How to make dynamic query in laravel 5 with model and controller - laravel

Question

i have Add query in codeigniter like this:
in controller:
$data=array(
'table'=>'tbl_activity_log',
'val'=>array(
'x'=>$x,
'y'=>$y,
'z'=>$z,
));
$log=$this->model->add_data($data);
And in model add_data function like this:
function add_data($data)
{
return $this->db->insert($data['table'],$this->security->xss_clean($data['val']));
}
But In Laravel 5 I have:
$name=$Request->input('name');
$lname=$Request->input('lname');
$myItems = array(
'first_name'=>$name,
'last_name'=>$lname
);
DB::table("tbl_user")->insert($myItems);
My question is, how can we make table field dynamic in Laravel and call that function through model.
Also, how can I call that function from model? Any help please. I want a dynamic query

Answer 1

You can write a helper function
//create a helper function
function addModelData($arrayData = [])
{
return \DB::table($arrayData['table'])->insert($arrayData['val']));
}
//in your controller or any place you like
$data=array(
'table'=>'tbl_activity_log',
'val'=>array(
'x'=>$x,
'y'=>$y,
'z'=>$z,
));
$log = addModelData($data);

Answer 2

You could create a model as described in official documentation:
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
protected $table = 'tbl_user';
// If your primary key is not 'id'
protected $primaryKey = 'model_id';
}
Now in your controller you can use this model:
namespace App\Http\Controller;
use App\User;
use Illuminate\Http\Request;
class MyController extends Controller {
public function myAction(Request $request){
$user = new User();
$user->last_name = $request->input('lname');
$user->first_name = $request->input('name');
$user->save();
}
}
You also could use mass assignment. But before you have to set the $fillable attribute in your model:
protected $fillable = ['first_name', 'last_name'];
Now you can use mass assignment in your controller:
$user = User::create([
'first_name' => $request->input('name'),
'last_name' => $request->input('lname')
]);
// alternatively:
$user = User::create($request->only(['name', 'lname']));
