[Zope] Increment In PT?

[tonylabarbara at aol.com]

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.
