiency. Of course, the code implementation may be different depending on specific project needs, and needs to be adapted and adjusted according to the actual situation. Hope this article is helpful to you.
