Re: tutorials
It is a very good book, but I am not sure it is what the original poster was looking for, I don't think it is geared towards the cgi spectrum of Perl. It is great for doing specific tasks, many of which can be implemented in multiple arenas, but as a CGI book it really isn't. Along with the CGI Programming with Perl there is also this book from ORA: http://www.oreilly.com/catalog/perlwsmng/ Sorry I can't provide a review of either, when I started on the CGI front there really weren't any of these available :-), oh how times have changed but not enough has changed in the CGI world to warrant getting them. http://danconia.org Al Hospers wrote: Perl Cookbook is a very good book too...

Re: arrays & lists
here is an example of MySQL code to pick a random
record using some select criteria. i use it in a
homepage for an online store where my client has
random items from his catalog displayed as "featured"
items (really nothing more than picking a random
record from the 10,000+ items!)...
$mysql_query="SELECT
UIN,EXTENDED_DESC,PIC_FILENAME,LOGO_ID,LIST_PRICE,UNIT
from $items_database order by rand() limit 1";

MySQL can do a lot of this for you, I believe...
You want a random record from the database and retrieve a particular field
from that record:
# Untested, but you would call this subroutine like so:
# getRandomRecord( $dbh, "SELECT field_Im_interested_in FROM $TABLE
# WHERE month like $month and day like $day" );
# NOTE: $sql (2nd parameter) can't already have a LIMIT in it, or any SQL
# statement which a LIMIT suffix would result in an invalid SQL statement.
sub getRandomRecord {
my( $dbh, $sql ) = @_;
my ( $sth, $randomNumber, $myValue );
$sth = $dbh->prepare( $sql );
$sth->execute;
$randomNumber = int(rand( $sth->rows ) );
$sth->finish;
# $randomNumber will be 0 <= $randomNumber < $sth->rows, which
# fits nicely with MySQL's LIMIT clause
( $myValue ) = $dbh->selectrow_array( $sql . " LIMIT $randomNumber,
1" );
return $myValue;
}

Re: multiple selection
Two things:
1) Your action parameter of the form tag was pointing to a separate program.
If you leave it blank (or leave it out altogether), then this same script
will process it.
2) You don't need to split param('list') - CGI.pm will automatically make an
array for you, if it contains multiple entries.

libwww example / tutorial
Hi,
Anyone know any URL about libwww example / tutorial?
I cant find decent source. I just want to learn how to GET an ouput from a website and
parse the
output.
from one of example, I can print the output like this :
if ($res->is_success) {
print $res->content;
} else {
print "Error: " . $res->status_line . "\n";
}
What is the variable type of $res->content ? is it Array? Because it just dumped the
output
(multiple lines), I need to parse line by line.
Thanks,
kapot
