Hi smarty-friends

I want to have to have a couple of news in a row.
In PHP I would manage it like this :

[php:1:34531e6422]<?php
echo "<tr>";

for($i = 1; $i <= 10; $i++)
{
echo "<td>".$news[$i]."</td>";

if(($i % 2 == 0)&&($i != 10))
{
echo "</tr><tr>";
}
ecoh "</tr>";
?>[/php:1:34531e6422]
But I want to have this done in my template so I found this:

########## not relevant , skip! ################

{* Monte Ohrt March 4, 2002 *}
{* $cols is the number of columns you want *}
<TABLE border=1>
<TR>
{section name=numloop loop=$data}
<TD>{$data[numloop]}</TD>
{* see if we should go to the next row *}
{if not ($smarty.section.numloop.rownum mod $cols)}
{if not $smarty.section.numloop.last}
</TR><TR>
{/if}
{/if}
{if $smarty.section.numloop.last}
{* pad the cells not yet created *}
{math equation = "n - a % n" n=$cols a=$data|@count assign="cells"}
{if $cells ne $cols}
{section name=pad loop=$cells}
<TD>&</TD>
{/section}
{/if}
</TR>
{/if}
{/section}
</TABLE>

#######################################

The Problem lies in this part of the code :

{if not ($smarty.section.numloop.rownum mod $cols)}

I've searched the manual for further informations about mod but I dind't find anything, I know that mod is the same (?) as % in PHP but It doesn't make any sense to me.

Any help and idea is appreciated.

what does not make sense to you?

the fact that "mod" is alias for "%" (just like "and" is an alias for "&&" (somehow)) ???

or the expression:
{if not ($smarty.section.numloop.rownum mod $cols)}

which would translate to
if (! (($i+1) % $cols)) { ...
which is the same as
if ((($i+1) % $cols) != 0) { ...

???

Thanks for you quick answer but I still doesn't understand it.

This Codes says that every time `rownum` is divisible through `cols` there should be a new line.

{if not ($smarty.section.numloop.rownum mod $cols)}
</TR><TR>
{/if}

In My eyes it must be :
{if $smarty.section.numloop.rownum mod $cols == 0}
otherwise it makes no sense

sorry, my fault, of course it should read:

"if (! (($i+1) % $cols)) { ...
is merely the same as
if ((($i+1) % $cols) == 0) { ... "

that means

{if not ($smarty.section.numloop.rownum mod $cols)}
behaves just like
{if $smarty.section.numloop.rownum mod $cols == 0}

I have difficulties to understand why it is like this but it seems to be true

why $i+1 ?

and already thanks in advance ^^

{section name=numloop loop=$data}

our [numloop] (which is $i) runs from 0 to (sizeof($data)-1)
our $smarty.section.numloop.rownum runs from 1 to sizeof($data)

Great Thanx
