can't show user's information

KC8Alen · April 14, 2010

Hi, I have a problem with a PHP webpage i made, the problem is

It doesnt show the data from the user, I've looked at it for one and a half days already but I can't seem to find the problem, it doesn't echo or print the value it gets from the database.

The data it retrieves actually should be printed out on the page, but currently i'm trying to have it print in textbox value, it doesn't really matter whether its printed/echoed in textbox or not.

Here is the code:

<?PHP 
session_start();

mysql_connect("localhost", "username") or die(mysql_error()); 
mysql_select_db("Survey") or die(mysql_error()); 

//checks cookies to make sure they are logged in 
if(isset($_COOKIE['ID_my_site'])) 
{
	$username = $_COOKIE['ID_my_site']; 
	$pass = $_COOKIE['Key_my_site']; 
	 	$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error()); 
	while($info = mysql_fetch_array( $check )) 	 
	{
	if ($pass != $info['password']) 
		{ 			
	header("Location: login.php"); 
		}
}
}
?>

Hope someone can help me out, thanks a lot.

The line

$num=mysql_numrows($result);

should be

$num = mysql_num_rows($result);

This code

$result=mysql_query($check);
$num=mysql_numrows($result);

$i=0;
while ($i < $num)
{
$username=mysql_result($result,$i,"username");
$bnaam=mysql_result($result,$i,"Bedrijfsnaam");
$kvk=mysql_result($result,$i,"Kvknr");
$tel=mysql_result($result,$i,"Telefoonnummer");
$email=mysql_result($result,$i,"Emailadres");
$contpers=mysql_result($result,$i,"Contactpersoon");
$adres=mysql_result($result,$i,"Adres");
$jaar=mysql_result($result,$i,"Jaar_van_oprichting");
$pcode=mysql_result($result,$i,"Postcode");
$plaats=mysql_result($result,$i,"Plaats");
$i++;
}

should also be within the

if(isset($_COOKIE['ID_my_site']))

statement, otherwise $check may not be declared and you will get a T_UNDEFINED_VARIABLE error.

I also failed to mention that you don't need to open a new MySQL connection twice in the same script unless you use the function mysql_close() on a MySQL handler.

I also noticed you haven't included a password in the mysql_connect() function, unless you just left this out to post your code here?

thnx for your reply, but i've delete that part and replaced something else with it, so i didnt declare every column, and looks like its working

But thank you for pointing me that out =D

KC8Alen · April 14, 2010

yups i deleted that part already about the 2 opening mysql, because i went freak so i tried to set 2 mysql opening and hope it worked... lol for the password, i dont have a password for the mysql yet, and when i put password I get error, but im still running it local only,

thanks
