Question

I’m trying to get PHP to move an uploaded file from the tmp directory to somewhere permanent on my webserver. It seems simple enough, but I’m getting this error:

Unable to move 'C:\UniServer\tmp\php3F62.tmp' to 'static/images/slides/1/1.jpg'

Pretty straight-forward, right? It can’t find the destination folder.

My question is: How do I reference the desired target directory?

Is the reference relative to the script’s position on the server? Or is it relative to the URL? Or the PHP DOCUMENT_ROOT? Or the OS’s filesystem? Or something else?

I can’t find the answer in the PHP documentation or indeed in any of the similar questions here on SO..

Can anyone help? Thanks.

A simple way to keep track of the path is just to define the absolute path in your index.php

define ('SITE_ROOT', realpath(dirname(__FILE__)));

Then just use it like:

move_uploaded_file($_FILES['file']['tmp_name'], SITE_ROOT.'/static/images/slides/1/1.jpg');
