[Null]

Ok I have written a function to get the tags in a row, but I want to have them comma seperated, any ideas?

function bb_row_tags( $args = null ) {

$defaults = array(

'tags' => false,

'format' => 'row',

'topic' => 0,

);



$args = wp_parse_args( $args, $defaults );

extract( $args, EXTR_SKIP );



if ( !$topic = get_topic( get_topic_id( $topic ) ) ) {

return false;

}



if ( !is_array( $tags ) ) {

$tags = bb_get_topic_tags( $topic->topic_id );

}



if ( !$tags ) {

return false;

}



$r = '';

switch ( strtolower( $format ) ) {

case 'row' :

default :

$args['format'] = 'row';

foreach ( $tags as $tag ) {

$r .= _bb_row_tag_item( $tag, $args );

}

break;

}

echo $r;

}



function _bb_row_tag_item( $tag, $args ) {

$url = esc_url( bb_get_tag_link( $tag ) );

$name = esc_html( bb_get_tag_name( $tag ) );

if ( 'row' == $args['format'] ) {

$id = 'tag-' . $tag->tag_id . '_' . $tag->user_id;

return "t" . '<a href="' . $url . '" rel="tag">' . $name . '</a>' . "n";

}

}
