I have a content type App with a term reference field called App category.
I'm creating a view page with path app/%. I don't want to use App ID or anything numeric in URL in place of %, so I'll be using app/cooking-app where cooking-app is URL Alias of App Category.
How can I display all the nodes whose value in App Category field is cooking-app? I can easily do this using PHP code but PHP code in contextual filters is not working.
