如何在Smarty / Prestashop中循环数组？

Question

I use this code in Prestashop

{if (strpos($product.name, 'TVNUMBER1') !== false)}
    THIS PRODUCT IS IN SALE
{/if}

So whenever I want to display that certain products are in sale, I have to go line by line, specifying the same product i.e."TVNUMBER1". I want to be able to write an array detailing all the products I have in sale "TV1, TV2, TV3", and get a code like this:

{if (strpos($product.name, '$array') !== false)}
    THIS PRODUCT IS IN SALE
{/if}

I've tried similar examples found here, but I can't get them to work, either in Prestashop or in PHP testers online. It looks super simple, but I can't get around it.

Answer 1

I think what you want is the in_array php function, that check if a given $needle is or not in an array.

So what you should do is :

{if (in_array($product.name, '$array') !== false)}
    THIS PRODUCT IS IN SALE
{/if}

Then in your controller you can assign the array to smarty :

$arr = array('TVNUMBER1', 'TVNUMBER2', 'TVNUMBER3');
$smarty->assign('myArray', $arr);
