How to bind parameters to a raw DB query in Laravel that's used on a model?

Re,

I have the following query:

$property = 
    Property::select(
        DB::raw("title, lat, lng, ( 
            3959 * acos( 
                cos( radians(:lat) ) * 
                cos( radians( lat ) ) * 
                cos( radians( lng ) - radians(:lng) ) + 
                sin( radians(:lat) ) * 
                sin( radians( lat ) ) 
            ) 
        ) AS distance", ["lat" => $lat, "lng" => $lng, "lat" => $lat])
    )
    ->having("distance", "<", $radius)
    ->orderBy("distance")
    ->take(20)
    ->get();

It doesn't work: Invalid parameter number: mixed named and positional parameters.

Does anyone know a trick or a workaround (I can obviously write the full query but prefer to use fluent builder).

I ported the nearby search from Doctrine v1 to Laravel, check it out here.

Just add the Geographical trait to the model then you can do:

$model->newDistanceQuery($request->query('lat'), $request->query('lon'))->orderBy('miles', 'asc')->get();

It works by using selectRaw with bindings like this:

$sql = "((ACOS(SIN(? * PI() / 180) * SIN(" . $latName . " * PI() / 180) + COS(? * PI() / 180) * COS(" . $latName . " * PI() / 180) * COS((? - " . $lonName . ") * PI() / 180)) * 180 / PI()) * 60 * ?) as " . $unit;
if($kilometers){
    $query->selectRaw($sql, [$lat, $lat, $lon, 1.1515 * 1.609344]);
}
else{
    // miles
    $query->selectRaw($sql, [$lat, $lat, $lon, 1.1515]);
}
