Conditional validation if checkbox selected laravel

Question

I have a form in Laravel in which I want to validate three text fields based on a checkbox. Its an edit user form in which I only want to update the password if I select yes. This is the form in my view:

<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>

I then have a request called EditAccountRequest like so:

<?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;
    }
}

My problem is that when I see if the checkbox 'updatepasswordcheck' is true it never works because the input always appears as null. Anyone know how to fix this?

Answer 1

Ok I worked it out. I did this and it works:

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 2

I'm using Laravel 5.5 and this code works fine, my scenario was if "Company Info" drop-down selected "Yes" then "Company Name" should be required.

Controller:

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

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

   ]);
}

View:

<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">
