title: prestashop 1.6 get all products
body: <p>I want to get all products of my Prestashop 1.6.</p>
  
  <p>Can someone learn me to get all products?
  Something like</p>
  
  <pre><code>    $products = Controller::getAllProducts();
  </code></pre>
  
  <p>or</p>
  
  <pre><code>    $products = Controller::getProducts();
  </code></pre>
  
  <p>And if this is not possible, how get products by category using a HTML select?</p>
