can anybody tell me how i can upload a file without user interaction.the file full path is known and can be hardcoded.
Uploading from Client to Server
I'm assuming that you want to upload a file from a client to your server. The client being the web browser.
This is not possible under normal security conditions on the major browsers.
It can only be achieved if the browser settings have been changed to allow a certain website to upload automatically. Such as in an intranet.
On a normal browser, the DOM node representing the upload field has a value that is read only. So you cannot write a file path to it.
Even if you have the following:
[HTML]
[/HTML]
The value will not be set to the file input.
This really is a browser issue, not a PHP one. It restricts any client side script language that accesses the DOM, such as JavaScript, Actionscript, VBScript etc.
I haven't tested on ActionScript or VBScript though.
Uploading from Server to Server
If you instead wanted to upload a file from a remote server to your server using PHP, then it is very simple.
[PHP]
<?php
$contents = file_get_contents('http://example.com/file.zip');
?>[/PHP]
That would download the imaginary file 'http://example.com/file.zip' to your php application via a TCP socket.
Then you can write the file to your filesystem:
<?php
$contents = file_get_contents('http://example.com/file.zip');
$fp = fopen('/path/to/file.zip', 'wb');
fwrite($fp, $contents, strlen($contents));
fclose($fp);
?>
That will write the file to '/path/to/file.zip'.
