Fatal error on PHP 8+ “Unsupported operand types: int + string”

    Hi,

    I’m getting a fatal error on my site (hosted on Cloudways) coming from this plugin:

    PHP Fatal error: Uncaught TypeError: Unsupported operand types: int + string in
/wp-content/plugins/woo-ultimate-order-combination/inc/functions.php:666

    This looks like a PHP 8+ compatibility issue: the code at line 666 is adding an integer and a string with the + operator, and one of the values is apparently not numeric (e.g. an empty string or null). On PHP 7.x this would just throw a warning and treat the string as 0, but on PHP 8+ it’s a fatal TypeError.

    Could you take a look at line 666 of inc/functions.php and add a proper type cast ((int)/(float)) or an is_numeric() check before the addition?

    Environment:

    • WordPress + WooCommerce (Cloudways hosting)
    • PHP version: 8.3
    • Plugin version: 2.0.6

    Happy to provide more details (full stack trace, steps to reproduce) if needed.

    Thanks!

    Hi,

    Thank you for reporting this and for providing the details. I’ve identified the PHP 8+ compatibility issue and fixed it by properly handling the tax values as numeric amounts.

    I’m releasing a new version of the plugin with this fix included. Please update to the latest version and let me know if you encounter any further issues.

    Thanks again for reporting it!
