Topic: username and password verification
hi all,
my database name is "test".in the "test" database
i have created a table name called "log" which has two fields
namely username and password.
i have given username as "admin" and password as "admin123".
now i have written one code using php so that when i click the submit button both the username as admin and password as admin123 gets matched then it should direct to the next page...
tell me how to check whether username and passwords are matching and if it matches it must point to the action part what we give in <form method="POST" action="www.php">
kindly tell me what i must add to the below program.....
below is the code in php......
<?php
$host="localhost";
$username="root";
$password="";
$db_name="test";
$tbl_name="log";
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$myusername = stripslashes($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";
}
?>
