True! Bit me in the behind before where I was staring at a blank page in
the browser not knowing why.
You expect users to weigh platinum by the pound;
someone will try to weigh chicken necks by the ounce.
Or in general, uses metric. "23" can be anything and if not made clear
it might as well drill your multimillion $ space probe straight into
Mars. Honestly, Americans with their "English" system don't deserve
better. ;)
You expect users to pay in Dollars, Punds, Yen, Franc, Lire and Marks;
someone will try to pay in Real.
See above, depends on which Franc you are talking about. And even worse,
French Franc, Italian Lira, and German Marks don't exist anymore.
You expect 5-digit numerical Zip;
UK users have 6-char alpha/numeric mixed.
I dove into this some time ago and there are about a dozen standardized
means of writing an address. I think I have that code somewhere to
handle this. That covers at least the majority of cases, but for sure
not all.
You execute a cart in English, Japanese and Spanish;
a user is visually impaired and speaks native Dutch.
Or is German and has an attidue like Simon Cowell.
Incomplete function logic tree I have seen many times:
if
dollars do this
elseif
yen do this
elseif
marks do this
else
pounds do this
end if
This one precuationary step alone will CYA so many times you may appear
teflon.
Or use switch, case, and default, which supposedly is the better
approach since the Logo days.
