How should I get Keyword Key from DWT

This is similar to this XSLT question, but ultimately for DWT.

We can get a keyword's key via a C# TBB.

ItemFields fields = new ItemFields(component.Metadata, component.Schema);
KeywordField keywordField = fields["state"] as KeywordField;

String stateValue = package.EvaluateExpression("Component.Metadata.state");

package.PushItem("statekey", package.CreateStringItem(ContentType.Text, keywordField.Value.Key));

In DWT, I sometimes want the key of a selected keyword in a component.

Is adding and getting these from the package the correct approach?

@@Component.Metadata.State@@ gets me the value. Referencing the key directly from DWT would be great, but I haven't seen anything to suggest DWT exposes it.

Solution

  • As another alternative to John's answer. How about taking a similar approach to Will's "Get Component Template Uris" and write a TBB that iterates over a category's keywords and writes them out into the package with the desired output value? You'd then be able to use these values directly from DWT with a "double-evaluation" like:

    @@Keyword${Component.Metadata.state}Value@@
