Smarty concat / foreach分配

Question

I have a main array:

$occupations = ['hs','uni','parent'];

and other multiple array of type

$columns_hs;$columns_uni;

etc. I want to foreach through the "$occupations" array and then foreach through the other arrays but cant seem to get the right syntax. Here is my code:

{foreach from=$occupations item=ov key=ok}
    {foreach from=$columns_`$ov`}
        do something
    {/foreach}
{/foreach}

Answer 2

Declare one array colums

$colums = array(
 'hs' => [1,2,3,4],
 'uni' => [5,6,7,8]
);

and your code in foreach is

{foreach from=$occupations item=ov key=ok}
    {foreach from=$columns[$ov]}
        do something
    {/foreach}
{/foreach}
