在中运行条件检查foreach 循环使用is_category($term-name)

将类变量指定给active 如果它与$term->name

$terms = get_terms( \'category\' );
echo \'<ul>\';
foreach ( $terms as $term ) {
    $class = ( is_category( $term->name ) ) ? \'active\' : \'\'; // assign this class if we\'re on the same category page as $term->name
    echo \'<li><a href="\' . get_term_link( $term ) . \'" class="\' . $class . \'">\' . $term->name . \'</a></li>\';
}
echo \'</ul>\';

我也有同样的问题，下面的解决方案帮助了我。我希望我能帮忙

$curTerm = $wp_query->queried_object;
$terms   = get_terms( \'product-category\' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ) {
    foreach ( $terms as $term ) {
        $classes = array();
        if ( $term->name == $curTerm->name ) {
            $classes[] = \'active\';
        }
        echo \'<li class="\' . implode( \' \', $classes ) . \'"><a href="\' . get_term_link( $term ) . \'">\' . $term->name . \'</a></li>\';
    }
}

此版本使用is_tax 专门检查分类的函数。

$terms = get_terms( array(
  \'taxonomy\' => \'video-category\',
  \'hide_empty\' => false
) );

if (!empty( $terms ) && ! is_wp_error($terms)){
  foreach ( $terms as $term ) {
    $class = ( is_tax(\'video-category\', $term->slug) ) ? \'cat-item current-cat\' : \'cat-item\';
    echo \'<li class="\'.$class.\'"><a href="\' . get_term_link( $term ) .\'">\' . $term->name . \'</a></li>\';
}
