我正在尝试为自定义帖子类型创建一个循环，首先计算它包含多少帖子。如果它只包含一篇文章，它应该只显示文章的内容区域。如果帖子包含多篇帖子，则应显示循环中所有帖子的摘录。有人发现了吗？

found_posts 是查询返回的帖子总数。示例代码：
<?php
$args = array( \'post_type\' => \'your_custom\' );
$custom_query = new WP_Query( $args );
if( $custom_query->have_posts() ) {
$number_of_posts = $custom_query->found_posts;
while( $custom_query->have_posts() ) {
$custom_query->the_post();
if( $number_of_posts == 1 ) {
the_content();
} else {
the_excerpt();
}
}
wp_reset_postdata();
}
?>

请尝试此代码（&P）；让我知道结果（我还没有测试）
<?php
$post_query = new WP_Query(\'post_type=post\'); // replace the post type with your post type key
$total_posts_found = $post_query->found_posts;
if($total_posts_found < 2 && $total_posts_found > 0){
if($post_query->have_posts()) : while($post_query->have_posts()) : $post_query->the_post();
echo \'<h1>\'get_the_title().\'</h1>\';
echo get_the_content();
endwhile;
endif;
wp_reset_postdata();
} else {
if($post_query->have_posts()) : while($post_query->have_posts()) : $post_query->the_post();
echo \'<h1>\'get_the_title().\'</h1>\';
echo get_the_excerpt();
endwhile;
endif;
wp_reset_postdata();
}
?>
