您只需使用WP_Query. 您只需确保您使用的是自定义分类法还是内置类别。有关参考，请参阅：Is There a Difference Between Taxonomies and Categories?

下面是一个自定义分类的示例（这也可以用于内置类别，只需更改\'taxonomy\' => \'MY_CUSTOM_TAXONOMY\', 到\'taxonomy\' => \'category\',):

$args = array(
    \'post_type\' => \'MY_CUSTOM_POST_TYPE\',
    \'posts_per_page\' => -1,
    \'orderby\' => \'title\',
    \'order\' => \'DESC\',
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'MY_CUSTOM_TAXONOMY\',
            \'field\'    => \'slug\',
            \'terms\'    => \'THE_SLUG_FROM_MY_TERM\',
        ),
    ),
);

$the_query = new WP_Query( $args );

// The Loop
    echo \'<ul>\';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo \'<li>\' . get_the_title() . \'</li>\';
    }
    echo \'</ul>\';

/* Restore original Post Data */
wp_reset_postdata();

对于单个术语，还可以直接使用查询变量，因此可以更改$args 像这样的事情

$args = array(
    \'post_type\' => \'MY_CUSTOM_POST_TYPE\',
    \'posts_per_page\' => -1,
    \'orderby\' => \'title\',
    \'order\' => \'DESC\',
    \'MY_CUSTOM_TAXONOMY\'    => \'THE_SLUG_FROM_MY_TERM\',
);

如果您有内置类别，请更改$args 至以下内容

$args = array(
    \'post_type\' => \'MY_CUSTOM_POST_TYPE\',
    \'posts_per_page\' => -1,
    \'orderby\' => \'title\',
    \'order\' => \'DESC\',
    \'cat\'    => \'THE_ID_OF_YOUR_CATEGORY\',
);
