How to add data to additional column in pivot table in laravel

Question

I'm trying to build an app in Laravel 5.3, I want to add additional column data in the pivot table. Following is my code:

My Users model:

public function relations()
{
  return $this->belongsToMany('App\Plan')->withPivot('child');
}

My Plan model:

public function relations()
{
  return $this->belongsToMany('App\User')->withPivot('child');
}

In my controller I'm fetching the user data from Auth::user(); and for plans and child element I'm getting through request. I want to store this to my pivot table. Following is the code which I tried in my controller:

$user = \Auth::user();
$plan_id = $request->plan_id;
$childid = $request->child_id;
$plan = App\Plan::find($plan_id);
$user->relations()->attach($plan, ['child' => $childid]);

Help me out in this.

Answer 1

You should use attach() like this:

$user->relations()->attach($plan_id, ['child' => $childid]);
