Manipulation of session variables in prestashop 1.7

[israelmekomou@gmail.]

Hi,

I'm new in prestashop and i am creating a module that manage the shipping cost depending on the shippind day chosed by the customer and i want to save the date in a session variable.

I've tried using cookies but i dont realy know if i use it wrongly but it's not working.

Hello:

Post here you code so we can help you. You can use cookies without problem:

Context::getContext()->cookie->your_var = 'some value';

There is better way to do so in 1.7.x versions.

You make a function in the respective controller

private function _getSession()
{
	return \PrestaShop\PrestaShop\Adapter\SymfonyContainer::getInstance()->get('session');
}

And then where you need it, first you assign using

$this->_getSession()->set('yourVariableName', $wanted_value);

then where you need to get the value

$choice = $this->_getSession()->get('yourVariableName');

Checked (and working) in 1.7.6.3 (latest at the moment of composing this message) either for front or admin module controllers.

Tried to make it working for the main module class but with no success for the moment.

Hi @tapanda.gr

What about if I need to use $choice in tpl ?

Thanks.

As long as you have got the value in the variable then you make

$this->context->smarty->assign(
	array(
		...
		'choice' => $choice,
		...
	)
);

in the controller (where ... means other variables obviously).

Happy coding and happy Easter (if you are Orthodox).

$this->_getSession()->unset('yourVariableName');

Is this method good? Is there some other way to disable sessions?

[arvistar]

"unset" doesn't work. Correct solution: "remove"

$this->_getSession()->remove('yourVariableName');

I'm facing the same problem. the hook i use is fired 3 times. It's not an elegant fix but atleast your solution it's working.

Thanks!
