create the database create the table in Mysql database. In the database table we create three fields
id, user_name and password. After create
the table insert value in username and password. Your database is ready to use.
login_action.php
<?php
ob_start();
mysql_connect("localhost", "root", "password");
mysql_select_db("databasename");
if(isset($_POST['login']))
{
$user_name = $_POST['user_name'];
$password = $_POST['password'];
$login = "select * from tablename where user_name=
'$user_name' && password=
'$password' ";
$exe = mysql_query($login);
$rows = mysql_num_rows($exe);
if($rows == 1)
{
echo "Login Successfully";
}
else
{
echo "Invalid
Username/Password";
}
}
?>
After create the
HTML login form we create the login_action.php page. In the login action page
firstly we start php
script for connecting the database table using php script. When user fill
the user name and
password text fields and click on login button. The login_action.php page
will be open. If your username and password is true login successfully message display on
the your screen. If
your username and password not matched invalid username and password
