Laravel 5.2将变量传递给查询生成器

Question

I will love to use query builder to obtain the email address of users from the database and send emails to them all, but so far i have been stuck on this for days now.

public function postSearchAction(Request $request){

      $data = array(
            'service' =>  $request->get('service'),
            'location' => $request->get('location'),
            'allProviders' => $request->get('allProviders'),
            'date' => $request->get('date'),
            'optional_skills' => $request->get('optional_skills'),
            'landmark_homepage' => $request->get('landmark_homepage'),
            'name' => Auth::user()->name,
            'userEmail' => Auth::user()->email,
            'requesterMobile' => Auth::user()->phone_number
        );




         $email = DB::table('users')->where('main_service', 'LIKE', '%'.$data['location'].'%')
            ->where('city_service', 'LIKE', '%'.$data['location'].'%')
            ->pluck('email');




      To send emails

        \Mail::send('auth.emails.serviceProviders', $data, function($message) use ($data)
        {
                $message->to($email, 'oluyemi')->subject('Test');
        });


    }

Now i have tried to use dd($mail) but the method returned an empty array. I think its worth mentioning that i once i change the variable within the query builder to the expected value, everything works fine.

Someone should please help, dont know what am doing wrong. I really need to use the variables.

Thanks for your help.

Answer 1

Please show us the raw SQL query so we can see what's wrong.
After the $email query, put:

DB::enableQueryLog();  
dd(DB::getQueryLog());

It will be the last item.

OR

Add ->toSql() instead of ->pluck() and dd() it.
