title: Add a Upload File function to a custom page in Shopify
body: <p>I am very new to Shopify and the .liquid format but I want to add a file upload button to a custom contact page on my Shopify site.</p>
  
  <p>Is there a function like this that will populate a upload file option?</p>
  
  <pre><code>{{ 'contact.form.email' | t }} 
  </code></pre>
  
  <p>I tried replacing ".email" with other logical terms but nothing worked.</p>
