hi, i'm still new to smarty so i hope to receive some help with the problem below:

how do i change the following {section} into {foreach}?

Code:
{section name=outer loop=$row}
<tr>

{section name=inner loop=$row[outer]}

<td>{$row[outer][inner]}</td>

{/section}

</tr>
{/section}


$row is an assoc. array in the form of $row[number][alpha]. i've been trying hard to change but none of what i tried works. Crying or Very sad

also, i don't quite understand the usage of item attribute of foreach... can someone explain it to me more in-depth?

i also understand that the limitation of foreach is that it can only be used for a single array... what does that means?

thanks in advance for your reply as it means alot to me Wink

do you know php's foreach? ( http://php.net/manual/en/control-structures.foreach.php )

this php-foreach-loop:
[php:1:91e45f8f65]foreach ($array as $name=>$value) { echo $value; }[/php:1:91e45f8f65]
is comparable to this smarty-foreach-loop
Code:
{foreach from=$array key=name item=value} {$value} {/foreach}

( "item=value" makes $value being updated on each iteration)

me either. i think people saying this, mean, that you can do this with sections:
Code:

{section name=foo from=$array}
var1: {$array[foo]}
var2: {$another_array[foo]}
{/section

(funky, not? ) but not with foreach.

but with foreach's "key"-attribute you get a comparable option:
Code:

{foreach name=foo from=$array key=i item=not_used_but_required}
var1: {$array.$i}
var2: {$another_array.$i}
{/foreach}



to me {foreach} is far more intuitive than {section}, but maybe this is because i knew php's foreach far earlier than the existence of smarty Smile

thanks for your explanation messju!

i managed to solved my problem after reading it... thanks man!

in case anybody wants to know, it is:

Code:
{foreach from=$row key=number_row item=number}
<tr>

{foreach from=$number key=assoc_array item=value}
<td>{$value}</td>
{/foreach}

</tr>
{/foreach}
