Do you mean -MCPAN or MCPAN?  Is it possible that root and the user that 
your are running mysql are using different Perls?

stylesheets

Hi,
Anyone know is it possible to place links to cascading stylesheets in perl
under apache? Is it possible to get perl  to use stylesheets?

Sure.  Just print out the link tag in the appropriate place in your 
ourput (so it appears in the <head> section):

 print qq!<link rel="stylesheet" href="mystyles.css" type="text/css" />!;

> Is it possible to get perl  to use stylesheets?

I'm not sure what you're getting at here.  In CGI, Perl is just used
to generate HTML.  After that, the browser does all the work.  Links
to images, stylesheets, javascript libraries, etc. are all followed
(and processed) by the browser, not by Perl (under standard CGI
circumstances). 

Hope that helps.

Placeholder question

I learned about placeholders/bind variables from this list and have been 
using them relatively successfully for a little bit now. However, the 
following query (a very simple one) doesn't work.
my $key='1';
my $name='mike';
$statement=<<"end";
update mentors set firstname=? where id=?;
end
$query=$dbh->prepare($statement);
$query->execute($name,$key) or die "Can't execute query: " . $dbh->errstr 
."\n";

#$query="update mentors set firstname='mike' where id=$key";
#$sth=$dbh->prepare($query);
#$sth->execute();

The commented query without placeholders works fine.  When I run it using 
the query that contains place holders I get this error:
DBD::mysql::st execute failed: You have an error in your SQL syntax near ';
' at line 1 at test.pl line 10.
DBD::mysql::st execute failed: You have an error in your SQL syntax near ';
' at line 1 at test.pl line 10.

Line 10 is the $query->execute($name,$key); line.  Any ideas?

Thanks,
Mike

Re: Placeholder question

Oops. It was the ; at the end of the $statement string...which is obvious 
now looking at the error.

A very easy mysql problem


I want to compare the password, which the user typed in (in a textfield) with a password, which is in a MySQL-db.

I tried the following:

	my $dbh = db_open("mypoll300903", "testuser", "authmysql");
	my $sth = $dbh->prepare("select password from table1 where prename = \"testprename\" and name = \"testname\";")
	    or die ($dbh->errstr);
	$sth->execute or die $sth->errstr;
	print "$sth";	
	$dbh->disconnect(); 

$sth is not yet what I want. It is something like the structure of what I need.

	I'd like to do the following:

	if ($passdb es $passusr) {   ## $passdb = the transformed $sth 
		$OK = 1;
	}

Any help will be greatly appreciated,

Thomas

Again a question


Hi all,

I'm trying still to programm a websurvey with saving the data in a db.

On the first page the user has to fill out a form (some radiobuttons).

I would like to store the results in my MySQL-db. On this first site there are 3 variables $Q1-$Q2 for 3 questions.

Now I tried the following:

	print "<form action='$url' method='post'>";
    	 	my $daten = { Q1 => $Q1,
 			      Q2 => $Q2,
 			      Q3 => $Q3};
	 	my $dbh = db_open("mypoll300903", "testuser", "authmysql");
 		$dbh->disconnect();
 		&eintrag($dbh, $daten);
		print "<input type='hidden' name='Site' value='3'>";
		print "<input type='submit' name='submit' value='Zur nächsten Frage'>";
      print "</form>";

With the error-message, that the variables $Q1... Requires explicit package name.

I produce the HTML-part in a subprogram, where the number of questions can be give as an argument.

Any ideas, how I could do what I want or where I could find a documentation about this 
(havn't found it in perldoc DBI)

Thanks a lot

Re: Again a question

Please don't hate me but you should read some tutorials first 
and get familiar with a few things about cgi and mysql.
maybe google will give you a clue ("tutorial cgi mysql").

are you sure that you retrieve the posted vars $Q1... 
correctly from the environment ?

why do you disconnect before storing data (&eintrag) ?

outputting the form and storing data in the
same code block looks a little bit strange to me.

sorry,
uli

After execution you must retrieve result records. Common way is:
my  <at> record;
while (  <at> record = $sth->fetchrow_array() )
{
 # here we have a result record in  <at> record
}

But as far as you expect only one record with only one field, you can perform 
it this way:

    my $dbh = db_open("mypoll300903", "testuser", "authmysql");
