编辑：我有一个自定义帖子类型的存档页面。此页面上显示的每篇文章都有通过高级自定义字段输入的关于该文章的信息，以及打开模式窗口的按钮（隐藏在循环中的div，用于打开php mailer表单）。在该模式窗口中，有一个下拉列表。
作为选项填充自定义帖子类型标题的下拉列表。它使用WP查询从Wordpress中提取这些标题。
CPT详细信息部分和模式打开按钮的代码
<div class="property-details">
<h2><?php the_title(); ?></h2>
<?php echo get_field(\'property_address\');?>
<!-- excerpt -->
<?php if( \'\' != get_the_excerpt() || \'\' != get_the_content() ) { ?>
<?php do_action(\'layers_before_list_post_content\'); ?>
<?php do_action(\'layers_list_post_content\'); ?>
<?php do_action(\'layers_after_list_post_content\'); ?>
<?php } ?>
</div>
<a href="#open-modal-form-<?php echo $post->ID; ?>" class="button inquire-button">Inquiry</a>
模态部分代码：
<div id="open-modal-form-<?php echo $post->ID; ?>" class="modal-window">
<div>
<a href="#" title="close" class="modal-close"><i class="eicon-close"></i></a>
<!-- I couldn\'t get contact form 7 to play nice, so I made my own form. Recipient Email is managed in inquiry.php. -->
<form action="<?php bloginfo(\'template_directory\'); ?>/inquiry.php" method="post">
<input type="text" name="fname" placeholder="First name">
<input type="text" name="lname" placeholder="Last name">
<?php
$args = array(
\'post_type\' => \'property\',
\'tax_query\' => array(
array(
\'taxonomy\' =>\'project_category\',
\'field\' => \'slug\',
\'terms\' => array(\'current-projects\',\'past-projects\')
)
),
);
$the_query = new WP_Query($args);
?>
<select name="propname">
<?php
if($the_query->have_posts()){
while($the_query->have_posts()) : $the_query->the_post(); ?>
<option><?php the_title(); ?></option>
<?php endwhile;
} wp_reset_query();
?>
</select>
<input type="email" name="email" placeholder="Email">

<input type="submit" value="Send Request">

我如何才能在我当前所在的页面上（下拉列表中有一个CPT模式窗口）选择下拉列表中的一个？

（修改后的答案）
如果我理解正确，请尝试以下方法：
定义$the_post 对于每个“属性”：
<?php $the_post = get_post(); ?>
<div class="property-details">
<h2><?php the_title(); ?></h2>
...
</div>
<select name="propname">
<?php
$found = wp_list_filter( $the_query->posts, [ \'ID\' => $the_post->ID ] );
if ( empty( $found ) ) :
?>
<option selected><?php echo get_the_title( $the_post ); ?></option>
<?php
endif;
if($the_query->have_posts()){
while($the_query->have_posts()) : $the_query->the_post(); ?>
<option<?php selected( get_the_ID(), $the_post->ID ); ?>><?php the_title(); ?></option>
<?php endwhile;
} wp_reset_query();
?>
</select>
