getting error: Fatal error: Call to a member function getProducts() on null in C:\xampp\htdocs\prestashop\prestashop\modules\blockaffili\blockaffili.php on line 198

 

 

1. After this error if i refresh the page then its working fine even if i clicked again.

 

 

2. Not Working: Only When i click the add to card button after order confirmation .............. if i continuously click on add to card then its working fine .......................................................

 

i checked using print_r($param)  that this happen when cart array is empty .........

Maybe test if cart is defined:

 

if (isset($this->context->cart))

{

    $products = $this->context->cart->getProducts();
