Controller IndexController.class.php Code:

<?php
namespace Home\Controller;use Think\Controller;class IndexController extends Controller {    
    public function index(){        
    $this->display();
    }    
    public function upload(){        
        if(IS_POST){            
        $config = array(                
              &#39;maxSize&#39;    =>    3145728,
                &#39;rootPath&#39;   =>    &#39;./Uploads/&#39;,
                &#39;savePath&#39;   =>    &#39;&#39;,
                &#39;saveName&#39;   =>    array(&#39;uniqid&#39;, mt_rand(1,999999).&#39;_&#39;.md5(uniqid())),
                &#39;exts&#39;       =>    array(&#39;jpg&#39;, &#39;gif&#39;, &#39;png&#39;, &#39;jpeg&#39;),
                &#39;autoSub&#39;    =>    true,
                &#39;subName&#39;    =>    array(&#39;date&#39;,&#39;Ymd&#39;),
            );            
            $upload = new \Think\Upload($config);// 实例化上传类
                  $info   =   $upload->upload();            
                  if(!$info) {                
                  $this->error($upload->getError());
            }else{                
                foreach($info as $file){                    
                echo $file[&#39;savepath&#39;].$file[&#39;savename&#39;];
                }
            }
        }else{            
            $this->display();
        }
    }
}

The upload result shows:

When many people are uploading multiple files, In the end, I found that I only uploaded one picture, mainly because of the naming. Because it was the same name, there was only one picture left in the end.

Solution: The first one:

##

$config = array(                
                'maxSize'    =>    3145728,
                'rootPath'   =>    './Uploads/',
                'exts'       =>    array('jpg', 'gif', 'png', 'jpeg'),
                'autoSub'    =>    true,
                'subName'    =>    array('date','Ymd'),
                'saveRule'   => '',
            );

Leave the saveRule in $config blank, and the name after uploading is: 59c8d38cdb968.jpg

If you feel that this naming is unreliable, you can adopt the second method:

$config = array(                
                'maxSize'    =>    3145728,
                'rootPath'   =>    './Uploads/',
                'saveName'   =>    array('uniqid', mt_rand(1,999999).'_'.md5(uniqid())),
                'exts'       =>    array('jpg', 'gif', 'png', 'jpeg'),
                'autoSub'    =>    true,
                'subName'    =>    array('date','Ymd'),
            );

Set in $config: 'saveName' => array('uniqid', mt_rand(1,999999).'_'.md5(uniqid()) ),

The final result is similar to: 672563_30ad4d8a2aafc832363de8edc1940b5c59c8d44a303f9.jpg

##Of course, the naming can be modified as needed. There are many ways to upload multiple files, here is just a simple one Convenient method!
