function TermReferenceField::GetTid in Realistic Dummy Content 8

Returns the term id for a term which is either existing or created on the fly.

Let's say an entity (node) contains a term reference to the taxonomy vocabulary "location", and in the realistic dummy content file structure, "Australia" is used for the location. If "Australia" exists as a "location", then this function will return its tid. If not, the term will be created, and then the tid will be returned.

Parameters

$name: The string for the taxonomy term.

Return value

The associated pre-existing or just-created tid.

Throws

\Exception
