[wp-hackers] Re: How to redirect to login when filtered posts are empty?

[DD32]

We might be on completely different pages, but heres some code from my  
latest plugin:

add_action('template_redirect','dda_template');
function dda_template($arg){
	global $wp_query;
	if( isset($wp_query->query_vars['ddeviantart']) )
		add_filter('home_template','dda_template_override');
	return $arg;
}
function dda_template_override($template){
	//Override the template for the current page and replace it with our own.
	return dirname(__FILE__).'/dda_portfolio.php';
}


ie. Conditionally add the 2nd filter only if its needed..
