How to use PHP and UniApp to realize the user's personal setting function

With the development of the mobile Internet, the user's personal setting function has received more and more attention. Through the personal settings function, users can customize the appearance, functions and personal information of the application to improve user experience and personalization. This article will introduce how to use PHP and UniApp to implement user personal setting functions, and attach specific code examples.

1. Project preparation
First, you need to configure the development environment, including installing PHP and UniApp development environment. Make sure the PHP environment is running normally and has permission to connect to the database.

2. Create database and table structure
Create a database named "users" in MySQL, and create a table named "settings" in the database to save the user's personal information set up. The table structure is as follows:

CREATE TABLE IF NOT EXISTS settings (
id int(11) NOT NULL AUTO_INCREMENT,
user_id int(11) NOT NULL,
name varchar(255) NOT NULL,
value text NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

##3. Backend PHP code implementation

Create a file named "config.php", use To configure database connection information:

Create a file named "settings.php", Logic for processing user personal settings:

4. Front-end UniApp code implementation

Create a file named "settings.vue" in UniApp for displaying and editing user personal settings:

<view>
    <input v-model="name" placeholder="请输入设置名称" />
    <input v-model="value" placeholder="请输入设置值" />
    <button @click="saveSettings">保存设置</button>
</view>

export default {
    data() {
        return {
            name: '',
            value: ''
        }
    },
    methods: {
        saveSettings() {
            uni.request({
                url: 'http://localhost/settings.php',
                method: 'POST',
                data: {
                    user_id: '1',  // 当前用户ID
                    name: this.name,
                    value: this.value
                },
                success: (res) => {
                    console.log(res.data);
                    if (res.data.status === 'success') {
                        uni.showToast({
                            title: '保存成功',
                            icon: 'success'
                        });
                    } else {
                        uni.showToast({
                            title: '保存失败',
                            icon: 'none'
                        });
                    }
                },
                fail: () => {
                    uni.showToast({
                        title: '请求失败',
                        icon: 'none'
                    });
                }
            });
        }
    }
}

5. Summary

Through the combination of PHP and UniApp, we can easily realize user Personal settings function. By writing back-end PHP code to realize database connection and operation, and writing front-end UniApp code to realize user interface display and interaction, we can realize the storage and update functions of user's personal settings.
