checkout message duplicate

[wakabayashi]

Hello

 

I use Prestashop 1.6.0.8. I am working on checkout. When my customer are on the step "3. Adresse" they can add a comment. But when they go own to "4. Shipping" The comment field is away. I want to display this comment field on all steps.

 

How is it possible?

 

I tried to add

{if !$opc}
<div id="ordermsg" class="form-group">
<label>{l s='If you would like to add a comment about your order, please write it in the field below.'}</label>
<textarea class="form-control" cols="60" rows="6" name="message">{if isset($oldMessage)}{$oldMessage}{/if}</textarea>
</div>
{/if}

but this doesnt work. I see the field, but the comment doesnt save (cant see it in admin).

 

Thanks for your help!

you want to display it only ? or you want to give cusomers possibility to alter that texxt?

if second, it will be necessary to modify controllers too, not only .tpl file
