README

这是一个库包，用于在WordPress中使用Laravel的Eloquent ORM。

包安装

要安装此包，请编辑您的composer.json文件

{
    "require": {
        "kaizencoders/wp-eloquent": "dev-master"
    }
}

现在运行

$ composer install

使用示例

基本用法

$db = \KaizenCoders\ORM\Eloquent\Database::instance();

var_dump( $db->table('users')->find(1) );
var_dump( $db->select('SELECT * FROM wp_users WHERE id = ?', [1]) );
var_dump( $db->table('users')->where('user_login', 'john')->first() );

// OR with DB facade
use \KaizenCoders\ORM\Eloquent\Facades\DB;

var_dump( DB::table('users')->find(1) );
var_dump( DB::select('SELECT * FROM wp_users WHERE id = ?', [1]) );
var_dump( DB::table('users')->where('user_login', 'john')->first() );

为自定义表创建模型

您可以使用WordPress数据库的自定义表来创建模型

<?php
namespace Whatever;

use KaizenCoders\ORM\Eloquent\Model;

class CustomTableModel extends Model {

    /**
     * Name for table without prefix
     *
     * @var string
     */
    protected $table = 'table_name';

    /**
     * Columns that can be edited - IE not primary key or timestamps if being used
     */
    protected $fillable = [
        'city',
        'state',
        'country'
    ];

    /**
     * Disable created_at and update_at columns, unless you have those.
     */
    public $timestamps = false;

    /** Everything below this is best done in an abstract class that custom tables extend */

    /**
     * Set primary key as ID, because WordPress
     *
     * @var string
     */
    protected $primaryKey = 'ID';

    /**
     * Make ID guarded -- without this ID doesn't save.
     *
     * @var string
     */
    protected $guarded = [ 'ID' ];

    /**
     * Overide parent method to make sure prefixing is correct.
     *
     * @return string
     */
    public function getTable()
    {
        // In this example, it's set, but this is better in an abstract class
        if ( isset( $this->table ) ){
            $prefix =  $this->getConnection()->db->prefix;
            
            return $prefix . $this->table;
        }

        return parent::getTable();
    }

}

从表中检索所有行

$users = $db->table('users')->get();

foreach ($users as $user) {
    var_dump($user->display_name);
}

在这里，users是表名（不包含前缀）。前缀将自动应用。

其他示例

• 查询
• Eloquent ORM

编写模型

use \WeDevs\ORM\Eloquent\Model as Model;

class Employee extends Model {

}

var_dump( Employee::all()->toArray() ); // gets all employees
var_dump( Employee::find(1) ); // find employee with ID 1

类名Employee将被转换为PREFIX_employees表以运行查询。但通常，您可以重写表名。

WordPress内建模型

• 帖子
• 评论
• 帖子元数据
• 用户
• 用户元数据

use WeDevs\ORM\WP\Post as Post;

var_dump( Post::all() ); //returns only posts with WordPress post_type "post"

通过post_status和post_type过滤Post

use WeDevs\ORM\WP\Post as Post;
var_dump(Post::type('page')->get()->toArray()); // get pages
var_dump(Post::status('publish')->get()->toArray()); // get posts with publish status
var_dump(Post::type('page')->status('publish')->get()->toArray()); // get pages with publish status

工作原理

• Eloquent主要用作查询构建器
• WPDB用于运行由Eloquent构建的查询
• 因此，我们可以使用类似debug-bar或query-monitor的插件来获取SQL查询报告。
• 它不会创建任何额外的MySQL连接

最低要求

• PHP 5.6.4+
• WordPress 4.0+
