Blocking usage of Group Discount & Discount Coupons

[familynow]

Hi.

I'd like to prevent ppl from redeeming a discount coupon code when their in a discount group. Is that possible?

[familynow]

Perhaps some background info would help?

I'm doign a WagJaw campaign(CDN groupon clone) and I'm selling a membership that will entitle clients to a discount for a year. I was hoping to use group pricing for this but I hadn't realized they could also redeem coupons on top of the group pricing discount. Is there a way to add restrictions to group pricing or perhaps do this another way. Worst case I guess I could give everone a coupon code they they'd have to enter at every purchase that way they could only apply a single discount but that's allot of overhead when I could just have them part of a group.

Any thoughts?

To stop anyone with a Group Discount from using a Discount Coupon, you could alter the ot_coupon.php module with something like:

  function credit_selection() {
    global $discount_coupon;
    // note the placement of the redeem code can be moved within the array on the instructions or the title

    // bof: stop discount coupon for anyone in a customer group
    global $db;
    $chk_group = $db->Execute("select customers_group_pricing from " . TABLE_CUSTOMERS . " where customers_id = '" . $_SESSION['customer_id'] . "'");
    if ($chk_group->fields['customers_group_pricing'] > 0) {
      $allow_discount = false;
    } else {
      $allow_discount = true;
    }

    if ($allow_discount) {
    $selection = array('id' => $this->code,
                       'module' => $this->title,
                       'redeem_instructions' => MODULE_ORDER_TOTAL_COUPON_REDEEM_INSTRUCTIONS . ($discount_coupon->fields['coupon_code'] != '' ? MODULE_ORDER_TOTAL_COUPON_REMOVE_INSTRUCTIONS : '') . ($discount_coupon->fields['coupon_code'] != '' ? MODULE_ORDER_TOTAL_COUPON_TEXT_CURRENT_CODE . '<a href="javascript:couponpopupWindow(\'' . zen_href_link(FILENAME_POPUP_COUPON_HELP, 'cID=' . $_SESSION['cc_id']) . '\')">' . $discount_coupon->fields['coupon_code'] . '</a><br /><br />' : ''),
                       'fields' => array(array('title' => MODULE_ORDER_TOTAL_COUPON_TEXT_ENTER_CODE,
                                               'field' => zen_draw_input_field('dc_redeem_code', '', 'id="disc-' . $this->code . '" onkeyup="submitFunction(0,0)"'),
                                               'tag' => 'disc-'.$this->code
                       )));
    }
    // eof: stop discount coupon for anyone in a customer group

    return $selection;
  }

Note: you should include some type of exclusion statement in your Discount Coupons ...

Much appreciated Ajeh. I'll give that a whirl.

When you say I should include an exclusion statement, are you referring to the printed/virtual coupon itself or are you refering to code exclusion?

Just a notice such as Discount Coupons not valid with other discounts or something so people do not wonder ...

Hi, I was wondering if I could somehow apply this idea to a coupon I am preparing for a trade show. I want to offer a coupon to all first time users, but I do not want them to be able to use the coupon if they have made a purchase in the past. Let me say first that I am in NO WAY a good coder, so if you have an idea PLEASE explain it to me as if I were a 4 year old.

Thanks.
