Prestashop 1.7注册Smarty相关产品标签

Question

Introduction

I need to display related products from a product in a different place than prestashop's deffault (however, the theme needs to be capable to show prestashop's default related products block).

I was searching a lot about this and all I can find are modules, tutorials for <1.6 version etc.

I'm using 1.7.2 and those examples don't work to me.

My Expectation :

Register some smarty to use it after and wherever to display product attributes from a related product I want (individually).

For example

{$product.id.accessory.reference} or {$product.id.accessory.image} ,

same with name, description and price.

I suppose it could be

{foreach $accessory ...}
{$accessory.name}
{$accessory.price}
{/foreach}

I'll have only a related product for some products, but i would like to keep a multi-referred product code to ensure it will be useful to everybody.

I'm surprised that prestashop has this functionallity but it's shown on a single place by default (if active) and i didn't found any tag to apply it on another place. Using {debug} i can't see accessory, accessories or related on anywhere.

The point is that we need some steps to reach it and i sincerelly don't know prestashop's core, nor how it deals with smarty or database. I would like to code a custom shop but this is where i'm working now...

i tried this answer but i can't reach the expected: Prestashop: How to get accessories for product

Any help will be great, thanks!

* EDIT *

I tried accessing the public static function through smarty {Product::getAccessoriesLight(intval($cookie->id_lang), $product.id)}

if i var_dump it:

{Product::getAccessoriesLight(intval($cookie->id_lang), $product.id)|@var_dump}

I get:

array(1) { [0]=> array(3) { ["id_product"]=> string(3) "963" ["reference"]=> string(15) "CFPS SAH0-M11-L" ["name"]=> NULL } }

so it's working for getting the product id and the reference, not taking the name (donno why). I'll try another function so and try to discover how to show a single value.

Answer 1

** SOLVED **

prestashop return an array of objects or objects with arrays. Sometimes an array with only a position and this position is an array too. Smarty deals with arrays starting at position 1 depending on the case. It's all a bit confusing logically.

What i did:

create a public static method to access non-static ones (example 1) or create a static method to query something and get results (in which case, using executeS you'll receive the bulk data like the example 2:

{assign var=foo value=Product::getSomethingNew($product.id)}

returns

Object(Product)->values|attrArray->values

in which case, you can do {$foo.value} or {assign var=data value=$foo->attrArray} then {$data.value}

In the second case, you'll get:

Array[1]->array[data] so you can simply: {$foo[1].value}

And obviously, it works wherever you need as you create your own methods to access data.

I didn't found the logic or the reason for some arrays to being null at 0 index but having values from index 1 and others start normally at index 0 but... I was getting different attribute values on a product object for the same ID so i don't mind on investigate too much on prestashop. It seems a school project that went too far...

Hope it helps someone.
