hi
I have a login form, when i tried to login i got this two errors:
Notice: Undefined index: username in C:\wamp64\www\FormTutorial\php\luana_login.php on line 6
Notice: Undefined index: password in C:\wamp64\www\FormTutorial\php\luana_login.php on line 7
I have been busting my head to figure out how to solve it so I went online to see if I can find a solution to fix the errors and I came across. I dont know how effective it is so
I have decide to give a tried to see how it work but this things when i put in my codes the errors gone but it give me a blank page when it should have give me the login form
to which i should be able to login.
this is the codes that I tried to use:
$username = @mysql_real_escape_string($_POST['user_name']);//when i add the code the errors is gone but give me a blank
$password = @mysql_real_escape_string($_POST['password']);
this is my codes below for the login form
<?php
// capture values from the form and store in php variables
$uname=($_POST['username']);
$pword=($_POST['password']);
//connection to the database
$db_host='localhost';
$db_username='root';
$db_password="";
$con=mysqli_connect($db_host, $db_username, $db_password) or die (mysqli_connect_error());
//select the database to query
mysqli_select_db($con, 'staff') or die (mysqli_error($con));
$sql="SELECT * FROM applicant WHERE uname ='$uname' AND pword=md5('$pword')";
$result=mysqli_query($con,$sql) or die ("Error:" .mysqli_error($con));
$rowcount=mysqli_num_rows($result);
if($rowcount == 1)
{
session_start();
$_SESSION['user']=$username;
header("location:luana_profile.php");
}
else
{
echo"<script type=\"text/javascript\">
alert('username and password doesn't exist');
window.location\"../xhtml/luana_login.html\";
</script>";
}
mysqli_close($con);
?>how is that possible, what can i do to fix it or tell me what did i do wrong or is the codes is correct one to use
