Show some text if order total > X

[MotyF]

Hi . I need display some text (with ajax) if order total is more than $500 (like: Free shipping !!)

 

If order total is less than $500 want show other text like "buy more".

 

This text I want to put in the module blocktopmenu.

 

Thanks

If you  want to put it in the top menu, I think you have no other chance but override blocktopmenu.php, hookDisplayTop, and assign $this->context->cart->getOrderTotal(); as the total amount of the current cart
