Display remaining amount based on Ajax in Shopping Cart

[Kamil K]

Hi,

I have recently started to work with the display of the missing amount to give a discount. This information displays above the basket in the form: " You are missing xxx.xx EUR for the -10% discount". I have added a simple piece of code in the cart.tpl file, while I would like this information to be displayed using AJAX.

I'll make no secret of the fact that I'm green in this subject and I don't really know what variables I need, and whether it's necessary to define additional variables or simply call the cart refresh again. Below I add a snippet of HTML code with the Smarty Variables addon as it works now.

The shop is based on the IQIT Warehouse theme.

    {elseif $cart.totals.total.amount > 1000 && $cart.totals.total.amount < 2000}
        <h4 style="font-weight:400; text-align: center; width: 100%; height: 95px; background-color: #aeaeae; padding-top: 20px;">
        <span style="color: white;">Brakuje Ci {2000-$cart.totals.total.amount} PLN netto aby otrzymać 13% rabatu na całe zamówienie </span>
        </h4>
    {elseif $cart.totals.total.amount > 2000}
    {/if}

Thanks in advance for your help
