I believe adding :results output should fix this problem, as what you
want is a collection of the text printed to STDOUT.
With that change I get the following...
#+begin_src sh :results replace output
foo=1
if [[ -n "$foo" ]]; then
echo "foo has been defined (and has value $foo)"
else
echo "foo has not been defined"
fi
if [[ -n "$bar" ]]; then
echo "bar has been defined (and has value $bar)"
else
echo "bar has not been defined"
fi
#+end_src
#+RESULTS:
: foo has been defined (and has value 1)
: bar has not been defined
