WordPress 如何實現分頁導航？

05-01

想自己實現的話...直接看 WP-PageNavi 的源碼就是了。

很容易. 了解下wp的自定義模版就可以了.

可以看看這篇文章：覺唯主題自動翻頁改成手動翻頁，裡面的方法適用於所以的主題。推薦看看。

我想問一下如果不增加插件，如何能實現。。。

wordpress自帶的主題很多都沒有自帶分頁的功能，即便有也很弱，只有更早和更新，我自己使用的主題頁有這個問題，可以使用WP-PageNavi插件，可以對顯示效果進行調整。推薦使用。

我的是用以下代碼實現的：

/*分頁代碼*/

/* Function that Rounds To The Nearest Value.

Needed for the pagenavi() function */

function round_num($num, $to_nearest) {

/*Round fractions down (PHP: floor - Manual)*/

return floor($num/$to_nearest)*$to_nearest;

}

/* Function that performs a Boxed Style Numbered Pagination (also called Page Navigation).

Function is largely based on Version 2.4 of the WP-PageNavi plugin */

function wp_pagenavi($before = , $after = ) {

global $wpdb, $wp_query;

$pagenavi_options = array();

$pagenavi_options[pages_text] = ();

$pagenavi_options[current_text] = %PAGE_NUMBER%;

$pagenavi_options[page_text] = %PAGE_NUMBER%;

$pagenavi_options[first_text] = ();

$pagenavi_options[last_text] = ();

$pagenavi_options[next_text] = #8250;;

$pagenavi_options[prev_text] = #8249; ;

$pagenavi_options[dotright_text] = ...;

$pagenavi_options[dotleft_text] = ...;

$pagenavi_options[num_pages] = 5; //continuous block of page numbers

$pagenavi_options[always_show] = 0;

$pagenavi_options[num_larger_page_numbers] = 3;

$pagenavi_options[larger_page_numbers_multiple] = 10;

//If NOT a single Post is being displayed

/*Function Reference/is single ? WordPress Codex)*/

if (!is_single()) {

$request = $wp_query-&>request;

//intval — Get the integer value of a variable

/*PHP: intval - Manual*/

$posts_per_page = intval(get_query_var(posts_per_page));

//Retrieve variable in the WP_Query class.

/*Function Reference/get query var ? WordPress Codex*/

$paged = intval(get_query_var(paged));

$numposts = $wp_query-&>found_posts;

$max_page = $wp_query-&>max_num_pages;

//empty — Determine whether a variable is empty

/*PHP: empty - Manual*/

if(empty($paged) || $paged == 0) {

$paged = 1;

}

$pages_to_show = intval($pagenavi_options[num_pages]);

$larger_page_to_show = intval($pagenavi_options[num_larger_page_numbers]);

$larger_page_multiple = intval($pagenavi_options[larger_page_numbers_multiple]);

$pages_to_show_minus_1 = $pages_to_show - 1;

$half_page_start = floor($pages_to_show_minus_1/2);

//ceil — Round fractions up (PHP: ceil - Manual)

$half_page_end = ceil($pages_to_show_minus_1/2);

$start_page = $paged - $half_page_start;

if($start_page &<= 0) {

$start_page = 1;

}

$end_page = $paged + $half_page_end;

if(($end_page - $start_page) != $pages_to_show_minus_1) {

$end_page = $start_page + $pages_to_show_minus_1;

}

if($end_page &> $max_page) {

$start_page = $max_page - $pages_to_show_minus_1;

$end_page = $max_page;

}

if($start_page &<= 0) {

$start_page = 1;

}

$larger_per_page = $larger_page_to_show*$larger_page_multiple;

//round_num() custom function - Rounds To The Nearest Value.

$larger_start_page_start = (round_num($start_page, 10) + $larger_page_multiple) - $larger_per_page;

$larger_start_page_end = round_num($start_page, 10) + $larger_page_multiple;

$larger_end_page_start = round_num($end_page, 10) + $larger_page_multiple;

$larger_end_page_end = round_num($end_page, 10) + ($larger_per_page);

if($larger_start_page_end - $larger_page_multiple == $start_page) {
