Problem description:
I want the client to automatically upload a specific file to the server. Currently, PHP is used.

The code is as follows: index.html






Upload. php
If ($ _ FILES ["file"] ["error"]> 0)
{
Echo "Error:". $ _ FILES ["file"] ["error"]." ";
}
Else
{
Echo "Upload:". $ _ FILES ["file"] ["name"]." ";
$ File_destination = "E:/mnt/upload/". $ _ FILES ["file"] ["name"]; // target file
@ Copy ($ _ FILES ["file"] ["tmp_name"], $ file_destination );
Echo "Stored in:". $ file_destination;
}
?>

Problem:
1. if you want the client to automatically and silently upload a FILE, you do not need to use the webpage. that is, you need to assign a value to the FILE type and click submit automatically. Access the URL in the client program and automatically upload a file.
2. is there any other method besides php to implement the automatic file transfer function ??? Upload input file php
