fopen(); "Remote host file access not accepted" on a local file?

I am using the Tcpdf module and PHP to create dymanic PDF invoices from an ordering system.

The script should then save the invoice into a folder called "invoices". The folder exists, and there are full permissions for "everyone" (Windows).

The code I am using is this:

$pdf->Output('invoices/Delivery Note.pdf', 'F');

This uses fopen to save the file.

However the error I am getting is: Warning: fopen(): remote host file access not supported, file://invoices/Delivery Note.pdf

This is a local file, not a remote one.

I attempted adding a / prefix like this:

$pdf->Output('/invoices/Delivery Note.pdf', 'F');

but then I get this error instead: Warning: fopen(file:///invoices/Delivery Note.pdf): failed to open stream: No such file or directory

I created the file, and left it empty, but the same error as above.

Does anyone know why I am getting this error?

you can use this script

'$'pdf->Output(dirname(FILE,2). '/invoices/Delivery Note.pdf', 'F');

In prestashop you can do it in this way $pdf->Output(_PS_ROOT_DIR_.'/modules/xxx/ticket.pdf', 'F');

I suggest using the following as Gerd has also suggested but make sure you use an absolute path:

$pdf->Output(__DIR__ . '/invoices/Delivery Note.pdf', 'F');

The path must be an absolute path & not a relative path. This PHP bug report explains why: https://bugs.php.net/bug.php?id=28820

The reason relative paths are not supported with the file:// wrapper comes down to a compromise in how UNC paths are dealt with (and more specifically how / are fuzzily interpreted as \ for windows installations).

For Example:

file://foo/bar

Could be interpreted as a relative URI: foo/bar from the current working directory, OR it could be interpreted as a UNC: \foo\bar (share bar on computer foo).

For this and a few internal reasons the file:// wrapper is limited to absolute paths when called explicitly. For relative paths either use realpath() {as you did in your report}, or omit the explicit naming of the file wrapper.

You can then avoid modifying the TCPDF code and worrying about any upgrades replacing your modified code.

similar to user1007017, but just comment the line like shown below (tcpdf 6.2.11)

public static function fopenLocal($filename, $mode) {
        if (strpos($filename, '://') === false) {
            //$filename = 'file://'.$filename;
        } elseif (stream_is_local($filename) !== true) {
            return false;
        }
        return fopen($filename, $mode);
    }

From php-Script you can use:

$pdf->Output(__DIR__ . '/invoices/Delivery Note.pdf', 'F');

After upgrading to the tcpdf 6.2.6 in vtiger 6.2 I've had the same problem, sending e-mail with pdf.

So I have changed the file:

 libraries/tcpdf/include/tcpdf_static.php

I have commented the code in fopenLocal() and changed the line 

 fopen($_SERVER['DOCUMENT_ROOT'].$filename, $mode);

see:

  /**
         * Wrapper to use fopen only with local files
         * @param filename (string) Name of the file to open
         * @param $mode (string) 
         * @return Returns a file pointer resource on success, or FALSE on error.  
         * @public static
         */
        public static function fopenLocal($filename, $mode) {
    //      if (strpos($filename, '://') === false) {
    //          $filename = 'file://'.$filename;
    //      } elseif (strpos($filename, 'file://') !== 0) {
    //          return false;
    //      }
            return fopen($_SERVER['DOCUMENT_ROOT'].$filename, $mode);
        }

After changing this, it worked.

I found the issue was that the path for fopen has to be from the document root, and not from the PHP script location.

C:\Website\www\script\invoice\invoice.pdf

For example if the PHP script is inside the "script" folder, and you want to create the pdf inside the "invoice" folder, the script needs to have "\script\invoice\invoice.pdf".

$pdf->Output($_SERVER['DOCUMENT_ROOT'].'/invoices/Delivery Note.pdf', 'F');
