All of a sudden my php code has come up with :



Notice: Undefined index: submit in C:\xampp\htdocs\globalautoparts\register.php on line 36



Notice: Undefined index: fullname in C:\xampp\htdocs\globalautoparts\register.php on line 40



Notice: Undefined index: username in C:\xampp\htdocs\globalautoparts\register.php on line 41




Notice: Undefined index: password in C:\xampp\htdocs\globalautoparts\register.php on line 42



Notice: Undefined index: repeatpassword in C:\xampp\htdocs\globalautoparts\register.php on line 43



Notice: Undefined index: email in C:\xampp\htdocs\globalautoparts\register.php on line 45

";
$submit = $_POST['submit'];



//form data
$fullname = strip_tags($_POST['fullname']);
$username = strtolower(strip_tags($_POST['username']));
$password = strip_tags($_POST['password']);
$repeatpassword = strip_tags($_POST['repeatpassword']);
$date = date("Y-m-d");
$email = $_POST['email'];

if ($submit)
{


//open database
$connect = mysql_connect("localhost","root","");
mysql_select_db("phplogin"); //select database

$namecheck = mysql_query("SELECT username FROM users WHERE username='$username'");
$count = mysql_num_rows($namecheck);

if ($count!=0)


{
die("Username already taken! Go back to try again?");

}

// check for existence
if($fullname&&$username&&$password&&$repeatpassword)
{



if ($password==$repeatpassword)
{

//check char length of username and fullname
if (strlen($username)>25||strlen($fullname)>25)
{
echo "Length of username or fullname is too long!";


}


else{
//check password length
if (strlen($password)>25||strlen($password)<6)
{
echo "Password must be between 6 and 25 characters";
}
else{
//register the user!


// encrypt password
$password = md5($password);
$repeatpassword = md5($repeatpassword);


//generate random number for activation process
$random = rand(23456789,98765432);
$queryreg = mysql_query("

INSERT INTO users VALUES ('','$fullname','$username','$password','$email','$date','$random','0')


");

$lastid = mysql_insert_id();


//send activation email
ini_set("SMTP",$server);
$to = $email;
$subject = "Activate your account!";

$headers = "From: Global Auto Parts";
$server = "localhost";





$body = "

Hello $fullname,\n\n


You need to activate your account with the link below:

http://localhost/globalautoparts/activate.php?=$lastid&code=$random \n\n


Thanks.

";


//function to send mail
mail($to, $subject, $body, $headers);

die("You have been registered! Check your email to activate your account!");
}


}
}
else

echo "Your passwords do not match!";

}
else
echo "Please fill in all fields!";




}

Answer



As the other guys suggested, you could



Change the Error Reporting Level




By running this code at the top of your script: error_reporting(E_ALL ^ E_NOTICE)



Or, it might be a better idea to actually check whether those variables were posted before you use them.



Quick and Dirty fix is to do this:



@$_POST['submit']


The @ sign will suppress any errors and return false in place of the string. Now that practice is generally frowned upon.




If you want a cleaner method, I would do this:



$post = array('fullname'=>'','username'=>'','password'=>'','repeatpassword'=>'');

if($_POST) $post = array_merge($post, $_POST);

$fullname = strip_tags($post['fullname']);
$username = strtolower(strip_tags($post['username']));

$password = strip_tags($post['password']);
$repeatpassword = strip_tags($post['repeatpassword']);


Then you'll never have a error about missing indexes, and you can set the default values to whatever you like.



Good luck
