Minimum order for wholesale customers only.

I am using the "Dual Pricing - Wholesale Pricing" module and want to set up a minimum order amount that only applies to customers in a wholesale group.

I installed the Minimum Order contribution and it's working prefectly, now I just need to figure out how to exclude non wholesale customers.

My thought was that this could be accomplished by editing the class.minimum_order_amount.php file and adding another if statement related to the customers wholesale group, but I can't seem to get it working.

Any help would be appreciated.

Does anyone have any suggestions for me?

I am interested in this information also.

Thanks!

I am interested too. Please help!

There is an add-on for Minimum Order in the Downloads ...

You could modify that with your wholesale identifier so that only those customers are looked at for this minimum order module ...

Can anyone explain how to do this? Thanks!!!

How are you identifying wholesale from retail customers?

I was hoping to use the minimum order mod on my wholesale group pricing only. Can this be accomplished?

Replace your includes/classes/observers/class.minimum_order_amount.php
With the above code. Use this ONLY if you have Dual Pricing - Wholesale Pricing installed.

ok, I have a totally separate wholesale site. Is there a way to set up a minimum order there? would that mod work?

Yes, it would. But use it normally, of course, without the above edit.

Roger that. Thanks!!!!:clap:

I was just noticing this post, Marg, that looks great.

My particular issue is I'm using Group Pricing instead of Dual Pricing. Is there a way to modify this sheet to do it for only the Group Pricing?


Thanks very much in advance...

I must have missed the email for this post. Did you find your answer, pensive?

Hi Marg,

Nope not yet... but still working on it.

Ill keep you posted if I get it right..!

Take care...

This code doesn't work. First I copy and pasted it all and it makes a blank page show up after pressing checkout. So then I just copied the lines thath ave 'customers_whole' in it. The blank page doesn't show up any more, but the minimum order no longer works. Do you have a solution?
http://www.fragrantrainsoap.com/store/

This is for 1.3.8a Zen Cart
If that's what you are using then use this:
http://www.zen-cart.com/forum/showthread.php?t=84613
To debug an dput your error here..

[21-May-2008 14:42:27] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/fragra5/public_html/store/includes/classes/observers/class.minimum_order_amount.php:61) in /home/fragra5/public_html/store/includes/functions/functions_general.php on line 44

You're welcome :c)
What is on the line 61:
home/fragra5/public_html/store/includes/classes/observers/class.minimum_order_amount.php:61
Cut and paste... There will be the issue
That simple

It was just the closing tag: ?>
But I think there was something hidden, because I copy over the old code for the bottom and now it's fine... There's no white screen after pressing checkout... but it also doesn't have the minimum order acvitavted anymore. It's letting me checkout.

What's on the line 44 in /home/fragra5/public_html/store/includes/functions/functions_general.php?

header('Location: ' . $url);

Is it possible there was a line break at the end of the file? After the closing php tag?

In the functions file or class.minimum_order_amount.php?

class.minimum_order_amount.php

Nope. And I know I'm logged in as a whole account because I can see both prices. See attached. But it's letting me check out. And I have the minimum set to $200.

I thought you had said you replaced the file with the older one... What older one file? The one that came with minimum_order?

It's the one you added to.

Hm... So for certain, line 50 look like this?
if ($_SESSION['cart']->count_contents() > 0 && $_SESSION['customers_whole'] ==1 && MIN_ORDER_AMOUNT > 0) {

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

Did minimum_order work prior to trying to use this file?

Yes. The message pops up on the shopping cart page for everyone.

This code is incomplete... do not use the file I stated on this topic, it will not work. I am working on getting a formal contribution addition together...
Marg

Is there a working version available yet? I can't wait to see it working

Hi, i just discovered this thread.GREAT!!:clap::clap:

Great work again Marg :clap::clap::clap::clap:
Best regards, Zoli.

It's me again.As i sayd it works for me.
I think that this only works if you have the latest version of DualPrice(i have it) beacuse it relies on $_SESSION['customers_whole'] defined in /includes/modules/pages/login/header.php

Or you could do the follwing:
-create a new table in the database customers callled customers_morder (or what you want)
-edit /includes/modules/pages/login/header.php and the following
arround line 48 add customers_morder before FROM " . TABLE_CUSTOMERS . " WHERE customers_email_address = :emailAddress";

PHP Code:

---

$check_customer_query = "SELECT customers_id, customers_firstname, customers_lastname, customers_password, customers_email_address, customers_default_address_id, customers_authorization, customers_referral, customers_whole, customers_morder 
FROM " . TABLE_CUSTOMERS . " WHERE customers_email_address = :emailAddress"; 


---

-arround line 90 after $_SESSION['customer_whole'] = $check_customer->fields['customers_whole']; add $_SESSION['customer_morder'] = $check_customer->fields['customers_morder'];

PHP Code:

---

$_SESSION['customer_whole'] = $check_customer->fields['customers_whole']; 

$_SESSION['customer_morder'] = $check_customer->fields['customers_morder']; 


---

-change in /includes/classes/observers/class.minimum_order_amount.php (in 2 places) $_SESSION['customers_whole'] to $_SESSION['customers_morder']
- thats all, maybe you want control this over the admin for each customer, thats also possibel.

If you want to use this feature only for wholeslae customers i suggest to upgrade your DualPricing version.
Hope this is helpfull to some one.
Best regards Zoli.

Hello, this mod is not working for me at all. Not for retail nor for wholesale.

I'm using the latest version of dual pricing and simple checkout.... any ideas on how to make this work??

