How can I display a specific product in liquid using array?

[yungmuehle]

I have the following code and i am trying to display a specific product by the value in the Array "products" . Is this possible ? 
My goal is to have the opportunity to call a random product by its ID in a specific collection. 

Thanks for your help ! 

{% assign collection = collections['TEST] %}

{% for product in collection.products %}

<div class="informations">

<a class="ProductName">{{ product.title[2] }}</a>

</div>

{% endfor %}

Hi @yungmuehle, see if you can make the below Liquid code work,

{% assign collection = collections['TEST'] %}
{% assign specific_product_id = 1234567890 %} <!-- Replace with your specific product ID -->
{% for product in collection.products %}
  {% if product.id == specific_product_id %}
    <div class="informations">
      <a class="ProductName">{{ product.title }}</a>
    </div>
    {% break %}
  {% endif %}
{% endfor %}

Hope it's a good start for you.

Awesome thank you ! But is there a logic behind numbers of the Product ID ? Because i am looking for a range to select them randomly

Okay let's improve the code. Try this,

{% assign collection = collections['TEST'] %}
{% assign product_ids = '1234567890, 9876543210' | split: ', ' %} <!-- Replace with your product IDs -->
{% assign random_index = 'now' | date: '%s' | modulo: product_ids.size %}
{% assign random_product_id = product_ids[random_index] %}

{% for product in collection.products %}
  {% if product.id == random_product_id %}
    <div class="informations">
      <a class="ProductName">{{ product.title }}</a>
    </div>
    {% break %}
  {% endif %}
{% endfor %}

• Replace '1234567890, 9876543210' with the IDs of the products you want to include in the array. These should be the actual numeric IDs of the products.
• The random_index line generates a random number based on the current timestamp and uses it to pick an ID from the product_ids array.
• The for loop iterates through the products in the collection and displays the product that matches the randomly chosen ID.

i think .size is wrong because it returns the number of characters in a string or the number of items in an array. Not the value

I am making progress and now it looks like the value for the "random_id" item isnt recognized in the if-loop. I think its because of the format because when i compare it to the actual product ID it works fine. 

{% assign collection = collections['TEST'] %}

{% assign product_ids = '8841905635651, 8841909403971' | split: ', ' %}

{% assign random_id = product_ids[1] %}

{{ random_id }}

{% for product in collection.products %}

{% if product.id == random_id %}

<div class="informations">

<a class="ProductName">{{ product.title }}</a>

</div>

{% break %}

{% endif %}

{% endfor %}
