Woocommerce - Display Lowest Price on Category (Archive) Page Only - php

Question

I'm trying to display the lowest price instead of the price range on the category pages while continuing to display the price range on the individual product pages.
I found this answer from someone else's question:
add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);
function custom_variation_price( $price, $product ) {
$price = '';
if ( !$product->min_variation_price || $product->min_variation_price !== $product->max_variation_price ) {
$price .= '<span class="from">' . _x('From', 'min_price', 'woocommerce') . ' </span>';
$price .= woocommerce_price($product->get_price());
}
return $price;
}
And it works, but when I put the code in functions.php, it applies to the whole site. I only want it to apply to the category pages.
Also, when I use this code, items with only one price end up with no price being displayed.
What can I do?
Here's a screenshot of what I mean:

If I got you right then you just need to display the minimal price whenever there's a range of prices. So basically you need to change the $price's HTML only if product's minimal price is set (if it's not set then the product has a single price and no change is needed). I also included the check for whether it's a category page. Here's the code:
add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);
function custom_variation_price( $price, $product ) {
if ( ! empty($product->min_variation_price) && is_product_category() ) {
$price = '<span class="from">' . _x('From', 'min_price', 'woocommerce') . ' </span>';
$price .= woocommerce_price($product->get_price());
}
return $price;
}
