An alternative to offest = “-1” in Expression Engine

Question

Does anyne know how expression engine deals with a negative offset in a list of channel entries in EE?

as in offset="-1"

Answer 1

If you use offset="-1" in {exp:channel:entries}, you'll get a major MySQL error (assuming you're logged in as a super admin or are capable of seeing errors).

It's unclear what your goal is from your question. If you expect a negative offset to reverse the order (like PHP string functions), you can use use the opposite sort value. The default is desc, so sort="asc" would be the reverse. Use a positive offset="X" to skip X entries.

If you're expecting an offset like in PHP array_slice where you're still going "forward" but a negative offset starts you X entries from the end, I don't believe there's a direct comparison.

Answer 2

The goal was to work with the preceding chanel entry on the same page as the current channel entry.

I managed to do it instead by pulling out the relevant entry_ids and processing them in php and then put them back in with a fixed_order attribute
