Нужна помощь с кодом

Собственно сам код. Нужно сделать его менее объемным, более грамотным.

public function widget($args, $instance){
echo $args['before_widget'];
if (is_single()) {
    global $post;
    echo '<script type="text/javascript">
            function hide() {
            document.getElementById("dllist").style.visibility = "visible";
            }
            </script>';
    echo '<style>
    .dllist{
        display:none;
    }
    </style>';
    $link1 = get_field('dl1', $post->ID);
    $link2 = get_field('dl2', $post->ID);
    $link3 = get_field('dl3', $post->ID);
    $link4 = get_field('dl4', $post->ID);
    $link5 = get_field('dl5', $post->ID);
    $text1 = get_field('text1', $post->ID);
    $text2 = get_field('text2', $post->ID);
    $text3 = get_field('text3', $post->ID);
    $text4 = get_field('text4', $post->ID);
    $text5 = get_field('text5', $post->ID);
    if(is_user_logged_in()) {
        echo '<img src="/wp-content/uploads/2018/04/download.jpg" onclick="hide()" width="335px" height="120px">';
    }
            if($link5 && is_user_logged_in()) {
