Bikin paging di wp?

Pagi agan2 mau tanya..
saya ingin membuat paging di website saya dengan menggunakan function berikut :
function pagenavi( $p = 2 ) { // pages will be show before and after current page
global $wp_query, $paged;
$max_page = $wp_query->max_num_pages;
if ( $max_page == 1 ) return; // don’t show when only one page
if ( empty( $paged ) ) $paged = 1;
echo ‘<span class=”pages”>Page : ‘ . $paged . ‘ of ‘ . $max_page . ‘ </span> ‘; // pages
if ( $paged > $p + 1 ) p_link( 1, ‘First’ );
if ( $paged > $p + 2 ) echo ‘<b>… </b> ‘;
for( $i = $paged – $p; $i <= $paged + $p; $i++ ) { // Middle pages
if ( $i > 0 && $i <= $max_page ) $i == $paged ? print “<span class=’page-numbers current’>{$i}</span> ” : p_link( $i );
}
if ( $paged < $max_page – $p – 1 ) echo ‘<b>… </b>’;
if ( $paged < $max_page – $p ) p_link( $max_page, ‘Last’ );
}
function p_link( $i, $title = ” ) {
if ( $title == ” ) $title = “Page {$i}”;
echo “{$i} “;
}

script ini berjalan jika url nya seperti ini : http://localhost/category/edisi.

nah permasalahannya jika url nya seperti ini : http://localhost/berita
pagingnya tak berfungsi atau jika saya klik hal 2 artikelnya tetap muncul spt di hal 1.
kira2 letak kesalahannya dimana ya gan?
