我的wordpress上有这个类别:

Test1
  - Sub1OfTest1
  - Sub2OfTest1
Test2
  - Sub1OfTest2
  - Sub2OfTest2

现在我在网址:http://localhost/wordpress/category/test1 我在文件category-test1.php

上写下以下代码
<?php
$categories =  get_categories('child_of=2');

print_r($categories);
foreach ($categories as $category) : ?>

        <div class="qitem">
            <a href="<?php get_category_link( $category->term_id ); ?>" title="<?php echo $category->name; ?>">
                <?php echo $category->name; ?>
            </a>
            <h4>
                <span class="caption">
                    <?php echo $category->name; ?>
                </span>
            </h4>
            <p>
                <span class="caption">
                    <?php echo $category->description; ?>
                </span>
            </p>
        </div>
<?php
endforeach;
?>

我正在尝试显示Test1的子类别,但代码只返回array()。我错过了什么?

该类别是空的吗?默认情况下,WordPress会隐藏emptr类别。尝试:

$categories =  get_categories('child_of=2&hide_empty=0');

编辑:已修复,谢谢@Stoep

child_of的{​​{1}}参数按其ID指定类别 - 假设您按顺序创建了类别,代码get_categories可能正在请求Sub1OfTest1的子类别。

要获取类别的ID,请转到帖子→类别,然后单击类别。 cat_ID将位于页面的URL中。

尝试这一点 - Show wordpress subcategories only

该主题也可能有所帮助,因为有不同的解决方案可以显示子类别。

//这是获取子类别和子子类别的编码     

    $args = array
    (
        'number'     => $number,
        'orderby'    => 'title',
        'order'      => 'ASC',
        'hide_empty' => false,
        'include'    => array(11,281,28,51,99,93,33,55,107,20),
        'exclude'    => array(32,29),
    );
    $product_categories = get_terms( 'product_cat', $args );
    // echo '<pre>';
    // print_r($product_categories);
    // echo '</pre>';

    foreach($product_categories as $data):
        if($data->slug = 'cooking')
        {
            $child_arg = array('hide_empty'=>false,'parent'=>$data->term_id,'exclude'=>array(32,29));
        }
        else
        {
            $child_arg = array('hide_empty'=>false,'parent'=>$data->term_id);
        }
        $child_terms = get_terms('product_cat',$child_arg);
        // echo "<pre>";
        // print_r($child_terms);
        // echo "</pre>";
        foreach($child_terms as $data1):
            if($data1->slug = 'cooking')
            {
                $sub_child_arg = array('hide_empty'=>false,'parent'=>$data1->term_id,'exclude'=>array(32,29));
            }
            else
            {
                $sub_child_arg = array('hide_empty'=>false,'parent'=>$data1->term_id);
            }
            $sub_child_terms = get_terms('product_cat',$sub_child_arg);
            // echo "<pre>";
            // print_r($sub_child_terms);
            // echo "</pre>";
        endforeach;
    endforeach;
