### Function: Round To The Nearest Value
function tie_n_round($num, $tonearest) {
return floor($num/$tonearest)*$tonearest;
}
### Function: Page Navigation Options
function tie_pagenavi_init() {
$pagenavi_options = array();
$pagenavi_options['pages_text'] = __('Page %CURRENT_PAGE% of %TOTAL_PAGES%' );
$pagenavi_options['current_text'] = '%PAGE_NUMBER%';
$pagenavi_options['page_text'] = '%PAGE_NUMBER%';
$pagenavi_options['first_text'] = __('« First');
$pagenavi_options['last_text'] = __('Last »');
$pagenavi_options['next_text'] = __('»','tie');
$pagenavi_options['prev_text'] = __('<<','tie');
$pagenavi_options['dotright_text'] = '...';
$pagenavi_options['dotleft_text'] = '...';
$pagenavi_options['num_pages'] = 5;
$pagenavi_options['always_show'] = 0;
$pagenavi_options['num_larger_page_numbers'] = 3;
$pagenavi_options['larger_page_numbers_multiple'] = 10;
return $pagenavi_options;
}
add_filter('previous_posts_link_attributes', 'filter_previous_anchor');
function filter_previous_anchor($attr) {
# code...
$attr .= 'class="page-item page-link st"';
return $attr;
}
//hook to add span to the previuos and next
用法
在主题文件夹下新建一个pagenavi.php文件，然后把代码粘贴进去，然后在functions.php里导入文件，
require_once get_template_directory() . '/pagenavi.php';
然后在需要分页的页面添加函数：
tie_get_pagenavi($query)
$query是代表当前的查询，也就是wp_query, 如果是默认的wp_query，也就是没有自定义的wp_query， 就为空，如果你的自定义查询是$the_query，就为$the_query.
