视频教程:https://www.bilibili.com/video/BV1Ee41197RX/ 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=1733797287&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:5wvDFASPrYSMdBIGrlNkluU4I9M=) ## 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; /** * 排除前台提交过来的字段 * @param $params * @return array */ protected function preExcludeFields($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; } /** * 添加 * * @return string * @throws \think\Exception */ public function add() { if (false === $this->request->isPost()) { return $this->view->fetch(); } $params = $this->request->post('row/a'); if (empty($params)) { $this->error(__('Parameter %s can not be empty', '')); } $params = $this->preExcludeFields($params); if ($this->dataLimit && $this->dataLimitFieldAutoFill) { $params[$this->dataLimitField] = $this->auth->id; } $result = false; Db::startTrans(); try { //是否采用模型验证 if ($this->modelValidate) { $name = str_replace("\\model\\", "\\validate\\", get_class($this->model)); $validate = is_bool($this->modelValidate) ? ($this->modelSceneValidate ? $name . '.add' : $name) : $this->modelValidate; $this->model->validateFailException()->validate($validate); } $result = $this->model->allowField(true)->save($params); Db::commit(); } catch (ValidateException|PDOException|Exception $e) { Db::rollback(); $this->error($e->getMessage()); } if ($result === false) { $this->error(__('No rows were inserted')); } $this->success(); } /** * 编辑 * * @param $ids * @return string * @throws DbException * @throws \think\Exception */ public function edit($ids = null) { $row = $this->model->get($ids); if (!$row) { $this->error(__('No Results were found')); } if (false === $this->request->isPost()) { $this->view->assign('row', $row); return $this->view->fetch(); } $params = $this->request->post('row/a'); if (empty($params)) { $this->error(__('Parameter %s can not be empty', '')); } $params = $this->preExcludeFields($params); $result = false; Db::startTrans(); try { //是否采用模型验证 if ($this->modelValidate) { $name = str_replace("\\model\\", "\\validate\\", get_class($this->model)); $validate = is_bool($this->modelValidate) ? ($this->modelSceneValidate ? $name . '.edit' : $name) : $this->modelValidate; $row->validateFailException()->validate($validate); } $result = $row->allowField(true)->save($params); Db::commit(); } catch (ValidateException|PDOException|Exception $e) { Db::rollback(); $this->error($e->getMessage()); } if (false === $result) { $this->error(__('No rows were updated')); } $this->success(); } /** * 删除 * * @param $ids * @return void * @throws DbException * @throws DataNotFoundException * @throws ModelNotFoundException */ public function del($ids = null) { if (false === $this->request->isPost()) { $this->error(__("Invalid parameters")); } $ids = $ids ?: $this->request->post("ids"); if (empty($ids)) { $this->error(__('Parameter %s can not be empty', 'ids')); } $pk = $this->model->getPk(); $list = $this->model->where($pk, 'in', $ids)->select(); $count = 0; Db::startTrans(); try { foreach ($list as $item) { $count += $item->delete(); } Db::commit(); } catch (PDOException|Exception $e) { Db::rollback(); $this->error($e->getMessage()); } if ($count) { $this->success(); } $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=1733797287&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:kDwP2b7piv_0RaIRCo8bNO5LFZA=) 其他两个文件无需修改,index.html改完的代码如下: ```html
{include file="common/sidenav" /}
测试表格
{:__('Add')}
{:__('Edit')}
{:__('Delete')}
``` ### 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
测试表格
``` ![](https://resource.maoshu.fun/storage/default/20241010/image7d89a06f0782400828e51da298b5f0e0f97d58b6.png?e=1733797287&token=Ov7mXAv_8azPtTTXXyhh0S5qpDFEhafGpHARTAg2:pRTPRFXstZ2WsfePefe4jil422g=) ### 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 request->filter('trim,strip_tags,htmlspecialchars'); $modulename = $this->request->module(); $controllername = Loader::parseName($this->request->controller()); $actionname = strtolower($this->request->action()); // 检测IP是否允许 check_ip_allowed(); // 定义是否Dialog请求 !defined('IS_DIALOG') && define('IS_DIALOG', input("dialog") ? true : false); // 如果有使用模板布局 if ($this->layout) { $this->view->engine->layout('layout/' . $this->layout); } $this->auth = Auth::instance(); // token $token = $this->request->server('HTTP_TOKEN', $this->request->request('token', \think\Cookie::get('token'))); $path = str_replace('.', '/', $controllername) . '/' . $actionname; // 设置当前请求的URI $this->auth->setRequestUri($path); // 检测是否需要验证登录 if (!$this->auth->match($this->noNeedLogin)) { //初始化 $this->auth->init($token); //检测是否登录 if (!$this->auth->isLogin()) { $this->error(__('Please login first'), 'index/user/login'); } // 判断是否需要验证权限 if (!$this->auth->match($this->noNeedRight)) { // 判断控制器和方法判断是否有对应权限 if (!$this->auth->check($path)) { $this->error(__('You have no permission')); } } } else { // 如果有传递token才验证是否登录状态 if ($token) { $this->auth->init($token); } } $this->view->assign('user', $this->auth->getUser()); // 语言检测 $lang = $this->request->langset(); $lang = preg_match("/^([a-zA-Z\-_]{2,10})\$/i", $lang) ? $lang : 'zh-cn'; $site = Config::get("site"); $upload = \app\common\model\Config::upload(); // 上传信息配置后 Hook::listen("upload_config_init", $upload); // 配置信息 $config = [ 'site' => array_intersect_key($site, array_flip(['name', 'cdnurl', 'version', 'timezone', 'languages'])), 'upload' => $upload, 'modulename' => $modulename, 'controllername' => $controllername, 'actionname' => $actionname, 'jsname' => 'frontend/' . str_replace('.', '/', $controllername), 'moduleurl' => rtrim(url("/{$modulename}", '', false), '/'), 'language' => $lang ]; $config = array_merge($config, Config::get("view_replace_str")); Config::set('upload', array_merge(Config::get('upload'), $upload)); // 配置信息后 Hook::listen("config_init", $config); // 加载当前控制器语言包 $this->loadlang($controllername); $this->assign('site', $site); $this->assign('config', $config); } /** * 加载语言文件 * @param string $name */ protected function loadlang($name) { $name = Loader::parseName($name); $name = preg_match("/^([a-zA-Z0-9_\.\/]+)\$/i", $name) ? $name : 'index'; $lang = $this->request->langset(); $lang = preg_match("/^([a-zA-Z\-_]{2,10})\$/i", $lang) ? $lang : 'zh-cn'; Lang::load(APP_PATH . $this->request->module() .
