Conditional validation if checkbox selected laravel

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> <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?

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;
}

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>Company Info</label>
<select name="is_company"> <option value="0">No</option> <option value="1">Yes</option>
</select>
<label>Company Name</label>
<input type="text" name="company_name">

More Detail

You could do the following in this example:

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;
}

A cleaner and straight forward solution

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

may be can use required_unless for this purpose:

$this->validate($request, [ 'content' => 'required_unless:otherfields,null', ], [ 'content.required_unless' => 'Please enter content for detail' ]);

there is another way to Take a look at the sometimes rule. This will run the rule only when the field is available:
