在WordPress中仅显示一个层级子类别

此代码使用Taxonomy Images 用于显示类别图像的插件。此代码在父类别页面中显示主类别的子类别(category.php), 但我只想在页面中显示一级子类别，例如

硬件（父类别）

监视器（硬件的一级子类别）

三星（二级子类别）

当用户单击硬件链接时，他应该只看到监视器子类别链接，第二次单击监视器时，他应该看到三星类别链接，当他单击三星时，子类别lcd将显示。我应该如何更改此代码以实现我的承诺

我的代码：

<?php
$cat_id = get_query_var(\'cat\');
$catlist = get_categories(\'hide_empty=0&child_of=\' . $cat_id);
echo "<ul>";

foreach($catlist as $categories_item)
{
echo \'<h1><a href="\' . get_category_link( $categories_item->term_id ) . \'" title="\' . sprintf( __( "View all products in %s" ), $categories_item->name ) . \'" \' . \'>\' . $categories_item->name.\'</a> </h1> \';

echo \'<div class="categoryoverview clearfix">\';
    $terms = apply_filters( \'taxonomy-images-get-terms\', \'\' );
    if ( ! empty( $terms ) ) {

      foreach( (array) $terms as $term ) {
        if($term->term_id == $categories_item->term_id) {
           print \'<a href="\' . esc_url( get_term_link( $term, $term->taxonomy ) ) . \'">\' . wp_get_attachment_image( $term->image_id, \'thumbnail\' );
           echo \'</a>\';
        }
    }
    echo \'<p>\'. $categories_item->description; echo \'</p>\';
}
echo \'</div>\';
}
echo "</ul>";
?>

$parent_category = get_categories(array(\'orderby\' => \'name\',\'parent\' => 0)); foreach($categories as $category) { echo \'<p>Category: <a href="\' . get_category_link( $category->term_id ) . \'" title="\' . sprintf( __( "View all posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a> </p> \'; }

$cat_id = get_query_var(\'cat\'); $catlist = apply_filters( \'taxonomy-images-get-terms\', \'\', array( \'parent\' => $cat_id, ) ); foreach ( $catlist as $cat ) { echo \'<a href="\'; echo esc_url( get_term_link( $cat->term_id, $cat->taxonomy ) ); echo \'">\'; echo wp_get_attachment_image( $cat->image_id, \'thumbnail\' ); echo \'<p>\'; echo $cat->description; echo \'</p>\'; echo \'</a>\'; }
