what do i do?

The upload path does not appear to be valid
That is the real problem. Make sure the /uploads/ directory exists, in the same directory of your index.php file.
PD: And use is_array() if you are passing data from unknown sources to foreach.

thanks, i tried again.i is sure the /uploads/ directory exists, if use of this is_array(), always have this message: The upload path does not appear to be valid.
What can I do?
[eluser]NeoArc[/eluser]
Try this (var_export() it first ):
$config['upload_path'] = FCPATH.'uploads'.DIRECTORY_SEPARATOR;
