忽略更新函数 Laravel 5 的唯一验证

我有这个customer当您创建时的模型具有独特的phone_num。它在创建中工作得很好，但在我的更新功能中工作得很好，这是一个基于自动填充值的表单id。如果用户只更新了address正如预期的unique验证将再次触发说The phone num has already been taken.我该如何处理这个问题？我希望用户能够更新其信息而忽略unique验证如果phone_num仍然是相同的，因此允许unique验证如果用户选择更改phone_num

My code:

public function update($id)
{
    $rules = array(
        'title'             => 'required',
        'firstname'         => 'required',
        'lastname'          => 'required',
        'gender'            => 'required',
        'birthdate'         => 'required',
        'age_bracket'       => 'required',
        'addr1'             => 'required',
        'addr2'             => 'required',
        'addr3'             => 'required',
        'addr4'             => 'required',
        'town'              => 'required',
        'country'           => 'required',
        'postcode'          => 'required',
        'phone_num'         => 'required|unique:customers',
        'phone_type'        => 'required',
        'work_status'       => 'required',
        'home_status'       => 'required',
        'marital_status'    => 'required',

    );

    $validator = Validator::make(Input::all(), $rules);


    // Check if all fields is filled
    if ($validator->fails()) 
    {
        return Redirect::to('customer/'.$id.'/edit')->withErrors($validator);
    }
    else
    {
        $customer = Customer::find($id);
        $customer->title           = Input::get('title');
        $customer->gender          = Input::get('gender');
        $customer->firstname       = Input::get('firstname');
        $customer->lastname        = Input::get('lastname');
        $customer->postcode        = Input::get('postcode');
        $customer->addr1           = Input::get('addr1');
        $customer->addr2           = Input::get('addr2');
        $customer->addr3           = Input::get('addr3');
        $customer->addr4           = Input::get('addr4');
        $customer->addr4           = Input::get('addr4');
        $customer->town            = Input::get('town');
        $customer->country         = Input::get('country');
        $customer->phone_num       = Input::get('phone_num');
        $customer->phone_type      = Input::get('phone_type');
        $customer->birthdate       = Input::get('birthdate');
        $customer->work_status     = Input::get('work_status');
        $customer->home_status     = Input::get('home_status');
        $customer->marital_status  = Input::get('marital_status');
        $customer->agebracket      = Input::get('age_bracket');

        if($customer->save())
        {
            Session::flash('alert-success', 'Form Submitted Successfully.');
        }
        else
        {
            Session::flash('alert-danger', 'Error on submitting form.');
        }

        return Redirect::to('customer/'.$id.'/edit');

    }
}

The unique规则为此目的需要一些额外的参数，看起来像unique:table,column,except,idColumn

所以就你而言，except将是id and idColumn可能是你的 id 列的名称id.

因此，考虑到这一点，您希望验证规则是......

'required|unique:customers,phone_num,'.$id.',id'
