My Add-On for MAP (minimum advertised price).

[DrByte]

The Plugin still displays etc but the quantity discounts displayed below the pricing show the lower price that is not supposed to be shown.

If you're using MAP pricing then you're probably requiring customers to add-to-cart to see the price, so therefore you don't want the discounts box to show at all;
therefore, you can cause it to no longer display by editing:
/includes/templates/YOUR_TEMPLATE_DIRECTORY/templates/tpl_product_info_display.php
You could remove the entire following section of code, or you could just make the change in red:

<!--bof Quantity Discounts table -->
<?php
  if (false && $products_discount_type != 0) { ?>
<?php
/**
 * display the products quantity discount
 */
 require($template->get_template_dir('/tpl_modules_products_quantity_discounts.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_products_quantity_discounts.php'); ?>
<?php
  }
?>
<!--eof Quantity Discounts table -->

Suggestion, This is the kind of item that should automatically part of Zen as thanks to Amazon, Map pricing now pretty much enforced across the board.

Should I be overwriting the newer code with this older code. For example, the update_product.php file has more code in the newer zen version than does the MAP file of the same name. Is overwriting safe to do?

Absolutely not! You'll need to perform a file-compare (using a program like WinMerge or Beyond Compare) to merge the MAP changes into that updated version.

MAP VERSION: if ($_POST['image_delete'] == 1) {
Zen version: if (isset($_POST['image_delete']) && $_POST['image_delete'] == '1') {

a number of these types of variations, in this case I remove the zen version and replace it with the MAP version of the code?

No, you do just the opposite - assume ZC code is new and improved. And you only merge the parts that are directly related to the plugin you're installing, meaning the line that mentions MAP or the entire block of code that is about MAP (it's usually commented). In the case of update_product.php file, it's literally just 2 lines of code that need to be added. Here's the entire file for you, you can use it to understand how it's done:

This is Module support zc 1.5.8?

[jimmie]

how do i make this work,

if ($is_map_enabled == 0 && $products_discount_type != 0) { ?>

because not all products are map enabled, still want to show on non mapped products

[clam_man]

Has anyone come up with a solution for an add-to-cart to see price for 1.5.8a? I looked through the stock settings and didn't see anything. I'm migrating/updating a site and its database to this newer version from 1.5.6b and I still have the data from the old database for which products have MAP turned on. I understand that just hiding the price on the front-end via JS will not keep bots from crawling the site and seeing/saving the price info so I know I'll have to make this change in the PHP. If there is no solution at the moment then can someone answer for me if the product_info template file is the one I would need to make modifications to in order to get the desired behavior? I'm using a non-stock template so I don't think my solution will be of value here but I can post what I learned and if I have some extra time I can go through the stock template file and post a solution for that. My only worry is data not posting correctly to the shopping cart but I'm sure I can figure that out if I come across it. All I am trying to do is have the template populate an 'add-to-cart for price' button where it normally populates with the price if the products table has a 1 in map_enabled for that individual products that it is querying. Thanks in advance!

[clam_man]

Well I've come up with a working solution to this issue on ZC 1.5.8a. I modified the products table in the database, the tpl_product_info_display.php, the collect_info.php, and the update_product.php files in order to get 'Add to Cart to View Price' functionality working. I have never published a plugin before for Zen Cart, so it may take me a bit to figure out how that all works but is anyone interested in this before I spend the time adapting the solution for the vanilla files?
