我试图通过写这篇文章的作者的头像。我认为这会使这项工作有效，但它似乎没有输出正确的 url 并在图像上给我一个 404。

其他人用什么方法拉过头像？

我正在寻找一个答案，告诉我如何做到这一点，如果没有不显示的图像。

更新：

我已经尝试使用以下代码来完成这项工作：我应该提到我也在尝试在我的本地机器上进行这项工作。

echo get_avatar($authorId, 100); 

（变量使用get_the_author_id()）

Answer 1

<?php echo get_avatar( $id_or_email, $size, $default, $alt, $args ); ?> 

哪里id_or_email需要。这在您的代码中缺失。更多https://codex.wordpress.org/Function_Reference/get_avatar

所以在你的代码中，尝试获取作者图片：

<?php echo get_avatar( get_the_author_meta( 'ID' ), 32 ); ?>

Answer 2

您需要为“id_or_email”添加参数以获取适当的头像。对于 WordPress 2.7 或更低版本，您可以使用 get_the_author_id()。对于 WordPress 2.8 及更高版本，您可以使用 get_the_author_meta('ID')。该函数返回字符串或 false 布尔值。您可以通过比较返回值来判断您是否有头像。-获取头像
