i. If/Else
The If-Else-Unless structure from the Liquid library allows you to branch HTML statements just like you would with a traditional programming language. It’s easy to implement and takes just a few steps.
The example below shows how you can create an If-Else structure to show different links to logged in and logged out users in the portal.
{% if portal.user %}
>
> <a href="{{ portal.profile\_url }}">Edit profile</a></span>
>
> <a href="{{ portal.logout\_url }}">Signout</a>
>
{% else %}
>
> <a href="{{ portal.login\_url }}">Login</a>
>
> <a href="{{ portal.signup\_url }}">Signup</a></span>
>
{% endif %}
ii. Cases:
Liquid Cases are similar to switch cases used in popular programming languages. It checks a single expression with multiple values and branches with different statements correspondingly.
{% case forum.type\_name %}
>
> {% when ‘announcement’ %}
>
> > <!\-\- Style for announcements forum -->
> {% when ‘ideas’ %}
>
> > <!\-\- Style for Idea forums -->
> {% when ‘questions’ %}
>
> > <!\-\- Style for questions forum -->
> {% when ‘problems’ %}
>
> > <!\-\- Style for problems forum -->
> {% else %}
>
> > <!\-\- Default forum style -->
{% endcase %}
Switch cases come in handy especially when you want to provide a different style based on the solution category or forum topic type.
