    Hi there



    I installed ok, created a coupon, setup the options as:



    Function type: coupon



    uses: 5



    percent: total



    Value: 20



    Exp date: 3-9-2010



    Selected all customers and chose the product:



    http://174.133.102.130/~elavon/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=101&category_id=65&option=com_virtuemart&Itemid=92



    But i dont see a "enter coupon code" field or how the coupon affects the price?

    It looks like you have coupon codes disabled.  log in as an admin, go to components->virtuemart->admin->configuration.  Select the Global tab and make sure "Enable Coupon Usage" is checked.

    Your awesome



    So far this looks great!



    One more question - I have a exp date of today - March 9th, but I can still see the coupon. Is that correct?

    Yes, none of the coupons are ever deleted, so you can see a history of all your coupons, although you can delete them manually.  So that is why the filtering is so important.  If a customer tries to use a coupon that has expired, it wont work.  On the dashboard, you can click on active coupons or inactive coupons.  Inactive coupons will filter to all coupons that are unpublished and coupons that have expired (whether published or not).

    Hi there,





    The coupon code doesn't appear even if I enable the coupon in the admin global configuration. And I've already edit the codes to your instruction. I'm not sure what went wrong.



     



    Here is my ps_coupon.php

    The code looks right.  When you say the coupon code doesnt appear, do you mean you do not see a box in the checkout to enter a coupon code?  If so that seems like a virtuemart problem.  can you supply the url?

    Ok great but is there a way to NOT show the coupon after it expires? I have an expired one, that doesnt work but it should just disappear from the page after.

    sorry, i do not automatically delete coupon codes. when viewing the list of coupons, you can check it and select delete from the top right to delete a specific coupon.

    May be I get confuse about how the code should appear. Anyway the box for entering the coupon code in the checkout page is appear normally. So can you explain me how the system is going to acknowledge the customer that he/she get the coupon code when the value is reached? Should the system show the code automatically on the checkout page? Or will the system email any coupon code to the customer?

    Thank you :)

    this system does not advertise your codes to customer. it just allows you to maintain your coupon codes. to get customers to use them, you would have to do an email campaign or advertise coupon codes on sites, or other campaigns. for the checkout process, the customer would never see the code while checking out. they will have an opportunity to put in a code, and if it is a valid code, the discount will be shown on the shopping cart (without showing the code), otherwise they would receive a generic error saying the code is not valid.

    hope that helps.
