How to add a custom template function to the accounting system - How to use PHP to develop custom templates requires specific code examples

1. Introduction:
Note An accounting system is an application used to record financial information such as personal or business income, expenses, assets, and liabilities. In actual use, different users or enterprises may require different ways of displaying accounts, so adding custom template functions can improve the flexibility and user experience of the system. This article will introduce how to use PHP to develop custom template functions and provide specific code examples.

2. Implementation steps:

1. Create database table:
   First, you need to create a table in the database to store custom template information. You can create a table named "templates", containing the following fields:
2. id: Template ID, as a unique identifier
3. name: Template name, used to display in the system
4. code: Template code, template code written using HTML and CSS
5. Create a template management page:
   Use PHP language to create a template management page to display the existing template list and provide the ability to add , update and delete template functions.
6. Add template function:
   In the template management page, add a form for adding new templates. The form contains two input boxes for template name and template code, as well as a submit button. When the user completes filling out the form, click the submit button to submit the form data to the server-side PHP script.
7. Database insertion operation:
   In the server-side PHP script, after receiving the data submitted by the form, insert the data into the "templates" table of the database. You can use MySQL's INSERT statement to implement data insertion operations.
8. Update template function:
   In the template management page, add an update button for each template. When the user clicks the update button, it jumps to a new page, displays the name and code of the current template, and provides a modification save button. Users can modify the name and code of the template in the new page, and click the save button to submit the modified data to the server-side PHP script.
9. Database update operation:
   In the server-side PHP script, after receiving the modified data, use the corresponding UPDATE statement to update the data to the "templates" table of the database.
10. Delete template function:
    In the template management page, add a delete button for each template. When the user clicks the delete button, a confirmation dialog box pops up asking the user to confirm the deletion. If the user confirms the deletion, the ID of the template is submitted to the server-side PHP script for deletion.
11. Database deletion operation:
    In the server-side PHP script, after receiving the template ID to be deleted, use the DELETE statement to delete the template from the "templates" table of the database.
12. Use custom templates:
    In the code of the accounting system, add a template selection function to allow users to choose to use a custom template when creating new accounts. When the user chooses to use a custom template, the selected template ID is stored in the database for subsequent use when displaying accounts.

3. Specific code examples:

1. Create database table:

CREATE TABLE templates (
   id INT PRIMARY KEY AUTO_INCREMENT,
   name VARCHAR(255),
   code TEXT
);

2. Template management page:

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

// 查询所有模板
$result = mysqli_query($conn, "SELECT * FROM templates");

// 显示模板列表
while ($row = mysqli_fetch_assoc($result)) {
   echo "<p>{$row['name']} <a href='edit_template.php?id={$row['id']}'>编辑</a> <a href='delete_template.php?id={$row['id']}'>删除</a></p>";
}
?>

3. Add Template function:

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

// 插入新模板
$name = $_POST['name'];
$code = $_POST['code'];
mysqli_query($conn, "INSERT INTO templates (name, code) VALUES ('$name', '$code')");

// 返回模板管理页面
header("Location: template.php");
exit;
?>

4. Update template function:
Edit template page (edit_template.php)

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

// 获取要编辑的模板ID
$id = $_GET['id'];

// 查询要编辑的模板信息
$result = mysqli_query($conn, "SELECT * FROM templates WHERE id=$id");
$row = mysqli_fetch_assoc($result);

// 显示当前模板信息和编辑表单
echo "<p>当前模板名称：{$row['name']}</p>";
echo "<textarea name='code'>{$row['code']}</textarea>";
echo "<button onclick='saveTemplate($id)'>保存</button>";
?>
<script>
function saveTemplate(id) {
   var code = document.querySelector("textarea[name='code']").value;
   // 跳转到保存模板的PHP脚本，并将修改后的数据提交
   window.location.href = "save_template.php?id=" + id + "&code=" + encodeURIComponent(code);
}
</script>

Save template function (save_template.php)

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

// 更新模板代码
$id = $_GET['id'];
$code = $_GET['code'];
mysqli_query($conn, "UPDATE templates SET code='$code' WHERE id=$id");

// 返回模板管理页面
header("Location: template.php");
exit;
?>

5 .Delete the template function:

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

// 获取要删除的模板ID
$id = $_GET['id'];

// 删除模板
mysqli_query($conn, "DELETE FROM templates WHERE id=$id");

// 返回模板管理页面
header("Location: template.php");
exit;
?>

The above are the steps and corresponding code examples for using PHP to develop the custom template function of the accounting system. By adding the custom template function, users can flexibly customize the account display method of the accounting system according to their own needs, improving the system's flexibility and user experience.
