See Details Button instead of “Add to Cart”

Hi @trixox – this code should do that on the shop or category pages for you:

/* Remove add to cart button */
add_action('woocommerce_before_shop_loop_item','remove_loop_add_to_cart_button'); 
function remove_loop_add_to_cart_button(){
    global $product; // Current product
    remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart', 10 ); 
}
/* Add see details button to replace add to cart button*/
add_action('woocommerce_after_shop_loop_item','replace_add_to_cart_with_view_product'); 
function replace_add_to_cart_with_view_product() {
    global $product;
    $link = get_permalink(); 
    echo '<a class="button" href="' . esc_attr($link) . '">See Details</a>';
}

As far as replacing the button for the pages generated using WooCommerce Blocks, I’m afraid that is not currently customizable (more on that here).
