Set and Get

The Set and Get tags are useful for remembering a value to use later, or in multiple places.

This is commonly called a "variable", which has a unique name and holds a reference to a value. For global variables and all variable types except local, variable values are stored in the memory during a single page load. They are only available after they've been assigned, within the template itself, and for other templates loaded after or below it.


Use the Set tag to save a value in the memory by a given name.

In the example below, the current post ID is stored in a variable called current_id.

<Set name=current_id>
<Field id />

As a shortcut, the name can be given directly as the first attribute.

<Set current_id>...</Set>

Dynamic name

The attribute name can be used to create a dynamic variable name.

<Set name="{Get X}_output">...</Set>


Use the Get tag with a variable name to get the value.

<Get name=current_id />

Pass variable to tag attribute

The Get tag can be used to pass a variable to a tag attribute.

<Field name="{Get X}">

Inside the attribute, angle brackets <> need to be changed to {}.

Variable types

In addition to regular variables, there are other variable types with special behavior.

These can be accessed by using an attribute name of the variable type, instead of the name attribute.

For example, to get the site URL:

<Get url=site />

Most of the variable types have a tag as a shortcut. The above is equivalent to:

<Url site />

For details, see the page for each variable type.

Template variable

The template variable type is useful for storing templates, then rendering them later, or in multiple places.

This is in contrast to regular variables, which are rendered upon setting them.

For example, to create a reusable template:

<Set template=title_and_content>
<h1><Field title /></h1>
<Field content />

It can be used anywhere, such as inside a loop.

<Loop type=page count=1>
<Get template=title_and_content />

Local variable

A local variable only exists within a template post or file and any "child" templates loaded inside of it. These variables do not exist for templates that are loaded on the page after or below the template. Every template gets a fresh set of memory for local variables when it's loaded which is available for itself and its children.

Use the local attribute to set and get local variables.

<Set local=variable_name>..</Set>

<Get local=variable_name/>

Local variables are useful for templates that you plan to share with other people, to make sure the template doesn't change variables used outside of it.

JS variable

This is a way to pass values to the Script section of a template post.

<Set js=variable_name>..</Set>

A valid variable name must include only alphanumeric (letters and numbers) and underscore _. It cannot include a dash -.

Use the type attribute to define the value type: number, array (or list), object (or map), and string. string wraps the value in "quotes" while all other types work the same as the default by passing an unquoted value.

Sass variable

This is a way to pass values to the Style section of a template post.

<Set sass=variable_name>..</Set>

A valid variable name must include only alphanumeric (letters and numbers), underscore _, and dash -.

By default, the value of Sass variables are saved without quotes so that variables containing numbers or hex colors work as expected. When working with strings or URLs, these values need to be quoted. Use the type attribute to define the value type: number, color, list, map, and stringstring wraps the value in quotes "" while all other types work the same as the default by passing an unquoted value.

For example, an image URL variable could be saved using either of the approaches below.

<Set sass=background_image>"<Field image_url />"</Set>
<Set sass=background_image type=string><Field image_url /></Set>

This variable can then be referenced in the Style tab.

background-image: url($background_image);
