第一先创建数据库：
create table `bk_article`(
`id` mediumint(9) auto_inctement primary key,
`title` varchar(40),
`cateid` mediumint(9) comment‘栏目第’,
`kewords` varchar(30) comment'关键词',
`desc` varchar(225) comment'描述',
`author` varchar(60) comment'作者',
`thumb` varchar(255) not null comment'图片',
`comtent` text not null comment'内容',
`click` mediument(9) comment'点击',
`zan` mediument(9) comment'点赞',
`rec` tinyint(1) comment'0推荐，1不推荐',
`time` int(10) comment'时间'
)这里需要注意的是图片的上传和修改删除在模型中定义路径，
先创建目录引入文件，然后控制器中Admin.php:
<?php
namespace app\admin\controller;
use app\admin\model\Cate as CateModel;
use app\admin\model\Article as ArticleModel;
use app\admin\controller\Common;
class Article extends Common
{
public function lst(){
$artres=db('article')->field('a.*,b.catename')->alias('a')->join('bk_cate b','a.cateid=b.id')->order('a.id desc')->paginate(10);
$this->assign('artres',$artres);
return view();
}
public function add(){
if(request()->isPost()){
$data=input('post.');
$data['time']=time();
$validate = \think\Loader::validate('Article');
if(!$validate->scene('add')->check($data)){
$this->error($validate->getError());
}
$article=new ArticleModel();
if($article->save($data)){
$this->success('添加文章成功',url('lst'));
}else{
$this->error('添加文章失败！');
}
return;
}
$cate=new CateModel();
$cateres=$cate->catetree();
$this->assign('cateres',$cateres);
return view();
}
public function edit(){
if(request()->isPost()){
$data=input('post.');
$validate = \think\Loader::validate('Article');
if(!$validate->scene('edit')->check($data)){
$this->error($validate->getError());
}
$article=new ArticleModel;
$save=$article->update($data);
if($save){
$this->success('修改文章成功！',url('lst'));
}else{
$this->error('修改文章失败！');
}
return;
}
$cate=new CateModel();
$cateres=$cate->catetree();
$arts=db('article')->where(array('id'=>input('id')))->find();
$this->assign(array(
'cateres'=>$cateres,
'arts'=>$arts,
));
return view();
}
public function del(){
if(ArticleModel::destroy(input('id'))){
$this->success('删除文章成功！',url('lst'));
}else{
$this->error('删除文章失败！');
}
}
模型层model/Admin.php：
<?php
namespace app\admin\model;
use think\Model;
class Article extends Model
{
protected static function init()
{
Article::event('before_insert',function($article){
if($_FILES['thumb']['tmp_name']){
$file = request()->file('thumb');
$info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
if($info){
//$thumb=ROOT_PATH . 'public' . DS . 'uploads'.'/'.$info->getExtension();
$thumb= '/11/'.'public'.DS.'uploads'.'/'.$info->getSaveName();
$article['thumb']=$thumb;
}
}
});
Article::event('before_update',function($article){
if($_FILES['thumb']['tmp_name']){
$arts=Article::find($article->id);
$thumbpath=$_SERVER['DOCUMENT_ROOT'].$arts['thumb'];
if(file_exists($thumbpath)){
@unlink($thumbpath);
}
$file = request()->file('thumb');
$info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
if($info){
//$thumb=ROOT_PATH . 'public' . DS . 'uploads'.'/'.$info->getExtension();
$thumb= '/11/'.'public'.DS.'uploads'.'/'.$info->getSaveName();
$article['thumb']=$thumb;
}
}
});
Article::event('before_delete',function($article){
$arts=Article::find($article->id);
$thumbpath=$_SERVER['DOCUMENT_ROOT'].$arts['thumb'];
if(file_exists($thumbpath)){
@unlink($thumbpath);
}
});
}
}
验证：validate/Admin.php
<?php
namespace app\admin\validate;
use think\Validate;
class Article extends Validate
{
protected $rule=[
'title'=>'unique:article|require',
'cateid'=>'require',
'content'=>'require',
];
protected $message=[
'title.require'=>'文章标题不得为空！',
'title.unique'=>'文章标题不得重复！',
// 'title.max'=>'文章标题长度大的大于25个字符！',
'cateid.require'=>'文章所属栏目不得为空！',
'content.require'=>'文章内容不得为空！',
];
protected $scene=[
'add'=>['title','cateid','content'],
'edit'=>['title','cateid'],
];
模板文件中要只有列表输出的用法
lst.htm:
{volist name="artres" id="art"}
<tr>
<td align="center">{$art.id}</td>
<td><?php echo mb_substr($art['title'], 0,9,'utf-8'); if(strlen($art['title'])>9){echo '...';}?></td>
<td align="center">
{if condition="$art['thumb'] neq ''"}
<img src="{$art.thumb}" height="30">
{else /}
暂无缩略图
{/if}
</td>
<td align="center">{if condition="$art['author'] eq ''"}未填写{else /}{$art.author}{/if}</td>
<td align="center">{if condition="$art['rec'] eq 0"}未推荐{else /}已推荐{/if}</td>
<td align="center">{$art.catename}</td>
<td align="center">
<a href="{:url('edit',array('id'=>$art['id']))}" class="btn btn-primary btn-sm shiny">
<i class="fa fa-edit"></i> 编辑
</a>
<a href="#" onClick="warning('确实要删除吗', '{:url('del',array('id'=>$art['id']))}')" class="btn btn-danger btn-sm shiny">
<i class="fa fa-trash-o"></i> 删除
</a>
</td>
</tr>
{/volist}
分页：{$artres->render()}
