title: how to create form elements with custom name in cakephp?
body: <p>I am working on existing project. There are many forms like this:</p>
  
  <pre><code>&lt;?php echo $form-&gt;create('MyForm', array('id' =&gt; 'MyFormId')); ?&gt;
  
    &lt;?php echo $form-&gt;input('User.0.username', array( 'label' =&gt; false, )); ?&gt;
    &lt;?php echo $form-&gt;input('User.0.location', array( 'label' =&gt; false, )); ?&gt;
  
  &lt;?php echo $form-&gt;end(); ?&gt;
  </code></pre>
  
  <p>It is generating form elements like this:</p>
  
  <pre><code>&lt;input type="text" id="User0Username" name="data[User][0][username]"&gt;
  &lt;input type="text" id="User0Location" name="data[User][0][location]"&gt;
  </code></pre>
  
  <p>Bu I want them to be look like this:</p>
  
  <pre><code>&lt;input type="text" id="User0Username" name="User_0_username"&gt;
  &lt;input type="text" id="User0Location" name="User_0_location"&gt;
  </code></pre>
  
  <p>Is there any <code>$form-&gt;create();</code> function option to get this html instead of changing my forms elements?</p>
  
  <p>Thanks</p>
