Hi, I'm not sure about the "two possible conditions". Seems
arbitrary but you could do it with my suggestion by just passing an
array with one value rather than more than one.
Warning, I've only programmed in PHP for about a month now.
What I would do if you, what I do when programming, is ask myself
if I can abstract the code I'm writing. Might I reach out of the
particular instance and see if there is something common in what
I'm doing here. It can take a little longer initially but you can then
use what you've created over and over again. What you wanted to
do sounds like something I've done in Perl so I just re-wrote it in
PHP. I have a module of common routines I nearly always use in
forms and I have the function below in that module (in Perl).
I put it all in a php contstruct so you could test it in your browser.
Pardon all the data. I would not have used the values as the "key"
for the $states array but it did not work unless I put something
there. You can use this for any 2 sets of arrays (states, cities,
colors, sizes, etc....). I have common sets of arrays in my module
as well.
<?php
$states =
