Helpers
Default Fallback Value
The Default Fallback Value helper is used to return a default fallback value if an attribute is empty or null. This mechanism works for Profile attributes and Journey events.
Syntax
Hello {%=profile.personalEmail.name.firstName ?: "there" %}!
In this example, the value there is displayed if the firstName attribute of this profile is empty or null.
Conditions
The if helper is used to define a conditional block.
If the expression evaluation returns true, the block is rendered otherwise it is skipped.
Syntax
{%#if contains(profile.personalEmail.address, ".edu")%}
<a href="https://www.adobe.com/academia">Check out this link</a>
Following the if helper, you can enter an else statement to specify a block of code to be executed, if the same condition is false.
The elseif statement will specify a new condition to test if the first statement returns false.
Format
{
{
{%#if condition1%} element_1
{%else if condition2%} element_2
{%else%} default_element
{%/if%}
}
}
Examples
-
Render different store links based on conditional expressions
code language-sql {%#if profile.homeAddress.countryCode = "FR"%} <a href="https://www.somedomain.com/fr">Consultez notre catalogue</a> {%else%} <a href="https://www.somedomain.com/en">Checkout our catalogue</a> {%/if%} -
Determine email address extension
code language-sql {%#if contains(profile.personalEmail.address, ".edu")%} <a href="https://www.adobe.com/academia">Checkout our page for Academia personals</a> {%else if contains(profile.personalEmail.address, ".org")%} <a href="https://www.adobe.com/orgs">Checkout our page for Non Profits</a> {%else%} <a href="https://www.adobe.com/users">Checkout our page</a> {%/if%} -
Add a conditional link
The following operation will add a link to the ‘www.adobe.com/academia’ website for profiles with ‘.edu’ email addresses only, to the ‘www.adobe.com/org’ website for profiles with ‘.org’ email addresses, and the default URL ‘www.adobe.com/users’ for all other profiles:
code language-sql {%#if contains(profile.personalEmail.address, ".edu")%} <a href="https://www.adobe.com/academia">Checkout our page for Academia personals</a> {%else if contains(profile.personalEmail.address, ".org")%} <a href="https://www.adobe.com/orgs">Checkout our page for Non Profits</a> {%else%} <a href="https://www.adobe.com/users">Checkout our page</a> {%/if%} -
Conditional content based on audience membership
code language-sql {%#if profile.segmentMembership.get("ups").get("5fd513d7-d6cf-4ea2-856a-585150041a8b").status = "existing"%} Hi! Esteemed gold member. <a href="https://www.somedomain.com/gold">Checkout your exclusive perks </a> {%else%} if 'profile.segmentMembership.get("ups").get("5fd513d7-d6cf-4ea2-856a-585150041a8c").status = "existing"'%} Hi! Esteemed silver member. <a href="https://www.somedomain.com/silver">Checkout your exclusive perks </a> {%/if%}
Unless
The unless helper is used to define a conditional block. By opposition to the The if helper, if the expression evaluation returns false, the block is rendered.
Syntax
{%#unless unlessCondition%} element_1 {%else%} default_element {%/unless%}
Example
Render some content based on email address extension:
{%#unless endsWith(profile.personalEmail.address, ".edu")%}
Some Normal Content
{%else%}
Some edu specific content Content
{%/unless%}
Each
The each helper is used to iterate over an array.
The syntax of the helper is {{#each ArrayName}} YourContent {{/each}}
We can refer to the individual array items by using the keyword this inside the block. The index of the array’s element can be rendered by using {{@index}}.
Syntax
{{#each profile.productsInCart}}
<li>{{this.name}}</li>
</br>
{{/each}}
Example
{{#each profile.homeAddress.city}}
{{@index}} : {{this}}<br>
{{/each}}
Example
Render a list of products that this user has in their cart:
{{#each profile.products as |product|}}
<li>{{product.productName}} {{product.productRating}}</li>
</br>
{{/each}}
With
The with helper is used to change the evaluation token of template-part.
Syntax
{{#with profile.person.name}}
{{this.firstName}} {{this.lastName}}
{{/with}}
The with helper is useful to define a shortcut variable too.
Example
Use with for aliasing long variable names to shorter ones:
{{#with profile.person.name as |name|}}
Hi {{name.firstName}} {{name.lastName}}!
Checkout our trending products for today!
{{/with}}
Let
The let function allows an expression to be stored as a variable to be used later in a query.
Syntax
{% let variable = expression %} {{variable}}
Example
The following example lets all sums of product totals with the transaction in USD where the sum is greater than $100 and less than $1000.
{% let variable = expression %} {{variable}}
