How to make a unique slug for multiple item region item?

I have a multiple item region with a title field feeding a slug (interesting picture there). Turns out the client wants to use duplicate titles, so we need a way to unique-ify the slug.

I see in the docs that the slug type can take a space-separated list of field ids in the for attribute. Great.

But it doesn't seem to work with the built-in _id.

Example:

<perch:content for="title _id" id="slug" type="slug" />

If the _id is included as a field in the template then it works as expected, but if that field is hidden the _id is no longer included in the slug.

The big question is how can I create a unique slug for a multiple item region item? The next question is can a slug type tag use an _id? (also tried a date, but that didn't seem to work either)

You can use any of the fields that are in the form. _id isn't in the form, so that won't work.

For dates, you need to specify the component, e.g. date_year

Great, thanks Drew. Here's the resulting template tag for anyone finding this through search:

<perch:content for="title date_year date_month date_day" id="slug" type="slug" suppress="true" />
