我试图在WordPress中使用一种称为“案例研究”的自定义分类法来显示所有类别的最新x帖子。
我已经成功地将所有类别名称输出为标题链接。我还输出了一些来自标准帖子分类法的帖子，这些帖子属于正确的类别，但我无法显示我的“案例研究”分类法中的任何内容。当我添加\'post_type\' => \'case-studies\' 到$post_args 查询它不显示任何结果。
if (have_posts()) :
$tax = \'case-studies\';
$cat_args = array(
\'orderby\' => \'name\',
\'order\' => \'ASC\'
);
$categories = get_terms($tax, $cat_args);
foreach($categories as $category) {
echo \'<p><a href="\' . get_term_link( $category, $tax ) . \'" title="\'
. sprintf( __( "View all posts in %s" ), $category->name ) . \'" \'
. \'>\' . $category->name.\'</a></p>\';
$post_args = array(
\'posts_per_page\' => 10,
\'category_name\' => $category->name
);
$posts = get_posts($post_args);
foreach($posts as $post) { ?>
<a href="<?php echo get_the_permalink(); ?>"><?php echo get_the_title(); ?></a><br/>
<?php }
echo \'<p><a href="\' . get_term_link( $category, $tax ) . \'" title="\'
. sprintf( __( "View all posts in %s" ), $category->name ) . \'" \'
. \'>View all posts in \' . $category->name.\'</a></p>\';
}
endif;

类别参数不适用于自定义分类法。您需要使用tax_query 相反
在当前代码中，替换（，它在任何情况下都被错误使用，category_name 采用slug, 不name)
\'category_name\' => $category->name
使用
\'post_type\' => \'case-studies\',
\'tax_query\' => array(
array(
\'taxonomy\' => $tax
\'terms\' => $category->term_id,
\'include_children\' => false
)
),

此代码显示所有类别的所有帖子location taxonomy 对于custom post type testaismgallery.
$args = array(
\'number\' => $number,
\'hide_empty\' => $hide_empty,
\'include\' => $ids
);
$custom_categories = get_terms( \'location\', $args );
foreach ( $custom_categories as $catterm){
$arg = Array(
\'post_type\' => \'testaismgallery\',
\'posts_per_page\' => \'-1\',
\'post_status\' => \'publish\',
\'tax_query\' => Array( Array (
\'taxonomy\' => \'location\' ,
\'terms\' => $catterm->term_id
)) );
$loop = new WP_Query( $arg );
global $post;
?>
<?php
while ( $loop->have_posts() ) : $loop->the_post();
?>
<div class="gallery-content">
<div class="entry-content">
<?php
$post_id = get_the_ID();
$abc = get_post_meta($post_id, event_file, true);
echo "<li><img src=\'".$abc. "\' ></li> ";
?>
</div>
</div>
<?php endwhile;
}
?>
