在用户登录中，一位邮政编码为90001的用户想要在5公里范围内搜索诊所邮政编码90003。搜索后，他获得了90001 90002 90003的位置，但在我而言，不是吗？为什么？ 检查以下代码
//Search Controller

答案 0 :(得分：0)
要获取5公里左右的位置，您需要在试用表中保存纬度和经度列以及邮政编码。
从试用表中获取给定邮政编码的纬度和经度。
在您的控制器中。
$data = Trial::where('zipcode',$request->zipcode)->select('latitude','longitude')->first();
$lat = $data->latitude;
$lng = $data->longitude;
$distance = 5 // Diatanse in kms
$query = Trial::getByDistance($lat, $lng, $distance);
$ids = [];
//Extract the id's
if(!empty($query)) {
foreach($query as $q)
{
array_push($ids, $q->id);
}
}
// Now write final query
if(!empty($ids)){
$results = DB::table('Trial')->whereIn( 'id', $ids)->where('your other conditions here ');
}
试用模式：
public static function getByDistance($lat, $lng, $distance)
{
$results = DB::select(DB::raw('SELECT id, ( 3959 * acos( cos( radians(' . $lat . ') ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(' . $lng . ') ) + sin( radians(' . $lat .') ) * sin( radians(lat) ) ) ) AS distance FROM articles HAVING distance < ' . $distance . ' ORDER BY distance') );
return $results;
}
注意：语法可能会更改，但登录可能会有用。
