I reliazed that problem, but it seems I can not fix the problem, here is the modified script
awk '{ for (i=0; i<=NF; i++)
if($i~/user/)
{a=$i}
else
{a="no"}
{ continue}
{print a}
}' /tmp/test
and the output change to
no
user_d
user_a
no
no
which is not correct at all.

Perhaps as the first line ater your else, do a Code:
a=""
to blank out the last 'a' value?
