Retrieve password from a html-form

I have a html-form which looks like this:

<form action="lib/AdminPage.php" method="post" id="adminLogin">
Admin-Login: <input type="password" name="pw" v开发者_JS百科alue="" class="pw">
<input type="submit" value="Login">

AdminPage.php contains the following lines:

      <?php


    echo($_GET['pw']);
    echo($_GET['adminLogin']);
    echo($_GET['Login']);
    echo($_GET['id']);
    echo($_GET['value']);
    echo($_GET['name']);

    echo($pw);

    echo($_GET["pw"]);
    echo($_GET["adminLogin"]);
    echo($_GET["Login"]);
    echo($_GET["id"]);
    echo($_GET["value"]);
    echo($_GET["name"]);

?>

None of the echoes works, it's always an "Undefined index" or "Undefined variable" with echo($pw)

How can I retrieve the entered string from the from?

Use $_POST instead of $_GET, because you have method="post" in your form.

You are sending the form using POST but looking for GET variables. Replace $_GET with $_POST.

Since you have method="post" in your form <form action="lib/AdminPage.php" method="post" id="adminLogin">, variables are accessed as _POST variables. So, you should do

echo $_POST['pw'];

All you need to do is this:

echo $_POST['pw'];

Your HTML form has method="post" in it so you get all information from inputs via $_POST instead of $_GET.

use the $_POST array, not $_GET

Your form uses the POST HTTP method, hence this should work.

echo($_POST['pw']);
echo($_POST['adminLogin']);
echo($_POST['Login']);
echo($_POST['id']);
echo($_POST['value']);
echo($_POST['name']);

You need to post the values. But, you are trying to get those through $_GET.

Try changing everywhere $_GET by $_POST

Change like this :

echo($_POST['pw']);
echo($_POST['adminLogin']);
echo($_POST['Login']);
echo($_POST['id']);
echo($_POST['value']);
echo($_POST['name']);
