You need to keep track of two things: where to start, and
how many to show.
First set $start to one unless we're getting a param.
unless(param('start')){ $start = 1 }
Then use two counters to track where to start and how many
to process.
for(@array){
$c++; # count all items
if($c >= $start){ # if $c count is = or greater than where to star
+t
$d++; # count items that match first test
unless($d > $show){ # unless $d count is greater than how many
+ to show
print # or whatever
}
}
}
Then calculate the 'previous n' and 'next n' links.
$previous = ($start-$show);
unless($previous < 1){ # unless we're already at the beginning
print qq~<a href="$url?start=$previous&show=$show">
Previous $show</a>~;
}
$next = ($start+$show);
unless($next > $c){ # unless we're already at the end
print qq~<a href="$url?start=$next&show=$show">
Next $show</a>~;
}
