html simple page:

##index.html code:

<form action="{:U(&#39;index/upload&#39;)}" method="post" enctype="multipart/form-data">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 文件上传：<input type="file" name = "test[]">
 <input type="submit" value = "提交">
</form>

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();
  }
 }
}

Upload result display:

When many people upload multiple files, they finally find that only one file was uploaded. This is mainly due to the naming, because it is the same name, so there is only one picture left in the end

Solution:
First method:

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

Empty saveRule in $config, after uploading The name 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 $config: 'saveName' => array('uniqid', mt_rand(1,999999).'_'.md5(uniqid())),

The last The 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 and convenient method!
