我试图循环思考一个自定义的帖子类型(艺术家),然后是每个类别,然后是另一个与艺术家有关系的自定义帖子类型(故事)。
问题是,最后一个循环中的函数<?php echo get_the_title( $story->ID ); ?>
多次返回艺术家的标题,以及当前自定义帖子的标题。我只需要当前循环帖子的标题。
<!-- get all the artists -->
<?php
$args = array(
'post_type' => 'artists'
);
$query = new WP_QUERY( $args );
?>
<?php if( $query->have_posts() ) : while( $query->have_posts() ) : $query->the_post(); ?>
<h1><?php the_title(); ?></h1>
<p><?php the_field('artist_website'); ?></p>
<!-- looping through all the categories -->
<?php
$cats = get_categories();
// loop through the categries
foreach ($cats as $cat) {
// setup the cateogory ID
$cat_id= $cat->term_id;
// Make a header for the cateogry
echo "<h2>".$cat->name."</h2>";
?>
<!-- looping through the stories that have a relationship with the artist (select_artist) -->
<?php
$post_type = 'story';
$args = array(
'post_type' => $post_type,
'posts_per_page' => -1, //show all posts
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => $cat->slug,
)
),
'meta_query' => array(
array(
'key' => 'select_artist', // name of custom field
'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123.
'compare' => 'LIKE'
)
)
);
$stories = new WP_Query($args);
?>
<?php if( $stories ): ?>
<ul>
<?php foreach( $stories as $story ): ?>
<!-- Problem echo below -->
<?php echo get_the_title( $story->ID ); ?>
<?php endforeach; ?>
</ul>
<?php endif; ?>
<?php } // done the foreach statement ?>
<?php endwhile; wp_reset_postdata(); endif; ?>
</section>
如果使用WP_Query,则应该使用while循环并以_post()结束,以便设置允许get_the_title()正常工作的内部变量。
作为一个额外的度量,您可以在内部循环之前将$post变量设置为$temp变量,然后在内部循环之后重置。
<?php
$stories = new WP_Query($args);
if( $stories->have_posts() ):
global $post;
$temp = $post;
?>
<ul>
<?php
while( $stories->have_posts() ): $stories->the_post();
the_title();
endwhile;
$post = $temp;
?>
<ul>
<?php endif; ?>
