Installation Instructions:
- Back up everything! Try this in a test environment prior to installing
it on a live shop.
- Copy the contents of the unzipped folder to the root directory of your
shop.
- Login to admin and in Modules->Order Total you will see 'Newsletter Discount' listed along with all the other modules available.
- Click on 'Newsletter Discount' to highlight the module and click on 'Install'
- Set the parameters according to your discounting plan.
- If you wish, follow the guidelines in marketing
to advertise your discounts.
Configuration:
Some shops will want to further customize their discounting policy.
User exits are provided to permit the following customizations:
- Include or exclude certain categories from discounting.
- Include or exclude certain products from discounting.
Specifically:
- The function exclude_category() shows you how to add categories to
a list of categories to not be discounted.
- The function exclude_product() shows you how to add products to
a list of products to not be discounted.
Each of these functions contains a simple example of how to use it using
item and category numbers like 99999, 99998, etc. Note that the "category"
of an item is its parent category; see
my category explanation page
for an explanation. Note that to use the category exclusions you must
be running Zen Cart 1.3.5 or greater.
The user exits are in includes/modules/order_total/ot_newsletter_discount.php.
MailChimp
MailChimp is an Email Service Provider; their business is managing
commercial email. They have a very reasonable per-email cost
model (unlike firms like Constant Contact, which charge per month
irrespective of how little mail you send).
You can integrate MailChimp into your Zen Cart using the
MailChimp Newsletter contribution.
The Newsletter Discount contribution uses the
MailChimp API to
communicate with MailChimp and determine whether the
customer is a newsletter subscriber.
Configuration of Newsletter Discounts when using MailChimp:
Marketing
A discounting plan reaches maximum effectiveness through advertising.
Customize the tpl_product_info_display.php file to advertise
your discounts. Put the file
includes/templates/template_default/templates/tpl_product_info_display.php
into includes/templates/<Your Template>/templates, and add this block
of code to the page:
<?php
$value = "ot_newsletter_discount.php";
include_once(zen_get_file_directory(DIR_WS_LANGUAGES . $_SESSION['language'] .
'/modules/order_total/', $value, 'false'));
include_once(DIR_WS_MODULES . "order_total/" . $value);
$discount = new ot_newsletter_discount();
echo '<div class="content" id="discountPolicy">';
$resp = $discount->get_html_policy();
echo $resp;
echo '</div>';
echo '<br class="clearBoth" />';
?>
The placement of this code is a matter of personal preference;
try placing it below the product description and adjust to your tastes.
You can put this code whereever you'd like. For example, here I have
placed it in tpl_modules_create_account.php so that new signups see the policy
when making their newsletter choice:
Files
(new)includes/languages/english/modules/order_total/ot_newsletter_discount.php
(new)includes/modules/order_total/ot_newsletter_discount.php
(new)includes/classes/MCAPI.class.php
