Quantity Price Breaks

[Eim2]

Hello,

 

Is there anybody who has tried and succeeded to show retail prices along wholesale prices

in the product listing pages ( not product_info.php, that works great with Show list Prices),

when a SPPC wholesale customer is logged in.

 

I tried to get it to work by playing with the getPriceStringShort() function in the PriceFormatter.php

but retail prices just keep showing 0.00.

 

I guess the function are called differently in product_listing.php and in product_info.php but as

I m really not a very advanced php user,

 

Any hint would be much appreciated

I assume you use the Quantity Price Break version for SPPC? As far as I can remember the retail price is always available at first and is then replaced with the customer_group one. You could store it somewhere as a variabel retail_price that at first the same the products_price. You are probably best of by adding a separate function in PriceFormatter for getting that retail_price and then call that instead of getPriceStringShort().

Hello Jan,

 

I thought of that indeed but also that I could maybe ... use the variable that allready appears

throughout my Show Price List QPB version PriceFormatter.php as:

 

$this->listPrice = $prices['list_price'];

 

Really I have no clue why if I, for example, just change getPriceStringShort() to getPriceString()

in product_listing I cant get the retail price to show up.

 

As I said getPriceStringShort() is called differently in product_listsing.php than getPriceString()

in product_info.php.

 

Could you have a look at this file if you have time?

I thought of that indeed but also that I could maybe ... use the variable that allready appears

throughout my Show Price List QPB version PriceFormatter.php as:

 

$this->listPrice = $prices['list_price'];

 

Really I have no clue why if I, for example, just change getPriceStringShort() to getPriceString()

in product_listing I cant get the retail price to show up.

 

As I said getPriceStringShort() is called differently in product_listsing.php than getPriceString()

in product_info.php.

The code looks fine to me so I can't fathom why you shouldn't be able to use $this->listPrice in the function getPriceStringShort() (you don't show the use of it in the code you posted).

Hello everyone,

 

I just installed Quantity Price Breaks Per Product v1.3.6. But some of my osc files are old (2003 due to an old template).

 

Everything works good except the fact that TEXT_PRODUCTS_QTY doesn't appear on the product's file.(price for each and saving appear)

 

Does anyone have a solution?

 

Thanks

Hi,

 

I have just installed Quantity Price Breaks Per Product for Separate Pricing Per Customer v2.0. It works fine but with one big problem:

 

- I have 7 different customer groups and products with price breaks and without

 

If I have a product with price breaks and different prices for customer, the shop shows me the right prices on product listing page like new_products, search...

 

But if I have a product without price breaks but with different prices for customer, it shows me the price for the first customer group in product listing, regardless of the customer group. If I go to the product page it shows me the right price.

 

Any solution?

Everything works good except the fact that TEXT_PRODUCTS_QTY doesn't appear on the product's file.(price for each and saving appear)

Somewhere the define for that is missing. Try adding it to where price for each and saving are also defined.

I couldn't fathom why this would be happening but after some detective work I found that a query for the group prices doesn't return any results where there should be. I found that in e.g. includes/modules/product_listing it says in the query and customers_group_price !=null.

For some reason (I suppose this was working in the past, but I have upgraded MySQL to version 5 somewhere in time) this is not working properly. If I change it to and customers_group_price is not null it works again. I think more modules need adapting like the new products module on the front page.

 

The "is not null" is needed in the QPBPP version because there might be cases where you want to set quantity blocks etcetera for a group but not change the group price.

Hi Jan,

 

many thanks, this was the right solution. ;-)

hello,

 

i just installed QBC, and while i can get the price break to work for individual items (item A when they buy four, its 10 bucks) but i want them to be able to buy items a, b, c, d, and get those for four.

 

am i doing something wrong, the documentation says it should work, but im not getting it.

I have been installing this contribution and it almost works. The problem is that when adding a product to the cart you can enter any quantity regardless of the minimum of the bundle. When I define the bundle to be 22 and I add a product entering 12 in the quantity box it will add 12 instead of the nearest bundle amount of 22. However when updating the product (when there already is a quantity in the cart) it works like a charm and calculates the correct amount including the bundle quantity.

