So I just spent 3 days trying to write a custom WordPress query with WP_Query and limit the result set with tax_query. I wrote my own code, copied and pasted code from the docs and watched a couple of tutorials, no matter what I did my results just weren't right. Turns out I was calling my code too early so my tax_query was being ignored.

Time wasted or lesson learnt?
.... I'll take lesson learnt. Oh well.
