Hi,

I'm about to install Dual Pricing on zen cart store to have one group of retail customers and one group of wholesalers with different product prices..

The problem is that I'd like to offer only some shipping options and payments options to wholesalers.
In this thread https://www.zen-cart.com/showthread.php?214123-Dual-Pricing-V1-8-separate-shipping-rates-for-wholesale-retail-other-questions

I see that you have an add-on for table shipping module.
I'd like to modify other modules (and payment modules) adding to them some code to run a check at the beginning based on the fact that $_SESSION['customer_whole'] is 0 for customers and 1 for wholesalers in Dual Pricing.

The problem is that I'd not know how to set that check.
Could you please help me with the code?

Thank you very much,
PM_SENDER

The way I would do this would be to modify the includes/modules/payment/ or includes/modules/shipping/ files.

I'll use money order payment method for the example:

Change something like:

$this->enabled = ((MODULE_PAYMENT_MONEYORDER_STATUS == 'True') ? true : false);

if enabling for wholesale customers ONLY:

$this->enabled = ((MODULE_PAYMENT_MONEYORDER_STATUS == 'True' && $_SESSION['customer_whole'] == 1) ? true : false);

or for retail ONLY:

$this->enabled = ((MODULE_PAYMENT_MONEYORDER_STATUS == 'True' && $_SESSION['customer_whole'] != 1) ? true : false);

NOTE how it is != 1 versus == 0

Hi, thank you very much for your help!
I'm having some issues implementing your solution with freeoptions shipping module.

In fact, if I change the PHP code:

if (zen_get_shipping_enabled($this->code)) {
          $this->enabled = ((MODULE_SHIPPING_FREEOPTIONS_STATUS == 'True') ? true : false);

to this:

      if (zen_get_shipping_enabled($this->code)) {
          $this->enabled = ((MODULE_SHIPPING_FREEOPTIONS_STATUS == 'True' && $_SESSION['customer_whole'] != 1) ? true : false);

Thoe module is never displayed to any type of customer and in addition, it is not showed in the admin>modules>shipping
What is wrong?

Thank you

Hi, I fixed it moving position of the statement. Thank you.

Hi,

I'd like to set a minimum order value to proceed checkout (let's say $200) only for wholesaler, not for regular customers.
I think that your code already used for shipping methods would be a starting point for this.

Do you have any idea of the code and where to put it?
The need is to either don't show any checkout button or whatever is easier to wholesalers whose order is less than $200.

Thank you very much for your help.

You can use this module and then modify for wholesale

Thank you. How should I modify the code of the module to have it applying the minimum order condition only to wholesale?

Thanks again for all.

Change lines like these:

if ($_SESSION['cart']->count_contents() > 0 && MIN_FIRST_ORDER_AMOUNT > 0) {

to

if ($_SESSION['cart']->count_contents() > 0 && MIN_FIRST_ORDER_AMOUNT > 0 && $_SESSION['customer_whole'] == 1) {

and

if($_SESSION['cart']->show_total() < MIN_FIRST_ORDER_AMOUNT) {

to

if($_SESSION['cart']->show_total() < MIN_FIRST_ORDER_AMOUNT && $_SESSION['customer_whole'] == 1) {

That should only flag orders that are wholesale... where $_SESSION['customer_whole'] == 1
