Notice: Undefined index: submit in C:\wamp\www\matri\login.php

[anshu]

Hello,

 

I am new to PHP and trying to make thelogin page for my admin panel. 

 

My login page code is:

 

<?php

require_once('dbadmin.php');

$error = '';

$form = $_POST['submit'];

$email = $_POST['email'];

$password = $_POST['password'];

 

if( isset($form) )

{

if( isset($email) && isset($password) && $email !== '' && $password !== '' ) 

{

$sql = mysql_query("SELECT * FROM `marti_admin` WHERE username='$email' and password='$password';");

if( mysql_num_rows($sql) != 0 )

{ //success

$_SESSION['logged-in'] = true;

header('Location: data_insert.php');

exit;

 

} else { $error = "Incorrect login info"; }

 

} else { $error = 'Username/Password Incorrect';}

 

}

?>

 

 

///////html code//////

 

But i got these errors

 

( ! ) Notice: Undefined index: submit in C:\wamp\www\matri\login.php on line 4 Call Stack # Time Memory Function Location 1 0.0014 373944 {main}( ) ..\login.php:0
( ! ) Notice: Undefined index: email in C:\wamp\www\matri\login.php on line 5 Call Stack # Time Memory Function Location 1 0.0014 373944 {main}( ) ..\login.php:0
( ! ) Notice: Undefined index: password in C:\wamp\www\matri\login.php on line 6 Call Stack # Time Memory Function Location 1 0.0014 373944 {main}( ) ..\login.php:0
 

 

 

Please help me in removing these errors...

You're doing the isset() test too late.

 

You should assign the variables like this:

if(isset($_POST['submit'])){
    $form = $_POST['submit'];
}
//And the same with email and password.

(or on one line)

$form = isset($_POST['submit']) ? $_POST['submit'] : NULL;

That will clear up your undefined index errors. And the reason you're getting the errors is most likely because the form that is submitting to this script either isn't passing the variables through with the same name, or the fields haven't been filled out in the form.

 

Hopefully that'll help you out.

Now i got errors:

 

 ( ! ) SCREAM: Error suppression ignored for( ! ) Parse error: syntax error, unexpected $end in C:\wamp\www\matri\login.php on line 74

That is a simple syntax error which you need to learn to resolve yourself.

 

If you can't, we need to see the relevant code.

[denno020]

trq is right.. You'll need to bring all of your code here, and highlight which line 74 is.. In the process of doing that though, you'll see where the error is and probably be able to figure out the solution yourself.
