WP-PageNavi是WP的一个优秀的分页导航插件，相信70-80%的P友，一定在用这个插件。
翠花，上图，这个插件的显示效果，是十分的漂亮的。
不过，作为骨灰级的WP狂热者，相信一定不愿意在自己WP站上，被一堆的插件插来插去的。你一定是以最精简作为你的终身目标的，或许你不是，但我是！
废话少说，今天，在这里分享一个将分页导航功能直接写入WP主题的方法，希望对各位骨灰级朋友有用。
第一步，找到所用模板中的function.php文件。打开后。将下边代码用力的插进去！注意！要插在<?php………………?>中省略号处，别插错地方了！
function wp_pagenavi($before = '', $after = '') {
global $wpdb, $wp_query;
if (!is_single()) {
$request = $wp_query->request;
$posts_per_page = intval(get_query_var('posts_per_page'));
$paged = intval(get_query_var('paged'));
$pagenavi_options = get_option('pagenavi_options');
$numposts = $wp_query->found_posts;
$max_page = $wp_query->max_num_pages;
if(empty($paged) || $paged == 0) {
$paged = 1;
}
$pages_to_show = intval($pagenavi_options['num_pages']);
$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 <= 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) {
$start_page = 1;
}
if($max_page > 1 || intval($pagenavi_options['always_show']) == 1) {
$pages_text = str_replace("%CURRENT_PAGE%", $paged, $pagenavi_options['pages_text']);
$pages_text = str_replace("%TOTAL_PAGES%", $max_page, $pages_text);
echo $before.'<div >'."n";
switch(intval($pagenavi_options['style'])) {
case 1:
if(!empty($pages_text)) {
echo '<span >'.$pages_text.'</span>';
}
if ($start_page >= 2 && $pages_to_show < $max_page) {
if(!empty($pagenavi_options['dotleft_text'])) {
echo '<span >'.$pagenavi_options['dotleft_text'].'</span>';
}
}
previous_posts_link($pagenavi_options['prev_text']);
for($i = $start_page; $i <= $end_page; $i++) {
if($i == $paged) {
$current_page_text = str_replace("%PAGE_NUMBER%", $i, $pagenavi_options['current_text']);
echo '<span >'.$current_page_text.'</span>';
} else {
$page_text = str_replace("%PAGE_NUMBER%", $i, $pagenavi_options['page_text']);
echo '<a href="'.clean_url(get_pagenum_link($i)).'" title="'.$page_text.'">'.$page_text.'</a>';
}
}
next_posts_link($pagenavi_options['next_text'], $max_page);
if ($end_page < $max_page) {
if(!empty($pagenavi_options['dotright_text'])) {
echo '<span >'.$pagenavi_options['dotright_text'].'</span>';
}
$last_page_text = str_replace("%TOTAL_PAGES%", $max_page, $pagenavi_options['last_text']);
echo '<a href="'.clean_url(get_pagenum_link($max_page)).'" title="'.$last_page_text.'">'.$last_page_text.'</a>';
}
break;
case 2;
echo '<form action="'.htmlspecialchars($_SERVER['PHP_SELF']).'" method="get">'."n";
echo '<select size="1" = this.options[this.selectedIndex].value;">'."n";
for($i = 1; $i <= $max_page; $i++) {
$page_num = $i;
if($page_num == 1) {
$page_num = 0;
}
if($i == $paged) {
$current_page_text = str_replace("%PAGE_NUMBER%", $i, $pagenavi_options['current_text']);
echo '<option value="'.clean_url(get_pagenum_link($page_num)).'" selected="selected" >'.$current_page_text."</option>n";
} else {
$page_text = str_replace("%PAGE_NUMBER%", $i, $pagenavi_options['page_text']);
echo '<option value="'.clean_url(get_pagenum_link($page_num)).'">'.$page_text."</option>n";
}
}
echo "</select>n";
echo "</form>n";
break;
}
echo '</div>'.$after."n";
}
}
}
第二步：找到你想加入分页导航的页面，如首页、分类页等。再用力的插入如下代码：
第三步：找到你的CSS文件，再次用力的插入如下代码：
/* Page Navigation
---------------------------------------------*/
.navigation {
padding-top:15px;
padding-bottom:2px;/*visivility-IE*/
border:1px solid #fff;
}
.alignleft {
float:left;
}
.alignright {
float:right;
}
.aligncenter, div.aligncenter {
display: block;
margin:0 auto;
}
.wp-pagenavi {
text-transform:uppercase;
}
.wp-pagenavi a {
text-decoration:none;
border:1px solid #b3b3b3;
color:#212236;
margin:2px;
padding:2px 6px;
}
.wp-pagenavi a:hover {
color:#fff;
background-color:#9c0;
}
.wp-pagenavi span {
border:1px solid #b3b3b3;
margin:2px;
padding:2px 6px;
}
.wp-pagenavi span.pages {
color:#777;
margin-left:0;
color:#000;
word-spacing:0.2em;
}
.wp-pagenavi span.current {
color:#212236;
background-color:#e8edef;
}
至此，WP分页导航大法修炼成功。注意：功夫一定要做足，一定要插三次，一次都不能少！
