I have a sidebar in wordpress registered like this:
register_sidebar( array(
'name' => 'Blog Sidebar',
'id' => 'blog_sidebar',
'before_widget' => '<div class="widget-wrapper col-xs-12 col-sm-6 col-md-6 col-lg-12">',
'after_widget' => '</div>',
'before_title' => '<h2 class="widget-title">',
'after_title' => '</h2>',
) );
Then, I'm dropping the tag cloud widget in there. It produces the widget code with title wrapped in <h2> and widget code wrapped in a <div> with classes above. So far, so good.
Now, I need to make some changes to how tag cloud is displayed, so I add a filter like so:
add_filter('widget_tag_cloud_args','set_tag_cloud_features');
function set_tag_cloud_features($args) {
$args = array(
'smallest' => 18,
'default' => 18,
'largest' => 18,
'unit' => 'px',
'show_count' => 1,
'format' => 'list',
'orderby' => 'count',
'order' => 'DESC'
);
return $args;
}
Somehow this messes up the widget HTML now. <h2> and the widget wrapper <div> are gone. Looking at the wp_tag_cloud function reference, I don't see how to pass any arguments to avoid this...
