[wp-hackers] what is the best (fastest) way to check if a page has children?

[Viper007Bond]

Something along the lines of this will probably work:

if ( !empty( wp_list_pages( 'echo=0&child_of=' . $post->ID . 'title_li=' ) )
) $children = TRUE;


Similiar code in action: http://www.viper007bond.com/about/

It doesn't check for children as I manually assign the Page template, but it
still should give you some ideas.
