您可以使用WP_Query来做到这一点

You can use WP_Query to do that

尝试以下代码(我没有测试过):

Try this code(i don't tested it):

<?php
$date = '';
$query = 'posts_per_page=9999';
$queryObject = new WP_Query($query);
// The Loop...
if ($queryObject->have_posts()) {
    while ($queryObject->have_posts()) {
        $queryObject->the_post();
                $my_date = the_date('F j', '', '', FALSE);
                if ($my_date!=$date){
                    echo '<h2>'.$my_date.'</h2>';
                    $date = $my_date;
                }
                echo '<h3>';
                the_title();
                echo '</h3>';
                echo '<span>';
                comments_popup_link('No Comments »', '1 Comment »', '% Comments »');
                echo '</span>';
    }
}
?>
