    Hi mate,

    I purchased and installed AWOcoupon at www.australianonlinecollege.com.au. It is all working perfectly and I am very happy I went with AWO. However I have one strange problem:

    When a user enters a coupon with a value that is higher then the total order price, the user should (supposedly) not have to enter their payment details as the products would be free. However, this does not seem to work - I still have to enter payment details when the total order amount is $0.00.

    Any ideas?

    Cheers!

    Are you using virtuemart 1.1.4 or 1.1.5?
    In my tests, it works fine in 1.1.4, but in 1.1.5 it does not skip the payment method screen.

    Did some more testing, and I believe it can happen on both 1.1.4 and 1.1.5. It seems to be a rounding issue. When it does the check, sometimes the order total is 0.001523 and that is checked to see if it is 0, obviously it is not. So I would round the order total to 2 decimal places to fix this.

    In www/administrator/components/com_virtuemart/classes/ps_checkout.php, around line 860 change
    <?php
    elseif( isset($order_total) && $order_total 
    ?>


    to

    <?php
    elseif( isset($order_total) && round($order_total,2
    ?>


    that should fixe the problem

    Hi Seyi,

    following your great advice once again solved this problem
    but I noticed that when giftcert > total order, total order in checkout = "-0.00EUR"

    Of course it's not a real problem ...

    So I looking deep into ps_checkout file, and noticed an other place where you "round" solution can fit, and this solved this "minus" issue :


    Find
    <?php
            
    if( empty( $_REQUEST['order_total'])) {
                
                if( isset( 
    $d['order_total'])) {
                    if( 
    round$d['order_total'], 
    ?>


    And replace by

    <?php
            
    if( empty( $_REQUEST['order_total'])) {
                
                if( isset( 
    $d['order_total'])) {
                    if( 
    round$d['order_total'], 
    ?>


    Does it look right to you ? :)

    It would be great if the customer doesn't have to choose a payment method and VM set this automatically for Zero orders :/

    You should post that in the virtuemart forum. AwoCoupon has no control over the payment methods.

    Sorry seyi,

    Have researched a lot there .... without answers .... I will open a new topic. Thank you for answers, this is the best and fastest support. I feel safe in acquiring the coupons component and some plugins, I'll make the purchase today! ;)
