答案 0 :(得分:4)
在尝试使用之前,您不会包含全局帖子。引起问题的线是:
$portfolio_large = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'portfolio-large' );
$portfolio_thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'portfolio-image' );
此特定错误有两种解决方案。
1)
将global $post;
添加到您的函数顶部。 E.g。
function portfolio_shortcode( $atts, $content = null ) {
global $post;
...
2)
您已使用$idd = get_the_ID();
获取ID。使用它而不是$post->ID
。 E.g。
$portfolio_large = wp_get_attachment_image_src( get_post_thumbnail_id( $idd ), 'portfolio-large' );
$portfolio_thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $idd ), 'portfolio-image' );
还有第三种选择,我最后会提到它,因为如果你将来遇到类似的问题,它对你没有帮助。 get_post_thumbnail_id()
将对循环中的当前帖子起作用。因此,您无需传入任何ID。
