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

WP Query by 4 different taxonomies

I need to make a shortcode that uses the values of four different taxonomies. I am trying to modify code that I have used to query attachments (in media) based off of multiple taxonomy terms, but what I need is to wp_query based off of 4 (four) taxonomies values. I realize that I am way off, but perhaps somebody can help put me on the right track.
