in thread DB search results using DBI...execute

Try this simple cgi to show the benefit of using Dumper.

#!perl # Dumper demo cgi use strict; use Data::Dumper; print "Content-Type: text/html\n\n"; print '<pre>'; my $ref = [ { ID => 'ABC'},{ ID => 'DEF'},{ ID => 'GHI'} ]; print '<h2>$ref</h2>'; print Dumper $ref; print '<hr/>'; my @array = map { $_->{ID} } @$ref; print '<h2>@array</h2>'; print Dumper @array; print '<hr/>'; my @error = @array."\n"; print '<h2>@error</h2>'; print Dumper @error; print '<hr/>';

Also, note how map could be used to replace this code in search_item()

my @array = @$resultsRef foreach my $hit (@array) { # $hit is a hash reference. my %hash = %$hit; push @searched, $hash{ID}; }
