视频学习参考: https://www.youtube.com/watch?v=e8nJMopiH2Q&list=PLriKzYyLb28nUFbe0Y9d-19uVkOnhYxFE&index=10
本节课的重点函数是 get_categories();
$args_cat = array( ‘include’ => ‘1, 9 ,8’);
$categories = get_categories($args_cat);
foreach($categories as $category):
$args = array(
'type' => 'post',
'posts_per_pages' => 1,
'offset' => 0,
//'category__in' => array(),
//'category__not_in' => array(),
'category__in' => array($category->term_id),
);
$lastBlog = new WP_Query($args);
if ( $lastBlog -> have_posts() ) :
while ( $lastBlog -> have_posts() ) :
$lastBlog -> the_post();
the_title();
endwhile;
endif;
endforeach;
** 当一篇文章选择归属于2个分类时 会同时属于2个分类
Super happy!
