上传文件

<?php
namespace HomeController;
use ThinkController;
 
class DocumentController extends Controller
{
    function xianshi(){
        if(empty($_FILES))
        {
            $this->display();    
            }
        else
        {
            $upload=new ThinkUpload();
            //设置上传文件参数
            $upload->maxSize=1024000;//文件大小
            $upload->exts=array('jpg',"png","gif","jpeg");//文件类型
            $upload->rootPath="./Public";
            $upload->savePath="uploads/";//上传路径，必须是这样写，基于根路径
            $upload->saveName='time';
            //上传方法
            $info=$upload->upload();
            var_dump($info);
            }
        }
    }

前台:

<body>
<form action="__ACTION__" method="post" enctype="multipart/form-data">
<input type="file" name="file" />
<input type="submit"  value="上传"/>
</form>
</body>
