如果复选框选择了laravel,则进行条件验证

Question

我在Laravel中有一个表单,我想根据一个复选框验证三个文本字段.它是一个编辑用户表单,如果我选择是,我只想更新密码.这是我认为的形式:

<section>
        <div class="form">
            <h1>Edit: {!! $user->name !!}</h1>
            {!! Form::model($user, ['method' => 'PATCH', 'action' => ['AccountController@update', $user->id], 'files' => true]) !!}
                <p>Name: {!! Form::text('name') !!}
                <p>Email: {!! Form::text('email') !!}
                <p>Update Password? (tick for yes) &nbsp; {!! Form::checkbox('updatepasswordcheck', 0, false) !!}
                <p>Old Password: {!! Form::password('oldpassword') !!} 
                <p>New Password: {!! Form::password('newpassword') !!}
                <p>New Password Confirm: {!! Form::password('newpasswordconfirm') !!}
                @if($user->role_id == 1) 
                    <p> User Role: {!! Form::select('user_type', ['admin', 'guest'], '1') !!}
                @else
                    <p> User Role: {!! Form::select('user_type', ['admin', 'guest'], '0') !!}
                @endif
                <p>{!! Form::submit('Update') !!}
            {!! Form::close() !!}
            @include ('errors.list_errors')
        </div>
    </section>

然后,我有一个名为EditAccountRequest的请求,如下所示:

<?php

namespace App\Http\Requests;

use App\Http\Requests\Request;

class EditAccountRequest extends Request
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {


        if($this->inputs['updatepasswordcheck'])
        {
            $rules['oldpassword'] = 'required';
            $rules['newpassword'] = 'required';
            $rules['newpasswordconfirm'] = 'required';  
        }
        $rules['name'] = 'required|min:3';
        $rules['email'] = 'required|email';

        return $rules;
    }
}

我的问题是,当我看到复选框'updatepasswordcheck'是否为真时,它永远不会起作用,因为输入始终显示为null.有人知道怎么修这个东西吗？

Answer 1

您可以在此示例中执行以下操作：

public function rules(Request $request)
{
    if($request->has('updatepasswordcheck'))
    {
        $rules['oldpassword'] = 'required';
        $rules['newpassword'] = 'required';
        $rules['newpasswordconfirm'] = 'required';  
    }
    $rules['name'] = 'required|min:3';
    $rules['email'] = 'required|email';

    return $rules;
}

Answer 2

好的,我把它解决了.我做了这个,它的工作原理:

public function rules()
{
        if($this->has('updatepasswordcheck'))
        {
            $rules['oldpassword'] = 'required';
            $rules['newpassword'] = 'required';
            $rules['newpasswordconfirm'] = 'required';  
        }
        $rules['name'] = 'required|min:3';
        $rules['email'] = 'required|email';

        return $rules;
}

Answer 3

我正在使用 Laravel 5.5 并且此代码工作正常，我的情况是如果“公司信息”下拉列表选择“是”，则应该需要“公司名称”。

控制器：

protected function validator(array $data)
{
   return Validator::make($data, [

      'company_name' => 'required_if:is_company,1',

   ]);
}

看法：

<label class="control-label">Company Info</label>
<select id="is_company" class="form-control" name="is_company">
       <option value="0">No</option>
       <option value="1">Yes</option>
</select>


<label class="control-label">Company Name</label>
<input type="text" class="form-control" name="company_name">

更干净、直接的解决方案

    $validated = $request->validate([
        .
        .
        .
        'newpasswordconfirm' => 'required|accepted',
        'oldpassword' => 'required',
        'newpassword' => $request->newpasswordconfirm === 'yes' ? 'required': 'nullable',
    ]);
