[Zope] Increment In PT?

[José Henrique]

Try this way:

<tal:loop repeat="item bitems">
    <input type="hidden" tal:attributes="value item/name; name
string:item_name_${repeat/item/number}">
    <input type="hidden" tal:attributes="value item/id; name
string:item_number_${repeat/item/number}">
</tal:loop>

Zenrique.
