Add an arbitrary id to each repeater instance

I have a repeater field called slides. In it I have slides, that each have a title and an image. These slides get added to a page as a slideshow. Not terribly complicated.

I need to add an id or random string to each slide, so I can jump to the slide based on a url:
/slideshow/a1b2c3

Will jump to the 5th slide that has the id of a1b2c3.

I have the code to do the slide selection. Now I just need help adding an id to each custom field.

I can’t use the slide number, as it’s stored in the database, because the order might change. I can’t use the title or image id, because they might change.

Any suggestions on how to add a unique id or string to each repeater field? Thanks!

Thanks. That’s actually the first thing I tried. The problem with those solutions is the “id” changes if you change the order. I want to link to a slide (my sub_field), even if I change the order.

I looked at the template for making an addon. It seems like making a unique id custom field would be very easy.

The unique id addon is done. Is there somewhere I can put it online for other people who might need it?

Hi @gelform

Nice work. Github is your best place for 3rd party fields.

Thanks

+1 for this.
Id be very interested in looking into how you’ve built this addon.

Can you perhaps provide a link to github?

EDIT: Never mind, I then realised I had to do that myself in the php 🙂 All good.

Hi @KLicheR,

I’m sorry to be such a noobie, I’ve added the plugin, activated it, and upon pressing “Update” a unique id gets generated for each repeater row. However, how do I now create a hyperlink to that specific row? The unique id does not seem to have been added anywhere to the DOM?

Thanks,
Mar
