我真的希望你能在这里帮忙。
我正在为客户创建一个主题，并且我创建了一个名为“Testimonials”的自定义帖子类型，现在我想在主页上显示推荐，但是我无法输出元信息的数据
我在我的functions.php文件中创建了一个名为'show_testimonials'的函数，我在我的index.php文件中调用了这个函数（我还没有将所有内容分成它们的组成部分，例如header.php，footer .php等）。此功能旨在显示“推荐书”自定义帖子类型中的帖子和元信息，但它不会。
我可以看到我正在将正确的元数据提取到我的'$ meta'变量中。
以下是'show_testimonials'功能的代码。
function show_testimonials() {
$loop = new WP_Query(
array(
'post_type' => 'shv_testimonials',
'order_by' => 'ID',
)
);
if ($loop->have_posts()) {
$output = '<ul class="testimonial-list">';
while($loop->have_posts()) {
$loop->the_post();
$meta = get_post_meta(get_the_id(), '');
print_r($meta);
$output .= '
<li>
<a href="' . get_permalink() . '">
' . get_the_title() . ' | ' .
$meta['shv_testimonial_author'][0] . '
</a>
</li>
';
}
}
return $output;
}
下面是我的index.php文件。

这是开发网站的链接，您可以在其中看到我使用'print_r（$ meta）;'输出正确的元数据。 http://dev.garethdaine.com/shiverschool
我希望有人能指出我正确的方向。提前干杯。

show_testimonials的输出不会在任何地方打印，请在您的模板中尝试echo show_testimonials()，或在echo $output;函数中使用return $output;代替show_testimonials。
