Add combinations from script in Core developers Posted February 18, 2018 On 18/9/2017 at 10:04 AM, tony_mik said: The function is a Prestashop function. To use PS functions, you call like this: include_once 'config/config.inc.php'; include(dirname(__FILE__).'/init.php'); I get error on this, telling function not defined. I tried to search in the entire prestashop code but didn't found a reference to that function. Someone can help me?
