smarty name of variable dynamic - templates

Question

I'm studying smarty for about two months and I find myself be in front of a problem.
I am creating a dynamic menu that reads the configuration from a file called submenu.conf in this file are:
tot_sub_menu_2 = "2"
text_sub_menu_2_1 = "Home"
text_sub_menu_2_2 = "about"
tpl file in my application I wish he would create the menu dynamically in this way:
{for $foo=1 to #tot_sub_menu_2#}
<li>{#text_sub_menu_2_.{$foo}}</li>
{/for}
I would like to take a dynamic parameter text_sub_menu_2_1 the second loop becomes text_sub_menu_2_2 etc.
someone knows how to help me?

Answer 1

I have not tested but you can try using {counter}
{for $foo=1 to #tot_sub_menu_2#}
{* initialize the count *}
{counter start=0 skip=1}
<li>{#text_sub_menu_2_.{counter}}</li>
Otherwise you can make use of the #iteration property. See http://www.smarty.net/docs/en/language.function.foreach.tpl#foreach.property.iteration
iteration contains the current loop iteration and always starts at
one, unlike index. It is incremented by one on each iteration.
{foreach from=$new_products item='product' name='newProducts'}
// Do somthing
//Here i want to increment {$count} if it's lower than 3 or set to 1 if higher than 3
{if $product#iteration <= 3}{$count = $product#iteration}{else}{$count = 1}{/if}
{/foreach}
