Question

我正在尝试找到问题的解决方案，但找不到任何有用的东西。我需要获取此查询创建的“距离”变量以及所有其他数据（用户，userData，商品等）。对于我拍摄的每张唱片，我需要在视图中打印“km”的距离。

以下是代码：

if(property_exists($params, "lat") && property_exists($params, "lng")) {
    if(null == $params->lat || null == $params->lng) {
        //don't use coordinates
    } else {
        $radius = $this->coordMaxRadius;
        $query->whereHas("userData", function($q) use ($params, $radius) {
            $q->selectRaw( \DB::raw("
            ROUND( 6371 * acos( cos( radians($params->lat) ) 
              * cos( radians( lat ) ) 
              * cos( radians( lng ) - radians($params->lng) ) 
              + sin( radians($params->lat) ) 
              * sin( radians( lat ) ) ) ) AS distance "));
            $q->having("distance", "<", $radius)->orderBy("distance");
        });
    }
} 
/***** later in the code *****/
$query->with("timeSlots.days", "timeSlots.time", "userData", 
             "university", "faculty", "user", 'userData.feedbacks');

我也在几周之前处理同样的问题。我有解决方案，但我知道完全正确与否

#If the list color has at least one color in it (E.g)color = ['blue','white','maladroit']
    print('Nothing to see here')

#If the list only consists of elements that aren't colors 
#(E.g)color = ['hurley','maladroit']
    print("I don't see colors.... I actually legit don't...")

Eloquent：需要从此查询中返回“距离”（坐标）
