例: 菜单(父菜单) 清单1(儿童) 清单2(儿童) 清单3(儿童) 清单4(儿童) 清单5(儿童) 清单6(儿童) 清单7(儿童) 清单8(儿童)



您可以在get\u categories函数中使用user number=6,如

$talentChildren = get_categories(array('child_of' => get_category_by_slug('news')->term_id,'number' => 6,'hide_empty' => 0));
foreach($talentChildren as $talent):
    echo "<pre>";
    print_r($talent);
    echo "</pre>";
endforeach;
$talentChildren=get_categories(数组('child_of'=>get_categories_by_slug('news')->term_id,'number'=>6,'hide_empty'=>0));
foreach($talentChildren作为$talent):
回声“;
印刷(人才);
回声“;
endforeach;

$talentChildren = get_categories(array('child_of' => get_category_by_slug('news')->term_id,'number' => 6,'hide_empty' => 0));
foreach($talentChildren as $talent):
