Question

我写了一些雄辩的查询来获取某些条件的搜索输入结果，但结果并不像预期的那样

//i have 4 drivers registered by agent_id 12 in that 2 are pending registrations on searching name of the driver i should get only of those pending 


        public function pendingRegistrationSearch($agent_id, $search_input, $limit)
        {
            $pending_registration_search = Driver::where('agent_id' , $agent_id)
                 ->where('registration_status', 'pending')
                 ->orwhere('id', 'LIKE', '%'.$search_input.'%')
                 ->orwhere('first_name', 'LIKE', '%'.$search_input.'%')
                 ->orWhere('last_name', 'LIKE', '%'.$search_input.'%')
                 ->orWhere('phone_number', 'LIKE', '%'.$search_input.'%')
                 ->orWhere('registration_id', 'LIKE', '%'.$search_input.'%')
                 ->select('id','first_name','last_name','phone_number','registration_status')
                     ->orderBy('first_name', 'asc')
                 ->limit(30)->offset($limit)
                 ->get();

            return Response::json([
                'data' => $pending_registration_search
            ]); 
        }

    //but i'm getting all the data based on search result, data have the drivers of all the agents too

     {
      "data": [
        {
          "id": 1,
          "first_name": "Ajay",
          "last_name": "singh",
          "phone_number": "1234568790",    data of agent_id 10
          "registration_status": "pending"
        }, 
       {
          "id": 2,
          "first_name": "john",
          "last_name": "machado",
          "phone_number": "1234568790",       data of agent_id 12
          "registration_status": "processed"
        }
      ]
    }

我认为条件不起作用的前两个

谢谢

Answer 1

我不能给你一些确切的解决方案，但问题可能是你没有适用某些条件。当你使用$pending_registration_search = Driver::where('agent_id' , $agent_id) ->where(function($q) use ($search_input) { $q->where('registration_status', 'pending') ->orwhere('id', 'LIKE', '%'.$search_input.'%') ->orwhere('first_name', 'LIKE', '%'.$search_input.'%') ->orWhere('last_name', 'LIKE', '%'.$search_input.'%') ->orWhere('phone_number', 'LIKE', '%'.$search_input.'%') ->orWhere('registration_id', 'LIKE', '%'.$search_input.'%') })->select('id','first_name','last_name','phone_number','registration_status') ->orderBy('first_name', 'asc') ->limit(30)->offset($limit) ->get();时，通常应该将整个条件包装成闭包，例如：

agent_id

例如，在上面WHERE A AND (B OR C OR D)条件中将始终使用，其他条件将使用OR创建，因此您现在将获得如下查询：

WHERE A AND B OR C OR D

在您所处位置的版本中：

WHERE (A AND B) OR C OR D

与...相同：

   $pending_registration_search = Driver::where('agent_id' , $agent_id)  
         ->where('registration_status', 'pending')
         ->where(function($q) use ($search_input) {
            $q->where('id', 'LIKE', '%'.$search_input.'%')
            ->orwhere('first_name', 'LIKE', '%'.$search_input.'%')
            ->orWhere('last_name', 'LIKE', '%'.$search_input.'%')
            ->orWhere('phone_number', 'LIKE', '%'.$search_input.'%')
            ->orWhere('registration_id', 'LIKE', '%'.$search_input.'%')
         })->select('id','first_name','last_name','phone_number','registration_status')
             ->orderBy('first_name', 'asc')
         ->limit(30)->offset($limit)
         ->get();

因此，如果C或D条件为真，则根本不使用条件。

基于你写的，你也可以使用：

interface String {
  padStart(targetLength: number, padString?: string): string;
}

// https://github.com/uxitten/polyfill/blob/master/string.polyfill.js
// https://developer.mozilla.org/enUS/docs/Web/JavaScript/Reference/Global_Objects/String/padStart

if (!String.prototype.padStart) {
  String.prototype.padStart = function padStart(targetLength, padString) {
    targetLength = targetLength >> 0; //floor if number or convert non-number to 0;
    padString = String(padString || ' ');
    if (this.length > targetLength) {
      return String(this);
    }
    else {
      targetLength = targetLength-this.length;
      if (targetLength > padString.length) {
        padString += padString.repeat(targetLength/padString.length); //append to original to ensure we are longer than needed
      }
      return padString.slice(0, targetLength) + String(this);
    }
  };
}

Answer 2

我认为问题在于：

where('agent_id' , $agent_id)
->where('registration_status', 'pending')
->orwhere('id', 'LIKE', '%'.$search_input.'%')

让我们理解：

( 'agent_id' = $agent_id ) && ( 'registration_status' = 'pending' )
|| ( condition ) || ( condition ) || ( condition ) || ( condition )

这种关系在这里工作，但你需要：

( ( 'agent_id' = $agent_id ) && ( 'registration_status' = 'pending' ) )
    || (( condition ) || ( condition ) || ( condition ) || ( condition ) )

这种关系。所以我认为你可以在这里使用RAW query。

其中查询结果不符合预期
