title: How to check if Laravel request has no input
body: <p>I would like to display a text only when my <code>request</code> does not contain any <code>input</code>s</p>
  <p>At the moment, a product list is displayed on the following page: <code>/products</code>. On that same page, there is a form with several inputs to filter the products.</p>
  <p>If I filter by price, I get the following URL once the GET form is submitted: <code>/products?price=true</code></p>
  <p>I am using the following condition to check if the request has a price input:  <code>if(Input::has('price'))</code></p>
  <p>This works fine, but I have several other request parameters, and I would like to display the text only when none of those inputs are filled.</p>
  <p>This is what I have so far, it works, but it is not ideal:</p>
  <pre><code>@if(Input::has('price')||Input::has('mixed')||Input::has('male')||Input::has('female')||Input::has('kid')||Input::has('page'))
    //Do nothing
  @else
    //Display my text here
  @endif
  </code></pre>
  <p>Is there a way to do something similar but in much simpler way?</p>
