Session:Set // Statamic 3 Docs

Example

This can be used for many different things. For example, you could set a variable on the form success page if a user has filled out a special survey form.

{{ session:set entered_survey="true" }}

Later you could decide to show a message isntead of the form if the user has already filled it out.

{{ session }}
    {{ if entered_survey }}
        <p>You already filled out the form.</p>
    {{ /if }}
{{ /session }}

Multiple Variables

You can set multiple variables at once and reference interpolated data (references to variables).

{{ session:set likes="hats" :visited="url" }}

Tag Pair

This tag is also available as a pair, which can be used to immediately display set data.

{{ session:set likes="boomboxes" }}
    <p>You like {{ likes }}, huh?</p>
{{ /session:set }}

Setting Array Data

Array data can be set with dot notation.

{{ session:set likes.books="true" likes.hats="true" }}

Forgetting Data

Data can be removed from the session session:forget, and the entire session flushed with session:flush. 🚽
