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. 2007/7/30, Peter Bengtsson <peter@fry-it.com>:
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.

I would think this should be pretty easy in the PT itself, given what you've shared so far. But I'm still not quite there. Here's what I've got:
<span tal:repeat="bitem_id bitem_ids" tal:omit-tag=""> <div tal:define="iter python:modules['ZTUtils'].Iterator(range(1000))"> <br tal:define="x iter/next" tal:replace="iter/number" />
Now, I don't really want that <br /> tag there, because it's printing a number to screen that I don't want there. However, it only prints the number "1" twice, once for each product, when it should print 1 then 2, I would think. (I presume I should just take the tal:replace out and leave the definition, but it's still not incrementing!) Later in the script I have this:
<input type="hidden" tal:attributes="value item/name; name python:'item_name_' + `x`"> <input type="hidden" tal:attributes="value item/id; name python:'item_number_' + `x`">
and other similar lines. What I'm trying to effectuate is that the "x" gets replaced with an incremented number. Can you help just a little more? TIA, Tony

You can use the ZTUtils Iterator()
<div tal:define="iter python:modules['ZTUtils'].Iterator(range(1000))"> <br tal:define="dummy iter/next" tal:replace="iter/number" /> <br tal:define="dummy iter/next" tal:replace="iter/number" /> <br tal:define="dummy iter/next" tal:replace="iter/number" /> </div>
Which might give you some freedom such as iter/Roman or iter/odd The above is practically the same as:
<br tal:repeat="i python:range(3)" tal:replace="i" />
Generally, if you can, use a Python Script or something. The Iterator is/was used in Plone templates to increment the tab index.
