The code should look something like this:
my @outer;
while (my $rows1 = $query1->fetchrow_hashref()) {
my $query2 = &db_query("SELECT title FROM pages WHERE sectionid = $
+sectionid");
$inner=[]; # you need a NEW array for each loop, not just an empty
+ array
while (my $rows2 = $query2->fetchrow_hashref()) {
push(@$inner,{TITLE=>$rows2->{title});
}
push(@outer,{
TITLE=>$rows1->{title},
PAGES=>$inner;
});
}
$template->param(sections=>\@outer);
The most common mistake with this problem (it bites everybody at least once) is assigning an empty
array instead of an empty
array reference in the inner loop. If you make that mistake, the values for all the inner loops end up the same.
