title: Put if conditions in route laravel
body: <p>I am very new in laravel.I have following to routes and I need to check the condition if the user already exists in db then call different controller, besides I want both of these actions on a single HTML form with single to submit button that already generates the form to save new user using laravel blade engine. What action do I need to specify on the form?
  P.S the form has only one button. </p>
  
  <pre><code>Route::group(['prefix'=&gt; 'save'], function(){
  Route::get('/customer', [
      'uses' =&gt; 'CustomerController@SaveCustomer',
      'as' =&gt; 'save.customer'
      ]);
  
  Route::get('/order',[
      'uses'=&gt; 'OrderController@PlaceOrder',
      'as' =&gt; 'save.order'
  
  ]);
  </code></pre>
