change default gateway based on total amount

[hogava]

Hi, 

I need use other gateway when card total is more than 400$, with this hook othergateway shown when total is more than 400$ but that is not selected and if customer doesn't select othergateway then redirected to paypal. 

How can change default selected gateway from hook?

function cart_gateway_detection($vars)

{

    if ($vars['templatefile']=='viewcart'){

        $gateways = $vars['gateways'];

        $total = $vars['total']->toNumeric();

        if ($total <= 400){

            unset($gateways['paypal']);

        }

        else {

            unset($gateways['othergateway']);

        }

        return array("gateways" => $gateways);

    }

}

add_hook("ClientAreaPageCart", 1, "cart_gateway_detection");

are you using a custom orderform template, e.g something other than standard_cart ?

because I would have thought if there are only two gateways, and the hook is removing one of them, then the cart should default the other gateway (effectively, it should be the only option shown to the user).

also, it's worth noting that the above hook isn't checking for currency - so if your site uses multiple currencies, then it would be triggered by $400, £400, €400 or ₹400 etc... in other words, it's just checking whether the total is less/equal to 400 in the current currency.

Thanks for the explanation.

Yes I use standard_cart with customized template.

This JQuery code solved my problem:

jQuery("input:radio[name=paymentmethod]:visible")[0].checked=true;

Now how can I apply this limitation about payment gateway in viewinvoice.php page too?

basically, it's still the same solution as the one I posted two years ago...

in that case, it's using limits based on the client's currency and then removing a specific gateway (e.g AsiaPay) from the dropdown - if you're only removing one gateway, then you can simply replace the content of that string... if it's multiple gateways, then you'll need multiple replaces.

thinking about it, there might be a need for an extra step with this solution - but if that's the case, you'll know as soon as you test it... that step will I suspect have been added to another hook posted elsewhere, but if you don't run into the issue, then you shouldn't need to worry about it.
