Edit Core field in the frontend editor [publish up/down]

Hello, I want to add a date field to the frontend view of an item edit form to allow the users to specify a "Finish Publishing" date.

To do so, I have created a new core field in the flexicontent_fields database because I could not find any other way of creating core fields. My Finish Publishing field is actually just a copy of the "modified" core field with some modifications: The "modified" field appears correctly, so we can assume that the associations to a content type, etc. are correct. The main modification is the reference to the existing publish_down column of the default Joomla content item table.

Now I can see the field in the backend template editor, but I fail to have it show up in the front editor. I have also tried to use field_type = date, but to no avail.

Anyone has an idea what I am missing? Thanks!

It must be added to the template file of the submit/edit form view, and to a helper file and to the core plugin.

But why it must be 'core' ? Please don't do such modifications when not necessary, it will make it difficult to upgrade. Tomorrow you will have an issue/feature that can be fixed with upgrading and it will be difficult to do.

Again why core?

Thanks for your fast reply. The core attributes publish_up and publish_down do exactly what I need and they are already accessible in the backend in the item edit form. There the user can specify on which day an item should be unpublished automatically.
I could not figure out yet how to make these fields available in the content template for the frontend too.
In the content template I can specify which fields to use, but by default there are no fields for publish_up and publish_down, so I thought once these fields exist, I can simply place them in the layout.
(Which indeed seems to work in the backend template editor: the fiels show up and I can place them in the content type form, but they do not show up in the front end, when editing a content item.)

I will look into how to implement this as the fields publish up / publish down already exist in ..._content table (and are useful), maybe today, maybe next days. So, i will not post a hack now ... sorry

I will post a soon as i implement it ...

Thanks a lot, I can wait

I put this in the bug tracker a possible enhancement ... not to forget
