note 91787 added to function.unlink

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 :) ---- Server IP: 209.41.74.194 Probable Submitter: 81.149.229.61 ---- Manual Page -- http://www.php.net/manual/en/function.unlink.php Edit -- https://master.php.net/note/edit/91787 Del: integrated -- https://master.php.net/note/delete/91787/integrated Del: useless -- https://master.php.net/note/delete/91787/useless Del: bad code -- https://master.php.net/note/delete/91787/bad+code Del: spam -- https://master.php.net/note/delete/91787/spam Del: non-english -- https://master.php.net/note/delete/91787/non-english Del: in docs -- https://master.php.net/note/delete/91787/in+docs Del: other reasons-- https://master.php.net/note/delete/91787 Reject -- https://master.php.net/note/reject/91787 Search -- https://master.php.net/manage/user-notes.php
