How to insert pivot table in case of many to many relation? (Laravel 5.3) - php

Question

My form to add data is like this :
When klik save, It will call controller
My controller is like this :
public function store(Request $request)
{
$param = $request->only('account_name','account_number','bank_id','branch');
$result = $this->user_service->addUserBank($param);
if($result)
$status='success';
else
$status = 'failed';
return redirect('member/profile/setting/account')->with('status',$status);
}
My service is like this :
public function addUserBank($param)
{
$instance = User::where('id', '=', auth()->user()->id)->first();
$param['user_id'] = auth()->user()->id;
$param['status'] = 0;
$instance->banks()->attach([
'status' => $param['status'],
'account_name' => $param['account_name'],
'account_number' => $param['account_number'],
'branch' => $param['branch']
]);
return $result;
}
My model user is like this :
<?php
namespace App;
use App\Models\MasterData;
use Collective\Html\Eloquent\FormAccessible;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable, FormAccessible;
protected $fillable = [
'name', 'email', 'password', 'api_token','birth_date','mobile_number','gender','full_name'
];
protected $hidden = [
'password', 'remember_token',
];
public function banks()
{
return $this->belongsToMany(MasterData::class, 'users_banks', 'user_id', 'bank_id') ->withPivot('status','account_name','account_number','branch')->withTimestamps();
}
}
So I have 3 table : users table, users_banks table (pivot table), and master_datas table
List of the names of the banks located in the master_datas table with type bank
Users table have field id, name, email, password etc => See model user
Master_datas table have field id (this is bank id), name (this is bank name), type (there exist type of bank, order status etc. So, get type = bank)
Users_banks table have field id, user_id, bank_id, status, account_name, account_number, branch
When run, it does not successfully insert into the pivot table (table users_banks).
It looks like my way to insert into the pivot table, not true.
Can you help me?

Answer 1

The problem is that you are not passing bank_id in your addUserBank() method. you can do it as:
public function addUserBank($param)
{
$param['status'] = 0;
auth()->user()
->banks()
->attach($param['bank_id'], array_only($param, ['status', 'account_name', 'account_number', 'branch']);
return true;
}
Note: You don't need to set user_id explicitly here as Laravel will automatically do it for you.

Create UserBank model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class UserBank extends model
{
protected $table = 'user_banks';
protected $fillable = ['user_id','bank_id'];
}
And then populate the table from controller:
public function store(Request $request)
{
$param = $request->only('account_name','account_number','bank_id','branch');
$result = $this->user_service->addUserBank($param);
if($result)
{
$pivot=new UserBank();
$pivot->user_id=auth()->user()->id;
$pivot->bank_id=$request->bank_id;
if($pivot->save())
{
$status='success';
}
}
else
{
$status = 'failed';
}
return redirect('member/profile/setting/account')->with('status',$status);
}
