Question

我正在逐步解决（总是在你的帮助下）这个Eloquent查询，但还没有完全解决它。很抱歉仍然坚持下去，但我正在努力奋斗。

我已经用两种方式编写了查询。我想保留Laravel一个，因为我使用它，但它是一个不起作用的那个：

当我在PHPMYADMIN SQL WINDOW上做的时候工作：

select properties.id, title, city, price, postedat, propertytype,
( 3959 * acos( cos( radians(43) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-1.5) ) + sin( radians(43) ) * sin( radians( lat ) ) ) ) AS distance 
from properties
join addresses
on properties.id_address_fk = addresses.id
where city = 'Biarritz'
HAVING distance < 100
ORDER BY distance 
LIMIT 0, 20;

以下不工作（我得到了：试图从非对象错误中获取属性）

 $properties  = DB::table('properties')
        ->join('addresses', 'properties.id_address_fk', '=', 'addresses.id')
        ->select('properties.id', 'title', 'city', 'price', 'postedat', 'propertytype',
        DB::raw('3959 * acos( cos( radians(43) ) * cos( radians( lat ) ) * cos( radians(  lng ) -  radians  (-1.5) )+ sin( radians(43) ) * sin( radians( lat ) ) ) as distance') );


                if (!empty($location)) {
                $properties = $properties->where('location', '=', $location);
                }

                 if (!empty($propertytype)) {
                $properties = $properties->where('propertytype', '=', $propertytype);
                }

                 if (!empty($bedrooms)) {
                $properties = $properties->where('bedrooms', '>=', $bedrooms);
                }

                 if (!empty($transaction)) {
                $properties = $properties->where('transaction', '=', $transaction);
                }

                 if (!empty($minprice)) {
                $properties = $properties->where('price', '>=', $minprice);
                }

                 if (!empty($maxprice)) {
                $properties = $properties->where('price', '<=', $maxprice);
                }


                $properties->having('distance', '<', 100)
                ->orderBy('distance', 'desc')
                ->skip(0)
                ->take(5)
                ->get();
                        return View::make('propertyfound', compact('premium', 'properties'));

更新：

当然，错误是当它试图从非对象获取属性时

@foreach($properties as $propfound)

            <div class="row premium"> 
            <div class="col-sm-3 col-xs-3">
                <a href="{{URL::route('property', array($propfound->id) )}}" class="thumbnail " >{{ HTML::image("public/css/images/houses/$propfound->houses1")}}</a>
                <h5>Guide price: &pound; {{$propfound->price}}</h5>
                <h6>Bedrooms: {{$propfound->bedrooms}}</h6>
                <h6>Days on site: 4</h6>
                <h6>Sqft: {{$propfound->m2}}</h6>
            </div>   

            <div class="col-sm-9"> 
                <a href="{{URL::route('property', array($propfound->id))}}"><h3>{{$propfound->title}}</h3></a>
                <p>{{$propfound->description}}</p>
                <p class="hidden-xs"><a href="#">More details, 14 photos, floorplan and brochure</a> | <a href="#">Save property</a> | <a href="#">Contact agent</a> | <a href="#">Upgrade listing</a></p>
                <p class="hidden-xs">Marketed by Knight Frank, Richmond. Telephone: 0843 314 8224  <a href="#">BT 4p/min</a> </p>         
            </div>
            </div>
            <hr />      

            @endforeach

您不能简单地将 - ＆gt; get（）链接到原始数据库对象并获得结果。

// Doesn't work
$object->having()->take()->get();
foreach ( $object as $value ) {
    // $value is some part of the query builder/eloquent object 
}

您必须分配一个新变量

// Works
$results = $object->having()->take()->get();
foreach ( $results as $value ) {
    // $value is db result
}
