After downloading the file just include the files in your project as they are given in the folder structure you downloaded the file.

In zen cart that is default that you can create admin coupon to give amount deduction or free shipping ,
you can not give customer both benefit of amount deduction as well as free shipping,

to do that you have to add code in two files that are

1) includes/modules/order_total/ot_coupon.php
2) includes/templates/[your template]/popup_coupon_help/tpl_main_page.php

In file 1 ot_coupon.php

find the code as


if ($od_amount['type'] == 'S') $order->info['shipping_cost'] = 0;
$order->info['total'] = $order->info['total'] - $od_amount['total'];
if (DISPLAY_PRICE_WITH_TAX == 'true') {
$od_amount['total'] += $tax;
}
if ($this->calculate_tax == "Standard") $order->info['total'] -= $tax;
if ($order->info['total'] < 0) $order->info['total'] = 0;
$order->info['tax'] = $order->info['tax'] - $tax;
$this->output[] = array('title' => $this->title . ': ' . $this->coupon_code . ' :',
'text' => '-' . $currencies->format($od_amount['total']),
'value' => $od_amount['total']);


replace it with


if ($od_amount['type'] == 'S') $order->info['shipping_cost'] = 0;
// harry
if ($od_amount['type'] == 'S' && is_numeric($od_amount['coupon_amount']) )
{
$order->info['total'] = $order->info['total'] - $od_amount['coupon_amount'];
}
$order->info['total'] = $order->info['total'] - $od_amount['total'];
if (DISPLAY_PRICE_WITH_TAX != 'true') {
$order->info['total'] -= $tax;
}
$order->info['tax'] = $order->info['tax'] - $tax;
// if ($this->calculate_tax == "Standard") $order->info['total'] -= $tax;
if ($order->info['total'] < 0) $order->info['total'] = 0;
$this->output[] = array('title' => $this->title . ': ' . $this->coupon_code . ' :',
'text' => '-' . $currencies->format($od_amount['total']+$od_amount['coupon_amount']),
'value' => $od_amount['total']+$od_amount['coupon_amount']);


find

if (isset($_SESSION['shipping_tax_description']) && $_SESSION['shipping_tax_description'] != '') {
$od_amount['tax_groups'][$_SESSION['shipping_tax_description']] = $od_amount['tax'];
}
return $od_amount;


replace it with

if (isset($_SESSION['shipping_tax_description']) && $_SESSION['shipping_tax_description'] != '') {
$od_amount['tax_groups'][$_SESSION['shipping_tax_description']] = $od_amount['tax'];
}
// harry
$od_amount['coupon_amount'] = $coupon->fields['coupon_amount'];
return $od_amount;


and in file 2 tpl_main_page.php

find

case 'S':
$text_coupon_help .= TEXT_COUPON_HELP_FREESHIP;


replace it with

case 'S':
if ( is_numeric($coupon->fields['coupon_amount']) )
{
$text_coupon_help .= sprintf(TEXT_COUPON_HELP_FIXED, $currencies->format($coupon->fields['coupon_amount']));
}
$text_coupon_help .= TEXT_COUPON_HELP_FREESHIP;


and its done…….

To add the banners in the zencart just follow the three steps.

1. Open the zencart database and insert one record in the “Configurations” table.

1. Keep the configuration_id null(it will update automatically)
2. Write the title for e.g.’Banner Display Group All pages left‘ in configuration_title.Layout Settings on the Admin side.
3. In configuration_key write the tag ‘SHOW_BANNERS_GROUP_SET10‘

   Note: SET10 is the id of sets of banner. Upto SET9 all are the default banners of zencart.Update the SET no. everytime you want to add banners such as SHOW_BANNERS_GROUP_SET11,SHOW_BANNERS_GROUP_SET12 and so on….

4. In the configuration_value write any value such as’left_banner2‘

   Note : This value will be the group name of your banner and it will be added in the dropdown list of the banner groups when you will add the new banner from admin.

5. Add any description in “configuration_description” field.
6. Just write ‘19‘ in the “configuration_group_id” as 19 is the id for the banners.
7. Just give the unique id for the “sort_order field” for the group_id 19.Generally start after id 75.The value must increment every time you add the new banners.
8. Keep all other fields as it as and save the record.

2. On the admin side click on new banner button in the Banner Manager.

1. Give the title for the banner such as New Banner.
2. Give the url in url box if you want to add such as http://www.google.com
3. Now select the group from the dropdown box.Your newly created group will be added there. Select it.
4. Upload the image you want to display as banner and click on insert.

Your banner has been created now.

3. To display the banner in the site just copy the following code and paste it where you want to display the banner.

 <?php
  if (SHOW_BANNERS_GROUP_SET10 != '' && $banner = zen_banner_exists('dynamic', SHOW_BANNERS_GROUP_SET10)) {
if ($banner->RecordCount() > 0) {
echo zen_display_banner('static', $banner);
    }
  }
?>

That’s it.You can see the banner now. I hope it works.

some has experienced that when clicked on some link blank page is displayed

that problem is there because of add page process of zencart

to add page in zencart we have to create four pages

* A new directory, includes/modules/pages/myNewPage/, containing a file called header_php.php

* A new file in the directory includes/templates/template_default/templates called tpl_myNewPage_default.php

* A new file, includes/extra_datafiles/myNewPage.php, defining your new page’s filename for the Zen Cart™ system

* A new language file, includes/languages/english/myNewPage.php

there is problem in includes/extra_datafiles/myNewPage.php

so dont add file in that folder may your problem solved ! ! !
