PHP error: “A non-numeric value encountered”

  • Hi!

    When I click on generate “packing slip” on orders, I have PHP errors in my error.log like this:
    PHP message: PHP Warning: A non-numeric value encountered in /var/www/web/boutique/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/inline_renderer.cls.php on line 109
    PHP message: PHP Warning: A non-numeric value encountered in /var/www/web/boutique/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/inline_renderer.cls.php on line 109
    PHP message: PHP Warning: A non-numeric value encountered in /var/www/web/boutique/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/inline_renderer.cls.php on line 109
    …
    PHP message: PHP Warning: A non-numeric value encountered in /var/www/clients/web/boutique/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/style.cls.php on line 1280
    PHP message: PHP Warning: A non-numeric value encountered in /var/www/clients/web/boutique/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/lib/dompdf/include/style.cls.php on line 1280

    When there is too much loop error, I have a 502 error and it is impossible to generate the file.
    Can you help me?

    I edited the files concerned, add an intval(); and its seem to be OK.

    Thanks for reporting! I’m working on a new release (2.0) for this plugin which will incorporate the latest version of dompdf, which also has better PHP7.1 compatibility (which is what causes this warning). Since this will be released in a few weeks, I will not fix this in the current release.
