What can I do to train him to always use
the litter box?

You said you empty the box every few days. That is likely the reason
your cat will not use it and pees elsewhere. Would you step barefoot
into a 15" x 20" that had 3 or 4 days worth of urine and feces in it? Of
course not and you shouldn't expect your cat to either.You should use a
clumping litter and scoop the box twice a day, removing all urine and
feces and wash the box and change the litter completely every few weeks
*before* the litter starts to smell. Cats are fastidious creatures and
do NOT like a dirty litterbox. Yours appears to be extra picky and you
need to make sure your cat has an extra clean box. Scooping twice a day
is simple to add to your daily routine and will require no more than one
or two minutes of effort each day.

"Concerning all acts of initiative (and creation), there is one
elementary truth the ignorance of which kills countless ideas and
splendid plans: that the moment one definitely commits oneself, then
providence moves too. A whole stream of events issues from the decision,
raising in one's favor all manner of unforeseen incidents, meetings and
material assistance, which no man could have dreamt would have come his
way."

- W.H. Murray
