Control Flow with Conditional and Logical Operators

Like most other programming languages, Scriptlets support if and else statements to only output content when certain conditions are met.

if elsif

{% assign name = "{{ Your Full Name }}" %}
{% if name == "Ronald" %}
  Hello {? name ?}
{% elsif name == "Sofia" %}
  Hola {? name ?}
{% else %}
  Hi {? name ?}
{% endif %}

if else (OR)

{% assign name = "{{country name}}" %}
{% if name == "Holland" or name == "Netherlands" %}
 The flag of {{country name}} is 🇳🇱
{% endif %}

if else (AND)

{% assign name = "{{Country Name}}" %}
{% assign lowername = name | downcase %}
{% assign uppername = name | upcase %}
{% if lowername == "india" and uppername == "INDIA" %}
  We're open in {{ Country Name }}
{% else %}
 Sorry, we are not in {{ Country Name }} yet!
{% endif %}

if else (Number)

{% assign number = "{{Student Age}}" %}
{% if number > 18 or number == 18 %}
 Appliant is an adult!
{% else %}
 Applicant is {? number ?} years old!
{% endif %}

switch case

Use the switch statement to compare a variable with different values

{% assign name = "Alejandro" %}
{% case name %}
 {% when "Alejandro" %}
  Hola {? name ?}!
 {% when "Oliver", "Arthur", "Freddie" %}
  Hello {? name ?}!
 {% else %}
  Do I know you {? name ?}?
{% endcase %}

unless

This is the exact opposite of the if statement. It will only render the block if the condition is false.

{% unless {{ Country Name }} == "USA" %}
 Applications from {? {{Country Name}} | capitalize ?} are not accepted.
{% endunless %}

capture

Captures the string inside of the opening and closing tags and assigns it to a variable. Variables created through capture are strings.

{% capture var_name %}
how are you
{% endcapture %}
{? var_name | strip | capitalize | append: "?" ?}

// Output: How are you?

Capture a complex string contain a variable name

{% assign name = "Angus" %}
{% capture greeting %}how are you {? name ?}
{% endcapture %}
{? greeting | strip | capitalize | append: "?" ?}

// Output: How are you Angus?
