Want to know how much was 'saved' by your customers by using a discount coupon? Here is a mod for v1.38 that will add it in the Admin coupon report. Enjoy :)
in admin/coupon_admin.php change lines 455+ to the following, adding the two statements marked "START MOD" and "END MOD"
<?php $heading = array(); $contents = array(); $coupon_desc = $db->Execute("select coupon_name from " . TABLE_COUPONS_DESCRIPTION . " where coupon_id = '" . $_GET['cid'] . "' and language_id = '" . $_SESSION['languages_id'] . "'"); $count_customers = $db->Execute("select * from " . TABLE_COUPON_REDEEM_TRACK . " where coupon_id = '" . $_GET['cid'] . "' and customer_id = '" . $cInfo->customer_id . "'"); // START MOD $coupon_saved = $db->Execute("SELECT sum(value) as saved FROM " . TABLE_COUPON_REDEEM_TRACK . ", " . TABLE_ORDERS_TOTAL . " WHERE coupon_id = " . $_GET['cid'] . " AND orders_id = order_id AND class = 'ot_coupon'"); // END MOD $heading[] = array('text' => '<b>[' . $_GET['cid'] . ']' . COUPON_NAME . ' ' . $coupon_desc->fields['coupon_name'] . '</b>'); $contents[] = array('text' => '<b>' . TEXT_REDEMPTIONS . '</b>'); // $contents[] = array('text' => TEXT_REDEMPTIONS_TOTAL . '=' . $cc_list->RecordCount()); $contents[] = array('text' => TEXT_REDEMPTIONS_TOTAL . '=' . $cc_query_numrows); $contents[] = array('text' => TEXT_REDEMPTIONS_CUSTOMER . '=' . $count_customers->RecordCount()); // START MOD $contents[] = array('text' => TEXT_REDEMPTIONS_SAVED . '=' . $coupon_saved->fields['saved']); // END MOD $contents[] = array('text' => ''); ?>
