WordPress主题中添加文章列表页页码导航的PHP代码实例，_PHP教程

WordPress主题中添加文章列表页页码导航的PHP代码实例，

WordPress 默认给主题开发者的建议是在文章列表底部提供上下页按钮，所以没有提供直接用在文章列表下的分页导航的函数。这里我提供一个比较完善的分页导航函数。

/**
  *WordPress 文章列表分页导航

*/
function Bing_get_pagenavi( $query = false, $num = false, $before = '
', $after = '
', $options = array() ){
  global $wp_query;
  $options = wp_parse_args( $options, array(
    'pages_text' => '%CURRENT_PAGE%/%TOTAL_PAGES%',
    'current_text' => '%PAGE_NUMBER%',
    'page_text' => '%PAGE_NUMBER%',
    'first_text' => __( '« 首页', 'Bing' ),
    'last_text' => __( '尾页 »', 'Bing' ),
    'next_text' => __( '»', 'Bing' ),
    'prev_text' => '«',
    'dotright_text' => '...',
    'dotleft_text' => '...',
    'num_pages' => 5,
    'always_show' => 0,
    'num_larger_page_numbers' => 3,
    'larger_page_numbers_multiple' => 10
  ) );
  if( $wp_query->max_num_pages request;
    $numposts = $query->found_posts;
    $max_page = $query->max_num_pages;
    $posts_per_page = intval( $num );
  }else{
    $request = $wp_query->request;
    $numposts = $wp_query->found_posts;
    $max_page = $wp_query->max_num_pages;
    $posts_per_page = intval( get_query_var( 'posts_per_page' ) );
  }
  $paged = intval( get_query_var( 'paged' ) );
  if( empty( $paged ) || $paged == 0 ) $paged = 1;
  $pages_to_show = intval( $options['num_pages'] );
  $larger_page_to_show = intval( $options['num_larger_page_numbers'] );
  $larger_page_multiple = intval( $options['larger_page_numbers_multiple'] );
  $pages_to_show_minus_1 = $pages_to_show - 1;
  $half_page_start = floor( $pages_to_show_minus_1 / 2 );
  $half_page_end = ceil( $pages_to_show_minus_1 / 2 );
  $start_page = $paged - $half_page_start;
  if( $start_page  $max_page ){
    $start_page = $max_page - $pages_to_show_minus_1;
    $end_page = $max_page;
  }
  if( $start_page  $max_page ) $larger_start_page_end = $max_page;
  if( $larger_end_page_end > $max_page ) $larger_end_page_end = $max_page;
  if( $max_page > 1 || intval( $options['always_show'] ) == 1 ){
    $pages_text = str_replace( '%CURRENT_PAGE%', number_format_i18n( $paged ), $options['pages_text'] );
    $pages_text = str_replace( '%TOTAL_PAGES%', number_format_i18n( $max_page ), $pages_text);
    echo $before;
    if( !empty( $pages_text ) ) echo '' . $pages_text . '';
    if( $start_page >= 2 && $pages_to_show ' . $first_page_text . '';
    }
    if( $larger_page_to_show > 0 && $larger_start_page_start > 0 && $larger_start_page_end ' . $page_text . '';
      }
    }
    previous_posts_link( $options['prev_text'] );
    for( $i = $start_page;$i ' . $current_page_text . '
