我的WP\\u查询有点困难，其中包括一个meta\\u查询，用于根据ACF用户字段限制帖子，但如果用户可以“编辑\\u帖子”，则显示所有帖子。从下面的代码中可以看出，前两个数组在以下位置工作良好：；

在ACF字段中选择当前用户ID；或ACF用户字段为空，因此值为“”；或当前用户功能为“编辑帖子”如果存在这三种情况中的任何一种，则相应地显示帖子。这是第三种情况，它不起作用，需要一些帮助。这是我目前的代码：

    $user_exception = current_user_can(\'edit_posts\');
    $current_user_id = get_current_user_id();
    $query = new WP_Query( array(
        \'post_type\' => \'promotions\',
        \'posts_per_page\' => 10,
        \'meta_key\'          => \'promo_start_date\',
        \'orderby\'           => \'meta_value_num\',
        \'order\'             => \'DESC\',
        \'paged\' => $paged,
        \'meta_query\'     => array(
            \'relation\'      => \'OR\',
            array(
                \'key\'     => \'dedicated_promotion\',
                \'value\'   => $current_user_id,
                \'compare\' => \'LIKE\'
            ),
            array(
                \'key\'     => \'dedicated_promotion\',
                \'value\'   => \'\',
                \'compare\' => \'=\'
            ),
            array(
                \'key\' => \'wp_capabilities\', //This part is current not working as I intended 
                \'value\' => $user_exception,
                \'compare\' => \'=\'
            )
        )
    ) );
?>

有人对如何检索当前登录的用户功能并将其添加到meta\\u查询中有什么建议吗？

<?php
//create variables
$paged = ( get_query_var( \'paged\' ) ) ? get_query_var( \'paged\' ) : 1;
$current_user_id = get_current_user_id();
//check if current user is a subscriber and define meta_query arguments

$args = array(
    \'post_type\' => \'promotions\',
    \'posts_per_page\' => 10,
    \'meta_key\'          => \'promo_start_date\',
    \'orderby\'           => \'meta_value_num\',
    \'order\'             => \'DESC\',
    \'paged\' => $paged
);

if (current_user_can( \'subscriber\' )) {
    // Add meta_query
    $args[\'meta_query\'] = array(
        \'relation\'      => \'OR\',
        array(
            \'key\'     => \'dedicated_promotion\',
            \'value\'   => $current_user_id,
            \'compare\' => \'LIKE\'
        ),
        array(
            \'key\'     => \'dedicated_promotion\',
            \'value\'   => \'\',
            \'compare\' => \'=\'
        )
      );
}

//set up the query
$query = new WP_Query($args);
if ( $query->have_posts() ) : ?>
