No. Since the book is designed for newbies, as far as I can see anyway, I
think that there should be a section somewhere explaining that parameters in
the CGI world work different from parameters in the command line script
world. You should explain how the argument array is not used in
CGI/mod_perl, but rather paramters are passed as key/value pairs which are
read from the request. Explain the basics of it, and maybe give an example
HTML snippet like:
<INPUT TYPE="TEXT" NAME="givenName">
<INPUT TYPE="TEXT" NAME="lastName">
<INPUT TYPE="HIDDEN" NAME="emailAddress" VALUE="[EMAIL PROTECTED]">
And explain that if the user typed in "Issac" in the first box and
"Goldstand" in the second box, his perl script would get these paramters in
a key/pair list (which can be placed into a nice little hash) and then
accessed...
Give a little example:
print "Hello $form{givenName} $form{lastName}. Your email address is
$form{emailAddress}.\n";
That's what I was referring to. And I don't _think_ it's in the book. And
if you'll look at the original question, it apparatly IS a newbie issue.
