夺命雷公狗---Thinkphp----12之文章的增删改查（图片上传和关联查询）
我们由于表分析的不够完善，所以我们来加多一个tid的字段，到时候主要目的是为了更好的遍历出文章是属于那个分类下的，表如下所示：
那么下一步我们就开始创建一个ArticleController.class.php的控制器，用来管理文章的增删改查操作，所以我们开始第一步来实现文章的添加，我们先来实现他的增加功能：
public function add(){ if(IS_POST){ $data['title'] = I('title'); $data['tid'] = I('tid'); $data['new'] = I('new'); $data['hot'] = I('hot'); $data['zuozhe'] = I('zuozhe'); $data['content'] = I('content'); if($_FILES['pic']['tmp_name']!=''){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './'; //这个一定要加否则很容易中招 $upload->savePath = 'Public/Uploads/'; // 设置附件上传目录 $info = $upload->uploadOne($_FILES['pic']); if($info){ //这里组装sql语句，让图片融入$data['pic']里面 $data['pic'] = $info['savepath'].$info['savename']; }else{ $this->error($upload->getError()); } } //var_dump($_FILES); $mod = D('Article'); if(!empty($data['tid']) or $data['tid'] != '0'){ if($mod->create($data)){ if($mod->add()){ $this->success('添加文章成功',U('Article/lists')); }else{ $this ->error('添加文章失败'); } }else{ $this -> error($mod->getError()); } }else{ $this ->error('请选择所属分类'); } }
让后就是因为我们在上传时候要了tp的自动验证所以我们要在model目录下创建一个ArticleModel.class.php的文件，主要用来处理不让人可以不填写就之间发表文章，代码如下所示：
<?php namespace Admin\Model; use Think\Model; class ArticleModel extends Model{ protected $_validate = array( array('title','require','文章标题必须填写'), //默认情况下用正则进行验证 array('zuozhe','require','文章作者必须填写'), //默认情况下用正则进行验证 array('content','require','文章内容必须填写'), //默认情况下用正则进行验证 array('title','','该文章标题已存在',0,'unique',1), // 在新增的时候验证name字段是否唯一 ); }
视图的代码如下所示：

然后就到查询了，这个其实很简单，直接在以前的基础上套用以下即可实现，控制器代码如下所示：
public function lists(){ //1.显示分页工具条 $mod = M('Article'); $totalRows = $mod->table("jj_article a, jj_type t")->where('a.tid=t.id')->count(); //创建分页对象时，分页对象需要总记录数和分页条数 $page = new \Think\Page($totalRows,2); $page -> rollPage =5; //分页列表上显示多少条 $page->setConfig('theme','%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END% %HEADER%'); $page->setConfig('first','首页'); $page->setConfig('prev','上一页'); $page->setConfig('next','下一页'); $page->setConfig('last','尾页'); $pageHtml = $page -> show();//生成分页的连接诶效果（分页工具条的html代码） $this -> assign('pageHtml',$pageHtml);//分配分页栏到模版 //2.查询出当前页面的列表数据 $article = $mod->page(I('get.p',1),$page->listRows)-> field('a.id,a.title,a.pic,a.zuozhe,a.new,a.hot,t.typename')-> table("jj_article a, jj_type t")-> where('a.tid=t.id')-> select(); //dump($article); $this -> assign('article',$article); $this -> display(); }
然后直接在列表页遍历出来问题即可解决，不过在这里设计到一点点的if判断的技巧了：

展示效果如下所示：
然后就到文章编辑了，这里也是文章系统里面难度西数较大的一个地方，因为这里其中一个难点就是选择菜单的的那里，如下所示：
其实思路也是很简单的，我们平常时候怎么查询数据表的，那么我们就怎么来查询他问题即可解决：
我们查询的第一张表里面就只有一个tid，这也是正常的，我们直接将他分配到前端的模版里面即可。。
然后查询的是第二张表，这张表里面只有id和typename，我们也将他查询出来，然后在模版里直接遍历。
思路：直接遍历type表的数据，再通过判断来获取到自己所选址的字段然后通过selected=“selected” 来选中即可：
废话不多说，直接公布代码：
public function edit(){ $id = I('id'); $mod = M('Article'); $amod = $mod->find($id); $this ->assign('amod',$amod); //dump($amod); //这里主要是为了获取type表的id $bm = M('Type')->select(); //dump($bm); $this -> assign('bm',$bm); if(IS_POST){ $data['title'] = I('title'); $data['tid'] = I('tid'); $data['new'] = I('new'); $data['hot'] = I('hot'); $data['zuozhe'] = I('zuozhe'); $data['pic'] = I('pic'); $data['content'] = I('content'); $data['id'] = $id; if($_FILES['pic']['tmp_name']!=''){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './'; //这个一定要加否则很容易中招 $upload->savePath = 'Public/Uploads/'; // 设置附件上传目录 $info = $upload->uploadOne($_FILES['pic']); if($info){ //先查找到原先图片所在的位置，直接对他删除 $ypic = M('Article')->find($id); unlink($ypic['pic']); //这里组装sql语句，让图片融入$data['pic']里面 $data['pic'] = $info['savepath'].$info['savename']; } }else{ $cmod = M('Article')->find($id); $data['pic'] = $cmod['pic']; } $artmod = D('Article'); if($artmod->create($data,1)){ if($artmod->save()){ $this->success('编辑文章成功',U('Article/lists'),1); }else{ $this->error('您还没有任何修改噢',U('Article/lists')); } }else{ $this->error($artmod->getError()); } } $this -> display(); }
不过在编辑这块里面其实可以删除下原图的，如果用户不上传，那么我们可以通过直接按照id 查询下是否为空，如果不为空再上传：
那么下一步就是视图下的代码了，

在编辑里面记得要用input 的hidden多带个id的方式噢，不然在控制器里将步步维艰。。
删除这个其实也是最简单的这个了，直接在列表页里留一个id通过get方式传送到后端问题即可解决：
然后在后台直接对她进行接收然后删除问题即可解决：
public function del(){ $id = I('id'); if(M('User')->delete($id)){ $this -> success('删除成功',U('User/lists')); }else{ $this -> error("删除失败"); } }
