Hi to all.
I need to programmatically change the logo in email templates.

How to work with parameters in the hook?

My custom image my-custom-logo.jpg not changed in mail templates.

This params not work:

$params['templateVars']['{shop_logo}'] = $logo;

Full code:

public function hookActionEmailSendBefore($params)
{
	$id_lang = $params['idLang'];
    $templateVars = $params['templateVars'];
	$id_order = $templateVars['{id_order}'];
	$id_shop = $params['idShop'];
		
	$get_custom_logo = _PS_IMG_DIR_.'my-custom-logo.jpg';
		
	if (file_exists($get_custom_logo)){
			$logo = $get_custom_logo;
	} else {
			if (false !== Configuration::get('PS_LOGO_MAIL') && file_exists(_PS_IMG_DIR_ . Configuration::get('PS_LOGO_MAIL', null, null, $id_shop))) {
                $logo = _PS_IMG_DIR_ . Configuration::get('PS_LOGO_MAIL', null, null, $id_shop);
        } else {
            if (file_exists(_PS_IMG_DIR_ . Configuration::get('PS_LOGO', null, null, $id_shop))) {
                    $logo = _PS_IMG_DIR_ . Configuration::get('PS_LOGO', null, null, $id_shop);
            } else {
                $templateVars['{shop_logo}'] = '';
            }
        }
	}
		
		$params['templateVars']['{shop_logo}'] = $logo;

		return;
}

Thank you
