MemberController.class控制器代码

<?php

namespace Addons\Card\Controller;

use Addons\Card\Controller\BaseController;        //引入初始化类BaseController

class MemberController extends BaseController {        //继承初始化类BaseController
    var $model;        //定义变量model;
    function _initialize() {        //定义初始化函数
        $this->model = $this->getModel ( 'card_member' );        //使用getModel()函数查询数据库中model表中查询card_member信息，返回数组并交给模板
        parent::_initialize ();        //调用父类初始化
    }
    // 通用插件的列表模型
    public function lists() {
        // 不显示增加按钮
        // $this->assign ( 'add_button', false );
        
        $map ['token'] = get_token ();        //获取当前用户的token，交给数组map
        session ( 'common_condition', $map );        //设置session值    
        
        parent::common_lists ( $this->model );        //显示该模型列表数据
    }
    
    // 通用插件的编辑模型
    public function edit() {
        parent::common_edit ( $this->model );
    }
    
    // 通用插件的增加模型
    public function add() {
        parent::common_add ( $this->model );
    }
    
    // 通用插件的删除模型
    public function del() {
        parent::common_del ( $this->model );
    }
}

上面控制器中common_edit 函数代码阅读

<?php
public function common_edit($model = null, $id = 0, $templateFile = '') {        //什么函数common_edit，默认参数$model为空，$id为0，$templateFile为空
        is_array ( $model ) || $model = $this->getModel ( $model );        //若$model不存在或不是数组，用getModel函数查询数据库，并给$model赋值
        $id || $id = I ( 'id' );        //若$id不存在，给$id赋值为传过来的值
        
        // 获取数据
        $data = M ( get_table_name ( $model ['id'] ) )->find ( $id );        //用get_table_name函数获取表名，并查该id的数据
        $data || $this->error ( '数据不存在！' );        //若无数据，报错
        
        $token = get_token ();        //获取token
        if (isset ( $data ['token'] ) && $token != $data ['token'] && defined ( 'ADDON_PUBLIC_PATH' )) {        //判断数据库中token是否存在，若存在是否与传过来的token对比，并检查常量ADDON_PUBLIC_PATH是否定义
            $this->error ( '非法访问！' );        //抛出错误
        }
        
        if (IS_POST) {    
            $Model = D ( parse_name ( get_table_name ( $model ['id'] ), 1 ) );        //实例化模型
            // 获取模型的字段信息
            $Model = $this->checkAttr ( $Model, $model ['id'] );        //验证$Model
            if ($Model->create () && $Model->save ()) {        //判断并保存数据
                $this->_saveKeyword ( $model, $id );
                
                $this->success ( '保存' . $model ['title'] . '成功！', U ( 'lists?model=' . $model ['name'], $this->get_param ) );
            } else {
                $this->error ( $Model->getError () );
            }
        } else {
            $fields = get_model_attribute ( $model ['id'] );        //获取数据并缓存
            
            $this->assign ( 'fields', $fields );        
            $this->assign ( 'data', $data );
            $this->meta_title = '编辑' . $model ['title'];
            
            $templateFile || $templateFile = $model ['template_edit'] ? $model ['template_edit'] : '';
            $this->display ( $templateFile );        //调用模板显示
        }
    }
