Seperate Pricing Per Customer v3.5

Recommended Posts

Im running SPC 4.15 and so far are quite happy with it untill faced following probz:

 

http://www.???.??/catalog/index.php?cPath=...mp;filter_id=25

 

select count(p.products_id) as total from (products p, products_description pd, manufacturers m, products_to_categories p2c) left join specials_retail_prices s using(products_id) where p.products_status = '1' and p.manufacturers_id = m.manufacturers_id and m.manufacturers_id = '25' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '4' and p2c.categories_id = '36'

 

I really can't get clear WHICH part of the code performing it... therefore can't get clear.

 

Any suggestions and/or assistance?

Of course it would be helpful to tell which error you get... I presume it has to do with MySQL5 and those fixes on index.php can be found in the latest version of SPPC. You would also need to fix advanced_search_results.php.

I just finished installing this mod in a VERY HEAVILY modified store and I am thrilled to say everything is working! (so far!) I wand to thank the contributors who wrote this... It is the most elaborate mod I've used and so well done.. you should get a prize or award or something! Anyway I did want to share one problem I had and it's solution in case anyone else has it...

 

I was getting a Fatal Error: Call to a member function calculate_price() on a non-object in my shopping_cart.php file. I looked through the forum and the only lead was to look at the includes/classes/currencies.php file to make sure it was the current version.. and it is. So I was stumped. I then found this, posted by Draeisme in a different forum -

 

"Hey, i had the same problem. I fixed it by making a change. The currencies variable has to be defined earlier in the code.

 

Find this code below

CODE

function calculate() {

global $customer_id, $sendto, $ship_zip;

 

 

Change it to

 

CODE

function calculate() {

global $currencies, $customer_id, $sendto, $ship_zip;"

 

It solved my problem! I only had the

 

function calculate() {

 

part of the code but I added the rest as suggested and it worked! Hopefully it will help someone else, too!

 

Cheers!

Upsss.... Sorry not to mention it since beginning :blush:

 

index.php?cPath=29_31_36&sort=3a&filter_id=23

 

1052 - Column 'products_id' in from clause is ambiguous

 

select count(p.products_id) as total from (products p, products_description pd, manufacturers m, products_to_categories p2c) left join specials_retail_prices s using(products_id) where p.products_status = '1' and p.manufacturers_id = m.manufacturers_id and m.manufacturers_id = '23' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '4' and p2c.categories_id = '36'

 

You're correct that I'm running under MySQL - 5.0.27

Version 2 of the Quantity Price Breaks Per Product for Separate Pricing Per Customer contribution has been uploaded now. It's an enhanced implementation of QPBPP 1.3.5 for SPPC 4.2.2.

A minimum order quantity (different for groups of course) has been implemented (using parts of other contributions).

Improvements on the admin side were made and the display of the price breaks on product_info.php can now be changed to a dropdrown (triggered by a setting in the admin [Configuration->Price breaks] using the number of price breaks for a product.)

You need to have at least MySQL 4.1 to be able to use this addon because of the use of subselects.

Hello,

 

I have posted this on the Order Editor contribution forum but thought that some here in the SPPC forum might have a clue how to get this fixed...

 

My question relates to Order Editor working along with SPPC. It seems to work fine except for when I try to add a product. The price next to the product in the dropdown is only reflecting the set "retail" price and not the SPPC price according to the customers group. Is there a workaround for this?

 

If this has been mentioned elsewhere I apologize... perhaps a kick in the right direction?

 

Thanks.

 

 

To make it more clear, when I add a product in the order editor the price defaults to retail regardless of the customer group. Is there a way to reflect the special pricing in this dropdown? It's important to mention that although the incorrect price shows in the dropdown when I add the product the correct price for the customer group is calculated in the order.

 

Thanks again.

Never seen that contribution but if it can get the price from the table products then surely it can look for a price in products_groups too. Just need to find the right place for the code :)

Just need to find the right place for the code :)

 

That's the hard part... I have narrowed the code down to the following sections. The first is where, I believe, the information is being pulled from the db:

 

$products_query = tep_db_query("select distinct p.products_id, p.products_price, p.products_model, pd.products_name from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_CATEGORIES . " c, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c " . $product_search . " order by pd.products_name");
$not_found = ((tep_db_num_rows($products_query)) ? false : true);
 }

 $category_array = array(array('id' => '', 'text' => TEXT_SELECT_CATEGORY),
					  array('id' => '0', 'text' => TEXT_ALL_CATEGORIES));

 

This second bit is what is being displayed in the dropdown:

 

if (($step > 1) && (!$not_found)) {
$product_array = array(array('id' => 0, 'text' => TEXT_SELECT_PRODUCT));
while($products = tep_db_fetch_array($products_query)) {
  $product_array[] = array('id' => $products['products_id'],
						   'text' => $products['products_name'] . ' (' . $products['products_model'] . ')' . ': ' . $currencies->format($products['products_price'], true, $order->info['currency'], $order->info['currency_value']));
}
 }

 

Do you have any ideas as to what I could modify to show the correct price? I tried to modify it a bit but bad things happen when i do that :)

 

Thanks

I have just added this contrib, seems to be a problem, as soon as you try to go to your cart contents it just shows a blank screen. I have tried both a manual install and replacing the files with the modded ones included.

