如图所示，在前台会员中心增加一个表格，功能和后台的一模一样，具有新增 修改 删除 批量删除 搜索 分页 等完整功能！

![](https://resource.maoshu.fun/storage/default/20241010/imagec490725e31d0802ca8adb35f99cdfa8a5d5deb08.png?e=1732495867&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:gtZDLyaKbA8Q-NwFsBfPMXsrW4o=)

## 实现逻辑：
一个字：“**复制**”！

先在后台一键crud生成表格，然后在前台对应位置复制粘贴对应的功能即可！当然有一些地方是要修改的，否则会报方法错误！

### 1.新建数据表fa_ceshi，然后一键crud
这个很简单，不做具体演示了。

下面的例子里，我们这里生成的是Ceshi，前台要增加的是Mstable。

### 2.新建模型 Mstable.php
在index文件夹下，新建文件夹model，然后在model文件夹下新建Mstable.php文件，作为模型，复制上面生成的模型文件，注意修改namespace为 namespace app\index\model ，table表名为 mstable。

代码如下：

```php
namespace app\index\model;
use think\Model;
class Mstable extends Model
{
    // 表名
    protected $name = 'mstable';
    
    // 自动写入时间戳字段
    protected $autoWriteTimestamp = 'integer';
    // 定义时间戳字段名
    protected $createTime = 'createtime';
    protected $updateTime = 'updatetime';
    protected $deleteTime = false;
    // 追加属性
    protected $append = [];
}
```

### 3.新建控制器Mstable.php
在index->controller文件夹下新建Mstable.php文件，作为控制器，然后接下来是复制代码。

首先要复制一个会员中心的user控制器代码；

然后去`application/admin/library/traits/Backend.php`里面复制`index add edit del` 方法到当前控制器里，这里需要注意，一定要删除关于管理员验证的一些代码，具体我们在视频里有讲解；

然后我们需要在_initialize里加上model：

`$this->model = new \app\index\model\Mstable;`
 
最后一定记得引入需要的东西
```php
use Exception;
use think\Db;
use think\exception\DbException;
use think\exception\PDOException;
use think\exception\ValidateException;
use think\response\Json;
```

最终的控制器代码如下：
```php

namespace app\index\controller;
use app\common\controller\Frontend;
use Exception;
use think\Db;
use think\exception\DbException;
use think\exception\PDOException;
use think\exception\ValidateException;
use think\response\Json;
class Mstable extends Frontend
{
    protected $layout = 'default';
    protected $noNeedLogin = [];
    protected $noNeedRight = ['*'];
    protected $model = null;
    public function _initialize()
    {
        parent::_initialize();
        // $auth = $this->auth;
        $this->model = new \app\index\model\Mstable;
    }
    /**
     * 查看
     *
     * @return string|Json
     * @throws \think\Exception
     * @throws DbException
     */
    public function index()
    {
        //设置过滤方法
        $this->request->filter(['strip_tags', 'trim']);
        if (false === $this->request->isAjax()) {
            $this->view->assign('title', "表格");
            return $this->view->fetch();
        }
        //如果发送的来源是 Selectpage，则转发到 Selectpage
        if ($this->request->request('keyField')) {
            return $this->selectpage();
        }
        [$where, $sort, $order, $offset, $limit] = $this->buildparams();
        $list = $this->model
            ->where($where)
            ->order($sort, $order)
            ->paginate($limit);
        $result = ['total' => $list->total(), 'rows' => $list->items()];
        return json($result);
    }
    /**
     * 前台提交过来,需要排除的字段数据
     */
    protected $excludeFields = "";
     /**
     * 是否开启Validate验证
     */
    protected $modelValidate = false;
    /**

    protected function preExcludeFields($params)
    {
        if (is_array($this->excludeFields)) {
            foreach ($this->excludeFields as $field) {
                if (array_key_exists($field, $params)) {
                    unset($params[$field]);
                }
            }
        } else if (array_key_exists($this->excludeFields, $params)) {
            unset($params[$this->excludeFields]);
        }
        return $params;
    }
     /**

        }
        $this->error(__('No rows were deleted'));
    }
}
```

### 4.新建视图（html代码）
在index的view文件夹下新建文件夹mstable，然后把后台ceshi里的index.html add.html和edit.html文件复制进来，index.html里删除关于auth验证的代码。

![](https://resource.maoshu.fun/storage/default/20241010/image003467cad75038e72d21005eb68cee4e62a4eae7.png?e=1732495867&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:LLYIyr3QL4dQN2sA-hQ8c3dlBHQ=)

其他两个文件无需修改，index.html改完的代码如下：
```html

<div id="content-container" class="container">
    <div class="row">
        <div class="col-md-3">
            {include file="common/sidenav" /}
        </div>
        <div class="col-md-9">
            <div class="panel panel-default">
                <div class="panel-body">
                    <h2 class="page-header">测试表格</h2>
                    <div id="myTabContent" class="tab-content">
                        <div class="tab-pane fade active in" id="one">
                            <div class="widget-body no-padding">
                                <div id="toolbar" class="toolbar">
                                    <a href="javascript:;" class="btn btn-primary btn-refresh" title="{:__('Refresh')}" ><i class="fa fa-refresh"></i> </a>
                                    <a href="javascript:;" class="btn btn-success btn-add" title="{:__('Add')}" ><i class="fa fa-plus"></i> {:__('Add')}</a>
                                    <a href="javascript:;" class="btn btn-success btn-edit btn-disabled disabled" title="{:__('Edit')}" ><i class="fa fa-pencil"></i> {:__('Edit')}</a>
                                    <a href="javascript:;" class="btn btn-danger btn-del btn-disabled disabled" title="{:__('Delete')}" ><i class="fa fa-trash"></i> {:__('Delete')}</a>
                                    
            
                                    
            
                                    
                                </div>
                                <table id="table" class="table table-striped table-bordered table-hover table-nowrap"
                                    data-operate-edit="true"
                                    data-operate-del="true"
                                       width="100%">
                                </table>
                            </div>
                        </div>
            
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
```

### 5.新建js文件

在文件夹public/assets/js/frontend下新建mstable.js文件，把后台生成的ceshi.js复制进来，把里面的ceshi改为mstable即可

### 6.修改左侧菜单栏
在会员中心左侧的菜单栏内加入当前的菜单，application/index/view/common/sidenav.html，加入如下代码：
```html

<li class="list-group-item {:check_nav_active('mstable/index')}"> <a href="{:url('mstable/index')}"><i class="fa fa-user-circle fa-fw"></i> 测试表格</a> </li>
```

### 7.修改Frontend文件
`application/common/controller/Frontend.php`

这里面要改的东西比较多，我们在视频内详细说明，下面是改完后的代码：
```php

### 8.去除添加和修改里面的多余页头页尾
修改文件：application/index/view/layout/default.html

在需要去除的地方加上判断 {if !IS_DIALOG}，如下图所示，主要是在头部和尾部加判断

![](https://resource.maoshu.fun/storage/default/20241010/imagef45722b7316a8d328f753343d5227ada5f8b1f20.png?e=1732495867&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:oJ2LSsmacA3VUhay1izSVMBPoy8=)

其中的IS_DIALOG是因为我们在基类里加了常量，如果不加就会报错
```php

// 定义是否Dialog请求
        !defined('IS_DIALOG') && define('IS_DIALOG', input("dialog") ? true : false);
```

好了，现在所有的功能就完成了，快去试试吧，文字能力有限，有不明白的地方看视频讲解。
