BY BIGFA：上次写的时光轴归档流传范围之广远超我的想象，但是已经因为某些原因西去了，自从恢复博客我也没新建归档页面，恰好看见z大写了写的归档，琢磨着自己也写一个，考虑到按照时间的已经没什么可折腾的了索性写了个按照分类的。

感受地址：http://www.lesliehsia.com/archive

说明

CSS 隐藏了部分文章，使每个分类只显示5篇文章，当然hover 的时候会全部显示
函数自带一个hide_empty参数，是否隐藏没有文章的分类

实现方法

下面的代码加入到functions.php中

function get_archive_by_category($hide_empty = false){
$output = ‘<div class=”archive-category-groups”>’;
$cateargs = array(
‘hide_empty’ => $hide_empty
);
$categories = get_categories($cateargs);
foreach($categories as $category) {
$output .= ‘<div class=”archive-category-group”><h2 class=”archive-category-title”><a href=”‘ . get_category_link( $category->term_id ) . ‘” title=”‘ . $category->name . ‘” ‘ . ‘>’ . $category->name.'</a> </h2><h3 class=”archive-category-description”>’. $category->description . ‘</h3><div class=”archive-category-postcount v-textAlignCenter”>’. $category->count . ‘</div>’;
$args = array(
‘category’ => $category->term_id,
‘numberposts’ => -1
);
$output .= ‘<div class=”archive-category-posts”>’;
$posts = get_posts($args);
foreach($posts as $post){
$output .= ‘<div class=”archive-category-post”><a class=”archive-category-post-title” href=”‘.get_permalink($post->ID).'”>’.$post->post_title.'</a><time class=”archive-category-post-time”>’.human_time_diff(strtotime($post->post_date_gmt),time()).’ ago </time></div>’;
}
$output .= ‘</div></div>’;
}
return $output;

}
function archive_by_category_shortcode($atts, $content=null){
extract( shortcode_atts( array(
‘hide_empty’ => false,
),
$atts ) );
return get_archive_by_category($hide_empty);
}
add_shortcode(‘archivebc’,’archive_by_category_shortcode’);
