Running PHP 7.0 on Ubuntu 16.04 and LibreOffice

New version of phpdocx 8.2 (Advanced) installed today.

phpdocx config file is modified to use libreoffice like so:

method = "libreoffice"

; libreoffice installation path, absolute path
path = "/usr/bin/soffice"

Creating docx files directly and from templates (with modifications) works perfectly.

When I try to convert any docx file to pdf I get errors. From the documentation and forums it looks like the recommended code is like this:

$docx = new TransformDocAdvLibreOffice();

$docx->transformDocument($docxname, $pdfname);

But that generates this error:

PHP Fatal error:  Uncaught Exception: The chosen extension is not supported 

I have no idea what that means. What extension isn't supported?

If I remove the phpdocx code and instead do it myself, this works perfectly:

exec("/usr/bin/soffice --headless --convert-to pdf:writer_pdf_Export --outdir $pdfname $docxname");

I thought it would be easier/safer/more reliable to use the docx-pdf conversion function in phpdocx, but I can't get it working. I even tried following the instructions in the website section called Debugging LibreOffice. That tells me to run a sample script called sample_1.php but that doesn't provide anything helpful. That script just generates a different error:

PHP Warning:  rename(./example_text.pdf,example_text.pdf): No such file or directory in /var/www/staging-wgaccounts/phpdocx/classes/TransformDocAdvLibreOffice.php on line 138

Any advice?

That exception:

PHP Fatal error:  Uncaught Exception: The chosen extension is not supported

appears when the file extension isn't one of the allowed extensions:

$this->_allowedExtensions = array('docx', 'pdf', 'odt', 'sxw', 'rtf', 'doc', 'txt', 'html', 'htm', 'wiki', 'png');

Maybe you are using uppercase file extensions?

To test the conversion plugin, please run the included sample in the examples/FormatConversion/transformDocument folder using PHP CLI mode.

If you send to contact[at] SSH access to your server and the path to phpdocx, the dev team will check it.

Thanks, I can't believe it was that obvious.

I had moved some file renaming code incorrectly. Now it works. Thank you.
