I'm doing some screwy work with tabindexes on a form. There's a master section with sub blocks, which are presented below. The sub blocks feed total fields on the master form, so the tabindex path takes you through fields in the master till you get to the total line, drops you down to the sub block, walks you through that, and takes you up to the next line in the master form.

Code side, I'm trying to do some math to advance my tab index count ahead by the number of objects in the array used to build the sub block (in this case $products[1]) plus one.

Trick is, I'm not finding a simple way to do this with out-of-the-box smarty functions. I can't use count(), since this isn't an {if}. I tried using $products[1]|count as a modifier -- that didn't work either.

Anyone have any suggestions or would I be stuck writing a custom function or modifier?

count() should work fine inside {if}.

Inside {if}, it would. I'm using {math}.

For a modifier, you pass an entire array using @:

{$products[1]|@count}

arg! misread the "isn't".

you can do something like: {math equation="a+1" a=$foo|@count}

That did what I needed. Thanks for the tip.
