Custom fields displaying in BO but not in FO

[Xuân]

Hi everyone,

I tried to add custom fields to one of my form following this tutorial : http://nemops.com/new-customer-address-fields-prestashop/

But once I finished the tuto it doesn't appears in the front office, only in the back... I suppose that stgh in the newer version ( 1.6.0.14 for me ) slightly changed compared to nemo's one since I'm not the only one to get this problem, seeing the comments. I tried to fix my Address.tpl, assuming that the error is here, but couldn't succeed.

Ofc, I cleared my cache and forced recompilation.

So if anyone has an idea of why this code doesn't work for the FO I'd be really happy !

{if $field_name eq 'my_custom_field'}
    <div id="vat_area">
        <div id="my_custom_field">
            <div class="form-group">
                <label for="my-custom-field">{l s='My Custom Field'}</label>
                <input type="text" class="form-control validate" data-validate="{$address_validation.$field_name.validate}" id="my-custom-field" name="my_custom_field" value="{if isset($smarty.post.my_custom_field)}{$smarty.post.my_custom_field}{else}{if isset($address->my_custom_field)}{$address->my_custom_field|escape:'html':'UTF-8'}{/if}{/if}" />
            </div>
        </div>
    </div>
{/if}

Thanks in advance and have a good day !
