PHP POST method upload -

-

i'm having trouble debugging why processing of file upload not working. i've created html5 file uploader on page calls upload.php.

upload.php 

// file should saved in same folder upload.php $uploaddir = '/';  $uploadfile = $uploaddir . basename($_files['filetoupload']['name']);   echo '<pre>'; if (move_uploaded_file($_files['filetoupload']['tmp_name'], $uploadfile)) {     echo "file valid, , uploaded.\n"; } else {     echo "possible file upload attack!\n"; }  echo 'here more debugging info:';  print_r($_files);  print "</pre>";

the result of debug shows me following:

enter image description here

move_uploaded_file appears return false , not being able move uploaded file temp location specified location.

i've made sure set permissions on folder upload.php resides , file should save 777.

question there way more information why file not saved me understand did wrong ?

// file should saved in same folder upload.php $uploaddir = '/';

/something absolute path; $uploaddir points root of file system (that's not same document_root of webserver). webserver process doesn't have write permissions there.

take @ __dir__ "constant" @ http://php.net/language.constants.predefined
