in reply to Page Links...

Hi ,

The theortical approach would be by :

First get the rows twenty ($start_limit) starting from a variable that is supplied by a flag when it is the first page or a hidden parameter that can be supplied by the submission of next button at the end of the page for all the other pages .

The page is count incremented for this set

# Just a sample to indicate the flow (untested) my $pages = $cgi->param{'pages'}||1; my $start_limit = shift|| $cgi->param {'start_limit'}; # Get the record info starting from the # $start_limit record and the twenty from it # print "the records \n"; # print "the $pages at the end of the page "; $start_limit += $start_limit; $pages += $pages; # ALSO pass $start_limit and $pages as the hidden paramete +rs to the page occuring next to this


This is just to give an idea of what should be a navigation scheme through maintaining hidden parameters between pages and also the part of select to get the rows within a range which is $start_limit to $start_limit + 20 is done by rownum in oracle and if that is different process it in the perl with $start_limit parameter .The present application which you have written should be posted so that any constructive suggestions could be discussed . Also go through the CGI::FormBuilder API from the CPAN that shall give you some idea to maintain state too among pages , these are just a few suggestions
