Bonjour magicJu,
Quelques pistes à creuser...
AdminImportController.php
{
$id_feature = (int)Feature::addFeatureImport($feature_name, $position);
$id_product = null;
if (Tools::getValue('forceIDs') || Tools::getValue('match_ref'))
$id_product = (int)$product->id;
$id_feature_value = (int)FeatureValue::addFeatureValueImport($id_feature, $feature_value, $id_product, $id_lang, $custom);
Product::addFeatureProductImport($product->id, $id_feature, $id_feature_value);
}
Appel de la classe Feature.php
public static function addFeatureImport($name, $position = false)
Appel de la classe FeatureValue.php
public static function addFeatureValueImport($id_feature, $value, $id_product = null, $id_lang = null, $custom = false)
Cordialement
