Php Variable not working in UPLOAD script -

-

i have following script:

<?php  $userid = $_get['user'];  // list of permitted file extensions $allowed = array('png', 'jpg', 'gif','zip');  if(isset($_files['upl']) && $_files['upl']['error'] == 0){      $extension = pathinfo($_files['upl']['name'], pathinfo_extension);      if(!in_array(strtolower($extension), $allowed)){         echo '{"status":"error"}';         exit;     }       if(move_uploaded_file($_files['upl']['tmp_name'], '../../'.$userid.'/assets/'.$_files['upl']['name'])){           echo '{"status":"success"}';         echo ' '.$userid;         exit;     } }  echo '{"status":"error"}'; echo ' '.$userid; exit;  ?>

the problem in line:

    if(move_uploaded_file($_files['upl']['tmp_name'], '../../'.$userid.'/assets/'.$_files['upl']['name'])){

when use path - works fine , upload successful:

'../../assets/'.$_files['upl']['name']

or

'../assets/'.$_files['upl']['name']

or

'assets/'.$_files['upl']['name']

all of these 3 work fine - when add variable (from url path), not work? know variable "userid" being recognized because echoing out before , after path , displays on screen. did set write permissions on of folders, defined variable.

any thoughts?

this added >>>>>> first file....

<?  $userid = $_get['user'];  ?>  <!doctype html> <html>      <head>         <meta charset="utf-8"/>         <title>mini ajax file upload form</title>          <!-- google web fonts -->         <link href="http://fonts.googleapis.com/css?family=pt+sans+narrow:400,700" rel='stylesheet' />          <!-- main css file -->         <link href="css/style.css" rel="stylesheet" />     </head>      <body>     <p style="text-align:center"><? echo $userid; ?></p>          <form id="upload" method="post" action="upload.php" enctype="multipart/form-data">             <div id="drop">                 drop here                  <a>browse</a>                 <input type="file" name="upl" multiple />             </div>              <ul>                 <!-- file uploads shown here -->             </ul>          </form>           <!-- javascript includes -->         <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>         <script src="js/jquery.knob.js"></script>          <!-- jquery file upload dependencies -->         <script src="js/jquery.ui.widget.js"></script>         <script src="js/jquery.iframe-transport.js"></script>         <script src="js/jquery.fileupload.js"></script>          <!-- our main js file -->         <script src="js/script.js"></script>       </body> </html>

this processing file....

<?php  $userid = $_get['user'];  // list of permitted file extensions $allowed = array('png', 'jpg', 'gif','zip');  if(isset($_files['upl']) && $_files['upl']['error'] == 0){      $extension = pathinfo($_files['upl']['name'], pathinfo_extension);      if(!in_array(strtolower($extension), $allowed)){         echo '{"status":"error"}';         exit;     }      // if(move_uploaded_file($_files['upl']['tmp_name'], '../../'.$userid.'/assets/'.$_files['upl']['name'])){       if(move_uploaded_file($_files['upl']['tmp_name'], '../../'.$userid.'/assets/'.$_files['upl']['name'])){           echo '{"status":"success"}';         echo ' '.$userid;         exit;     } }  echo '{"status":"error"}'; echo ' '.$userid; exit;  ?>

unless you're creating subdirectory in ../../ each , every user manually, need create directory user before trying move files it.

if(!file_exist("../../$userid/")     mkdir("../../$userid/");

... , can move file it.
