Is it possible to include a "Read more" function with this code

Hi there,

Not quite sure if I understand.

Where are trying to add read more?

https://area51.lydsenteret.no/produktkategori/bil/bilstereo/

At the end of the excerpt where there is now ...
Or the whole Excerpt as a link to the product itself.

Give this a shot:

add_action( 'woocommerce_after_shop_loop_item', 'diggs_custom_shop_item', 5);
function diggs_custom_shop_item() {
	global $post;
		/* product excerpt  */
	if ( $post->post_excerpt ) {
		echo '<div class="diggs-shop-excerpt">' . apply_filters( 'woocommerce_short_description', wp_html_excerpt($post->post_excerpt,100,'... ') ) . '</div>';

                echo '<p><a href="' . get_permalink( $post->ID ) . '" class="button">Read more</a></p>';
	}
}

Let me know :)

Thanks Tom, I rebuilt it a bit ;-)

add_action( 'woocommerce_after_shop_loop_item', 'diggs_custom_shop_item', 5);
function diggs_custom_shop_item() {
	global $post;
		/* product excerpt  */
	if ( $post->post_excerpt ) {
		echo '<div class="diggs-shop-excerpt">' . apply_filters( 'woocommerce_short_description', wp_html_excerpt($post->post_excerpt,80,'<a href="' . get_permalink( $post->ID ) . '"><strong>...Les mer</strong></a>') ) . '</div>';
	}
}

Perfect :) Thanks for sharing!
