I want to add option for the user to choose the type of the gallery which he is adding. Will it be a slider, masonry gallery or some other type.

I cannot figure it out how I can add custom meta data in the media popup. Here in the screenshot I am showing where I would like to put it.

enter image description here

I would like to add SELECT, with OPTIONs of the Gallery type.

Thank you

Pretty sure it can’t be done.
Best thing to do it just let the user choose images, and choose the gallery type somewhere else.

Hey Design_Mania,

I’ve never tried this myself … but, I have been doing some research into customizing the “Add Media popup” for a current project I’m working on and I think I might have something that can help get you started.

To add meta data to the popup there are a few hooks that can be used: 1. attachment_fields_to_edit 2. attachment_fields_to_save

Here’s a WPtuts+ article on How to Add Custom Fields to Attachments ... though it doesn’t appear to be for galleries I hope it will (if nothing else) get you going in the right direction.

Don’t quote me exactly on any of this, I’m still trying to learn myself … but, I hope it’s enough to start with! ;)
