Load specifics packs in product.tpl

[REPrint]

Hi!

I have a strange situation.

I need to load on product.tpl 2 special pack. I know the IDs.

I make some coding and, when i call like 

{foreach from=$buytogetherId item=buyId} 

{assign var='buyt' value=Pack::getItems($buyId, $cookie->id_lang)}

{$buyt|print_r}

{include file="$tpl_dir./product-list.tpl" products=$buyt}

{/foreach}

 

i have error:

Warning: array_key_exists(): The first argument should be either a string or an integer in /home/r52276hqto/public_html/classes/Pack.php on line 119

Warning: Illegal offset type in /home/r52276hqto/public_html/classes/Pack.php on line 149

 

HOW CAN I LOAD THIS IN PRODUCT VIEW

The warnings come from

Pack::getItems($buyId, $cookie->id_lang);

Make sure $buyId is string or integer. try to print it before getting items see what is the result

{foreach from=$buytogetherId item=buyId} 
{$buyId}
