The WP CLI never ceases to impress me. You can do lots of things with just a few lines of code.
In this code snippet, I let the WP CLI create 15 products with random images from Lorem Picsum, prices are also random within the 1-1000 range.
The reason I use Lorem Picsum specifically is that it provides URLs with extension compatible with the WordPress media upload condition, other services don’t have this.
The code
counter=1
until [ $counter -gt 15 ]
do
product_id=$(wp post generate --post_type=product --count=1 --post_title="Product ${counter}" --format=ids)
random_price=$(shuf -i 1-100 -n 1)
wp media import 'https://picsum.photos/600/400.jpg' --post_id=$product_id --title="Image for Product ${counter}" --featured_image
wp post meta set $product_id _price $random_price
counter=$(($counter + 1))
done
