wordpress - WordPress 中的 Alt 属性为空

Question

我的代码

<?php echo the_post_thumbnail( 'thumbnail' ); ?>

退货：像这样

<img width="650" height="366" src="https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-650x366.jpg" class="attachment-thumbnail size-thumbnail wp-post-image" alt="" srcset="https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-650x366.jpg 650w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-300x169.jpg 300w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-768x432.jpg 768w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-1024x576.jpg 1024w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-255x143.jpg 255w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112-1110x623.jpg 1110w, https://test.com/wp-content/uploads/2019/02/5c1c7adb0c92110fd79f66aa_1545370331112.jpg 1500w" sizes="(max-width: 650px) 100vw, 650px">

这里的alt属性值为空。

但我需要为该alt物业填写一些内容以修复 SEO 错误。

提前致谢。

默认情况下，wordpress 正在从“媒体”模块获取上传的图片替代（替代）内容。

例子，

如果图像源包含替代内容，则“the_post_thumbnail('thumbnail')”将返回 DOM 中的替代文本。
