wordpress - 如何获得 Woocommerce 顶级产品类别？

Question

我正在尝试在主页模板中检索顶级产品类别。我使用了下面的代码，但不知道为什么它不起作用。

 <?php
          global $post, $product;
    $taxonomy = 'product_cat'; //Choose the taxonomy
    $terms = get_terms( $taxonomy ); //Get all the terms

    foreach ($terms as $term) { //Cycle through terms, one at a time

    // Check and see if the term is a top-level parent. If so, display it.
    $parent = $term->parent;
     if ( $parent=='0' ) {

      $term_id = $term->term_id; //Define the term ID
      $term_link = get_term_link( $term, $taxonomy ); //Get the link to the archive page for that term
      $term_name = $term->name;
      echo '<a class="ccats" href="' . $term_link . '"><span class="label">' . $term_name . '</span></a>';
    } }
    ?>

请帮助我获取顶级类别。

Answer 1

您只需要在 get_terms() 函数中添加以下参数:

$terms = get_terms( array('taxonomy' => 'product_cat', 'parent' => 0) );

foreach ( $terms as $term ){
    $term_link = get_term_link( $term, $taxonomy );

    echo '<a class="ccats" href="'.$term_link.'"><span class="label">'.$term->name.'</span></a>';
}

这是 all available arguments可以在 get_terms() 函数中使用。
