Can't display all custom taxonomy values - wordpress

Question

This is my code to display all taxonomy values. It works but shows only first value and twice. How to stop duplicate this value?
// Register Custom Taxonomy-poleca
function recommend_custom_taxonomy_Item() {
$labels = array(
'name' => 'Poleca',
'singular_name' => 'Poleca',
'menu_name' => 'Poleca',
'all_items' => 'Wszyscy polecający',
'parent_item' => 'Parent Brand',
'parent_item_colon' => 'Parent Brand:',
'new_item_name' => 'Nowy Polecający',
'add_new_item' => 'Dodaj nowego polecającego',
'edit_item' => 'Edytuj polecającą',
'update_item' => 'Update polecający',
'separate_items_with_commas' => 'Oddziel przecinkami',
'search_items' => 'Szukaj recommend',
'add_or_remove_items' => 'Add or remove polecającego',
'choose_from_most_used' => 'Choose from the most used Brands',
);
$args = array(
'labels' => $labels,
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'show_in_nav_menus' => true,
'show_tagcloud' => true,
);
register_taxonomy( 'recommend', 'product', $args );
}
add_action( 'init', 'recommend_custom_taxonomy_item');
add_action( 'woocommerce_before_add_to_cart_button', 'add_recommend_term');
function add_recommend_term() {
$terms = get_the_terms(get_the_ID(), 'recommend');
$author_image = wp_get_attachment_image_src($img_id );
foreach ( $terms as $term ) {
if (!is_wp_error($terms) && !empty($terms)) { ?>
<div class="recommend-name"><?php echo esc_html($terms[0]->name); ?> <br><?php echo esc_html($terms[0]->description);?></div>
<?php }
}

Just replace your above code's parts with follows snippet -
add_action( 'woocommerce_before_add_to_cart_button', 'add_recommend_term');
function add_recommend_term() {
$terms = get_the_terms( get_the_ID(), 'recommend' );
if ( $terms && ! is_wp_error( $terms ) ) :
foreach ( $terms as $term ) {
?>
<div class="recommend-name">
<a href="<?php echo esc_url( get_term_link( $term ) ); ?>">
<?php echo esc_html( $term->name ); ?><br><?php echo esc_html( $term->description ); ?>
</a>
</div>
<?php }
endif;
}
