PageBuilderUtmSession snippet

Writes UTM parameters from the query string into $_SESSION['utm']. Used with section visibility rules (settings.utm in the document JSON).

Purpose

Keep campaign tags on first visit so PageBuilder can show or hide sections by UTM in the same request and later in the session.

When to call

The PageBuilder plugin already captures UTM on OnHandleRequest in the web context. Use the snippet if:

• the plugin is disabled on some templates;
• the session starts after the plugin event;
• you want an explicit call in the layout.

Place it before PageBuilder in the site header or base layout chunk.

Parameters

No properties. Call with no arguments.

Call

modx

[[!PageBuilderUtmSession]]

fenom

{'!PageBuilderUtmSession' | snippet}

What is stored

Query	Session
?utm_source=google	$_SESSION['utm']['source'] = 'google'
?utm_campaign=sale	$_SESSION['utm']['campaign'] = 'sale'

Keys are normalized to lowercase. Empty values are ignored.

Parameter registry and defaults live in CMP UTM. Section visibility rules are set in the resource inspector, not in CMP.

Field placeholders

Url and button fields support {{utm:key}} (substituted at render). See CMP → UTM.
