Hello!

I have a strange thing going on. This is my perl code:
______________________________________
#! /usr/bin/perl
use CGI;
use DBI;

print "Content-type: text/html\n\n";
print "<HTML><HEAD><meta http-equiv=Content-Type content=text/html; charset=iso-8859-2><TITLE> Adding a NIC card name</TITLE></HEAD>";
print "<BODY BGCOLOR=EEEEEE>";

$username = 'root';$password = '';$database = 'arp';$hostname = '';
$dbh = DBI->connect("dbi:mysql:database=$database;" .
"host=$hostname;port=3306", $username, );

my $q=new CGI;
$MAC=$q->param("id");
#print "MAC: $MAC\n";

print "<HR>";
print "<H2><B><font color=\"#800000\"> All data about $MAC </font></B></H2>";



#creating HTML table
print "<BR><BR>";
print "<TABLE ALIGN=center WIDTH=50% BORDER=4 CELLSPACING=2 CELLPADDING=2>";

print "<tr> <th align=center valign=middle> MAC </th>";
print "<th align=center valign=middle> NIC name </th>";
print "<th align=center valign=middle> Computer name /th>";
print "<th align=center valign=middle> IP </th>";
print "<td align=center valign=middle> date </td>";
print "<td align=center valign=middle> time </td>";
print "</tr>";

$SQL="select * from table where MAC='$MAC' order by date";
$Select = $dbh->prepare($SQL);
$Select->execute();

while($Row=$Select->fetchrow_hashref)
{
print "<tr><td>$Row->{MAC} </a> <td>$Row->{NICname} <td>$Row->{CompName} <td>$Row->{IP} <td>$Row->{date} <td>$Row->{time}</tr>";

$mac1=$Row->{MAC};
$nameMAC=$Row->{NICname};
}

print "</TABLE>";

if ($NICname eq '')
{
print "<FORM action=\"/cgi-bin/NICname.pl\" method=post>";
print "<input type=text size=20 name=\"name\">";
print "<INPUT TYPE=submit NAME=submit value=\"Save\">";
print "</FORM>";
}

print "</BODY></HTML>";
______________________________________

When I check it from command line:
perl -wc myscript.pl
it says everything's ok.
But when I run it as html, I get Internal Server Error. And in Error_log file it says: malformed header from script. Bad header=name=myNIC&submit=Save: ...

Any ideas why this is happening and how to fix it?

instead of
Code: 
print "Content-type: text/html\n\n";
print the header using the CGI module.
Code: 
#! /usr/bin/perl
use CGI;
use DBI;

#print "Content-type: text/html\n\n";

$username = 'root';$password = '';$database = 'arp';$hostname = '';
$dbh = DBI->connect("dbi:mysql:database=$database;" .
  "host=$hostname;port=3306", $username, );

my $q=new CGI;
[COLOR=red]print $q->header();[/color]
#print "<HTML><HEAD><meta http-equiv=Content-Type content=text/html; charset=iso-8859-2><TITLE> Adding a NIC card name</TITLE></HEAD>";
print $q->start_html(-title=>'Adding a NIC card name',
               -style=>{'src'=>'/stylesheet/style.css'},
               -base=>'true',
               -target=>'_blank',
               -meta=>{'keywords'=>'pharaoh secret mummy',                   'copyright'=>'copyright 1996 King Tut'},
               -author=>'name or email address of author',
               -BGCOLOR=>'#EEEEEE');

Thanks for the advice, PaulTEG!

It was very helpful - it got me started. But I had to print the whole form using the CGI module, as well.

Now it's working. [thumbsup2]
