Hi all,
I'm new to using Smarty, and I have a template where I'm wanting the first 25 items of the array returned on the first page, and then the remaining ones on the second page.

The code I have currently is below, but I'm getting a series of blank lines (being total array length less 25) after the first 25 array entries on the first page, and a series of blank lines (being 25) before the remaining entries on the second page. I'm sure there is a tidier way of doing this that produces just the 25 rows on the first page and remaining on the second page. How do I do that?

On Page One I have:

Code:

{foreach from=$crt_certificates_prd_products_1 item=IDENTIFIER}
  {if $IDENTIFIER@index lt 25}
    {$IDENTIFIER@index} - {$IDENTIFIER.name}
  {elseif $IDENTIFIER@index gte 25}
    {break}
  {/if}
{/foreach}


Then on Page Two I have:

Code:

{foreach from=$crt_certificates_prd_products_1 item=IDENTIFIER}
  {if $IDENTIFIER@index lt 25}
    {continue}
  {elseif $IDENTIFIER@index gte 25}{$IDENTIFIER@index} - {$IDENTIFIER.name}
  {/if}
{/foreach}


I've not found anything in the forum that has answered this, but will happily go read any posts you can point me to,
thanks in advance,
Ben.[/code]

Do pagination in your PHP code, not in Smarty code.

This effect could be caused by Smarty honoring line endings after the control structure tags. If so, you may need to run the tags together:
Code:
{foreach from=$crt_certificates_prd_products_1 item=IDENTIFIER}{if $IDENTIFIER@index lt 25}{$IDENTIFIER@index} - {$IDENTIFIER.name}
{* don't actually need this {elseif $IDENTIFIER@index gte 25}{break} *}{/if}{/foreach}


You might also try a simple {for} loop:
Code:
{for $i=0 to count($crt_certificates_prd_products_1) max=25}
    {$i} - {$crt_certificates_prd_products_1[$i].name}
{/for}

{for $i=25 to count($crt_certificates_prd_products_1)}
    {$i} - {$crt_certificates_prd_products_1[$i].name}
{/for}
