为了满足您的要求，您需要修改 Wordpress 重写，以便能够捕获自定义帖子类型的年/月/等帖子数据。
您可以使用以下代码执行此操作：
/**
* Custom post type date archives
*/
/**
* Custom post type specific rewrite rules
* @return wp_rewrite Rewrite rules handled by Wordpress
*/
function cpt_rewrite_rules($wp_rewrite) {
$rules = cpt_generate_date_archives('news', $wp_rewrite);
$wp_rewrite->rules = $rules + $wp_rewrite->rules;
return $wp_rewrite;
}
add_action('generate_rewrite_rules', 'cpt_rewrite_rules');
/**
* Generate date archive rewrite rules for a given custom post type
* @param string $cpt slug of the custom post type
* @return rules returns a set of rewrite rules for Wordpress to handle
*/
function cpt_generate_date_archives($cpt, $wp_rewrite) {
$rules = array();
$post_type = get_post_type_object($cpt);
$slug_archive = $post_type->has_archive;
if ($slug_archive === false) return $rules;
if ($slug_archive === true) {
$slug_archive = $post_type->name;
}
$dates = array(
array(
'rule' => "([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})",
'vars' => array('year', 'monthnum', 'day')),
array(
'rule' => "([0-9]{4})/([0-9]{1,2})",
'vars' => array('year', 'monthnum')),
array(
'rule' => "([0-9]{4})",
'vars' => array('year'))
);
foreach ($dates as $data) {
$query = 'index.php?post_type='.$cpt;
$rule = $slug_archive.'/'.$data['rule'];
$i = 1;
foreach ($data['vars'] as $var) {
$query.= '&'.$var.'='.$wp_rewrite->preg_index($i);
$i++;
}
$rules[$rule."/?$"] = $query;
$rules[$rule."/feed/(feed|rdf|rss|rss2|atom)/?$"] = $query."&feed=".$wp_rewrite->preg_index($i);
$rules[$rule."/(feed|rdf|rss|rss2|atom)/?$"] = $query."&feed=".$wp_rewrite->preg_index($i);
$rules[$rule."/page/([0-9]{1,})/?$"] = $query."&paged=".$wp_rewrite->preg_index($i);
}
return $rules;
}
你会注意到我已经硬编码news到$rules = cpt_generate_date_archives('news', $wp_rewrite);代码的一部分。您可以根据需要更改此设置。
使用此代码，您应该能够导航到http://yoursite.com/news/2013/02/并在特定时间接收该特定帖子类型的存档列表。
为了完整起见，我将介绍如何生成每月存档小部件以使用它。
/**
* Get a montlhy archive list for a custom post type
* @param string $cpt Slug of the custom post type
* @param boolean $echo Whether to echo the output
* @return array Return the output as an array to be parsed on the template level
*/
function get_cpt_archives( $cpt, $echo = false )
{
global $wpdb;
$sql = $wpdb->prepare("SELECT * FROM $wpdb->posts WHERE post_type = %s AND post_status = 'publish' GROUP BY YEAR($wpdb->posts.post_date), MONTH($wpdb->posts.post_date) ORDER BY $wpdb->posts.post_date DESC", $cpt);
$results = $wpdb->get_results($sql);
if ( $results )
{
$archive = array();
foreach ($results as $r)
{
$year = date('Y', strtotime( $r->post_date ) );
$month = date('F', strtotime( $r->post_date ) );
$month_num = date('m', strtotime( $r->post_date ) );
$link = get_bloginfo('siteurl') . '/' . $cpt . '/' . $year . '/' . $month_num;
$this_archive = array( 'month' => $month, 'year' => $year, 'link' => $link );
array_push( $archive, $this_archive );
}
if( !$echo )
return $archive;
foreach( $archive as $a )
{
echo '<li><a href="' . $a['link'] . '">' . $a['month'] . ' ' . $a['year'] . '</a></li>';
}
}
return false;
}
要使用此功能，只需提供自定义帖子类型的 slug，即：get_cpt_archives( 'news' )。这将返回一组唯一的年份/日期/链接，即：
Array
(
[0] => Array
(
[month] => February
[year] => 2013
[link] => http://yoursite.com/news/2013/02
)
[1] => Array
(
[month] => January
[year] => 2013
[link] => http://yoursite.com/news/2013/01
)
)
您可以使用 a 循环遍历这些内容foreach并根据需要输出它们。
或者，您可以使用get_cpt_archives( 'news', true )which 将自动回显包装在<li>指向其特定存档的链接中的每个项目。
输出的格式不是你想要的，所以你必须稍微调整一下才能让它显示在
Year
Month
Month
Year
Month
您需要的格式。
我希望这有帮助。
