Saving selected option after validation in Laravel

I need help with saving a selected option after validation fails.

Here is main.blade.php

<form method="POST" action="">
  <select id="searchEngine" name="searchEngine">
    <option value="google">Google</option>
    <option value="bing">Bing</option>
    <option value="duckduck">DuckDuckGo</option>
  </select>

  @if ($errors->has('searchEngine'))
    <div style="background-color: #faa;">
        @foreach ($errors->all() as $error) 
         
        @endforeach
    </div>
  @endif
</form>

Controller looks like:

request()->validate(
            ['searchEngine' => "required|in:google,duckduck"],
            ['searchEngine.in' => $searchEngine.' not working, try another']
        );

I tried this, but it always returns only the last option:

<option value="google" {!! $errors->has('searchEngine') ? 'selected' : '' !!}>Google</option>
<option value="bing" {!! $errors->has('searchEngine') ? 'selected' : '' !!}>Bing</option>
<option value="duckduck" {!! $errors->has('searchEngine') ? 'selected' : '' !!}>DuckDuckGo</option>

Upon successful submission of the form, user will be redirected to a thankyou page and on the thankyou page he should be given an option to make the payment. 2. I want to create a paymentcontroller so that a new record is created, based on form submission details in relationship with the orderID attached with the form submission record. 3. the payment controller should also be able to capture payment amount, orderid etc., I am not going the regular way of cart method, its just a form to be filled for service to be rendered and payment collected for each request. I am new to programming, please help me if you can. ...
