我的团队类型中有以下代码。我用来为成员信息创建自定义分类法的php文件：

function create_team_taxonomies() {
    $labels = array(
        \'name\'              => _x( \'Kategooriad\', \'taxonomy general name\' ),
        \'singular_name\'     => _x( \'Kategooria\', \'taxonomy singular name\' ),
        \'search_items\'      => __( \'Otsi kategooriatest\' ),
        \'all_items\'         => __( \'Kõik kategooriad\' ),
        \'parent_item\'       => __( \'Vanem kategooria\' ),
        \'parent_item_colon\' => __( \'Vanem kategooria:\' ),
        \'edit_item\'         => __( \'Muuda kategooriat\' ),
        \'update_item\'       => __( \'Uuenda kategooriat\' ),
        \'add_new_item\'      => __( \'Lisa uus kategooria\' ),
        \'new_item_name\'     => __( \'Uus kategooria nimi\' ),
        \'menu_name\'         => __( \'Kategooriad\' ),
    );

    $args = array(
        \'hierarchical\'      => true, // Set this to \'false\' for non-hierarchical taxonomy (like tags)
        \'labels\'            => $labels,
        \'show_ui\'           => true,
        \'show_admin_column\' => true,
        \'query_var\'         => true,
        \'rewrite\'           => array( \'slug\' => \'categories\' ),
    );

    register_taxonomy( \'team_categories\', array( \'team\' ), $args );
}
add_action( \'init\', \'create_team_taxonomies\', 0 );

但当我调用page team中的查询时。php使用以下方式：

<?php query_posts( \'post_type=team&cat=noukogu&showposts=15\' ); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<?php $title=s tr_ireplace( \'"\', \'\', trim(get_the_title())); $desc=s tr_ireplace( \'"\', \'\', trim(get_the_content())); ?>

<div class="member">

    <img class="image" src="<?php print team_thumbnail_url($post->ID) ?>" alt="liikme pilt">

    <h3 class="title"><?php echo $title; ?></h3>
    <p class="description">
        <?php echo $desc; ?>
    </p>

</div>
<!-- End member -->

<?php endwhile; endif; ?>

所有成员帖子都会显示出来。不是noukogu 类别职位。

你知道是什么导致了这个问题吗？

UPDATE: 我现在明白了cat 用于类别ID，但当我将其更改为category_name（使用类别slug）根本没有帖子显示。

<?php
$tax_query =  array(
                 \'taxonomy\' => \'team_categories\',
                 \'field\'    => \'slug\',
                 \'terms\'    => \'noukogu\'
              );

$args = array(
    \'post_type\' => \'team\',
    \'tax_query\' => array( $tax_query ),
 );

$query = new WP_Query( $args );

if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();

        $title = str_ireplace( \'"\', \'\', trim(get_the_title())); $desc=str_ireplace( \'"\', \'\', trim(get_the_content()));
        ?>

        <div class="member">
          <img class="image" src="<?php print team_thumbnail_url($post->ID) ?>" alt="liikme pilt">
           <h3 class="title"><?php echo $title; ?></h3>
            <p class="description">
                <?php echo $desc; ?>
            </p>

      </div>
      <!-- End member -->

   <?php
   }
}

wp_reset_postdata();
?>

$args = array(
    \'post_type\' => \'team\',
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'team_categories\',
            \'field\'    => \'slug\',
            \'terms\'    => \'SLUG FOR PARTICULAR TERM\',
        ),
    ),
);
$query = new WP_Query( $args );
