How to implement the classification and labeling functions of the accounting system - using PHP to develop classification and labeling functions requires specific code examples

With the popularity of the Internet and electronic With the rapid development of business, more and more users are beginning to use accounting systems to manage personal finances. A well-functioning and easy-to-use accounting system is inseparable from the support of classification and labeling functions. Classification and labeling functions can help users better organize and classify accounts, and facilitate users to count and query specific types of financial data. This article will introduce how to use PHP to develop the classification and labeling functions of the accounting system, and provide specific code examples.

1. Database design

First of all, we need to design a database to store the data of the accounting system. The accounting system mainly contains three tables: user table, account table and classification label table.

1. User table (user): used to store user information of the system, including fields such as user ID (uid), username (username) and password (password).

CREATE TABLE user (
uid INT(11) NOT NULL AUTO_INCREMENT,
username VARCHAR(50 ) NOT NULL,
password VARCHAR(50) NOT NULL,
PRIMARY KEY (uid)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Account table (account): used to store user account information, including account ID (aid), user ID (uid), account name (name), account type (type) and account amount (amount) fields.

CREATE TABLE account (
aid INT(11) NOT NULL AUTO_INCREMENT,
uid INT(11 ) NOT NULL,
name VARCHAR(50) NOT NULL,
type VARCHAR(50) NOT NULL,
amount DECIMAL( 10, 2) NOT NULL,
PRIMARY KEY (aid),
CONSTRAINT fk_user FOREIGN KEY (uid) REFERENCES user (uid) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3. Category label table (category): used to store accounts Category and tag information, including fields such as category ID (cid), category name (category_name), and tag name (tag_name).

CREATE TABLE category (
cid INT(11) NOT NULL AUTO_INCREMENT,
category_name VARCHAR(50 ) NOT NULL,
tag_name VARCHAR(50) NOT NULL,
PRIMARY KEY (cid)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. PHP development

1. Add classification and labeling functions

First, add a form on the front-end page for users to enter account information. At the same time, add a drop-down menu and multi-select box for users to select the classification and label of the account.

<?php
$categories = get_categories();  // 获取分类列表
foreach ($categories as $category) {
  echo "<option value="" . $category['cid'] . "">" . $category['category_name'] . "</option>";
}
?>

In the above code, the get_categories() function is called to obtain the category list stored in the database and display it to the user in the form of a drop-down menu. At the same time, a list of tags is displayed in the form of a multi-select box for users to select.

2. Save account information

When the user clicks the save button, the account information entered by the user and the selected classification and label information are saved to the database.

In the above code, the account information entered by the user is first obtained from the form and inserted into the account table. Then, associate the category ID and account ID and insert them into the category_account table. Finally, iterate through the tags selected by the user and insert the tag ID and account ID into the tag_account table.

3. Summary

Through the above steps, we have realized the classification and labeling functions of the accounting system. Users can organize and classify accounts by selecting categories and labels to facilitate query and statistics of specific types of financial data. During the development process, we used PHP to handle form data and database operations, and provided corresponding code examples. I hope this article will be helpful to developers who are developing accounting systems.
