[Zope] Increment In PT?

[tonylabarbara at aol.com]

It's complaining that:

Error Type: TypeError
Error Value: string indices must be integers


I tried back ticks and that still gave the same error.
TIA,
Tony


<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>

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.

You should now have all the parts.
Instead of iterating over python:range(1000) do it on bitem_ids instead.

You don't have to use a <br /> tag. You can use
<input tal:attributes="value iter/number" /> 
if you want.
You increment it by calling tal:iter/next whichever way you do it.
