pdoField

This snippet combines getResourceField and UltimateParent: it outputs any field of a specified resource or its parent, including TV parameters.

Unlike those, it works with documents in any context and allows extra select parameters (e.g. to exclude fields of hidden resources). With &class you can get a field of any MODX object. Can be used as output filter.

Parameters

Accepts general pdoTools select and output parameters plus:

Parameter	Default	Description
&id	Current document	Resource ID.
&field	pagetitle	Resource field.
&top		Selects parent of &id at level &top.
&topLevel		Selects parent of &id at &topLevel from context root.
&default		Resource field to return if &field is empty. Faster than :default= filter.
&output		String to return if both &default and &field are empty.
&toPlaceholder		If set, snippet stores data in placeholder instead of outputting.

If &top or &topLevel is used and &context is not set, an extra DB query will determine the context.

Snippet does not support chunks; it returns only one field value.

Examples

As output filter:

[[*id:pdofield=`longtitle`]]

Parameters as JSON. Second parent and its longtitle:

[[*id:pdofield=`{"top":2,"field":"longtitle"}`]]

Regular call is faster and clearer:

[[pdoField?
  &id=`[[*id]]`
  &field=`longtitle`
  &top=`2`
]]
