我用的是buddypress主题buddyboss. 主要原因是这个主题能够管理一个图片库（效果很好）。

现在我想在members循环中调用picture函数。buddyboss的一位管理员告诉我：

“您需要buddy\\u boss\\u pics.php中的函数。具体来说，您需要从第285行开始使用函数buddyboss\\u pics\\u screen\\u picture\\u grid\\u content（）。您需要编辑文件以使用members循环，因为它当前使用的是displayed\\u user\\u id。”

函数的外观如下：

function buddyboss_pics_screen_picture_grid_content()
{
    global $bp, $wpdb, $bbpics;

    $wpdb->show_errors = BUDDY_BOSS_DEBUG;

    $img_size = is_active_sidebar( \'Profile\' ) ? \'buddyboss_pic_med\' : \'buddyboss_pic_wide\';

    $gallery_class = is_active_sidebar( \'Profile\' ) ? \'gallery has-sidebar\' : \'gallery\';

    $user_id = $bp->displayed_user->id;
    $activity_table = $wpdb->prefix."bp_activity";
    $activity_meta_table = $wpdb->prefix."bp_activity_meta";

    $pages_sql = "SELECT COUNT(*) FROM $activity_table a INNER JOIN $activity_meta_table am ON a.id = am.activity_id WHERE a.user_id = $user_id AND meta_key = \'bboss_pics_aid\'";

    $bbpics->grid_num_pics = $wpdb->get_var($pages_sql);

    $bbpics->grid_current_page = isset( $_GET[\'page\'] ) ? (int) $_GET[\'page\'] : 1;

    // Prepare a SQL query to retrieve the activity posts 
    // that have pictures associated with them
    $sql = "SELECT a.*, am.meta_value FROM $activity_table a INNER JOIN $activity_meta_table am ON a.id = am.activity_id WHERE a.user_id = $user_id AND meta_key = \'bboss_pics_aid\' ORDER BY a.date_recorded DESC";

    buddy_boss_log("SQL: $sql");

    $pics  = $wpdb->get_results($sql,ARRAY_A);

    $bbpics->grid_pagination = new BuddyBoss_Paginated( $pics, $bbpics->grid_pics_per_page, $bbpics->grid_current_page );

    buddy_boss_log("RESULT: $pics");

    // If we have results let\'s print out a simple grid
    if ( !empty( $pics ) )
    {
        $bbpics->grid_had_pics = true;
        $bbpics->grid_num_pics = count( $pics );
