undefined index when trying to get value from textbox

Question

I’m trying to get a value from a text box named name. however, when I'm trying to get the value, it says, name is an undefined index:

<form method="get">
    <input type="text" name="name">
    <input type="submit" value="Submit">
</form>

<?php 

$name = $_GET['name'];

?>

When using code inside the same page, use `isset()` along with a conditional statement. — Funk Forty Niner, Jun 04 '14 at 03:16
upon execution, `$_GET['name']` is undefined, unless you accessed the url as `http://yoursite.com?name=myname` — user1978142, Jun 04 '14 at 03:16

$_GET['name'] will be undefined until the form gets submitted so use this

<form method="get">
    <input type="text" name="name">
    <input type="submit" value="Submit" name="submit">
</form>

<?php 

if (!empty($_GET))
    $name = $_GET['name'];
?>
