当上面的wordpress代码调试成立时，我收到此通知：注意：未定义的变量：在第50行的C：.... php中发布注意：尝试在第50行的C：.... php中获取非对象的属性

第50行是：$ terms = get_the_terms（$ post-＆gt; ID，'tagportfolio'）;

请帮我解决这个问题并解除通知？

Answer 1

删除该行$post = '';

$post是global变量。

然后您尝试访问$post属性

$terms = get_the_terms($post->ID, 'tagportfolio' );

这就是为什么你得到未定义的变量：在C：中发布

Answer 2

您可以尝试以下方式，

就是这样：

global $wp_query;
$post = $wp_query->post;

WordPress注意：未定义的变量：在C中发布：
