How to display custom variables of knowledge article in Knowledge Hompage?

snowE · ‎01-17-2022

Hi All,

I've been stuck on this task, where I have to display knowledge articles on Knowledge homepage which contain custom variables. The kb_view UI page has the following HTML code which displays data on Knowledge Homepage. The same implementation has been done for Widget controller on Service Portal which works as expected. The custom field Introduction is not displaying in the Knowledge Homepage.

kb_view UI page HTML code:

-----------------------------------------------------------------------------------------------------------------------------------

This worked for me for kb_knowledge custom fields on the article. But what should i do for kb_template_incident_kcs_article fields on the article?

You have to edit UI macro called "kb_view_common_content" to display new data in KB.
