I'm converting an EE 1.x site to the latest 2.x version and have run into a problem where FF Checkbox Groups were used which stored their data as a serialized array whereas both the native and P&T checkbox fieldtypes aren't.

What are my options for upgrading/changing the data?


Have you tried (after making a backup) changing your FF Checkbox fieldtype to the P&T one? It's been awhile since then so I did double check, and found this post confirming that is all that should be needed.

If that isn't working, can you confirm what versions you're going to and from?

Thank you!

  • It's a while since this upgrade first began but I think I might've manually edited the exp_channel_fields table because I was getting errors from those fieldtypes that didn't exist anymore. Upgrade went from 1.6.9 up to 2.5.5 with Matrix 2.5.3. – Tyssen May 28 '13 at 6:19
  • Ok, so at this point, you have an FF Checkbox Groups with data, that is set to... what type of field? – Lisa May 28 '13 at 18:01
  • Well they're no longer FF groups because I manually changed them to first P&T checkbox group and then native checkboxes (when I realised the problem to see if it made any difference). – Tyssen May 28 '13 at 21:49
  • Tyssen, what was the exact output/problem after converting them to P&T checkboxes? – Lisa May 29 '13 at 2:45
  • Nothing gets output in the template because nothing's actually selected, i.e. if you view an entry in the CP, none of the boxes are checked. – Tyssen May 29 '13 at 3:32
