hi, i am a new smarty user...and wondering how to 'automatically' change the array that is going to looped in a foreach??

Code:
forexample:
{foreach from=$from1 item="item"}
    do something...
{/foreach}

what i want is the number 1 in $from1 is changed based on the input...
let say if i press 2, than it should be $from2...

i tried to use {foreach from=from$num ...} or something like that..
and it didnt work... Embarassed

anybody can help...really appreciate it...

PS: hope you guys can understand my question....

Maybe try:

Code:

{if $from1}
    {assign var='from' value=$from1}
{elseif $from2}
    {assign var='from' value=$from2}
{elseif $from3}
    {assign var='from' value=$from3}
{/if}

{foreach from=$from item="item"}
    do something...
{/foreach}

Perhaps you can assign all of the individual arrays you want to process into an array. That way you can index into the array to get the desired array of choice to loop over. eg:
Code:
$smarty->assign('arrays', compact( 'from1', 'from2', 'from3') );
$smarty->assign('selected', 'from2' );
---
{foreach from=$arrays.$selected item=item}
...

Generally, anytime you think you need a var-var (which Smarty does not support) consider instead a 2D array.
