Get next and previous elements out of an array in liquid

Question

Short version:

I want to add 1 to a number in a liquid template and use the result as an array index.

{% capture plus_one %}{{ 0 | plus: 1 }}{% endcaptur         


        

Answer 1

You can access the next / previous post via page.next or page.previous as described in the jekyll wiki.

When you want it to be in the same category, you have to assign it to a temp variable iterate that step until you find a matching post (a post in the same category).

You can not use your plus_one variable because of the way liquid works - it's just a string. Using math in liquid is quite complicated, I almost got a headache when I implemented my weighted tag cloud in liquid.
