我有一个自定义帖子类型下的帖子，我喜欢在按年份和月份分组的页面中显示。在我创建的页面模板中，我设法按月份将它们分开，但仍然没有在不同的级别进行分组（它们都是相同的级别，只有月份名称作为组之间的分隔符），like so:
<div class="month"></div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
<div class="month"></div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
<div class="month"></div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
<div>post title</div>
I did that with:
<?php
global $more; $more = false; # some wordpress wtf logic
$posts = get_posts(array(
\'post_type\' => \'press\',
\'nopaging\' => true,
\'orderby\' => \'date\',
\'order\' => \'DSC\',
\'posts_per_page\' => 999999,
));
$month = null;
foreach($posts as $post):
setup_postdata($post); //enables the_title() etc. without specifying a post ID
$postMonth = date(\'FY\',strtotime($post->post_date));
if($month!=$postMonth){
echo \'<div class="month">\'.date(\'F Y\',strtotime($post->post_date)).\'</div>\';
$month =$postMonth;
} ?>
<div><a href="<?php the_field(\'url\');?>">"<?php the_title();?>"</a></div>
<?php endforeach;?>
What I want to have is something like this:
<div class="year">
<span>2019</span>
<div class="month">
<span>August</span>
<div>post title</div>
<div>post title</div>
</div>
</div>
<div class="year">
<span>2019</span>
<div class="month">
<span>July</span>
<div>post title</div>
<div>post title</div>
</div>
</div>
<div class="year">
<span>2018</span>
<div class="month">
<span>January</span>
<div>post title</div>
<div>post title</div>
</div>
</div>
我尝试了StackExchange上的所有解决方案，但都没有成功。有什么想法吗？

您可以这样做：
global $post;
$posts = get_posts( array(
\'post_type\' => \'press\',
\'nopaging\' => true,
\'orderby\' => \'date\',
\'order\' => \'DESC\', // it\'s DESC; not DSC
// There\'s no use setting posts_per_page when nopaging is enabled.
// Because posts_per_page will be ignored when nopaging is enabled.
) );
$_year_mon = \'\'; // previous year-month value
$_has_grp = false; // TRUE if a group was opened
foreach ( $posts as $post ) {
setup_postdata( $post );
$time = strtotime( $post->post_date );
$year = date( \'Y\', $time );
$mon = date( \'F\', $time );
$year_mon = "$year-$mon";
// Open a new group.
if ( $year_mon !== $_year_mon ) {
// Close previous group, if any.
if ( $_has_grp ) {
echo \'</div><!-- .month -->\';
echo \'</div><!-- .year -->\';
}
$_has_grp = true;
echo \'<div class="year">\';
echo "<span>$year</span>";
echo \'<div class="month">\';
echo "<span>$mon</span>";
}
// Display post title.
if ( $title = get_the_title() ) {
echo "<div>$title</div>";
} else {
echo "<div>#{$post->ID}</div>";
}
$_year_mon = $year_mon;
}
// Close the last group, if any.
if ( $_has_grp ) {
echo \'</div><!-- .month -->\';
echo \'</div><!-- .year -->\';
}
wp_reset_postdata();
