好吧，这真的很奇怪。我不认为自己是WordPress专家，但我也不是初学者。我创建了一个模板，它可以按照我需要的方式工作。基本上，它会检查与页面关联的附件，并将其显示在图库中。

当没有父级时，此模板工作正常。然而，当它变成一个孩子时，它就破碎了。它恢复到静态主页，页面标题变为（空格）-（站点名称），这向我表明WordPress对它是什么类型的页面感到困惑。

以下是完整的模板页面：

<?php

/*

Template Name: Gallery

*/

wp_register_script( \'script\', get_template_directory_uri() . \'/js/product-script.js\' );
wp_register_script( \'jPages\', get_template_directory_uri() . \'/js/jPages.js\' );
wp_enqueue_script( \'jPages\');
wp_enqueue_script( \'script\' );

get_header(); 

global $post;

$querystr = \'SELECT \' . $wpdb->prefix . \'posts.post_title AS "imageTitle", \' . $wpdb->prefix . \'posts.post_content AS "imageDescription", \' . $wpdb->prefix . \'posts.guid AS "imageGuid" FROM \' . $wpdb->prefix . \'posts WHERE \' . $wpdb->prefix . \'posts.post_parent = \'. $post->ID .\' AND \' . $wpdb->prefix . \'posts.post_type = "attachment" ORDER BY post_title  LIMIT 1\';

global $wpdb;

$post_item = $wpdb->get_row($querystr);

$first_title = $post_item->imageTitle;
$first_attachment = $post_item->imageGuid;
$first_description = $post_item->imageDescription;


$args = array( \'post_type\' => \'attachment\', \'numberposts\' => -1, \'post_status\' => null, \'post_parent\' => $post->ID, \'order\' => \'ASC\', \'orderby\' => \'title\' );

$attachments = get_posts($args);

if ($attachments) { 

?>

<div class="container clearfix">

<span id="gallery-page" class="clearfix"><?php echo the_title(); ?></span>
<div class="img clearfix">

    <?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>

    <div class="col-three">

        <div id="gallery-thumbs">

            <ul class="thumbs noscript clearfix" id="gallery-ul">

                <?php


                foreach ( $attachments as $attachment ) {

                    $title = apply_filters( \'the_title\' , $attachment->post_title );

                    $full_src = wp_get_attachment_image_src( $attachment->ID, \'full\' );

                    $thumb_src = wp_get_attachment_image_src( $attachment->ID, array( 100, 100) );

                    $description = $attachment->post_content;

                    $description = str_replace(\'*\', \'<br />\', $description);
                    $first_description = str_replace(\'*\', \'<br />\', $first_description);


                    if ( get_post_meta($attachment->ID, \'new\', true))
                    {
                        $new = \'<span>New!</span>\';
                    }

                    $ul = \'<ul><li>\';
                    $end_ul = \'</li></ul>\';


                    ?>

                    <li>


                        <a class="thumb " href="<?php echo $full_src[0]; ?>" title="<?php echo $title; ?>" rel="<?php echo $full_src[0]; ?>" >

                            <img src="<?php echo $thumb_src[0]; ?>" alt="<?php echo $title; ?>" class="clearfix gallery-imgs"  /><br />
                            <?php echo $new; echo mb_strimwidth($title, 0, 14, \'...\'); ?>
                            <div class="desc-swap" style="display:none;"><?php echo $description; ?></div>
                            <div class="title-swap" style="display:none;"><?php  echo $title; ?></div>
                            <div class="new" style="display:none;"><?php echo $new; ?></div>

                        </a>

                    </li>

                    <?php
                    unset($new);

                }

                ?>

            </ul>
            <div class="holder"></div>

        </div>

        echo \'</div><!--.title-container-->\';

        echo \'<img id="mainpic" src="\'.$first_attachment.\'" width="480" />\';

        echo \'<section id="description-container">\';

        echo \'<span class="new-destination" id="description-new"></span><br />\';

        echo \'<section class="desc-destination">\'.$first_description.\'</section>\';

        echo \'</section<!--description-container-->\';

        ?>

    </div>

</div>

</div>
<?php

endwhile; endif;

}
?>
<section id="modal-menu">
<?php require (\'modal-menu.php\');?>
</section><!--#modal-menu-->
<?php
get_footer();

?> 

考虑到代码中的某些内容可能会破坏它，我已经尝试删除初始查询和最后的模态部分，但没有任何效果。通常我会自己寻找答案。。。但在这种情况下，我完全不知道从哪里开始。

谢谢你的帮助！
