我在尝试获取自定义分类法中的类别时遇到问题
分类=投资组合类别
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，我们以 catA、catB...、catE 为例
我想获取这些类别的名称（catA 等），以便将其用作过滤器函数的类。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：
发现
- $category_slug
- $期限
- $term_id
- $id
我也试过
- 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 <br />";
}
$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 <br />";
$out .= '</div>';
$groupCount = -1;
}
}
if($groupCount==0 || $groupCount==1){
//echo $groupCount." -close row final <br />";
$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，我认为这可能会给我们一个线索，脚本如何根据指定的自定义类别（catA 等）找到相关帖子
