Re: [htmltmpl] loop counting

[Michael G. <gr...@ya...>]

Thanks, Mathew, for the response.  That looks easy enough.  Now, what if I have two nested tmpl_loops and I want to only apply the break tag on the first set of nested template loop date?  

For example:

<tmpl_loop albums>
 
<tmpl_loop pictures>
    ...
    <img src="<tmpl_var src>" alt="" />
   <tmpl_if expr="(__counter__ % 3) == 0 && PARENT_LOOP_COUNTER < 1"><br /></tmpl_if>

</tmpl_loop>
</tmpl_loop>

Can I "see" the counter for the parent loop inside the child loop?

Thanks.

sure thing - but it does require using H::T::Expr. 
I use the following snippet as-is to a gallery of photo's.  Notice the
use of modulo (%).

  Hello,

I have a series of images that I would like to output but I want to limit it to only 4 images per row.  I would like to put a br tag to force the 5th, 9th, etc... image to go to the next row.  Can I do this completely int the template using an iterator or resettable counter?

Thanks,

greanie
