PHP Make Directory -

i not sure why code breaking

mkdir("upload/".$username.'/'.$title.'/', 0700);       move_uploaded_file($_files["file"]["tmp_name"],       "upload/".$username.'/'.$title.'/' . $_files["file"]["name"]);       echo "stored in: " ."upload/".$username.'/'.$title.'/' . $_files["file"]["name"];       $link = "upload/".$username.'/'.$title.'/' . $_files["file"]["name"]; 

here errors

warning: mkdir() [function.mkdir]: no such file or directory in /volumes/shared/digital/_websites/_test/qpm/submit.php on line 101

i;m sure had working , have somehow broke it?

the echo stored in echos correct string not sure why mkdir failing, apologies if simple fix

there few things should know mkdir():

1. by default, can create directory if parent directory exists; can create intermediate directories if pass true third parameter.

2. without absolute path, it's hard directory created. can either use configuration file store or use combination of __file__, __dir__ , dirname() derive it.

i further advice never use value of $_files['file']['name'] directly create files on server; use tempnam(), optionally in combination sanitized version of original file name.
