How do I display the degree of difficulty of a course?

The plugin comes with an helper function named dds_get_sensei_course_degree_of_difficulty().
It accepts a Sensei course ID or a WooCommerce product ID as first argument.

Choose where you would like to display degrees of difficulty and make use of that function in your theme’s functions.php file.
Here is a complete example to display the degree of difficulty next to the WooCommerce product price:

/**
 * WooCommerce template:
 * Add Sensei course degree(s) of difficulty
 *
 * @uses dds_get_sensei_course_degrees_of_difficulty()
 */
function mytheme_woocommerce_sensei_course_degrees_of_difficulty() {
    global $product;

    // Check product has a Sensei course.
    // Get Sensei course where WooCommerce product ID === course_woocommerce_product.
    $product_id = $product->get_id();

    if ( ! function_exists( 'dds_get_sensei_course_degrees_of_difficulty' ) ) {
        return;
    }

    $is_woocommerce_product = true;

    /**
     * Our course degrees of difficulty.
     *
     * @var array Array of arrays. Degree of difficulty array will provide id, name, slug & image_url.
     */
    $degrees_of_difficulty = dds_get_sensei_course_degrees_of_difficulty( $product_id, $is_woocommerce_product );

    if ( ! $degrees_of_difficulty ) {
        return;
    }

    foreach ( (array) $degrees_of_difficulty as $difficulty ) {

        $classes = 'mytheme-difficulty ' . $difficulty['slug'];

        $title = 'Degree of Difficulty: ' . $difficulty['name'];
        ?>
        <span class="mytheme-difficulty-wrapper">
            <span class="<?php esc_attr_e( $classes ); ?>" title="<?php esc_attr_e( $title ); ?>">
                <?php if ( $difficulty['image_url'] ) : ?>
                    <img src="<?php esc_attr_e( $difficulty['image_url'] ); ?>" alt="<?php esc_attr_e( $title ); ?>" />
                <?php else : ?>
                    <?php esc_html_e( $difficulty['name'] ); ?>
                <?php endif; ?>
            </span>
        </span>
        <?php
    }
}

/**
 * Add Sensei course degree(s) of difficulty after product price.
 *
 * woocommerce_template_single_price hook has priority 10
 */
add_action( 'woocommerce_single_product_summary', 'mytheme_woocommerce_sensei_course_degrees_of_difficulty', 15 );

/**
 * Add Sensei course degree(s) of difficulty after product price.
 *
 * woocommerce_template_loop_price hook has priority 10

add_action( 'woocommerce_after_shop_loop_item_title', 'mytheme_woocommerce_sensei_course_degrees_of_difficulty', 15 );