 

Anyone knows what the problem might be? I have been working on it for hours and it seems that the following line does not use the qpbpp qty of the product:

 

$this->contents[$products_id_string] = array('qty' => (int)$qty, 'discount_categories_id' => $product_info['discount_categories_id']);

 

This line, when updating the quanity of the cart does work:

 

$this->update_quantity($products_id_string, $qty, $attributes, $product_info['discount_categories_id']);

 

Help would be very much appreciated!

Well. Finally figured it out. For some reason the $qty was not calculated to the nearest products_qty_blocks in the adding to cart. Therefore I rewrote the script slightly. I already know it wasnt working because of another contribution because the contribution worked like a charm on a fresh installation but I have no idea which contribution caused this error.

 

Anyone with the same problems try in includes/classes/shopping_cart.php to change:

 

// BOF qpbpp
         if ($this->in_cart($products_id_string)) {
           $this->update_quantity($products_id_string, $qty, $attributes, $discount_category);
         } else {
           $this->contents[$products_id_string] = array('qty' => (int)$qty, 'discount_categories_id' => $discount_category);
// EOF qpbpp

 

into:

 

// BOF qpbpp
         if ($this->in_cart($products_id_string)) {
           $this->update_quantity($products_id_string, $qty, $attributes, $product_info['discount_categories_id']);
         } else {
// Berekening van aantal producten gaat niet goed zonder onderstaande code. Deze berekend de dichstbijzijnde minimale bundel afname bij het toevoegen van een product. Er word naar beneden afgerond.
$min_order_query = tep_db_query("select p.products_qty_blocks as min_quant FROM " . TABLE_PRODUCTS . " p where p.products_id = '".$products_id_string."'");
while ($min_order = tep_db_fetch_array($min_order_query))  
{
  if ($qty < $min_order['min_quant']) 
  {
	  $qty = $min_order['min_quant'];
  }
  if ($qty > $min_order['min_quant'])
  {	
	  $qty = ($qty - ($qty % $min_order['min_quant']));
  }
}

           $this->contents[$products_id_string] = array('qty' => (int)$qty, 'discount_categories_id' => $product_info['discount_categories_id']);
// EOF qpbpp

 

It will however round the final $qty down to the nearest products_qty_blocks rather then up. Math was not my best subject and I couldnt figure out how to do that.

Hello,

 

I am using the most recent version of QPBPP. We are selling DVD & CD duplications and would like customers to order a minimum amount which varies depending on the particular type of duplication offered. Once they satisfy the minimum they can order any quantity they want with no required block increment. The more they buy the better the discount. Here is a link to the shop. Right now the only items with the pricing included are the first 2 products in the DVDs category.

What I need are products with quantity based prices (volume discounts)

as well as most products will have options such as sizes and colors.

Not sure how all that is going to work out yet.

 

Right now with qpbpp I can add a "rule" which indicates the price will

be different for various quatities. This works. The quantity blocks works great.

 

When changing a product in admin I see a table showing price discounts

and the quantities at which they are effective. The problem is that this

table does not show up when viewing the product detail in product_info.php

I see only one price. I notice throughout the documentation that the

price discount table will appear on a product which has been configured

for quantity based pricing. I thought I was doing that when I set prices

and quantities on the edit product page.

 

Is there something wrong or am I just not doing something right?

The code looks fine to me so I can't fathom why you shouldn't be able to use $this->listPrice in the function getPriceStringShort() (you don't show the use of it in the code you posted).

 

Hello Jan,

 

First of all, thank you for all your support and Happy new Year too!

 

I was indeed very slow ... and forgot to say I did not use QBPP latest version,

but eventually found a way out, modified getPriceStringShort() and

called it differently in product_listing.php not using the PriceFormatter parse():

 

$pf->loadProduct($listing[$x]['products_id'], $languages_id);
           $lc_text = $pf->getPriceStringShort();

 

And this is the getPriceStringShort()

 

function getPriceStringShort() {

  global $currencies;

// BOF "Hide Price if $0 for "Quantity Price Breaks for SPPC 4.1.1" modification
if ($this->thePrice > 0 ) {
// EOF "Hide Price if $0 for "Quantity Price Breaks for SPPC 4.1.1" modification

       if($this->cg_id == 0) {

               if($this->hasQuantityPrice == true) {

       $lc_text = ' <span class="productSpecialPrice">' . STAFFEL_PRICE_AB . '</span>'
         . $currencies->display_price($this->lowPrice,
                                      tep_get_tax_rate($this->taxClass))

I hope not using the parse() does not affect the shop otherwise.

