note 91787 rejected from function.unlink by thiago

Note Submitter: markandrewperry at hotmail dot co dot uk ---- I am having trouble using the unlink() function. I have a file name posted from a form, i get this filename and then need to delete the file but the unlink function isn't working correctly, the code is below. <?php $fullname = $_POST['fullname']; chdir('../portfolio_full'); unlink($fullname); ?> The filename is held in $fullname and this is what i need to delete, but it only seems to work when i hard code the file name e.g. <?php unlink('image.jpg'); ?> does anybody know why this would happen?I have tried setting file and directory permissions and changing the working directory but none of them worked. any help is greatly appreciated :)
