I am developing a wordpress theme for themeforest so its for commercial use and adding a custom input field of social media to the user menu in the WordPress dashboard gives error after i click Update Profile. The front-end appears correctly but when i submit it by clicking Update Profile button it takes me to a next page where it says

How do I make my terms for each product display via foreach loop? (woocommerce)

This is my current loop to display my products via woocommerce. When I do print_r($category_array); It returns the array, but when I try to use a function to call it so I can do what I want to with the data, it makes and my entire screen doesn’t display after the loop. Maybe it’s a mistake in my function? Still very new to woocommerce and wp_loops. Thank you
