Help With Meta Search
|
Can't Post
|
|
Hello,
I was wondering if someone could help me out. I have had this meta search engine running on my site for a while now, and it all of a sudden won't work anymore. This is the coding I am using, I would appreciate some help, it has been driving me insane :)
This is what I have without the Form html
-------------------------------------------------
&data_parse;
&main;
sub main{
$| = 1;
if ($FORM{'q'} eq '')
{
&show();
exit;
}
&IOSocket;
$output = join(" ", @output);
$output =~ /([^ ]*?) pages found\./i;
$total = $1;
$total =~ s/[^\d+]//g;
($rsltpgs, @results, $footer) = split(/<dl>/i, $output);
$FORM{'nh'} = 0 unless($FORM{'nh'});
$prev = $FORM{'nh'} - 10;
$next = $FORM{'nh'} + 10;
$rsltpgs = qq~<p><font size=-1><b>Results Pages:\ </b>~;
$rsltpgs .= qq~<a href="$ENV{'SCRIPT_NAME'}?q=$query&nh=$prev&user=$FORM{'user'}">[<b>\<\< Prev</b>]</a>~ if ($prev >= 0);
$Remainder = $total % 10;
$Remainder = 10 - $Remainder;
$Results_Pages = ($total + $Remainder) / 10;
$Results_Pages = 20 if ($Results_Pages > 20);
for ($i = 1; $i <= $Results_Pages; $i++)
{
$nh = ($i - 1) * 10;
if ($nh == $FORM{'nh'})
{
$rsltpgs .= qq~\ \ <b>$i</b>\ ~;
}
else
{
$rsltpgs .= qq~\ \ <a href="$ENV{'SCRIPT_NAME'}?q=$query&nh=$nh&user=$FORM{'user'}">$i</a>\ ~;
}
}
$rsltpgs .= qq~\ \ <a href="$ENV{'SCRIPT_NAME'}?q=$query&nh=$next&user=$FORM{'user'}">[<b>Next \>\></b>]</a>~ if ($next < $total && $FORM{'nh'} < 190);
$rsltpgs .= qq~</font>
~;
$start = $FORM{'nh'} + 1;
$end = $start + 9;
$end = $total if ($end > $total);
$output = "<font face=arial size=2><b>Showing results $start - $end of $total</b>
Results Provided By <a href=http://www.altavista.com>Altavista</a></font>$rsltpgs<ul>\n";
my $last = $#results - 1;
for(0..$last){
($result) = split(/<\/dl>/i, $results[$_]);
$result =~ s/\[[^\]]\]//ig;
$result =~ /<a\s+href=\"([^\"]*?)\">/ig;
$url = $1;
($tmp, $title) = split(/\">/i, $result);
($title, $tmp) = split(/<\/a>/i, $title);
($ttp, $desc) = split(/<dd>/i, $tmp);
($desc, $tmp) = split(/
/i, $desc);
$output .= qq~<li><a href="$url">$title</a> - $desc<p>\n~;
}
$output .= qq~</ul>$rsltpgs~;
&show($start,$stop,$command,$input,$output,$special);
}
sub IOSocket{
use IO::Socket;
$method = "GET";
my @f = split(/\//, $input);
$host = "www.altavista.com";
$path = "/sites/search/web?q=$query&pg=q&text=yes&kl=XX&stq=$FORM{'nh'}&search=Search";
$socket = new IO::Socket::INET( PeerAddr => $host,
PeerPort => 80,
Proto => 'tcp',
Type => SOCK_STREAM, ) or die &show($start,$stop,$command,$input,"<p>Error: Unable to connect to search server<p>",$special);
print $socket "$method $path HTTP/1.0\nReferer: $host\n";
print $socket "User-Agent: $ENV{'HTTP_USER_AGENT'}\n\n";
@output = <$socket>;
close ($socket);
}
sub data_parse{
if ($ENV{"REQUEST_METHOD"} eq 'GET') {
$buffer = $ENV{'QUERY_STRING'};
}
else {
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
}
@pairs = split(/&/, $buffer);
foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
if ($name eq 'q'){ $query = $value; }
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$value =~ s/>//g;
$value =~ s/<//g;
$FORM{$name} = $value;
}
$FORM{'q'} = $FORM{'search'} if $FORM{'search'};
}
Thanks for the help.
