dynamic array key in smarty

Question

I just want to know how to access an array in SMARTY that have generated index via smarty. I want to access it later.

Got something like this:

{if $smarty.get.{param_{$k.id}_{$p.num}} eq $key}

and I like to access $smarty.get.(dynamic generated index)

Tried a couple variations, but didn't have any luck.

working right now. When I get an answer I will accept it. – pawel-kuznik Jun 19 '12 at 17:49 — pawel-kuznik, Jun 19 '12 at 17:49
have you tried {$smarty.get[$your_var]} ? – madfriend Jun 19 '12 at 18:55 — madfriend, Jun 19 '12 at 18:55
@Alex with [] don't work. Also give an parse error. – pawel-kuznik Jun 19 '12 at 23:04 — pawel-kuznik, Jun 19 '12 at 23:04

You can use variable for indexes, but you cannot build string the way you tried. Try to build a custom variable before:

{$myIndex = "param_{$k.id}_{$p.num}"}
{if $smarty.get.$myIndex eq $key}
    ...

This should work.

It is not giving an error, but var seems to be empty... Have to check if I have some sort of error in my code. – pawel-kuznik Jun 19 '12 at 23:01
Works like a charm. Still want to know why when I build string outside it goes well, but when I want to build a string in actual index it fails. – pawel-kuznik Jun 19 '12 at 23:05
I think it's by design. Your code just isn't valid Smarty syntax. – lorenzo-s Jun 20 '12 at 06:15

In my case I used UnLoCo solution and tried to directly access array content (without if statement) with dynamic key and it works perfectly :

{$arr1["column_{$arr2.month}_price"]}

Confirmed, in PS 1.6.1.12 `{$myVar["keybase_{$i}"]}` works. – jave.web Aug 21 '17 at 16:50

{if $smarty.get["param_{$k.id}_{$p.num}"] eq $key}
