实际上，您不能将与分类法相关的参数传递给get_posts().(Edit: actually, yes you can. The Codex is just somewhat unclear. Looking at source, get_posts() is, at its heart, just a wrapper for WP_Query().) 您可以传递元键/值和post类型，但不能传递诸如post格式之类的分类法。因此，对于这一行：

$myposts = get_posts(\'numberposts=-1&orderby=post_date&order=DESC\');

我建议使用WP_Query() 而不是get_posts():

$myposts = new WP_Query( array(
    \'tax_query\' => array(
        array(                
            \'taxonomy\' => \'post_format\',
            \'field\' => \'slug\',
            \'terms\' => array( 
                \'post-format-aside\',
                \'post-format-audio\',
                \'post-format-chat\',
                \'post-format-gallery\',
                \'post-format-image\',
                \'post-format-link\',
                \'post-format-quote\',
                \'post-format-status\',
                \'post-format-video\'
            ),
            \'operator\' => \'NOT IN\'
        )
    )
) );

注意：是的，有很多嵌套数组。税务查询可能会很棘手。

下一步是修改循环打开/关闭语句。更改这些：

<?php foreach($myposts as $post) : ?>

    <?php /* loop markup goes here */ ?>

<?php endforeach; ?>

。。。为此：

<?php if ( $myposts->have_posts() ) : while ( $myposts->have_posts() ) : $myposts->the_post(); ?>

    <?php /* loop markup goes here */ ?>

<?php endwhile; endif; ?>

<?php wp_reset_postdata(); ?>

实际的循环标记应该能够保持不变，只是不再需要调用setup_postdata( $post ):

<?php        
    $year = mysql2date(\'Y\', $post->post_date);
    $month = mysql2date(\'n\', $post->post_date);
    $day = mysql2date(\'j\', $post->post_date);    
?>

<p>
    <span class="the_article">
        <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
    </span>
    &nbsp;&nbsp;&nbsp;
    <span class="the_day">
        <?php the_time(\'j F Y\'); ?>
    </span>
</p>

所以，把这一切放在一起：

<?php
// Only query posts with the
// "standard" post format, which
// requires *excluding* all other
// post formats, since neither the
// "post_format" taxonomy nor the
// "post-format-standard" taxonomy term
// is applied to posts without
// defined post formats
$myposts = new WP_Query( array(
    \'tax_query\' => array(
        array(                
            \'taxonomy\' => \'post_format\',
            \'field\' => \'slug\',
            \'terms\' => array( 
                \'post-format-aside\',
                \'post-format-audio\',
                \'post-format-chat\',
                \'post-format-gallery\',
                \'post-format-image\',
                \'post-format-link\',
                \'post-format-quote\',
                \'post-format-status\',
                \'post-format-video\'
            ),
            \'operator\' => \'NOT IN\'
        )
    )
) );

// Open the loop
if ( $myposts->have_posts() ) : while ( $myposts->have_posts() ) : $myposts->the_post(); ?>

    $year = mysql2date(\'Y\', $post->post_date);
    $month = mysql2date(\'n\', $post->post_date);
    $day = mysql2date(\'j\', $post->post_date);    
    ?>

    <p>
        <span class="the_article">
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
        </span>
        &nbsp;&nbsp;&nbsp;
        <span class="the_day">
            <?php the_time(\'j F Y\'); ?>
        </span>
    </p>  
    <?php 

// Close the loop
endwhile; endif;

// Reset $post data to default query
wp_reset_postdata();
