Add a Class to Current Page WP_LINK_PAGES

1 comment

1. This is what I use as a replacement for wp_link_pages(). Instead of a separate class it uses another element for the current page, because a page should never link to the current URL.

   /**
    * Modification of wp_link_pages() with an extra element to highlight the current page.
    *
    * @param  array $args
    * @return void
    */
   function t5_numerical_link_pages( $args = array () )
   {
       $defaults = array(
           'before'      => '<p>' . __( 'Pages:', 't5_theme' )
       ,   'after'       => '</p>'
       ,   'link_before' => ''
       ,   'link_after'  => ''
       ,   'pagelink'    => '%'
       ,   'echo'        => 1
       // element for the current page
       ,   'highlight'   => 'b'
       );
   
       $r = wp_parse_args( $args, $defaults );
       $r = apply_filters( 'wp_link_pages_args', $r );
       extract( $r, EXTR_SKIP );
   
       global $page, $numpages, $multipage, $more, $pagenow;
   
       if ( ! $multipage )
       {
           return;
       }
   
       $output = $before;
   
       for ( $i = 1; $i < ( $numpages + 1 ); $i++ )
       {
           $j       = str_replace( '%', $i, $pagelink );
           $output .= ' ';
   
           if ( $i != $page || ( ! $more && 1 == $page ) )
           {
               $output .= _wp_link_page( $i ) . "{$link_before}{$j}{$link_after}</a>";
           }
           else
           {   // highlight the current page
               // not sure if we need $link_before and $link_after
               $output .= "<$highlight>{$link_before}{$j}{$link_after}</$highlight>";
           }
       }
   
       $echo and print $output . $after;
       return $output . $after;
   }
