这是我实现它的方法,虽然我相信有更好的方法。我将这些函数添加到我的主题的functions.php文件中:
function twentyeleven_get_archives_callback($item, $index, $currYear) {
global $wp_locale;
if ( $item['year'] == $currYear ) {
$url = get_month_link( $item['year'], $item['month'] );
$text = sprintf(__('%1$s %2$d'), $wp_locale->get_month($item['month']), $item['year']);
echo get_archives_link($url, $text);
}
}
function twentyeleven_get_archives() {
global $wpdb;
$query = "SELECT YEAR(post_date) AS `year` FROM $wpdb->posts WHERE `post_type` = 'post' AND `post_status` = 'publish' GROUP BY `year` ORDER BY `year` DESC";
$arcresults = $wpdb->get_results($query);
$years = array();
if ($arcresults) {
foreach ( (array)$arcresults as $arcresult ) {
array_push($years, $arcresult->year);
}
}
$query = "SELECT YEAR(post_date) as `year`, MONTH(post_date) as `month` FROM $wpdb->posts WHERE `post_type` = 'post' AND `post_status` = 'publish' GROUP BY `year`, `month` ORDER BY `year` DESC, `month` ASC";
$arcresults = $wpdb->get_results($query, ARRAY_A);
$months = array();
if ( $arcresults ) {
foreach ($years as $year) {
echo "\t<h2>$year</h2>\n\t<ul>\n";
array_walk($arcresults, "twentyeleven_get_archives_callback", $year);
echo "\t</ul>\n";
}
}
}
您可以在主题中使用以下方式调用此函数,而不是使用wp_get_archives():
<ul>
<?php twentyeleven_get_archives(); ?>
</ul>
函数名可以随意设置,不过最好的做法是以主题名称为前缀(例如,twentyeleven_)。
我参考了wp-includes/general-template.php中的wp_get_archives()和get_archives_link()函数。
