Try to help myself .. 🙂
Maybe I was looking the wrong place ... i checked through module's classes ansd controllers, but i think the right file is the paypal.php on the module's root ... i find out and add or change the iso code as follow on the functions getLocaleByIso and hoockPayment
public static function getLocaleByIso($iso)
{
switch (strtolower($iso)) {
case 'it':
return 'it_IT';
case 'fr':
return 'fr_FR';
case 'hk':
return 'zh_HK';
case 'cn':
return 'zh_CM';
case 'tw':
return 'zh_TW';
case 'xc':
return 'zh_XC';
case 'dk':
return 'da_DK';
case 'nl':
return 'nl_NL';
case 'gb':
return 'en_GB';
case 'de':
return 'de_DE';
case 'il':
return 'he_IL';
case 'id':
return 'id_ID';
case 'jp':
return 'ja_JP';
case 'no':
return 'no_NO';
case 'pt':
return 'pt_PT';
case 'pl':
return 'pl_PL';
case 'ru':
return 'ru_RU';
case 'es':
return 'es_ES';
case 'se':
return 'sv_SE';
case 'th':
return 'th_TH';
case 'tr':
return 'tr_TR';
default:
return 'en_US';
}
}
and here ....
public function hookPayment($params)
{
$isoLang = [
'en' => 'en_US',
'it' => 'it_IT',
'fr' => 'fr_FR',
'de' => 'de_DE',
'nl' => 'nl_NL',
];
$this->context->smarty->assign(
[
'logos' => PayPalLogos::getLogos($this->getLocale()),
static::LIVE => \Configuration::get(static::LIVE),
'use_mobile' => true,
'PayPal_lang_code' => (isset($isoLang[$this->context->language->iso_code])) ? $isoLang[$this->context->language->iso_code] : 'it_IT',
'params' => $params,
]
);
Following some more change for express and plus checkout ... this is only for standard
I don't know if is working now ... i will update the post if solved after tested(and maybe publish an "how to^ with step by step on the italian forum if somebody find my same problem) ....
ariom's post in Paypal checkout: set LOCALECODE variable to IT was marked as the answer
