Hi!

Have this function in my php file:

function brukerident($bruker_ID)
{
        $uuk = mysql_real_escape_string($_COOKIE["uuk"]);
        $sql = "SELECT Bruker_id FROM brukere WHERE uuk = '$uuk' LIMIT 1";
        $res = mysql_query($sql);
        
        // IF THE QUERY SUCCEEDED
        if ($res)
        {
            // THERE SHOULD BE ONE ROW
            $num = mysql_num_rows($res);
            if ($num)
            {
                // RETRIEVE THE ROW FROM THE QUERY RESULTS SET
                $row = mysql_fetch_assoc($res);

                // STORE THE USER-ID IN THE SESSION ARRAY
                return $row["Bruker_id"];
          
            }
        }
}

Open in new window


This function is called from a another php file:

 $brukerID = brukerident('xxx');

Open in new window


And i have tested that the returnd value is correct.

Value from database is a varchar..

But get an error message from this line:
$result3 = mysql_query("SELECT Navn FROM {$table1} WHERE Bruker_id={$brukerID}") or die(mysql_error());

Open in new window


Error message is:
Unknown column 'K007' in 'where clause'

What is wrong ?

What is Navn Data type ?? did you test printing the query.
break the sql to
echo $q="SELECT Navn FROM {$table1} WHERE Bruker_id={$brukerID}";
$r=mysql_query($q) or or die(mysql_error());

Open in new window

I think if the value is varchar insert Bruker_id='$brukerID'

and in your above function why do you are passing parameter $bruker_ID which is not using anywhere in function?

function brukerident($bruker_ID)
{
        $uuk = mysql_real_escape_string($_COOKIE["uuk"]);
        $sql = "SELECT Bruker_id FROM brukere WHERE uuk = '$uuk' LIMIT 1";
        $res = mysql_query($sql);
        
        // IF THE QUERY SUCCEEDED
        if ($res)
        {
            // THERE SHOULD BE ONE ROW
            $num = mysql_num_rows($res);
            if ($num)
            {
                // RETRIEVE THE ROW FROM THE QUERY RESULTS SET
                $row = mysql_fetch_assoc($res);

                // STORE THE USER-ID IN THE SESSION ARRAY
                return $row["Bruker_id"];
          
            }
        }
}

Where is K007 coming from, it's not present in your queries above.

Hi!

The function returns correctly..
Have tested this by using echo...

Tested the output from the query :
SELECT Navn FROM Kontroller WHERE Bruker_id=K007

And that is correct ?

Hi!

The problem was that i must use ' like this:
$result3 = mysql_query("SELECT Navn FROM {$table1} WHERE Bruker_id='{$brukerID}'") or die(mysql_error());

Your error is related to table field
Unknown column 'K007' in 'where clause'
can you fetch the record using above query?
SELECT Navn FROM Kontroller WHERE Bruker_id=K007

Open in new window

I suggest you to use single quote in value like:
SELECT Navn FROM Kontroller WHERE Bruker_id='K007'

Open in new window
