【问题描述】:
在 cakephp 2 中,我可以为此使用 virtualField,但在 3 中似乎是不可能的。我已经为此苦苦挣扎了两天,没有来自互联网或 cakephp 手册的运气。我没有收到任何错误,但我确实收到了空白返回。
我的控制器中的代码如下所示:
if (isset($this->request->data['location']) && (isset($this->request->data['radius']))){
$radius = $this->request->data['radius'];
$location = $this->request->data['location'];
$address = $location; // Google HQ
$HttpSocket = new Client();
$geocode = $HttpSocket->get('http://maps.google.com/maps/api/geocode/json?address='.$address.'&sensor=false');
$geocode = $geocode->json;
if ($geocode['status'] == "OK"){
$lat = $geocode['results'][0]['geometry']['location']['lat'];
$lon = $geocode['results'][0]['geometry']['location']['lng'];
$R = 6371; // earth's mean radius, km
// first-cut bounding box (in degrees)
$maxLat = $lat + rad2deg($radius/$R);
$minLat = $lat - rad2deg($radius/$R);
// compensate for degrees longitude getting smaller with increasing latitude
$maxLon = $lon + rad2deg($radius/$R/cos(deg2rad($lat)));
$minLon = $lon - rad2deg($radius/$R/cos(deg2rad($lat)));
$conditions[] = ['Venues.lat' => "'BETWEEN '".$minLat."' AND '".$maxLat."'"];
$conditions[] = ['Venues.lon' => "'BETWEEN :'".$minLon."' AND :'".$maxLon."'"];
}
$this->paginate =[
'limit' => 10,
'order' => ['Quads.date' => 'asc'],
'conditions' => $conditions,
'contain' => [
'Performers' => ['Genres'],
'Users' => ['Profiles'],
'Venues' => ['fields' => [
'name',
'id',
'verified',
'address1',
'city',
'zip_code'], 'States'=>['Countries']],
'Categories',
'Likes' => ['Users' => ['Profiles']]]];
$quads = $this->paginate();
