I am using the following code:

require_once 'classes/';

$sign = new SignDocx();

$sign->setPrivateKey('Test.pem', 'mypass');

$sign->setSignatureComments('This document has been signed by me');


I can not sign the docx document. The following message appears:

sort() expects parameter 1 to be array, null given in [.../vendor/phpdocx/phpdocx/Classes/Phpdocx/Sign/ 462]

Does anyone know what this error can be?

It seems the DOCX doesn't contain a valid .rels file, or PHP is unable of read it.

Please run the included sample DigitalSignature\signDocx\sample_1.php using PHP CLI mode and reply the topic if it works or not (note that signdocx overwrites the DOCX to be signed to add the signature).

If the included sample works, please send to contact[at] the DOCX you are trying to sign and the dev team we'll check it.

Which version of PHP are you using? The digital signature module is fully tested with PHP 5.2 to PHP 7.

I run the file Digital Signature\signDocx\sample1.php and it worked. Php is version 7.

Does not work when I generate the docx file ($phpWord->createDocx ($ path)). Any idea?

Please do these tests:

· Generate the most simple DOCX, a single text, and then sign it (all in the same script).

· Use a standalone script to sign your DOCX (just to test it standalone). Maybe the DOCX file is not correctly closed by PHP when createDocx is called and then sign docx try to open it in the same script?

If the second test doesn't work, please send to contact[at] the DOCX you are trying to sign and the dev team we'll check it.

Now it's working.

I change code block below:

new \Phpdocx\Create\CreateDocx();


new \Phpdocx\Create\CreateDocxFromTemplate($blank_template_path);


Thank you for your help
