    Hi, trying to limit tag count to 5. With no limit,

    this works:

    function pastLectures() {
    $args = array('order' => 'DESC');
    $posttags = get_tags($args);
    $tags = '';
    $tags .= '<ul>';
    if ($posttags) {
        foreach($posttags as $tag) {
            $tempYear = substr($tag->slug, 0, 4);
            $pastLecturesYes = get_field('add-to-past-lecture-series', 'post_tag_'.$tag->term_id);
            if ($pastLecturesYes[0] == 'add') {
                $tagLink = get_tag_link($tag->term_id);
                $tags .= '<li><a href="'.$tagLink.'"> '.$tag->name.'</a></li>';
            }
        }
    }
    $tags .= '</ul>';
    return $tags;
}

    trying to limit count to 5 isn’t working, what am I doing wrong?

    
function pastLectures() {
    $args = array('order' => 'DESC');
    $posttags = get_tags($args);
    $count = 0;
    $tags = '';
    $tags .= '<ul>';
    if ($posttags) {
        foreach($posttags as $tag) {
            $count++;
            $tempYear = substr($tag->slug, 0, 4);
            $pastLecturesYes = get_field('add-to-past-lecture-series', 'post_tag_'.$tag->term_id);
            if ($pastLecturesYes[0] == 'add') {
                $tagLink = get_tag_link($tag->term_id);
                $tags .= '<li><a href="'.$tagLink.'"> '.$tag->name.'</a></li>';
            }
            if( $count >5 ) break;
        }
    }
    $tags .= '</ul>';
    return $tags;
}

    I;m not sure if this is what you are trying to accomplish https://www.wpbeginner.com/wp-themes/how-to-show-limited-number-of-tags-after-posts-in-your-wordpress-theme/

    Trying to just limit the count to 5 on the working chunk of code. Thinking I am just missing something simple here.

    Never mind, just had the count and count++ mixed up here is the working code.

    function pastLectures() {
    $args = array('order' => 'DESC');
    $posttags = get_tags($args);
    $count = 0;
    $tags = '';
    $tags .= '<ul>';
    if ($posttags) {
        foreach($posttags as $tag) {
            //print_r($tag);
            $tempYear = substr($tag->slug, 0, 4);
            $pastLecturesYes = get_field('add-to-past-lecture-series', 'post_tag_'.$tag->term_id);
            if ($pastLecturesYes[0] == 'add') {
                $count++;
                $tagLink = get_tag_link($tag->term_id);
                $tags .= '<li><a href="'.$tagLink.'"> '.$tag->name.'</a></li>';
                if( $count > 4 ) break;
            }

        }
    }
    $tags .= '</ul>';
    return $tags;
}
