How do you increment an assigned variable in smarty without displaying it

Question

So I have an assigned variable in smarty:

{assign var=number value=0}

Now I can increment it using

{$number++}

Answer 1

Better to use the built in Smarty "counter" >> {counter} element.

So, in template you can use:

Some text, html code, whatever... 
{* init the counter! *}
{counter start=0 print=false} {* now the tpl doesn't show the "0" number *}


{* 3x run :D *}
{some_cyclic_stuff_like_foreach_or_section}
    Run the counter: {counter}
{/some_cyclic_stuff_like_foreach_or_section}

It will print for you:

Run the counter: 1
Run the counter: 2
Run the counter: 3

So, at least, you can use it with the print=false option, and you have the counter but it's hidden.

If you use it the "variable way" (like the upper section write) you also can hide it with html/css or just simply don't let it print :)
