scusami ma avrei un altro piccolo problema...
devo caricare sempre lo stesso file con lo stesso nome e mi da un errore e penso che sia qui:

codice:
If(!in_array($ext, $allow_types)) {
							
				$error.= "Invalid extension for your file: ".$_FILES['file']['name'][$i].", only ".$types." are allowed.
Your file(s) were not uploaded.
";
							
				//Check the size of each file
							
			} Elseif($size > $max_bytes) {
				
				$error.= "Your file: ".$_FILES['file']['name'][$i]." is to big. Max file size is ".$max_file_size."kb.
Your file(s) were not uploaded.
";
				
				// Check if the file already exists on the server..
			} Elseif(file_exists($folder.$file_name[$i])) {
				
				$error.= "The file: ".$_FILES['file']['name'][$i]." exists on this server, please rename your file.
Your file(s) were not uploaded.
";
				
			}
						
		} // If Files
	
	}
Come si può fare?

grazie ancora!!!
