Hi Fred,

You could create a Relation between the two. Or have a media picker property on the document type that points to the media folder.

Hi Steven,

I'm unsure how either of these could be used to create a matching Media folder. A relation seems to map the 2 items together but not create, and a media picker property would give me the tool to make the folder but would still need to be manually created.

Maybe i'm wrong with Relation, could you give me an example?

Hi Ismail,

That sounds exactly what I need. Out of interest, how did you get the media picker to start at a node, as that was on my todo also

Cheers, Fred

Fred,

I nicked some code from the excellent mvc hybrid project see https://our.umbraco.org/projects/developer-tools/hybrid-framework-for-umbraco-v7/ and the actual code https://github.com/jbreuer/Hybrid-Framework-for-Umbraco-v7-Best-Practises/blob/master/Umbraco.Extensions/Utilities/WebApiHandler.cs so it was using this class and my code looks like

Alright brilliant, Thanks alot!

Hi Ismail,

I've tried implementing the media picker start node, but i'm having the problem of it not working. I have it finding my media node id and running in the correct places which is great.

Is mediaPicker.Config[Constants.MediaPickerStartNodeAlias] something that interacts with the hybrid framework and not in Umbraco by default? If not what is the hardcoded string, or is there a way to implement it that wouldn't be starting again and integrating this framework?

Thanks, Fred

Fred,

Replace Constants.MediaPickerStartNodeAlias with your field alias that has the node id. That bit of code is specific to my situation.

Regards

Ismail

Hi Ismail, the problem was i called it StartNodeId when it's startNodeId...

anyway thank you again it's all working perfectly now, you rock!

Fred

Hi Ismail,

Is there anyway to have it list ancestor nodes so users can still navigate?

it currently just says my folder name but i'd like it to be

root/folder/myfolder so users can still decide where they'd like it uploaded to.

Thanks, Fred

Fred,

Don't think so, I have only used it where I need child folders.

Regards

Ismail

is working on a reply...
