需要一些PHP帮助来更改wordpress插件组吗

我在这里真的陷入困境。我非常接近启动我的wordpress网站。我有一个相当大的障碍在我的道路上，这应该是一个简单的解决办法。我是初级php，所以我在这方面真的很努力，任何帮助或指导都将非常感谢，因为我已经通过阅读和研究尝试解决这个问题两周了

这就是问题所在，我将尽量详细说明：

我有一个自定义的帖子类型叫做Portfolio

我有一个公文包页面，其中加载了 公文包发布到公文包页面上的网格中。你知道吗 基本的公文包设置，如果你点击它带你去的图片 公文包邮报

使用Groups插件，当我限制访问公文包帖子时， 它将从公文包页面网格中删除特征图像。像 非组成员的post不存在

我试图出售访问这些投资组合的职位，所以如果有人是 不是会员，他们不知道那里有什么东西可以买

我不知道如何才能在公文包页面上显示那些特色图片。我需要人们知道他们在那里，但不能访问他们。正如我在支持问题中提到的，我不能为此使用短代码，因为视频是硬编码到我的主题中的。我需要将其添加到自定义插件的代码中，以更改组，使其不从我的公文包页面中删除该特征图像，而不管帖子上的限制

add_filter( 'posts_where', array( __CLASS__, 'posts_where' ), 10, 2 );

     */
    public static function posts_where( $where, &$query ) {

        global $wpdb;

        $user_id = get_current_user_id();

        // this only applies to logged in users
        if ( $user_id ) {
            // if administrators can override access, don't filter
            if ( get_option( GROUPS_ADMINISTRATOR_ACCESS_OVERRIDE, GROUPS_ADMINISTRATOR_ACCESS_OVERRIDE_DEFAULT ) ) {
                if ( user_can( $user_id, 'administrator' ) ) {
                    return $where;
                }
            }
        }

        // 1. Get all the capabilities that the user has, including those that are inherited:
        $caps = array();
        if ( $user = new Groups_User( $user_id ) ) {
            $capabilities = $user->capabilities_deep;

                    $caps[] = "'". $capability . "'";
                }
            }
        }

        if ( count( $caps ) > 0 ) {
            $caps = implode( ',', $caps );
        } else {
            $caps = '\'\'';
        }

        // 2. Filter the posts that require a capability that the user doesn't
        // have, or in other words: exclude posts that the user must NOT access:

//          self::POSTMETA_PREFIX . self::READ_POST_CAPABILITY,
//          $caps
//      );

        // This allows the user to access posts where the posts are not restricted or where
        // the user has ANY of the capabilities:
        $where .= sprintf(
            " AND {$wpdb->posts}.ID IN " .
            " ( " .
            "   SELECT ID FROM $wpdb->posts WHERE ID NOT IN ( SELECT post_id FROM $wpdb->postmeta WHERE {$wpdb->postmeta}.meta_key = '%s' ) " . // posts without access restriction

            "   SELECT post_id AS ID FROM $wpdb->postmeta WHERE {$wpdb->postmeta}.meta_key = '%s' AND {$wpdb->postmeta}.meta_value IN (%s) " . // posts that require any capability the user has
            " ) ",
            self::POSTMETA_PREFIX . self::READ_POST_CAPABILITY,
            self::POSTMETA_PREFIX . self::READ_POST_CAPABILITY,
            $caps
        );

        return $where;
    }

add_filter( 'the_posts', array( __CLASS__, "the_posts" ), 1, 2 );

/**
     * Filter posts by access capability.
     * 
     * @param array $posts list of posts
     * @param WP_Query $query

    public static function the_posts( $posts, &$query ) {
        $result = array();
        $user_id = get_current_user_id();
        foreach ( $posts as $post ) {
            if ( self::user_can_read_post( $post->ID, $user_id ) ) {

            }
        }
        return $result;
    }

我浏览了一下，找到了控制进入受限岗位的部分。该类是组Post访问。当这两个都从class-groups-access.php中删除时，我可以看到公文包页面上的特色图片，但它也删除了限制实际帖子的功能。我不知道我怎么能告诉插件只返回特色图片，但仍然隐藏对帖子的访问

如果有人能通过为我的自定义帖子类型创建一个模板，让我更好地理解这里发生的事情，也许是他所指的一个例子，我会非常感激。非常感谢您抽出时间

这是通过使用wordpress来处理隐藏特定类别与更改实际插件代码来解决的。

为了提供帮助，我们需要知道：您尝试了什么，错误是什么。老实说，如果你向他们提供了你向我们提供的那么多信息，我并不奇怪他们会帮不上忙。。。插件论坛帖子的链接是什么？谢谢你的回复。我很确定他明白我说他是插件作者的意思。抱歉，有点模糊。我更新了这个问题以包含api中的代码。链接到。我用另一种方式问这个问题，因为有人问了一个类似的问题，他返回了与我相同的答案，没有关于如何进行更改的信息。这就是为什么我在这一页上这样问的原因。
