1. Configure the business domain name in the background of the mini program

2. Write an html on the server to implement the form upload file

3. The back-end php receives the file and saves it to a server folder, and saves the file name to the database for later retrieval

4. Create a page in the WeChat applet and use web-view to upload files;

Detailed implementation:

1. Configure the business domain name in the mini program background

##3. The back-end php receives the file and saves it to a server folder, and saves the file name to the database for later retrieval using

up_file.php file:

 0)  
	  {  
	  echo "错误: " . $_FILES["file"]["error"] . "
";  
	  }  
	else  
	  {  
		$dlog["name"]=$_FILES["file"]["name"];
  		$dlogs=$dlog;	
    	//echo urldecode(json_encode($dlogs));
		$name =$_FILES["file"]["name"];
		echo '上传成功！';
		echo $name;
			//插入数据到数据库 
			$strsql = "insert into name (fileName) values('$name')";
			//mysql_query() 函数执行一条 MySQL 查询。SELECT，SHOW，EXPLAIN 或 DESCRIBE 都需要用这个函数执行
			$result = @mysql_query($strsql);
//	  echo "文件名: " . $_FILES["file"]["name"] . "
";  
//	  echo "类型: " . $_FILES["file"]["type"] . "
";  
//	  echo "大小: " . ($_FILES["file"]["size"] / 1024) . " Kb
";   
	  }  
	 if (file_exists("upload/" . $_FILES["file"]["name"]))  
	    {  
//	      echo $_FILES["file"]["name"] . " 文件已经存在. ";  
	    }  
	else  
	    {  
	      move_uploaded_file($_FILES["file"]["tmp_name"],  
	      "upload/" . $_FILES["file"]["name"]);  
//	      echo "文件已经被存储到: " . "upload/" . $_FILES["file"]["name"];  
	    }   
?>
