Liquid Filters Documentation

[minerkt]

I stumbled across this reference at the bottom of the liquid variables reference page for handling filters as a liquid variable.

{{ _filters['view_name.field_name'] | split:"," | sql_quote | join:"," }}

That end portion with the “split” and “join” functions, I decided to try something with a “remove” function that ended up working.

For example, if the “view_name.field_name” in the filter was “Mississippi” and I used the following liquid filter, we would get the following returned.

{{ _filters['view_name.field_name'] | remove:"i"}}

returns: "Msssspp"

Another use case would be stripping the “%” from a “contains” filter to just get the value elsewhere.

Is there any documentation that discusses the different operators/functions like “split”, “join”, “remove” and how to best use them?

Can we use lower or upper function around liquid variables? I am getting error..
{%- if lower(user_email_domain) == 'yahoo.com'  -%}

how to overcome this issue? please help.

Hi @rkancha2024 , you can't use sql type functions such as lower() within liquid.

However, you can use what are called liquid filters to achieve a similar result.
In this case, we would need to make user_email_domain._value into lowercase.

The syntax could look like {% if user_email_domain._value  | lowercase == 'yahoo.com'  %}
However, from my testing, it seems like adding filter statements into a conditional doesn't work as I would like, so we should take this approach instead.

1. Assign the lowercase value to a liquid variable: {% assign user_email_domain = user_email_domain._value | downcase %}
2. Evaluate the liquid variable to your string: {% if user_email_domain == 'yahoo.com'  %}
   

Please note though, that gettings field values such as _value can only be used in action/html/link parameters as according to the docs.

If you want to evaluate in sql you would just use standard CASE WHEN lower(user_email_domain) = 'yahoo.com' THEN xxx ELSE END kind of syntax.
