Question

Hey i get this : Notice: Undefined index: in C:\\wamp\\www\\tests\\Joomla\\Website\\index.php on line 37

And my code is this :

<?php 
    $remarks=$_GET['remarks'];

    if ($remarks==null and $remarks=="")
    {
        echo '';
    }
    if ($remarks=='success')
    {
        echo 'Registration Success';
    }
?>

I don't understand why i get this . Please help!

Answer 1

First, you don't say where is the line 37... I ain't a wizard, but I can guess from the error...

Since the error is Undefined index , that must come from the line:

$remarks=$_GET['remarks'];

You should validate that $_GET['remarks'] is not null with isset($_GET['remarks']) before trying to get it's value.

Second, that line does not make any sence, since the $remarks can never be null and "" :

 if ($remarks==null and $remarks=="")

So I would write the code like this:

<?php 
    $remarks = "";
    if ( isset($_GET['remarks']) ) {
        $remarks = $_GET['remarks'];
    }

    if ( $remarks == 'success' ) {
        echo 'Registration Success';
    }
?>
