我几乎从零碎的工作中得到了我想要的东西，但我需要一些帮助来完成它。我尝试在页面模板（而不是单独的归档页面）中输出以下内容（对于自定义帖子类型）：

<ul class="accordion">
<li>
    <h3>2014</h3>
    <div>
        <p>12 September 2014</p>
        <a href="the_permalink>"Post title 1</a>
    </div>
    <div>
        <p>11 August 2014</p>
        <a href="the_permalink>"Post title 2</a>
    </div>
    <div>
        <p>10 May 2014</p>
        <a href="the_permalink>"Post title 3</a>
    </div>
</li>
<li>
    <h3>2013</h3>
    <div>
        <p>20 June 2013</p>
        <a href="the_permalink>"Post title 4</a>
    </div>
    <div>
        <p>19 April 2013</p>
        <a href="the_permalink>"Post title 5</a>
    </div>
    <div>
        <p>18 January 2013</p>
        <a href="the_permalink>"Post title 6</a>
    </div>
</ul>

到目前为止，我得到的代码如下所示：

<?php
$years = $wpdb->get_results( "SELECT YEAR(post_date) AS year FROM wp_posts WHERE post_type = \'press-releases\' AND post_status = \'publish\' GROUP BY year DESC" );

foreach ( $years as $year ) {
    $posts_this_year = $wpdb->get_results( "SELECT post_title FROM wp_posts WHERE post_type = \'press-releases\' AND post_status = \'publish\' AND YEAR(post_date) = \'" . $year->year . "\'" );

    echo \'<ul class="accordion">\';
    echo \'<li><h3>\' . $year->year . \'</h3>\';
    foreach ( $posts_this_year as $post ) {
        echo \'<div>\' . $post->post_title . \'</div>\';
    }
    echo \'</li>\';
    echo \'</ul>\';
}
?>

这是我想要的基本内容。然而，我还需要将文章标题包装在永久链接中，并输出文章发布的日期。我相信这是一个简单的解决方案，但我不知道怎么做。有什么想法或者有没有更好的方法来实现我想要实现的目标？

感谢您的任何意见！

<?php

$posts = new WP_Query(
    array(
        \'posts_per_page\' => -1,
        \'post_type\' => \'press-releases\'
    )
);

if ( $posts->have_posts() ) : ?>

    <ul class="accordion"><?php

        while ( $posts->have_posts() ) : $posts->the_post();
            $year = get_the_time( \'Y\' );

            if ( $posts->current_post === 0 )
                printf( \'<li><h3>%s</h3>\', $year ); // First post, always open the <li>
            elseif ( $last_year !== $year )
                printf( \'</li><li><h3>%s</h3>\', $year ); // Unlike above, close the previous open <li>

        ?>

            <div>
                <p><?php the_time( \'j F Y\' ) ?></p>
                <a href="<?php the_permalink() ?>"><?php the_title() ?></a>
            </div>

        <?php           

            if ( ( $posts->current_post + 1 ) === $posts->post_count )
                echo \'</li>\'; // Always close the <li> at the end of the loop

            $last_year = $year;

        endwhile;

    ?></ul>
