我目前正在学习WordPress插件开发，我正在尝试为我的插件构建一个简短的代码 我的插件基本上是一个名为property的自定义帖子类型，里面有3个元数据框 价格位置和建设日期 和一种称为财产类型的分类，在后端设置租金或销售 所有这一切都有效，如果你把它们放在wordpress中，它们就会起作用 但我的短代码文件确实正常工作WP_Query上的循环应该返回我所做的所有帖子，但它只返回WP_Query中找到的第一个元素
任何人都可以指导我或修复我错误的地方
感谢所有
现在我的短代码文件名是：properties_post_type_shortcode.php
我的插件文件名是：properties_post_type.php
properties_post_type_shortcode.php的代码
<?php
add_shortcode('land_properties',function(){
$loop = new WP_Query(
array(
'post_type' => 'property_post',
'orderby' => 'title'
)
);
if ($loop->have_posts()){
$output = '<ul class="land_properties_list">';
$i=0;
while( $loop->have_posts() ){
$loop->the_post();
$meta=get_post_meta(get_the_id(),'' );
$output= '
<li>
<a href="' .get_permalink() . '">
' . get_the_title() . ' | '.
$meta['property_price'][0]. " " .
$meta['property_location'][0]. " " .
$meta['property_date'][0]. " " .
'
</a>
<div>' . get_the_excerpt() . '</div>
</li>
';
}
}
else {
$output="No lands added";
}
// $loop->wp_reset_postdata();
return $output;
});

要查询所有帖子，请将以下内容添加到WP_Query：
'posts_per_page' => -1
您的代码：
$loop = new WP_Query( array(
'post_type' => 'property_post',
'orderby' => 'title',
'posts_per_page' => -1
) );