Thank you in advance

One more thing, would it possible to have a field in the admin - customers area to manually enter the minimum amount order?
I have two sets of wholesale customers and with one I need a minimum amount order but not with the other.
I'm pretty sure there are others in my ame situation who would benefit tremendously by this mod.

Thank you!

mvstudio -

I have been :frusty: this for some time now and look to have figured out a solution. So far this is working on my test site. I am by no means a programmer so it may not be the cleanest.

Feedback is always welcome.

Nicely done. Works like a charm.

I'm afraid with the latest version of Dual Pricing this change is not working. Minimum order amount is being ignored completely and checkout is allowed regardless of order amount.

Is there any way to make it only work with one set of wholesale customers, I have 4 wholesale groups and only need it on 1???

I am looking for some assistance with my website. www.flyfishingsigns.com .


In particular, I am looking for somebody who is familiar with this Wholesale Mod.

http://www.zen-cart.com/index.php?ma...roducts_id=166

I would like to utilize this site as retail and wholesale. The site works as retail until the order reaches $200. I would like to have a box in the check-out page of the site say “Attention Wholesale Customes: Once the $ total amount of your order reaches $200, these retail prices will automatically change the wholesale prices.” How do I make sure that the wholesale buyer purchases the $200 minimum order?

If you are not familiar with this mod or would like to suggest somebody who is more familiar and comfortable with this install, please forward their contact information.

Thanks,

Erik I. Pieper

Correcting my last post. The latest works, but it throws a blank checkout_shopping.php page. Any ideas?

This code is only for:
Minimum Amount for Wholesale Customers with Dual Pricing Module After Bug Fix Only.
Bug fix for Dual Pricing Module at page #69 http://www.zen-cart.com/forum/showth...=35450&page=69

After the bug fix, replace the code in this file:
/includes/classes/observers/class.minimum_order_amount.php
With this code:

*Note: Thanks to Marg http://www.zen-cart.com/forum/showthread.php?t=91542 for the code, i just changed "customers_whole" to "customers_wholesale" to make it work with the Dual Pricing Bug fix.

Goodluck.:bigups:

In addition to the previous post:
If you want to allow a few wholesale customers to purchase from your site with no minimum amount.

Go to admin controls>Customer>customer>edit which ever customer you want to allow buy wholesale without minimums and change their "Wholesale pricing level" to 2 instead of 1.

Assuming you've only set 1 level of wholesale pricing.
- 0 Automatic retail pricing for retail customers only.
- 1 This level is for wholesale customers with a minimum amount that you set.
- 2 This level is for wholesale customers with NO minimum amount.

Note* This is only for Minimum Amount for Wholesale Customers with Dual Pricing Module After Bug Fix Only.
Bug fix for Dual Pricing Module at page #69 http://www.zen-cart.com/forum/showth...=35450&page=69

Goodluch Zenning. :smile:

thank you for the update on this. I made the changes and like you say it works for wholesale customers level 1. Is there any way to make it work for customers wholesale level 2 and 3? We have minimum order amounts on each level. It would be nice if this could be applied to other wholesale levels as well.

Work for me too. Is there anyway to change it to minimum quantity per product?

Has anyone got this wholesale minimum order to work alongside the minimum order for retail?

I am needing both wholesale and retail minimum first orders and minimum orders after that.

Does anyone have any suggestions? :unsure:

Just to chime in and hopefully help someone else on the thread; the best way is to use 'not equal to' instead, so you can catch all the higher level of wholesale customers too (not just the 1st level). Also notice singular 'customer_whole' (that may be different depending on your Dual Pricing version).

Code:

---

if ($_SESSION['cart']->count_contents() > 0 && $_SESSION['customer_whole'] != 0 && MIN_ORDER_AMOUNT > 0)

Hello,
I am reading this post and I have installed the php as suggested. I now have box in my product box a product quantity add minimum unit mix yes or no. I have yes on and I have in wholesale prices the price. I have tried all the boxes relating to product min amount etc. In the main web (retail) the box shows in the catalog either with 1 if I set 1 or 5 if I set 5 to these figures. How do I work this script should I have to change something in the script?
Any help is greatly appreciated as I just can't figure it out.
Thanks
Ron

Hi Ron,

Please let us know the following to help you troubleshoot:
- A link to your store

I can't seem to find a product with multiple prices/attributes, or a minimum order amount in the cart. Can you provide a link directly to an affected product, and explain exactly what you would like it to do?

Here is the link

You will need to login use my login "stuffwholesale###################### pass 6KAN95k" This is my wholesale account level in dual pricing. You will see that the minimum quantity is on both pages 5 I want it to be 1 on the retail page then when you log in wholesale you would get your appropriate pricing but have to order the minimum of 5. Thanks for your help.

Ah, I see what you mean now. There is no built-in functionality to Dual Pricing or to the Minimum Order, to make wholesalers purchase a minimum quantity of a product. This Minimum Order applies to dollar amounts for the total order. I recommend you hire a skilled developer to build a Wholesale Minimum Quantity feature for you. Here's a link to the developer listings: http://www.zen-cart.com/forumdisplay...rt-Contractors

Thanks very much for your help, I have contacted a person, do you do this work?

Hi, Can anyone advise me please! www.ew-trading.com

Have today installed dual pricing as want to separate retail and wholesale sections - all fine. Installed Minimum order module and all ok but seems to be an issue with the auto_loaders/config.minimum_order_amount.php, was showing blank sceens and trial and error leaves me with this file removed so site can function, and as such, module isn't working... all other files ok but each time I try and load this I get blank screens. Any advice?? Using 1.3.9 zencart.

Thanks!