I was also asked to change the tax displays in some occurences but that is another subject.

 

Again many thanks and best regards

I finally found the problem!

In product_info.php the product_price variable is set to the

regular price or the quantity based price. Immediately following in

an IF/ELSE block. This sets the price variable to the special price

if one exists. If there is no special price then the ELSE clause

sets the price to what I believe is the regular price.

My solution was to comment out the else portion of the

IF/ELSE block. I've tested regular, special and quantity prices

and they all seem to work correctly.

 

// EOF qpbpp

 

if ($new_price = tep_get_products_special_price($product_info['products_id']))

{

$products_price = '<s>' . $currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id'])) . '</s>   <b class="productSpecialPrice">' . $currencies->display_price($new_price, tep_get_tax_rate($product_info['products_tax_class_id'])) . '</b>';

}

else

{

// $products_price = '<b class="productSpecialPrice">'.$currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id'])).'</b>';

}

 

 

The shopping cart already calculates the correct price.

Does anyone know why my store search results and product listings show nothing?

 

 

I followed the Manual installation instructions very carefully and I think I did everything right.

 

The product_info page and everything else works well.

 

 

Can anyone help me? What did I mess up on?

Edited January 9, 2010 by dOoBiX

[Jan Zonjee]

Does anyone know why my store search results and product listings show nothing?

Both use the module product_listing.php.

 

I followed the Manual installation instructions very carefully and I think I did everything right.

From the looks of it (button details) you are using a template. They often use non-standard osC code so adding QPBPP to it is different than for a standard osC listing module.

 

Do you really need to show the "price from" in your listings? You can leave out QPBPP from the product listing module and still have a good working price break.

[dOoBiX]

Thanks Jan Zonjee, I just changed my products_listing.php back to the original (from the template i bought) and it's working fine now!

[0ShippingZone]

I am trying to show 'Contact us' when the price is set to 0 or some value. I know this should be a quick change. Can someone point me to the right direction?

 

Ideally, link to the contact us page will be even better.

 

I found one contribution there which does that but it applies to older version of the QPB contribution only, not the new version.

[mylittlereddress]

Hi,

 

I have installed the contribution, which is working and I think it is great.

 

I am trying to change the format of the product_info page to move the Quantity Price Break table from the top of the page to below the product descriptions, above any featured products/other customers bought these product/etc boxes.

 

I have (what appears to be) successfully changed the price at the top of the page from the table to "From price" by changing

 

$pf->loadProduct((int)$_GET['products_id'], (int)$languages_id);

$products_price=$pf->getPriceString();

 

to

 

$pf->loadProduct((int)$_GET['products_id'], (int)$languages_id);

$products_price=$pf->getPriceStringShort();

 

But I can't get the table to move down the page and think it is because I have missed some code somewhere and was hoping somebody could give me a pointer please.

 

At the moment I have

 

<p><?php echo stripslashes($product_info['products_description']); ?></p>

<?php

 

// START Quantity Price Breaks Per Product - My adaption to move the price box down the page

// Need to do a if statement. If there are price breaks, then show the price box here

?>

<table border="0" width="100%" cellspacing="0" cellpadding="2">

<td class="main" align="left" >

This is where i would like to add the price box for in there are price breaks

<?php //Want to add in the price somewhere around here

$pf->loadProduct((int)$_GET['products_id'], (int)$languages_id);

$products_price=$pf->getPriceString();?>

</td></tr>

<tr>

<td width="10"><?php echo tep_draw_separator('pixel_trans.gif', '10', '1'); ?></td>

<?php

// END Quantity Price Breaks Per Product

 

My only thought is there must be some code I have missed that used to call up the price break table at the top of the page.

 

Can anyone help me please??

 

Ali

[Jan Zonjee]

My only thought is there must be some code I have missed that used to call up the price break table at the top of the page.

You need to move the echo'ing (display) of the $products_price to the place you want it to show:

<?php echo $products_price; ?>
