thumbnails - 获取帖子缩略图功能不起作用？

Question

我正在使用此功能获取子页面缩略图

 <a href="<?php echo get_page_link($page->ID) ?>" title="<?php echo $page->post_title ?>"><?php echo get_the_post_thumbnail($post->ID, 'thumbnail', 'alt="' . $page->post_title . '"'); ?></a>

请帮助我！

Answer 1

array在第三个参数中使用

<a href="<?php echo get_page_link($page->ID); ?>" title="<?php echo $page->post_title; ?>"><?php echo get_the_post_thumbnail($post->ID, 'thumbnail', array( 'alt' => $page->post_title , 'title' => $page->post_title ) ); ?></a>
