How to return an array of product ID's wrapped in apostrophes with liquid variables?

Technical Q&A

Hi!

I’m in the midst of setting up retargeting tags for the purchase conversions. Part of a tag I need to set up requires me to list strings of all product ID’s of products in the cart.

As an example, say I have 3 products with the following ID’s:

123

456

789

I’d need to return these in an array of strings like so: ‘123’,‘456’,‘789’ .

I stumbled upon a stackoverflow thread that helped me get part of this done:

Best way to do that is to use arrays. Because they have map and unique.> > This code will return array of unique product IDs> > > *{% assign uniqueProductIdsArray= cart.items | map: 'product_id'| uniq %}*> > > This code will return concatenated string of unique product IDs> > > *{% assign uniqueProductIdsString= cart.items | map: 'product_id'| uniq | join: ', ' %}*>

This setup allows me to get an array of product id’s (so just 123,456,789) and I can of course simply add apostrophes to the beginning and end of this list of product id’s, but unfortunately this an incorrect syntax in this instance. How could I return these ID’s joined by commas and wrapped in apostrophes (each ID separately)?

Since we don’t really mind if the created array has weird values in it (we only care about the output!) you can cheat and just join the array using “,” and then add " on both ends.

For example:

{% assign uniqueProductIdsString = cart.items | map: 'product_id'| uniq | join: '","' %}
 "{{ uniqueProductIdsString }}"
