Login Error

[brmcdani]

I am trying to create a login for my webstie but I keep getting the following errors:

 

Warning: session_register() [function.session-register]: Cannot send session cookie - headers already sent by (output started at /home/mcdtech1/public_html/lubbockwebpro.com/checklogin.php:1) in /home/mcdtech1/public_html/lubbockwebpro.com/checklogin.php on line 26

I have looked at the lines it points out and am still having trouble here is my code:

 

<?php
ob_start();
$host="localhost"; // Host name 
$username="mcdtech1"; // Mysql username 
$password="l0608448533"; // Mysql password 
$db_name="mcdtech1_lakeAlanH"; // Database name 
$tbl_name="users"; // Table name 
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
// Define $myusername and $mypassword 
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
ob_end_flush();
?>

 

Any help would be appreciated. Thanks

You start output buffering at line 2. Why? That might be the problem. You cannot do header("location... while output buffering is on. So I suppose you have a good reason for output buffering, but if not, you might just want to remove that.

<?php
$host="localhost"; // Host name 
$username="mcdtech1"; // Mysql username 
$password="l0608448533"; // Mysql password 
$db_name="mcdtech1_lakeAlanH"; // Database name 
$tbl_name="users"; // Table name 
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
// Define $myusername and $mypassword 
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:login_success.php");
}
else {
ob_start();
echo "Wrong Username or Password";
ob_end_flush();
}
?>

Thanks for the reply, where does the {remove} go???  On the very bottom?  I made the changes and noticed the Remove on the post after.
