Select item from foreach on prestashop tpl file - foreach

Question

I use this code in the product.tpl file to show product categories:
{foreach from=Product::getProductCategoriesFull($product.id_product) item=cat}
{$cat.name},
{/foreach}
The result is similar to this:
Name: Lifts, Machines, Gearless,
The question is:
How can I choose what element I want to show (Lifts only, Machines only or Gearless only)??
I need to show one element from the foreach element position.

Answer 1

You should pass to your TPL only the category you want to display (calculation should be done in PHP file, not Smarty).
If you wanna go the dirty awy you can just
{break}
after first element display,
or if you want to display a certain category based on its name
just edit your code to something like :
{foreach from=Product::getProductCategoriesFull($product.id_product) item=cat}
{if $cat.name == "Lifts"}
{$cat.name}
{/if}
{/foreach}

Answer 2

Just use a if statement?
{foreach from=Product::getProductCategoriesFull($product.id_product) item=cat}
{if $cat.name == 'Machines'}
{$cat.name},
{/if}
{/foreach}

Answer 3

{assign var="loop_middle" value=Product::getProductCategoriesFull($product.id_product)|#count/2}
{foreach from=Product::getProductCategoriesFull($product.id_product) item=cat name=foo}
{if $smarty.foreach.foo.last || $smarty.foreach.foo.iteration == $loop_middle|ceil}
{$cat.name}
{/if}
{/foreach}
This will let you display last element of your array (last category):
$smarty.foreach.foo.last
This will let you display middle element of your array (middle category):
$smarty.foreach.foo.iteration == $loop_middle|ceil
