php - FormData sends files but $_FILE is empty -


i have no idea why keep getting empty $_files global array when print out. ive been looking on can't see going wrong. because of have shown of code. if use button reaches server fine , works out. if use drag , drop no files on server? idea why? when print array array(0).

i found 1 problem while loop fixed still no files tho. incase people wondering if post action correct. url rewritten using mod_rewrite. displays correct php pages assuming the pages reached. mod_rewrite affect uploading of files. don't think so...?

here server file. doesn't matter incase

<?php  echo "server reached\n";   var_dump($_post);   var_dump($_files);   exit(); ?>

try without rewrite, issue.
