This is the code used:

<code>

<div t-attf-class="form-group #{error and 'category' in error and 'has-error' or ''}">

<label class="col-md-3 col-sm-4 control-label" for="name">IP Phone </label>

<div class="col-md-7 col-sm-8">

<input type="checkbox" name="x_ipphone" value="{{x_ipphone}}"/>

</div>

</div>

</code>

Actually i want to add additional field to "Website Support Module"

i already add the new field "x_ipphone" and "x_problem", it works fine in Form View

but it doesn't work or responding  in the website qweb form where the user try to add a new support ticket

how can i add the new customized fields to the qweb form.

According to your Odoo version, field starting with x_ or field existing in model can be automatically save.

But if your field is call ip_phone, it's probably a customization in python.

So you need to override the controller

or match exactly the same name in odoo 9, but you need to whitelist the field before.

Which version are you using ? 

8 ? 9c ? 9e ? ...?
