File Upload Applet / Discussion / Help: PHP Directory Structure Workaround

Brian - 2007-08-23

Hello all,
I'm fairly new to PHP, so there may, in fact, be a much better way of doing this, but it works for me rather well.

////file_upload.php source
<html>
<head>
<title>Uploader</title>
</head>

<body>
<applet name="JUpload" code="wjhk.jupload2.JUploadApplet" archive="wjhk.jupload.jar" width="700" height="500" mayscript>

<param name="lookandfeel" value="system">
<param name="nbFilesPerRequest" value="1">
<param name="postURL" value="upload.php">
Java 1.5 or higher plugin required.
</applet>
</body>
</html>

////upload.php source
//FORCE SOME PHP_INI SETTINGS
ini_set( "max_execution_time", 120 );
ini_set( "max_input_time", 240 );
ini_set( "upload_max_filesize", "50M" ); //Maximum allowed size for uploaded files.
ini_set( "post_max_size", "60M" ); //Maximum size of POST data that PHP will accept.
ini_set( "memory_limit", "70M" ); //Maximum amount of memory a script may consume

$save_path="files/";
array_walk($_FILES, 'moveFiles');

print_r($_FILES);
print_r($_POST);

//-----------------------------------------------------------------------------
// FUNCTIONS
//-----------------------------------------------------------------------------

function moveFiles($name, $key) {
global $save_path;
$id = $FILES[$key];
$tmpname = $_FILES[$key]['tmp_name'];
$filename = stripslashes($_FILES[$key]['name']);
$error = $_FILES[$key]['error'];
if ($error == UPLOAD_ERR_OK) {
$relpath = str_replace("\", "/", stripslashes($_POST["relpathinfo"][0]));
$filename = $relpath . "/" . $filename;
$filename = str_replace(" ", "", $filename);
echo $filename."\n";
$pos = strrpos($filename, "/");
if ($pos === false) {
$file = $filename;
$path = $save_path;
} else {
$file = substr($filename, $pos);
$dir = substr($filename, 0, $pos);
$path = $save_path . "/" . $dir;
}

if (@move_uploaded_file($tmpname, $path . "/" . $file)) { echo "SUCCESS\n"; } else { mkdir_recursive($path); move_uploaded_file($tmpname, $path . "/" . $file); echo "SUCCESS AFTER MAKING DIR\n"; } }

}

// Creates the directories if needed.
function mkdir_recursive($dir){

do {
$tempdir = $dir;
while (!is_dir($tempdir)) {
$basedir = dirname($tempdir);

if ($basedir == '/' || is_dir($basedir)) { mkdir($tempdir,0777); } else { $tempdir=$basedir; } }

} while ($tempdir != $dir);
}

This works by pulling the "relpathinfo" $_POST information for each file, and prepending it to the filename sent through the $_FILES array. Note that you need to have the nbFilesPerRequest set to 1 in the applet page, or else you'll end up with files all over the place, as I've not made the relpathinfo variable 'dynamic'. This is a quick and dirty fix, and I hope to get it working with the file chunks, but so far no luck with that.

Any help or comments would be greatly appreciated!

  Great!
  
  Thanks for your contribution.
  
  We'll try to embed it in the package, or at least add a link to this thread in the doc of the next release.
  (added on my todo list)

  Hi,
  I'm sorry but it's not working to me - JUpload is simply not sending "relpathinfo" in the POST request (even if I got nbFilesPerRequest=1). What version are you using? I got 3.0.1.
  
  My "debug output" of send parameters by JUpload
  
  _FILES: File0 => Array
  name => yellow.gif
  type => image/gif
  tmp_name => /tmp/phpfe3iGG
  error => 0
  size => 1096
  _POST: mimetype => image/gif
  _POST: md5sum => 2caaa7e071620c5b686d8550335612e2
  
  I also "grepped" the JUpload source files (3.0.1) for the "relpath" string and no match :-(
  
  Thanks for any help,
  Libor

    I'm using 3.1.0b1 [SVN-Rev: 309]
    
    I was having alot of problems with it at first, until I deleted the "temporary files" in the Java control panel. Even though my site was referencing the proper version of the uploader, Java had cached another version, and would pull that up instead.

      Hi,
      can you please send me "compiled" version of it? I'm not Java developer and if I don't have to learn, how to compile Java on MacOS, I'd be very happy :-) My email is: libor.vanek [at] gmail.com
      
      Thx,
      Libor

        Hi,
        
        The compiled version of the applet is available in each package available on sourceforge. Open the release jar file, and the /wwwroot/wjhk.jupload.jar file. It's the compiled applet.
        
        You can also browse SVN, and get the up to date applet (same path).
