Look for set_cart_discount_shipping and set_cart_free_shipping in the Big Chooser help file.

If you are using any of my discounting software (Better Together, Combination Discounts, Big Spender, Big Chooser, Quantity Discounts, Frequency Discounts, Military Discounts, Newsletter Discounts) along with the Zen Cart Sales Report mod, please be aware of the following issue.

Running Sales Report against an order with one of these discounts will cause the totals not to add up correctly.

The fix is to modify admin/includes/classes/sales_report.php  as follows:  search for

          elseif ($class == "ot_coupon" || $class == "ot_group_pricing" || $class == "ot_better_together") {

and add in the classes you are using.

For Quantity Discounts, this would be

$class == "ot_coupon" || $class == "ot_group_pricing" || $class == "ot_better_together" || $class == "ot_quantity_discount"

A complete list of the classes I have created that require this fix is:

• Better Together: “ot_better_together”
• Big Chooser: “ot_big_chooser”
• Big Spender: “ot_bigspender_discount”
• Combination Discounts: “ot_combination_discounts”
• Frequency Discounts: “ot_frequency_discount”
• Quantity Discounts:  “ot_quantity_discount”
• Newsletter Discounts: “ot_newsletter_discount”
• Military Discount: “ot_military_discount”

If you want a complete if clause that handles all of these plus the built in discounts (including GV), it would look like this:

elseif ($class == "ot_coupon" || $class == "ot_group_pricing" ||
                 $class == "ot_better_together" ||
                 $class == "ot_big_chooser" ||
                 $class == "ot_bigspender_discount" ||
                 $class == "ot_combination_discounts" ||
                 $class == "ot_frequency_discount" ||
                 $class == "ot_quantity_discount" ||
                 $class == "ot_newsletter_discount" ||
                 $class == "ot_military_discount"

The usual restrictions apply: the items in the discount must all be products without attributes.

One of the features which is required for Zen Cart PCI compliance is periodic password changes.  This can be a nuisance on test carts and carts on your local PC.  Here’s how to turn it off.

a) To disable forced 90 day password changes, edit

admin/login.php

and change

define('ADMIN_PASSWORD_EXPIRES_INTERVAL', strtotime('- 90 day'));

to

define('ADMIN_PASSWORD_EXPIRES_INTERVAL', strtotime('- 36500 day'));

(Note that the above change means you won’t have to change passwords for 100 years.  To require an annual password change, use the value 365 instead.)

b) To disable the check against the last 3 passwords, edit

admin/includes/functions/admin_access.php

and change zen_check_for_password_problems() so that the first line is

return FALSE;

To increase the Admin Timeout value to 1800 seconds (30 minutes), go to Admin->Tools->Install SQL patches, and paste the following into the “Enter the query to be executed” box:

UPDATE configuration SET
configuration_value = '1800',
set_function = 'zen_cfg_select_option(array(\'1800\', \'900\', \'600\', \'300\'), '
WHERE configuration_key = 'SESSION_TIMEOUT_ADMIN';

To change it back, go to  Admin->Configuration->My Store, and set the
Admin Session Time Out in Seconds value back to 900.

To use a value other than 30 minutes, just change the two “1800″ numbers above to a number of seconds of your choosing (above 900).

Then modify /includes/functions/sessions.php as follows:

a) Find the block that looks like this:

if (!$SESS_LIFE = (SESSION_TIMEOUT_ADMIN > 900 ? 900 : SESSION_TIMEOUT_ADMIN)) {
$SESS_LIFE = (SESSION_TIMEOUT_ADMIN > 900 ? 900 : SESSION_TIMEOUT_ADMIN);
}

and change it to this:

$SESS_LIFE = SESSION_TIMEOUT_ADMIN;

b) Find the block that looks like this:

     
@ini_set('session.gc_maxlifetime', (SESSION_TIMEOUT_ADMIN > 900 ? 900 : SESSION_TIMEOUT_ADMIN));

and change it to this:

     
@ini_set('session.gc_maxlifetime', SESSION_TIMEOUT_ADMIN);
