Is there a way to have GetImageList call on every other entry in a MIGX template variable?
From the docs it looks like this will work
[[+_alt]] returns 1 every second row
Thank you, I completely missed that.
No worries, that’s the place to start when you want to do something, just fyi

As a general tip, with many snippets you get access to an
[[+index]]-like placeholder that contains the number of the result in the set. Some start at 0 while others start at 1, but regardless you can use the
mod) output filter to also get the
[[+idx:mod=`2`:eq=`0`:then=`second result`:else=`not a second result`]]
For indexes starting at 0, it’s easy to add 1 first:
[[+idx:add=`1`:mod=`2`:eq=`0`:then=`second result`:else=`not a second result`]]
If there’s already a placeholder like
[[+_alt]] available, using that will save you some processing, but when it’s not, use the modulus.
I did see mod used a few places online, but I never knew what it meant as I can’t seem to find it in the documentation anywhere. Can you clarify its use? Is it simply the equivalent of nth, like is this one of the nth records retrieved?
In this case
mod is short for
modulus. It is listed in the output filter documentation, search for “modulus” on the page.
The modulus is a mathematical concept. If you take an input number (e.g. 10) and provide the modulus (e.g. 4), then the return value is calculated by fitting the number 4 into the input as many times and possible, and returning how much is left. So 4 fits twice in 10, leaving a number of 2.
This is probably the simplest video showing a more visual explanation about the modulus:
With a modulus of 2, that will always either fit exactly, returning 0, or there’s 1 left, which makes it useful for odd/even type things. Eg:
1 = (0 x 2) + 1
2 = (1 x 2) + 0
3 = (1 x 2) + 1
4 = (2 x 2) + 0
