How to use ThinkPHP6 to implement ORM to automatically verify database operations

thinkphp orm Automatic verification

As the functionality of web applications continues to increase, developers often need to spend a lot of time writing database validation rules. Using the ORM (Object Relational Mapping) framework, database validation rules and business logic can be separated, saving time and improving development efficiency. Among them, ThinkPHP6 provides an automatic verification function, which can help us quickly implement ORM automatic verification database operations. Next, we will introduce how to use ThinkPHP6 to implement ORM automatic verification database operations.

  1. Install ThinkPHP6

First, we need to install ThinkPHP6. You can use Composer to install ThinkPHP6 through the following command:

composer create-project topthink/think tp6 --prefer-dist

Of course, you can also go to the official website of ThinkPHP6 (https://www.thinkphp.cn) Download the latest framework source code.

  1. Configuring the database connection

Before implementing ORM automatic verification, we need to configure the database connection first. It can be configured in config/database.php in the project root directory, for example:

return [
    // 數(shù)據(jù)庫類型
    'type'            => 'mysql',
    // 數(shù)據(jù)庫連接DSN配置
    'dsn'             => '',
    // 服務(wù)器地址
    'hostname'        => '127.0.0.1',
    // 數(shù)據(jù)庫名
    'database'        => 'test',
    // 數(shù)據(jù)庫用戶名
    'username'        => 'root',
    // 數(shù)據(jù)庫密碼
    'password'        => 'password',
    // 數(shù)據(jù)庫連接端口
    'hostport'        => '3306',
    // 數(shù)據(jù)庫連接參數(shù)
    'params'          => [],
    // 數(shù)據(jù)庫編碼默認采用utf8
    'charset'         => 'utf8',
    // 數(shù)據(jù)庫表前綴
    'prefix'          => '',
    // 數(shù)據(jù)庫調(diào)試模式
    'debug'           => true,
    // 數(shù)據(jù)庫部署方式:0 集中式(單一服務(wù)器),1 分布式(主從服務(wù)器)
    'deploy'          => 0,
    // 數(shù)據(jù)庫讀寫是否分離 主從式有效
    'rw_separate'     => false,
    // 讀寫分離后 主服務(wù)器數(shù)量
    'master_num'      => 1,
    // 指定從服務(wù)器序號
    'slave_no'        => '',
    // 是否嚴格檢查字段是否存在
    'fields_strict'   => true,
    // 數(shù)據(jù)集返回類型
    'resultset_type'  => 'array',
    // 是否自動寫入時間戳字段
    'auto_timestamp'  => false,
    // 是否需要進行SQL性能分析
    'sql_explain'     => false,
    // 開啟斷線重連
    'break_reconnect' => true,
];
  1. Creating and using models

In ThinkPHP6 , use models to interact with the database. You can create a model through the following command:

php bin/think make:model Test

This command will be created in the app directory Test.php file, which contains an empty model class Test. We can specify database operation table names, primary key names, automatic timestamps and other definitions in this class. For example:

<?php
namespace appmodel;
use thinkModel;
class Test extends Model
{
    // 指定表名
    protected $table = 'test';
    // 指定主鍵名
    protected $pk = 'id';
    // 自動時間戳
    protected $autoWriteTimestamp = true;
}

In this model class, we can also define some data validation rules. For example:

<?php
namespace appmodel;
use thinkModel;
class Test extends Model
{
    // 指定表名
    protected $table = 'test';
    // 指定主鍵名
    protected $pk = 'id';
    // 自動時間戳
    protected $autoWriteTimestamp = true;

    // 定義驗證規(guī)則
    protected $validate=[
        'name'=>'require|max:10',
        'age'=>'require|integer|between:1,100',
        'email'=>'email',
    ];
}

In this example, we define three validation rules: nameRequired, the maximum length is 10; ageRequired, must be an integer, take The value is between 1 and 100; email must be in email format. These rules will be automatically verified when operating on model data.

  1. Use the automatic verification function

When using the model for database operations, we only need to call the corresponding method, for example:

// 添加數(shù)據(jù)
$data = [
    'name' => '張三',
    'age'  => '18',
    'email'=> 'zhangsan@test.com',
];
$model = new Test;
$result = $model->save($data);
if ($result) {
    echo '數(shù)據(jù)添加成功';
} else {
    echo '數(shù)據(jù)添加失敗';
}

// 更新數(shù)據(jù)
$data = [
    'id'   => 1,
    'name' => '李四',
    'age'  => '20',
    'email'=> 'lisi@test.com',
];
$model = new Test;
$result = $model->save($data, ['id' => 1]);
if ($result) {
    echo '數(shù)據(jù)更新成功';
} else {
    echo '數(shù)據(jù)更新失敗';
}

// 刪除數(shù)據(jù)
$model = new Test;
$result = $model->destroy(1);
if ($result) {
    echo '數(shù)據(jù)刪除成功';
} else {
    echo '數(shù)據(jù)刪除失敗';
}

// 查詢數(shù)據(jù)
$model = new Test;
$result = $model->where('id', 1)->find();
if ($result) {
    echo '數(shù)據(jù)查詢成功';
} else {
    echo '數(shù)據(jù)查詢失敗';
}

In When using these methods, ThinkPHP6 automatically validates based on the validation rules defined in the model. If validation fails, an exception is thrown and the reason for the failure is returned.

  1. Custom validation message

In automatic validation, we can define the validation message when validation fails by adding a static attribute message in the model class. Error message. For example:

<?php
namespace appmodel;
use thinkModel;
class Test extends Model
{
    // 指定表名
    protected $table = 'test';
    // 指定主鍵名
    protected $pk = 'id';
    // 自動時間戳
    protected $autoWriteTimestamp = true;

    // 定義驗證規(guī)則
    protected $validate=[
        'name'=>'require|max:10',
        'age'=>'require|integer|between:1,100',
        'email'=>'email',
    ];

    // 定義驗證失敗消息
    protected $message = [
        'name.require'  => '姓名不能為空',
        'name.max'      => '姓名長度不能超過10個字符',
        'age.require'   => '年齡不能為空',
        'age.integer'   => '年齡必須為整數(shù)',
        'age.between'   => '年齡取值必須在1到100之間',
        'email.email'   => ' email格式不正確 ',
    ];
}

In this example, we define the error message for verification failure. If data validation failure is detected, ThinkPHP6 will automatically return the corresponding error information according to the defined message.

Summary

By using the ThinkPHP6 automatic verification function, we can quickly implement ORM automatic verification of database operations, thereby improving development efficiency and reducing errors. Defining data validation rules and message prompts in the model class can help us develop and maintain more conveniently. I hope this article can help everyone and make everyone more comfortable when using ThinkPHP6.
