我最终接受了西蒙·斯卡夫的建议get_template_part.

为了防止任何人需要它，此页面（正在进行的工作）创建一个高级搜索表单，然后构建一个WP\\U查询来搜索自定义帖子类型：

<?php if (isset($_POST["act"]) && $_POST["act"] == "s") : ?>

<?php
    $meta_query = array(\'relation\' => \'AND\');

    if (!empty($_POST["s_genus"])) {
        $genus = array(
            \'key\' => \'genus\',
            \'value\' => $_POST["s_genus"],
            \'compare\' => \'LIKE\'
        );
        $meta_query[] = $genus;
    }

    if (!empty($_POST["s_species"])) {
        $species = array(
            \'key\' => \'species\',
            \'value\' => $_POST["s_species"],
            \'compare\' => \'LIKE\'
        );
        $meta_query[] = $species;
    }

    $args = array(
        \'post_type\' => \'species\',
        \'meta_query\' => $meta_query
    );

    get_template_part(\'searchresults\');
?>

<?php else : ?>

    <div id="content">

    <p>Sorry, but you are looking for something that isn\'t here.</p>
