Timber Twig：按类别查询自定义 Post 类型并输出帖子的简码

Question

我想做的是生成一个名为 report 的新自定义 Post 类型，添加分类法，查询报告，然后生成 [=15] 格式的简码=] 以显示常规类别中的报告。

现在，在 report/index.twig，我得到了使用简码 [report_listing] 的所有报告的列表，以及使用 [report_listing category="general"].[=25 时的错误 No reports available =]

我正在使用高级自定义字段，但这似乎不是本网站或网站其他部分的问题。类别正在生成并与 post 相关联，因为这是使用 [report_listing] 时一份报告在 /index.twig 上的示例 {{ dump }} 输出，并且显示所有报告：

["report_category"]=> array(1) { [0]=> object(Timber\Term)#2131 (15)
{ ["PostClass"]=> string(11) "Timber\Post" ["TermClass"]=> string(4) "Term"
["object_type"]=> string(4) "term" ["_children"]=> NULL ["name"]=> string(7)
"General" ["taxonomy"]=> string(15) "report_category" ["id"]=> int(89) ["ID"]=> int(89)
["term_id"]=> int(89) ["slug"]=> string(7) "general" ["term_group"]=> int(0)
["term_taxonomy_id"]=> int(89) ["parent"]=> int(0) ["count"]=> int(0) ["filter"]=> string(3) "raw" } }

我查看了，但我使用的是 tax_query 参数。调试日志中没有 php 错误。

index.twig 上的循环：

{% if reports %}

    {% for report in reports %}

        (html)

    {% endfor %}

    {% else %}

        No reports available.

{% endif %}

插件中生成自定义 post 类型和短代码的完整代码：

    register_post_type('report',

通过阅读您当前的问题和代码，我可以看出一些问题。但我想解决短代码功能，我认为这是导致报告未按类别列出的原因。

// Query all reports and create shortcode

function report_get_listing($params) {
    $reports = [];

   $a = shortcode_atts( array(
    'category' => '', // [report_listing category=""]
   ), $params );

    $context = Timber::get_context();

    $args = array(
        'post_type' => 'report',
        'orderby' => [
            'weight' => 'ASC',
            'post_date' => 'DESC'
        ],
        'post_status' => 'publish',
        'meta_query' => [
            'weight' => [
                'key'     => 'weight',
                'compare' => 'EXISTS',
                'type'    => 'NUMERIC'
            ],

        ],
    );


  // Check for a report category in the query

  if (!empty($a['category'])) {
        $args['tax_query'] = array(
            array(
                'taxonomy' => 'report_category',
                'terms' => explode(',', $a['category']),
                'field' => 'slug',
                'operator' => 'IN',
            ),
        );
    }

    query_posts($args);

    $report_listing = Timber::get_posts($args);

    foreach ($report_listing as $p) {
        $reports[] = get_single_report($p);
    }

    $context['reports'] = $reports;

    return Timber::compile('report/index.twig', $context);
}

add_shortcode('report_listing', 'report_get_listing');

这个问题原来是一个奇怪的插件冲突:( 。我发现使用查询监视器。我问题中的上述示例代码工作正常。
