(SOLVED temporarily) show "manufacture product number" or "MPN" when select a combination

[hogo20]

hello everyone 

I use Combination in my PrestaShop store.

is it possible to show "manufacture product number" or "MPN" code, when select a combination? 

in PrestaShop 8.2 when assign MPN code (or UPC), it does not show anything about that in front office. 

( In the attached picture, my wish is better determined.) 

Thank you for your help

Hello

Add the code

  {foreach from=$product.specific_references item=reference key=key}

    <dt class="name">{$key}</dt>

    <dd class="value">{$reference}</dd>

  {/foreach}

to your theme file at

themes/our_theme/templates/catalog/_partials/product-variants.tpl

hello dear, thank you for your help. 

I added your recommendations to end of product variants file. 

but not show any new thing in front office. 

images attached 

[hogo20]

also, already assign mpn, upc, ean13 numbers in product combination

Try clearing the cache

[Ewonta]

That's how it should be displayed

[hogo20]

Hey, did you just do this? 🤔

I clear the cache from:

1- admin =advanced parameter >performance 

2- host= var >cache

But I didn't see any change. Strange! 

I have PrestaShop 8.2 with PHP 8.1.

Should I install and test a new on LocalHost or is there a point? 

Thank you bro 

[Ewonta]

I have the same version, are you sure that you did it in that folder of the theme, you need to do it in the active folder of the theme.

[hogo20]

Your recommendations code is on:

public_html/themes/classic/templates/catalog/_partials/product-variants.tpl

(In this path, I added some codes to display the inventory of each combination of goods and works fine. So the folder is correct and runs from it.) 

It's also strange to me why it doesn't work.

Take a close look at the message, I fixed it right away because I didn't know what your theme was.

our_theme

[hogo20]

i use default classic theme.

Send the link to the product

[Ewonta]

You obviously have some kind of cache enabled on the server, with hard page caching. 

The product-quantity block is displayed, you have sent a screenshot that you have inserted the code into the required file.

 

<div class="product-quantities" style="font-weight: bolder;">
        <label class="label">In stock</label>
        <span data-stock="1" data-allow-oosp="1">1 Items</span>
      </div>

1) either the code was inserted into the wrong file.

2) Either the server has hard-coded the file

[hogo20]

to show quantities, I copy some code fron other file and insert to product-variants.tpl file and works fine. 

about server side hard cache, I don't know. must be contact  with host manager? 

Edited January 23 by hogo20 (see edit history)

[Ewonta]

Try asking the hosting manager.

[hogo20]

I gave a ticket to the server administrator and they offered a way to remove the server cache. By doing that, it didn't work. I decided to install and test a fresh version on LocalHost. 

Thank you for your guidance. 🙏

hello

today, install prestashop 8.2.0 on localhost and live host > in both situation, that recommendation does not work.

[hogo20]

hello, friends

In Prestashop 8.2.0, open file:   /controllers/front/ProductController.php

and remove line 1207 (with this code):

$product['cart_quantity'] = $this->context->cart->getProductQuantity($product['id_product'], $product['id_product_attribute'])['quantity'];

then add this code to: /themes/[your theme]/templates/catalog/_partials/product-variants.tpl

    {block name='product_specific_reference'}
        <p class="product-specific-reference"  style="font-weight: bolder;">
            {foreach from=$product.specific_references item=reference key=key}
            <span class="name">{$key}: </span><span class="value" style="color:#005fff;">{$reference}</span><br/>
            {/foreach}
        </p>
    {/block}

Changing the behavior of the system in this way is not the best option, deleting

 /controllers/front/ProductController.php

has nothing to do with

{block name='product_specific_reference'}
        <p class="product-specific-reference"  style="font-weight: bolder;">
            {foreach from=$product.specific_references item=reference key=key}
            <span class="name">{$key}: </span><span class="value" style="color:#005fff;">{$reference}</span><br/>
            {/foreach}
        </p>
    {/block}

It is better not to delete directly, you always need to override classes and controllers.

[hogo20]

yes, you're right.

how can override productController.php from that path?

thank you for your attention

[Ewonta]

The Override is described in the PrestaShop documentation https://devdocs.prestashop-project.org/8/modules/concepts/overrides/

[hogo20]

hello, this method make new problem. 

When pre-order is active, The minimum order number is not automatically entered in the relevant box. However, this method can be used to solve it in the next version, hopefully.

This feature has nothing to do with your question, it's a mistake.
 

$product['cart_quantity'] = $this->context->cart->getProductQuantity($product['id_product'], $product['id_product_attribute'])['quantity'];

Yes, it's possible to display the MPN code when selecting a combination in PrestaShop, but it may require some custom development. You'll likely need to modify the product.tpl file in your theme and use PrestaShop's hooks to fetch and display the MPN dynamically in the front office.
