PHP code example for adding page number navigation to the article list page in WordPress theme,

WordPress’s default suggestion to theme developers is to provide up and down page buttons at the bottom of the article list, so it is not provided Function used directly in paging navigation under the article list. Here I provide a relatively complete paging navigation function.

  }
  echo $after;
}

Then add the following code where you need to use paging navigation:

<&#63;php if( function_exists( 'Bing_get_pagenavi' ) ) Bing_get_pagenavi(); &#63;>
