i created a database named as 'db' in myphpadmin. I created a login page. but i could not connect with my database.
I'm using the following codings:
<?php
ob_start();
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="db"; // Database name
$tbl_name="login"; // Table name
// Connect to server and select databse.
mysql_connect("$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();
?>
The output of the above coding will be
cannot select DB
Please anyone help me
