WP_Query头痛 [英] WP_Query headache

问题描述

我正在尝试使用WP_Query输出带有标签的最新3篇帖子.我在stackoverflow上问过这个问题，并从一个好心人那里得到了很好的建议.这就是我现在拥有的:

I am trying to use WP_Query to output the 3 latest posts with the tag featured. I asked about it here on stackoverflow and got at good tip from a kind person. This is what I have now:

<?php

$home_featured = new WP_Query(array(
    'tag' => 'featured',
    'posts_per_page' => 3,
));

?>

<?php if ($home_featured->have_posts()): while ($home_featured->have_posts()) : $home_featured->the_post(); ?>

    <p>Got some</p>

<?php endwhile; ?>

<?php else: ?>

    <p>None found</p>

<?php endif; ?>

现在，我有3篇带有标签的帖子.由于Wordpress在此处使用while循环，因此每个帖子最多应执行一次迭代，最多3次，输出

Got some

Now, I have 3 posts that have the tag featured. Since Wordpress uses a while loop here, it should do one iteration per post up to 3 times, outputting a

Got some

有一些 得到一些 有一些

Got some Got some Got some

但是它只输出一次，就像这样:

But it only outputs it one time, like this:

有一些

怎么了?

推荐答案

首先，将<p>Got some</p>替换为<?php the_title(); ?>.至少您会看到正在显示哪些帖子.

First thing, replace <p>Got some</p> by <?php the_title(); ?>. At least you'll see what posts are being shown.

您也可以在开始wordpress循环之前执行print_r( $home_featured );.您将获得传递给WP_Query的所有参数，为查询生成的SQL以及已返回的所有帖子.

You could also do a print_r( $home_featured ); just before starting the wordpress loop. You'll get all the parameters passed to WP_Query, the SQL generated for the query and all the posts that have been returned.

显示$home_featured->found_posts还将显示与当前查询参数匹配的帖子总数，从而为您提供帮助.

Echoing $home_featured->found_posts will also help you by displaying the total number of posts found matching the current query parameters.
