Problem with regex_replace in prestashop smarty

Question

I'm trying to use regex_replace in prestashop product_list.tpl. My code is like:

{$product.description|regex_replace:".*(?=Kompatybilny)":""|strip_tags:'UTF-8'}

I'd like it to show $product.destription after "Kompatybilny" word, but it doesn't work and I don't know why. I've tried different regex functions but still the same - variable doesn't show at all.

Try "/.*?(?=Kompatybilny)/su" instead of ".*(?=Kompatybilny)" — Wiktor Stribiżew

@WiktorStribiżew Perfect! Works as expected. Could you tell me one more thing? How to make it to show part of variable between 2 words? — Patryk

Something like {$product.description|regex_replace:"/.*?Kompatybilny(.*?)Word2.*/su":'$1'}? — Wiktor Stribiżew

You may use

{$product.description|regex_replace:"/.*?(?=Kompatybilny)/su":''}

The regex will match

.*? - any 0+ chars, as few as possible, up to (but excluding from the match) the first occurrence of
(?=Kompatybilny) - the Kompatybilny substring
su - s means . can match linebreak chars and u supports Unicode strings.
