I am "trying" to get this to work, but I can't seem to
find an answer in either the cookbook or programming
perl. What I would like to do is randomize an entire
array of jpgs in a database of about 50, then take 20
or so and print them out to a template page.
What happens is that it puts ONE picture on the page,
20 times, instead of 20 thumbnails once each.
Could you please help a newkid out ?
Here is what I sometimes refer to as my "code".
#!/usr/bin/perl -w
print "Content-type: text/html\n\n";
$dir = "/home/usr/public/images/";
$view = "view.html";
$number_to_show = 15;
$title = "Your Title Could Go Here";
srand( time() ^ ($$ + ($$ << 15)) );
opendir DIR, "$dir";
my @arr = grep -f, grep /\.jpg$/i, map "$dir/$_", readdir DIR;
$n = @arr;
foreach (reverse 0..$n) {
my $pic = splice(@arr, rand $n, 1);
push @arr, $pic;
$#arr = $number_to_show;
}
&print_it();
sub print_it {
open (PAGE, "$dir$view") || die ("I am unable to open the template $vi
+ew");
while (<PAGE>) {
s/%%title%%/$title/g;
s/%%images%%/@arr/g;
print $_;
}
close (PAGE);
}
