Has anyone found a way to dynamically assign variables in Liquid?

We're building a translation architecture using Braze catalogs to serve localised email content across 30 markets. We want a universal content block where marketers simply define which keys they need for each email (subject line, preheader, header text, CTA etc.) and the block fetches and assigns the translations dynamically based on the user's locale.

Ideally we'd do something like this:

liquid

{% assign pull_keys = "welcome_subject_line,welcome_preheader,welcome_header_text,welcome_cta_1" | split: "," %}{% for key in pull_keys %}  {% catalog_items email_translations {{key}} %}  {% assign {{key}} = items[0][locale] | default: items[0]['en-AU'] %}{% endfor %}

So in the email body we could just reference:

liquid

{{ welcome_subject_line }}{{ welcome_preheader }}{{ welcome_header_text }}{{ welcome_cta_1 }}

But we're hitting this error:

Liquid syntax error: Syntax Error in 'assign' - Valid syntax: assign [var] = [source]

Has anyone found a workaround for this? Would love to know how other companies are handling email content translation at scale in Braze. Are you using catalogs, Connected Content or something else entirely? Any approaches or workarounds appreciated!

Hello @Nirnay What we are doing is using canvas id as key and then subject line, preheader are other columns in the catalog.

Marketer will just populate the catalog with canvas id and related field. Then we just show/hide the fields based if they were populated or not.

Or you could do something like this.

{%- assign fields_to_use = "welcome_subject_line,welcome_preheader,welcome_header_text,welcome_cta_1" | split: "," -%}


{%- catalog_items dynamic_content_block {{canvas.${api_id}}} -%}

{%- assign canvas_data = items[0] -%}

{%- if canvas_data -%}

  {%- for field in fields_to_use -%}

    {%- if field == "welcome_subject_line" -%}

      {%- assign welcome_subject_line = canvas_data.welcome_subject_line -%}

    {%- elsif field == "welcome_preheader" -%}

      {%- assign welcome_preheader = canvas_data.welcome_preheader -%}

    {%- elsif field == "welcome_header_text" -%}

      {%- assign welcome_header_text = canvas_data.welcome_header_text -%}

    {%- elsif field == "welcome_cta_1" -%}

      {%- assign welcome_cta_1 = canvas_data.welcome_cta_1 -%}

    {%- endif -%}

  {%- endfor -%}

{%- endif -%}
