Php 在多对多关系的情况下如何插入透视表？（拉威尔5.3）

我添加数据的表单如下所示：

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);
}

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;
}

<?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();
    }
}

当klik保存时，它将调用控制器

我的控制器是这样的：

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);
}

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;
}

<?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();
    }
}

我的服务是这样的：

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);
}

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;
}

<?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();
    }
}

我的模型用户是这样的：

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);
}

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;
}

<?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();
    }
}

创建
用户银行
模型：

 <?php
    namespace App;
    use Illuminate\Database\Eloquent\Model;
    class UserBank extends model 
    {
        protected $table = 'user_banks';
        protected $fillable = ['user_id','bank_id'];
    }

问题是您没有在
addUserBank（）
方法中传递
bank\u id
。您可以这样做：

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;
}

注意：您不需要在此处明确设置
user\u id
，因为Laravel会自动为您设置

存在错误：
字段列表中的未知列“主数据id”
。似乎addUserBank功能在服务中，附加过程仍然错误我更新我的问题。Master_数据表有一个some Master表，该表具有类型bank、order_status和payment_method。也许是这件事导致了这一错误。它起作用了。谢谢你看看我的问题。我更新了用户模型。这：
public function banks（）{return$This->belongomany（MasterData:：class，'users\u banks'，'user\u id'，'bank\u id'）->withPivot（'status'，'account\u name'，'account\u number'，'branch'）->withtimestaps（）；}
真的是这样吗？
