我正在尝试通过WP_Query获取帖子内容, 我有:
function my_query( $attributes ) {
$args = array(
'post_type' => 'post', 'posts_per_page' => 3, 'post_status' => 'publish'
);
$query = new WP_Query($args);
$posts = '';
if($query->have_posts()) {
$posts .= '<div class="post-wrapper">';
while ($query->have_posts()) {
$query->the_post();
$posts .= '<div class="img-container">';
$posts .= '<div>' . get_the_post_thumbnail() . '</div>';
$posts .= '</div>';
$posts .= '<div class="content-container">';
$posts .= '<span>' . get_the_title() . '</span>';
$posts .= '</div>';
}
$posts .= '</div>';
wp_reset_postdata();
return $posts;
}
它正在工作, 我在html中输入如下内容:
<div class="post-wrapper">
<div class="img-container">
<div><img src="..." alt=""></div>
</div>
<div class="content-container">
<span>some title</span>
</div>
</div>
<div class="post-wrapper">
<div class="img-container">
<div><img src="..." alt=""></div>
</div>
<div class="content-container">
<span>some title</span>
</div>
</div>
<div class="post-wrapper">
<div class="img-container">
<div><img src="..." alt=""></div>
</div>
<div class="content-container">
<span>some title</span>
</div>
</div>
但是我需要像这样划分容器图像和标题:
<div class="post-wrapper">
<div class="img-container">
<div><img src="..." alt=""></div>
<div><img src="..." alt=""></div>
<div><img src="..." alt=""></div>
</div>
<div class="content-container">
<span>some title</span>
<span>some title</span>
<span>some title</span>
</div>
</div>
如何正确执行此操作?
你能帮我吗?提前致谢。

我会主张使用Output Buffering, 但是我认为目前一种更简单的解决方案是构建多个变量, 而不是仅一个$ posts变量, 而无需太多更改代码结构(并且无需依赖多次遍历posts)。然后在while循环之后合并它们。像这样:
$args = array(
'post_type' => 'post', 'posts_per_page' => 3, 'post_status' => 'publish'
);
$query = new WP_Query( $args );
$container = $images = $titles = ''; // Start with 3 variables
if( $query->have_posts() ){
// Start the $container;
$container .= '<div class="post-wrapper">';
// Build the $images and $titles separately;
while( $query->have_posts() ){
$query->the_post();
$images .= '<div class="img-container">';
$images .= '<div>' . get_the_post_thumbnail() . '</div>';
$images .= '</div>';
$titles .= '<div class="content-container">';
$titles .= '<span>' . get_the_title() . '</span>';
$titles .= '</div>';
}
// Now that $images and $titles are build, add them to the $container;
$container .= $images;
$container .= $titles;
// Now close the container
$container .= '</div>';
wp_reset_postdata();
return $container;
}

假设循环中没有更多帖子, 则可以多次调用have_posts。它将倒退到开始。
function my_query( $attributes ) {
$args = array(
'post_type' => 'post', 'posts_per_page' => 3, 'post_status' => 'publish'
);
$query = new \WP_Query($args);
$posts = '';
if($query->have_posts()) {
$posts .= '<div class="post-wrapper"><div class="img-container">';
while ($query->have_posts()) {
$query->the_post();
$posts .= '<div>' . get_the_post_thumbnail() . '</div>';
}
$posts .= '</div><div class="content-container">';
while ($query->have_posts()) {
$query->the_post();
$posts .= '<span>' . get_the_title() . '</span>';
}
$posts .= '</div></div>';
wp_reset_postdata();
return $posts;
}
}
}
