Member	rlull - 11/18/2013 10:33:42 AM Macro to get category name from ID? Is there a macro to get the category name by passing in the ID?

You can try the macro below replacing your ID for the CategoryID in the Filters. {%GlobalObjects.Categories.Filter("CategoryID == 1")[0].CategoryName.ToString() + SiteObjects.Categories.Filter("CategoryID == 1")[0].CategoryName.ToString()%}


Member	rlull - 11/18/2013 1:12:17 PM RE:Macro to get category name from ID? Great, thanks. I also found this one: {%SiteObjects.Categories.DisplayNames[8]%}


Certified Developer 13	kentico-jx2tech - 11/18/2013 1:43:18 PM RE:Macro to get category name from ID? You might want to double check that one. The index of the DisplayNames collection might not correspond to the CategoryID.

RE:Macro to get category name from ID?

You're right. I like your way better but I am not quite able to get what I am after. I have the category ID in the url (parameter "DCI") and want to put that into the macro example you provided. I have tried several different ways. For example:

{% SiteObjects.Categories.Filter("\"CategoryID == " + QueryString.GetValue("DCI") + "\"")[0].CategoryName.ToString() %}

Any thoughts? I thought it was just a matter of getting the quotes right but I've tried every combination I could think of.


Certified Developer 13	kentico-jx2tech - 11/18/2013 2:31:23 PM RE:Macro to get category name from ID? I can't get it to work as well. Even a simple concatenation does not work... {%GlobalObjects.Categories.Filter("CategoryID == " + "8")[0].CategoryName.ToString() + SiteObjects.Categories.Filter("CategoryID == " + "8")[0].CategoryName.ToString()%} This might be a bug for the Filter() string parameter.


Member	rlull - 11/18/2013 4:47:20 PM RE:Macro to get category name from ID? I've submitted this to Kentico to see what they have to say. Meanwhile, I ended up writing a custom macro. I can accomplish this now with: {% GetCategoryNameFromID(QueryString.GetValue("DCI")) %}


Member	rlull - 11/18/2013 5:53:09 PM RE:Macro to get category name from ID? Kentico's solution: {% SiteObjects.Categories.Where("CategoryID = " + QueryString.DCI).FirstItem.CategoryName %}


Certified Developer 13	kentico-jx2tech - 11/19/2013 7:30:54 AM RE:Macro to get category name from ID? Thanks for posting that. Still seems odd that Filter() can't handle the string concat.
