我试图在自定义分类中获取类别时遇到问题
分类学= portfolio_categories
我通过这个插件创建了5个新类别：https://wordpress.org/plugins/hero-portfolio/
5个新类别，让我们以catA，catB ...，catE为例
我想得到这些类别的名称（catA等），以便将其用作过滤函数的类 . 当我尝试通过各种方法显示值时，根本没有输出 . 这些是我尝试过的：
查找
-
$ category_slug
-
$ term
-
$ term_id
-
$ id
我也试过了
-
get_category_by_slug（'category-slug'）
-
get_term_by（'slug'，$ value，$ taxonomy）
这是代码：
if($category_slug!=''){
$term = term_exists($category_slug);
if ($term == 0 || $term == null) {
echo "The ".$category_slug." does not exist!";
return;
}
$term_id = $term;
if(is_array($term)){
$term_id = $term['term_id'];
}
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'portfolio_categories',
'field' => 'id',
'terms' => $term_id
)
)
);
$rx_query = array_merge($rx_query, $args);
}
$labels = PluginOptions::getInstance()->getLabels();
$out = '<div class="rx_hero_portfolio container-fluid">';
$query = new WP_Query($rx_query);
if($query->have_posts()) {
$groupCount = -1;
while($query->have_posts()){
$groupCount++;
if($groupCount==0){
$out .= '<div class="row">';
//echo $groupCount." -open row
";
}
$query->the_post();
$id = get_the_ID();
$post_options = new RxPostOptions($id);
$thumbnail_url = $post_options->getFeaturedImage($id, 800, 650);
$title = get_the_title($id);
$date = get_the_date(Y);
$term = get_term( $id, $taxonomy );
$out .= '
<div class="col-md-4 hero_thumb_ui '. $term .'">
<div class="hero_thumb_container"><a href="'.get_permalink($id).'" class="hero_thumb_image_link"><img src="'.$thumbnail_url.'" alt="" /></a></div>
<div class="rx_hero_hoverui">
<h3 class="rx_hero_thumb_title">'.$title.'</h3>
<p class="rx_hero_excerpt">'.$post_options->get_the_excerpt_max_charlength($post_options->getExcerptThreeCols()).'</p>
<p class="rx_hero_excerpt">'. $date .'</p>
<div class="read_more_ui_bottom">
<a class="rx_hero_read_more" href="'.get_permalink($id).'">'.$labels['readMoreLB'].'</a>
</div>
</div>
</div>
';
if($groupCount==2){
//echo $groupCount." -close row
";
$out .= '</div>';
$groupCount = -1;
}
}
if($groupCount==0 || $groupCount==1){
//echo $groupCount." -close row final
";
$out .= '</div>';
}
} else {
// no posts found
//echo "no posts found";
}
/* Restore original Post Data */
wp_reset_postdata();
$out .= '</div>';
return $out;
}
这是代码的另一部分，我认为这可能会让我们知道脚本如何根据指定的自定义类别找到相关的帖子（catA等）
