[2grosiek7]

Hi,

I'd like to know, that is any possibility, to use function in prestashop, which could check first letter od word? I know, that is possible to change letter. How it should be write in code?

Thanks in advance

Uhmm.. You should be more precise about this question because there is a plenty of ways to check this.

For example, I want to have an effect only if reference index starts from BLNIKE(XXXX) - where in (XXXX) is random number.

If You want to have impact on product.tpl (which I assume you want) you should try this code 

{if strpos($product->reference, 'BLNIKE') != false} 
 Your HTML CODE
{/if}
