Question

如果试图让Wordpress通过基于父母的子标题列表，但它的所有内容只是一个或两个标题。有什么建议吗？

以下代码

function get_categories_list() {
    $parent = $child = array();
    foreach (get_the_category(get_the_id()) as $cat) {
        if ($cat->id === 0) {
            continue;
        }
        if ($cat->category_parent === 0) {
            array_push($parent,$cat);
        } else {
            array_push($child,$cat);
        }
    }
    foreach ($parent as $key => $cat) {
        if ($key !== 0) {
            echo "-";
        }
        echo '<a href="' . get_category_link( $cat->category_parent ) .'"> ' . $cat->name . '</a>';
    }
    foreach ($child as $cat) {
        if ($key !== 0) {
            echo "-";
        }       
        echo '<a href="' . get_category_link( $cat->category_parent ) .'"> ' . $cat->name . '</a>';

    }
}

Answer 1

foreach ($child as $cat) {
    if ($key !== 0) {
        echo "-";
    }       
    echo '<a href="' . get_category_link( $cat->category_parent ) .'"> ' . $cat->name . '</a>';
}

应该是

foreach ($child as $key => $cat) {
    if ($key !== 0) {
        echo "-";
    }       
    echo '<a href="' . get_category_link( $cat->category_parent ) .'"> ' . $cat->name . '</a>';
}

WordPress子类别不显示
