split large flatfile into numbered pages?

[kellypayton]

Hey,

Can anyone explain to me how i can take all the info from a flatfile but split it into pages??. For example I have a file containing a list of 1000 games(line by line), instead of having all 1000 displayed on the screen at the same time..how can i split it into say pages with 100 games on each?.

output example: It displays the first 100 lines from the flatfile and then when i click page 2 it displays the next 100..and so on.

You can use the query string to provide a "start" value, like "list.cgi?start=200" and go on a for loop through the array to get a list of just the ones you want to show.

my $start = $cgi->param ('start');
my $end = $start + 100;

my @showOnPage = ();
for (my $i = $start; defined $gameArray[$i] && $i <= $end; $i++) {
   push (@showOnPage, $gameArray[$i]);
}

# @showOnPage now would contain, say,
# games 200 to 300 from the array
# @gameArray

You could then check the positions of the previous and next positions in @gameArray to determine if a "Previous Page" or "Next Page" link should be used, or divide up the scalar(@gameArray) to get a list of actual page numbers you could link to.

It's a little more complicated then that if you want the next/prev/page-number links on the page to click on. But you could use Kirsle's code to build a page break routine on. There are a couple of modules that create page breaks but you would need to install them.
