Bug Report – Issues Found in MarketKing with PHP 8.2

Hi,

I would like to report two issues that I have encountered while using MarketKing in a WordPress + WooCommerce environment. These issues appear to be directly related to the plugin’s code and its compatibility with PHP 8.2.

1) Deprecated Warning – Function Parameter Order

Error message:

Deprecated: Optional parameter $order declared before required parameter $currency is implicitly treated as a required parameter in /home/USERNAME/public_html/wp-content/plugins/marketking-pro/includes/stripe/class-marketking-stripe-helper.php on line 42

File & line: /marketking-pro/includes/stripe/class-marketking-stripe-helper.php → line 42

Analysis: The function defines an optional parameter ($order) before a required parameter ($currency). Since PHP 8.0, this parameter declaration order raises a deprecation notice. This may lead to compatibility issues in future PHP versions if not adjusted.

2) Undefined Variable $stores_slug

Error message:

Warning: Undefined variable $stores_slug in /home/USERNAME/public_html/wp-content/plugins/marketking-multivendor-marketplace-for-woocommerce/includes/class-marketking-core.php on line [exact line may vary, but warning is triggered during execution]

File & location: /marketking-multivendor-marketplace-for-woocommerce/includes/class-marketking-core.php

→ line 452 and 458

Analysis: The variable $stores_slug is being used without being initialized beforehand. This results in a PHP warning and may affect URL generation or slug handling for vendor stores. Proper initialization or a conditional check for this variable would prevent the warning.

Summary

Both of these issues reduce stability and forward compatibility of the plugin under PHP 8.2. I kindly request that these be addressed in the next MarketKing release to ensure smooth operation in modern hosting environments.

Please confirm whether these bugs are scheduled for fixing in the upcoming update.

Best regards,
