wordpress, get category names for a custom post type
提问by Pectus Excavatum
Is there a better way to get the category names for a custom post type in wordpress?
有没有更好的方法来获取 wordpress 中自定义帖子类型的类别名称？
<?php // get the portfolio categories
$terms = get_the_terms( $post->ID, 'filters' );
if ( $terms && ! is_wp_error( $terms ) ) :
$names = array();
$slugs = array();
foreach ( $terms as $term ) {
$names[] = $term->name;
$slugs[] = $term->slug;
}
$name_list = join( " / ", $names );
$slug_list = join( " category-", $slugs );
endif;
?>
<!-- BEGIN portfolio-item-->
<li class="portfolio-item third column category-<?php echo $slug_list; ?>" data-filter="category-<?php echo $slug_list; ?>">

<?php
$taxonomy = 'filters';
$terms = get_terms($taxonomy);
if ( $terms && !is_wp_error( $terms ) ) :
?>
<ul>
<?php foreach ( $terms as $term ) { ?>
<li><a href="<?php echo get_term_link($term->slug, $taxonomy); ?>"><?php echo $term->name; ?></a></li>
<?php } ?>
</ul>
<?php endif;?>
Or in fuctions.php place this:
或者在 fuctions.php 中放置：
function get_the_category_custompost( $id = false, $tcat = 'category' ) {
$categories = get_the_terms( $id, $tcat );
if ( ! $categories )
$categories = array();
$categories = array_values( $categories );
foreach ( array_keys( $categories ) as $key ) {
_make_cat_compat( $categories[$key] );
}
return apply_filters( 'get_the_categories', $categories );
}
and call the function as:
并将函数调用为：
<?php $cat = get_the_category_custompost($post->ID, 'Your Custom Taxonomy'); ?>

My answer seems too simple, but I used this to list the categories from a wordpress plugin called DW Question Answerthat has separate categories from the standard wp categories.
我的答案似乎太简单了，但我用它来列出名为DW Question Answer的 wordpress 插件中的类别，该插件具有与标准 wp 类别不同的类别。
I am assuming that Design Wall used custom post types to create the q&a part and taxonomies to create the categories.
我假设 Design Wall 使用自定义帖子类型来创建问答部分和分类法来创建类别。
<ul>
<?php wp_list_categories('taxonomy=dwqa-question_category&hide_empty=0&orderby=id&title_li=');?>
</ul>

Assuming your custom taxonomy is recipegroups, i have implemented and tested this code in functions.php and i am sure that it will work in plugins too.
假设您的自定义分类法是 recipegroups，我已经在 functions.php 中实现并测试了这段代码，我相信它也可以在插件中工作。
$recipeTerms = get_terms(array(
'taxonomy' => 'recipegroups',
));
foreach($recipeTerms as $recipeTerm){
if($recipeTerm->parent==0){
echo "<div class='termsBox'>"; // remove these div's to suit your needs..
$termLink =get_term_link( $recipeTerm );
echo "<a href='$termLink'><div class='termParent'>".$recipeTerm->name."</div></a> ";
$termChilds = get_term_children($recipeTerm->term_id, 'recipegroups' );
foreach($termChilds as $child){
$chTerm = get_term_by( 'id', $child, 'recipegroups');
$termLink =get_term_link( $chTerm );
echo "<a href='$termLink'><div class='top-cat-items'>".$chTerm->name."</div></a>";
}
echo "</div>"; // end of termsBox div
}
}
