    Hi,

    thanks for the excellent plugin, it just does what it is supposed to do. 🙂

    I am just looking at the source code and try to extend the plugin so I can limit the random post to a dynamically set category. I saw

    function rpl_change_ptype( $args ) {
  $args['category_name'] = 'your_category_name_goes_here';

  return $args;
}
add_filter( 'random_post_args', 'rpl_change_ptype' );

    What i want is to set the category dynamically within my template. Basically I want to call random post link with a category slug
    <?php random_post_link('Feeling lucky','your_category_name_goes_here'); ?>
    Should be not difficult to do I assume but I am new to wordpress development …

    Thanks buddies

    martin

    Okay here is what i came up with quickly ….

    firstly I just add the category as optional parameter to random_post_link, add it to the query string

    function random_post_link($text = 'Random Post',$catcat = '') {
	printf('<a href="%s">%s</a>', get_random_post_url($catcat), $text);
}

function get_random_post_url($catcat) {
	$cat = empty($catcat) ? '' : '=' . $catcat;
	return trailingslashit(get_bloginfo('url')) . '?' . Random_Post_Link::query_var .  $cat;
}

    and use this information 

    $cat_name = $_GET[self::query_var];
if (!empty($cat_name)) {
                        $args = array_merge($args, array(
			'category_name' => $cat_name,
		));
}

    of course this could be improved on but for now it works for me …
