[PF22]

Hi there

 

I try to used to an old customized module in my Prestashop that runs with php 7.0. I got an error and no idea...

Fatal error: Uncaught Error: Call to undefined method Product::getFrontFeaturesHiddenByNameStatic() 

And here is the line of code.

$feature = Product::getFrontFeaturesHiddenByNameStatic((int)($params['cookie']->id_lang), $product['id_product'],'_Descriptif accueil');

And that function is defined in "override" folder.

public static function getFrontFeaturesHiddenByNameStatic($id_lang, $id_product, $featureName) {
    self::getFrontFeaturesStatic($id_lang, $id_product);
    if( isset(self::$_frontFeaturesCacheHidden[$id_product.'-'.$id_lang]) )
    foreach(self::$_frontFeaturesCacheHidden[$id_product.'-'.$id_lang] as $feature) {
        if( $featureName == $feature["name"] )
            return $feature;
    }
    return null; // nothing has been found
}

Thanks in advance !
