Prestashop 1.6 CustomerAccountForm - module

Question

I created my payment module. During module's instalation i'm creating new table ps_mymodule_card with id, customer_id and card_number fields.
In register page I added new text input (card_nubmer) in account register page using hookCreateAccountForm() in module. It displays proper but how to get customer id in function hookCreateAccount($params) inside my payment module? I want to add own post data to database during (or just after) user register .

Answer 1

modules/mypaymentmodule/mypaymentmodule.php
public function hookCreateAccountForm()
{
return '<!--new field in form-->'
. '<div class="form-group">'
. '<label for="card_number">'
. 'Card number:'
. '</label>'
. '<input class="form-control" id="card_number" type="text" name="card_number">'
. '</div>'
. '<!--new field in form-->';
}
public function hookCreateAccount($params)
{
[here put some validation of data]
$cadrNumber = $params['_POST']['card_number'];
$customer = $params['newCustomer'];
$db = Db::getInstance();
$query = 'INSERT INTO `'._DB_PREFIX_.'mymodule_card`
(`customer_id`, `card_number`)
VALUES
("'.intval($customer->id).'", "'. intval($cadrNumber).'")';
$db->Execute($query);
}
function below is calling of course during module instalation!
private function _createMymoduleCardTbl()
{
$db = Db::getInstance();
$query = "CREATE TABLE IF NOT EXISTS `"._DB_PREFIX_."mymodule_card` (
`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`customer_id` INT NOT NULL ,
`card_number` TEXT NOT NULL
) ENGINE = MYISAM ";
$db->Execute($query);
return TRUE;
}
do not forget about hooks registering in install method!!
$this->registerHook('createAccountForm')
$this->registerHook('createAccount')
