thinkphp implements image upload function

There is a very important point here, that is, it is very important to add enctype="multipart/form-data" to the form item, because this is the type that allows you to upload. If there is no him, then It cannot be uploaded. I will explain the other types of enctype in future articles. Here we create a new php file AddAction.class.php, the code is as follows; Many Java users usually use concatenation of two strings, so this is easy to confuse.

The above is an introduction to the implementation code of thinkphp image upload function to help everyone better learn and master PHP programming.

class AddAction extends Action{ 
 /** 
 * 说明：ThinkPHP文件上传测试函数 
 * 版本：1.0 

 */ 
 public function addChk(){ 
   //导入图片上传类 
   import("ORG.Net.UploadFile"); 
   //实例化上传类 
   $upload = new UploadFile(); 
   $upload->maxSize = 3145728; 
   //设置文件上传类型 
   $upload->allowExts = array('jpg','gif','png','jpeg'); 
   //设置文件上传位置 
   $upload->savePath = "./Public/Uploads/";//这里说明一下，由于ThinkPHP是有入口文件的，所以这里的./Public是指网站根目录下的Public文件夹 
   //设置文件上传名(按照时间) 
   $upload->saveRule = "time"; 
   if (!$upload->upload()){ 
    $this->error($upload->getErrorMsg()); 
   }else{ 
    //上传成功，获取上传信息 
    $info = $upload->getUploadFileInfo(); 
   } 
 
   //保存表单数据，包括上传的图片 
   $game = M("Game"); 
   $game->create(); 
   $savename = $info[0]['savename']; 
   //$savepath = $info[0]['savepath']; 
   //$aa = $savepath.$savename; 
   //dump($aa); 
   $imgurl = "http://demo.dutycode.com/Public/Uploads/".$savename;//这里是设置文件的url注意使用.不是+ 
   //dump($imgurl); 
   $data['gamename'] = $_POST['gamename']; 
   $data['gameimg'] = $imgurl; 
   $data['gameinfo'] = $_POST['gameinfo']; 
   $data['gamelink'] = $_POST['gamelink']; 
   $data['publishtime'] = date("Y-m-d H:i:s"); 
   $res = $game->add($data);//写入数据库 
   if ($res){ 
    $this->redirect("addGame","",2,"添加成功！两秒后跳回"); 
   }else{ 
    $this->redirect("addGame","",2,"失败！两秒后跳回"); 
   } 
}
