FPDF error: Unable to create output file

I am facing this strange problem with PHP upload script. Hoping to get some help from someone please.

Below is the details of this problem:

DOCUMENT_ROOT is "/var/www/html"

PHP upload works fine to a folder called "/var/www/html/uploads"

Have Another directory hosting different webpage at "/var/www/html/folder" Same PHP upload.sh script can not upload files to "/var/www/html/directory/folder" directory.

Folder permission has been set to 0777 to both "/var/www/html/directory/folder" and "/var/www/html/uploads" Same upload script is used in both folders.

Below value is set in upload.php located in both folders.

$uploads = $_SERVER['DOCUMENT_ROOT'] . "folder/uploads/files/"

I have tried setting absolute path in $uploads as follows but did not work:

$upload_dir = "/var/www/html/files/"

Upload is failing with below error:

Message: fopen(var/www/html/folder/uploads/files/filename.pdf): failed to open stream: No such file or directory
FPDF error: Unable to create output file:(/var/www/html/folder/uploads/files/filename.pdf)

Any idea why the server is not letting upload.php from "/var/www/html/folder" to write to "/var/www/html/folder/uploads/" directory.

No related message could be found in any log files.

=============================================================

It appreas that PHP is not able to mkdir in /var/www/html/folder/uploads/files/.

Piece of code that creates the directory is:

  $uploadPath = "folder/uploads/files/";
  $dir = $_SERVER['DOCUMENT_ROOT'] . $uploadPath;

    if (!is_dir($dir)) @mkdir($dir, 0777);
    return $uploadPath;

Any idea why it is unsable to to do so with the above mkdir code?

Thank you.

It probably is but you are trying to write/open a different folder i.e./var/www/html/folder/uploads/ --- var/www/html/folder/uploads/files/ - user2417483
Hi Jeff, Thank you for the reply. It is a subdirectory and have given 777 permission for it too. I just can't understand why it can not create file within /var/www/html/folder/uploads/. - BBT

make sure that file /var/www/html/folder/uploads/files/filename.pdf is not open anywhere when you run script. if it's open somewhere else then TCPDF can't open it.

For those who are facing similar problems, my issue was resolved after adding recursive flag. My mkdir command was changed as follows:

From:

if (!is_dir($dir)) @mkdir($dir, 0777);

To:

if (!is_dir($dir)) @mkdir($dir, 0777, true);
