长话短说。我正在尝试扩展投资组合模板的功能。它目前只能处理一页。我可以复制模板，依靠自定义字段来拉入特定的 portfilio 项目（主题使用自定义帖子类型）。

所以，这是我的portfolio-template.php中的一点：

   $args = array(
          'post_type' => 'portfolio',
        'orderby' => 'menu_order',
        'order' => 'ASC',
        'meta_value' => 'ao',
        'posts_per_page' => -1
    );

所以，我想创建一个新页面，选择投资组合模板，然后在该页面上定义一个自定义字段，将 meta_value 传递给投资组合模板.php

所以它看起来像这样：

    $args = array(
        'post_type' => 'portfolio',
        'orderby' => 'menu_order',
        'order' => 'ASC',
        'meta_value' => 'PULL_VALUE_FROM_CUSTOM_FIELD',
        'posts_per_page' => -1
    );

“PULL_VALUE_FROM_CUSTOM_FIELD”是我无法弄清楚的一点。对不起，如果我的白话是code_crude，我是新手！

在循环之前，您可以访问全局变量$post，如果是single.php并且page.php将表示将由模板文件显示的帖子类型（post/page/cpt）对象。

如果没记错的话，category.php例如在 中使用时，它会抓取第一个。

因此，在有问题的情况下：

<?php
global $post;
$the_meta = get_post_meta( 'custom_field_name', $post->ID );

if( !$the_meta )
    $the_meta = 'your_backup_solution';

$args = array(
    'post_type'      => 'portfolio',
    'orderby'        => 'menu_order',
    'order'          => 'ASC',
    'meta_value'     => $the_meta,
    'posts_per_page' => -1
);

$portfolio_query = new WP_Query($args);
// et cetera
