Thinkphp 验证码、文件上传

一、验证码

 

验证码参数

例题:登录时验证下验证码

LoginController.class.php

<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller
{
    public function Login()
    {
        if(empty($_POST))
        {
            $this->display();    
        }    
        else
        {
            //判断验证码是否正确
            $code = $_POST["yzm"];//用户输入的验证码的值
            $verify = new \Think\Verify(); //生成验证码 
            if($verify->check($code))
            {
                if($_POST["uid"]!="")
                {
                    $model = D("users");        
        
                    $uid = $_POST["uid"];
                    $pwd = $_POST["pwd"];
                    
                    $attr = $model->field("Pwd")->find($uid);
                    //echo $attr["pwd"];
                    
                    if($pwd == $attr["pwd"])
                    {
                        session("uid",$uid);
                        $this->success("登录成功","Main");
                    }
                    else
                    {
                        $this->error("登录失败");    
                    }
                }
                else
                {
                    $this->error("登录失败");    
                }
            
            }
            else
            {
                $this->error("验证码错误");    
            }
        }
    }
    
    //生成验证码的操作
    public function yzm()
    {
        $config =    array(   
        'fontSize'    =>    30,    // 验证码字体大小    
        'length'      =>    5,     // 验证码位数 
        //'useNoise'    =>    false, // 关闭验证码杂点
        'imageW'  => 200,//宽度
        'imageH'  => 100,//高度
        //'useZh' => true,//中文验证码
        //'fontttf' => 'Arvo-Regular.ttf',//指定验证码字体
        );
         
        $Verify = new \Think\Verify($config);
        //$Verify->fontttf = '7.ttf';  // 验证码字体使用 ThinkPHP/Library/Think/Verify/ttfs/5.ttf
        $Verify->entry();    
    }

二、文件上传

上传参数

每个文件信息又是一个记录了下面信息的数组,包括:

 

//文件上传
    public function ShangChuan()
    {
         if(empty($_FILES))
         {
             $this->display();     
         }
         else
         {
              $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->mimes = '';
              $upload->rootPath = './Public/';
              $upload->savePath = 'Uploads/'; // 设置附件上传目录
              $upload->saveName = '';//保持上传文件名不变

              
              // 上传文件   
              $info = $upload->upload();
              var_dump($info);
              
              if(!$info)
              {
                   $this->error($upload->getError());
              }
              else
              {
                  // 上传成功 获取上传文件信息
                  foreach($info as $file)
                  {        
                          $url=$file['savepath'].$file['savename'];
                          echo $url;
                          $this->assign("url",$url);
                            $this->display();
                           //$this->success('上传成功!');
                  }
              }

         }    
    }
