两周没有写博客了，这两周主要是在学习thinkPHP5，主要以看视频为主的学习，今天就是对thinkPHP5做一定的总结；
总体来说thinkPHP学习上还是比较顺利；
学习手册--https://www.kancloud.cn/manual/thinkphp5/
thinkPHP5快速手册以及完整手册；
用Composer下载目录：
对应项目目录
控制器的写法：
<?php
namespace app\admin\controller;
use think\Controller;
use think\Db;
use think\Loader;
use app\admin\model\Admin as AdminModel;
class Admin extends Controller
{
public function lst()
{
$list = AdminModel::paginate(3);
$this->assign('list',$list);
return $this->fetch();
}
public function add()
{
if(request()->isPost()){
$data = [
'username'=>input('username'),
'password'=>md5(input('password')),
];
$validate =Loader::validate('Admin');
if(!$validate->scene('add')->check($data)){
$this->error($validate->getError());
}
if(Db::name('admin')->insert($data)){
return $this->success('添加管理者成功','lst');
}else{
return $this->error('添加管理员失败');
}
}
return $this->fetch();
}
public function edit()
{
$id = input('id');
$admins = db('admin')->find($id);
$this->assign("admins",$admins);
if(request()->isPost()){
$data = [];
if(input('password')===""){
$data = [
'id'=>$id,
'username'=>input('username'),
'password'=>$admins['password'],
];
}else{
$data = [
'id'=>$id,
'username'=>input('username'),
'password'=>md5(input('password')),
];
}
$validate =Loader::validate('Admin');
if(!$validate->scene('add')->check($data)){
$this->error($validate->getError());
}
if(Db::name('admin')->update($data)){
return $this->success('编辑管理者成功','lst');
}else{
return $this->error('编辑管理员失败');
}
}
return $this->fetch();
}
public function del()
{
$id = input('id');
if($id!=1){
if(Db::name('admin')->delete($id)){
return $this->success("删除成功",'lst');
}else{
return $this->error("删除管理员失败！",'lst');
}
}else{
return $this->error("系统管理员不能删除",'lst');
}
}
public function logout(){
session("username",'');
session("uid","");
return $this->fetch('login/index');
}
}
视图层代码：
<?php
namespace app\admin\model;
use think\Model;
use think\Db;
use think\Session;
class Admin extends Model{
public function login($data){
$user = Db::name('admin')->where('username','=',$data['username'])->find();
if($user){
if($user['password']==md5($data['password'])){
session("username",$user['username']);
session("uid",$user['id']);
return 3; //信息正確
}else{
return 2; // 密碼錯誤
}
}else{
return 1; // 用戶不存在
}
}
}校验过滤：
<?php
namespace app\admin\validate;
use think\Controller;
use think\Validate;
class Admin extends Validate{
protected $rule = [
'username' =>'require|min:5|unique:admin',
'password' =>'require|min:6',
'id' => 'require',
];
protected $message = [
'username.require' => '管理员名称必须填写',
'password.require' => '管理员密码不能为空',
'username.min' => '管理员名称不能小于6位',
'username.unique' => '管理员名称不得重复',
'password.min' => '管理员密码不能小于6位',
'id.require' => '管理员密码不能小于6位',
];
protected $scene = [
'add' => ['username','password'],
'edit' => ['id','username'],
];
