ok, thanks I got the idea, though imho it could be better to add some action assigning $post to some other global variable instead of modifying template files

Yeah, l did it 🙂

add_filter('the_posts','tester_addposts');
class tester_ad
{
	public $ID="0";
	public $post_content="AD";
	public $post_title="AD";
}

function tester_addposts($posts)
{
	$adunit=new tester_ad();
	$adunit=array($adunit);
	return array_merge($adunit,array($posts[0]),$adunit,array_slice($posts,1));
}

Thanks.

Otto42, thanks! Hovewer in this case TEMPLATEPATH won’t work, probably because this constant is redefined after the theme is changed and switch_theme is executed before, so it returns the path to current template, but get_template_directory() returns the new path to template and that’s cool:) Thanks once again)
