PHP：获取TEXTBOX的值然后将其传递给VARIABLE

My Problem is:

I want to get the value of textbox1 then transfer it to another page where the value of textbox1 will be appeared in the textbox2.

Below is my codes for PHP:

<html>
<body>

<form name='form' method='post' action="testing2.php">

Name: <input type="text" name="name" id="name" ><br/>

<input type="submit" name="submit" value="Submit">  

</form>
</body>
</html>

I also add the code below and the error is "Notice: Undefined index: name"

<?php 
$name = $_GET['name'];
echo $name;
?>

or

<?php 
$name = $_POST['name'];
echo $name;
?>

    In testing2.php use the following code to get the name:

    if ( ! empty($_POST['name'])){
    $name = $_POST['name']);
}

    When you create the next page, use the value of $name to prefill the form field:

    Name: <input type="text" name="name" id="name" value="<?php echo $name; ?>"><br/>

    However, before doing that, be sure to use regular expressions to verify that the $name only contains valid characters, such as:

    $pattern =  '/^[0-9A-Za-zÁ-Úá-úàÀÜü]+$/';//integers & letters
if (preg_match($pattern, $name) == 1){
    //continue
} else {
    //reload form with error message
}
