title: Symfony2 form: Money Currency Symbol and Displaying in Twig
body: <p>I've got a form in Symfony that uses the money field type with the currency set to GBP.</p>
  
  <p>When I pass the form over to twig the form is rendered using:</p>
  
  <pre><code>{{ form_row(form.price) }}
  </code></pre>
  
  <p>This renders the following html:</p>
  
  <pre><code>£&lt;input id="app_product_price" name="app_product[price]" required="required" class="form-control" value="9.95" type="text"&gt;
  </code></pre>
  
  <p>My aim is to try and get the currency symbol so I can use the bootstrap money field: </p>
  
  <pre><code>&lt;form class="form-inline"&gt;
    &lt;div class="form-group"&gt;
      &lt;label class="sr-only" for="exampleInputAmount"&gt;Amount (in dollars)&lt;/label&gt;
      &lt;div class="input-group"&gt;
        &lt;div class="input-group-addon"&gt;$&lt;/div&gt;
        &lt;input type="text" class="form-control" id="exampleInputAmount" placeholder="Amount"&gt;
        &lt;div class="input-group-addon"&gt;.00&lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;button type="submit" class="btn btn-primary"&gt;Transfer cash&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Obviously, there are some styling that I need to do. However, I've tried to get the currency symbol using the below but there doesn't seem to be any documentation that I can see to do this.</p>
  
  <pre><code>{{ form_label(form.price) }}
  
  {{ form_widget(form.price) }}
  </code></pre>
  
  <p>Neither of these seem to work to get the currency and I have also had a look into using <code>{{ form_widget(form.price.vars.currency) }}</code> which just shows errors.</p>
  
  <p>Are there any known methods of extracting the currency symbol from the form field? Or will I need to go down the route of Twig Form Theming?</p>
