Commas in Tag Cloud

Question

Using <?php wp_tag_cloud(''); ?> to display tags on my website, how do I separate each tag with a comma but also remove the comma from the last tag?

Answer 1

According to the Wordpress Codex on tag clouds, you need to specify a comma as the "separator" argument.

$args = "separator"=>",";
wp_tag_cloud($args);

Answer 2

 Filter the seperator arg for the tag cloud function. Put the following in your theme's functions.php

/**
 * Filter arguments of tag cloud widget to enlarge our text and
 * add commas
 */
function myfunc_filter_tag_cloud($args) {
    $args['smallest'] = 18;
    $args['largest'] = 32;
    $args['unit'] = 'px';
    $args['separator']= ', ';
    return $args;
}
add_filter ( 'widget_tag_cloud_args', 'myfunc_filter_tag_cloud');
