sorting
i wanted to sort by Rating, inhits, isnew, iscool here's the following codes i'm using, at links.def i set it to db_sort_links w my rating field, the links are currently sorted from highest Rating to lowest rating, but now i wanted it to sort by "Rating, inhits, isnew, iscool"


sub build_sorthit {
# --------------------------------------------------------
# This function sorts a list of links. It has been modified to sort
# new links first, then cool links, then the rest alphabetically. By modifying
# the sort function below, you can sort the links however you like (by date,
# or random, etc.).

my (@unsorted) = @_;
my ($num) = ($#unsorted+1) / ($#db_cols+1);
my (%sortby, %inhits, %isnew, %iscool, $hit, $i, @sorted, $column, $type);

foreach $column (@db_cols) {
if ($db_sort_links == $db_def{$column}[0]) {
$type = $db_def{$column}[1];
last;
}
}
for ($i = 0; $i < $num; $i++) {
$sortby{$i} = $unsorted[$db_sort_links + ($i * ($#db_cols+1))];
($unsorted[$db_isnew + ($i * ($#db_cols+1))] eq "Yes") and ($isnew{$i} = 1);
($unsorted[$db_ispop + ($i * ($#db_cols+1))] eq "Yes") and ($iscool{$i} = 1);
}
if ($type eq "date") {
foreach $hit (sort {

&date_to_unix ($sortby{$b}) <=> &date_to_unix ($sortby{$a});
} (keys %sortby)) {
$first = ($hit * $#db_cols) + $hit;
$last = ($hit * $#db_cols) + $#db_cols + $hit;
push (@sorted, @unsorted[$first .. $last]);
}
}
elsif ($type eq "numer") {
foreach $hit (sort {
$sortby{$b} <=> $sortby{$a};
} (keys %sortby)) {
$first = ($hit * $#db_cols) + $hit;
$last = ($hit * $#db_cols) + $#db_cols + $hit;
push (@sorted, @unsorted[$first .. $last]);
}
}
else {
foreach $hit (sort {
($isnew{$b} and !$isnew{$a}) and return 1;
($isnew{$a} and !$isnew{$b}) and return -1;
($iscool{$b} and !$iscool{$a}) and return 1;
($iscool{$a} and !$iscool{$b}) and return -1;
($isnew{$a} and $isnew{$b}) and return lc($sortby{$a}) cmp lc($sortby{$b});
($iscool{$a} and $iscool{$b}) and return lc($sortby{$a}) cmp lc($sortby{$b});
return lc($sortby{$a}) cmp lc($sortby{$b});
} (keys %sortby)) {
$first = ($hit * $#db_cols) + $hit;
$last = ($hit * $#db_cols) + $#db_cols + $hit;
push (@sorted, @unsorted[$first .. $last]);
}
}
return @sorted;
}