Any ideas?

Yes, find out what the error is. Ask your hosting provider if and where they keep an error log. Without error message it could be anything.

}

that it could work.

that it could work.

 

 

Thanks Jan. I tried that code but received an error:

 

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /homepages/28/d244355237/htdocs/temp/admin/includes/functions/database.php on line 99

 

I looked at this file and at line 99 is the following function (line 99 is bold):

 

function tep_db_fetch_array($db_query) {

return mysql_fetch_array($db_query, MYSQL_ASSOC);

}

 

Any other suggestions? I've been trying to play with the code for the last few days and I must say that although I'm not getting anything to work I am learning a lot about PHP and what not to do... ;)

 

Thanks again Jan.

That's a very generic error. I think this should be changed to:

$cg_id_query = tep_db_query("select customers_group_id from orders, customers where orders.customers_id = customers.customers_id and orders.orders_id = '" . (int)$_GET['oId'] . "'");

Ok, I have tried installing this on a new install, using the modified files included in the addon.

For some reason I'm unable to create a customer account, I get this message

 

1146 - Table 'awdcifc_osc1.TABLE_CUSTOMERS_GROUPS' doesn't exist

 

select c.customers_group_id, cg.customers_group_show_tax, cg.customers_group_tax_exempt, cg.group_specific_taxes_exempt from customers c left join TABLE_CUSTOMERS_GROUPS cg using(customers_group_id) where c.customers_id = '2'

 

[TEP STOP]

 

Any ideas?

Is this a code problem, or a database problem, I'm fairly new to this and am worried I'm gonna make a mess if I try to fix this myself.

You didn't add that define to one of the two includes/database_tables.php files.

I know this is a stupid question, but how and where do I add the code? And what code? Will I have to fully re-install?

And have you checked those to see if they contain those defines for SPPC? People do make simple mistakes, backups get reloaded, FTP transfers not succesfull etcetera.

Jan, that did eliminate the error I was receiving however it still does not accurately show the group price in the dropdown. I think that I might abandon this mission just because I don't know enough to make it work and I know you have much more important endeavors to deal with. I don't want you to feel like it is a problem that you need to fix.

 

I really appreciate you taking the time to work with me on this Jan and if you do have any other ideas to offer I will be more than willing to try them but otherwise I'll just have to try to tackle this when my skills develop a bit more.

 

Thanks again for all of your effort.

if you do have any other ideas to offer

There are two occurrences of $product_query in the file edit_orders_add_product.php (I think you are using that). Maybe it is using the first one. Try making an obvious error in the $product_query like changing products_id in products___id and if that query is used you will see an error. If it uses another one, you don't get an error :)

 

If so, then move the query and code for getting the $customer_group_id higher (to above the first occurence of $product_query) and adapt the first query likewise as the second one.

Hi

 

I have installed SPPC 4.2.2 on a clean 2.2RC2a on a separate local site just to give it a good play about, with a view to doing a manual install on my shop.

 

I'm loving it so far and i would like to ask about when corporate customers registering for 'trade' with a Company's Tax ID no...

 

I would like to know if it's possible to validate the Tax ID no immediately, so that the customer would immediately become a 'trade' customer?

 

For instance, validating the Tax No format and performing a remote look up to verify that the Tax ID is currently in use by a real company?

 

I have been trying to modify GCDiscountSpecials 1.4b so that the customer could opt for a trade account at the create account stage. I've managed to implement the relevant entry & database updates but alas, not the validation of the company so it's not really a goer as yet.

 

Then I found this contrib and would like to try the same idea with this. Maybe others would too?

 

Any ideas would be greatly appreciated

 

Bee

:)

That is a contribution in itself since there is no uniform tax number format all over the world and a remote lookup will undoubtedly not be possible everywhere also. I think there was something for the EU (TVA Intracommunautaire v2.0, 1590 and/or E.U. VAT Intracom Number, 1848) but I'm not sure how those contributions work and how fast.

Hi Jan.

 

I am once again in need of your assistance. I've loaded price breaks for sppc and I have hide products also installed. My current problem is with the includes/classes/shopping_cart.php. When I try to bring up the store I get this error.

 

Parse error: syntax error, unexpected T_CLASS, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /mnt/blablablabla/catalog/includes/classes/shopping_cart.php on line 714

 

The admin side seems to work perfectly. If I delete the code for hide products then the store comes up without an issue. However when I add a product to the cart it automatically adds 2 items.

 

Please help!!!!

 

Code with hide products installed that give parse error
