Why are my form variables not passing through POST?

Question

I am sending form data through POST, but the corresponding POST variables are not set, and do not.

Also, when I store POST data into local PHP variables, I seem to be unable to use those variables. (Once I resolve the first issue, I have a feeling I will be able to user the variables too.)

My error messages output by the second page (see below) is:

Notice: Undefined variable: postUsername in (...somepath)\scripts\create-member.php on line 10

(Form page) :

<form action="scripts/create-member.php" method="POST">

        <input type="text" name"username" value="" placeholder="User Name"> <br />
        <input type="password" name"password" value="" placeholder="Password"> <br />
        <input type="password" name"passwordConfirm" value="" placeholder="Confirm Password"> <br />
        <!-- ?type email or type text -->
        <input type="email" name"email" value="" placeholder="Email" autofocus> <br />
        <input type="submit" name="submitRegistration" value="Register!">

    </form>

(Second page) scripts\create-member.php:

<?php

//!proper way to declare variables obtained from POST.
// Data from form "register.php"
if ( isset($_POST['username']) ) {
    $postUsername = $_POST['username'];
}


echo $postUsername;    // <-- this is line 10

?>

I've tried using isset() for the submit button too, but that didn't solve the problem. I've simplified the code by a lot here, and ran it testing it too.

the form tag was there, but stackoverflow needed me to put in another line break for it to show. — ahnbizcad, Nov 24 '13 at 13:19
I tried echoing a literal string. It actually echos nothing. — ahnbizcad, Nov 24 '13 at 13:21
Put `=` in `name"password"`, `name"username"`, `name"passwordConfirm"` etc... — MeNa, Nov 24 '13 at 13:21
^ oh my. how embarassing. I knew it would be something like that. I tried checking so many other things, but this is what gets me. thank you for the second set of eyes. — ahnbizcad, Nov 24 '13 at 13:23
@gwho5150 A HTML validator would have saved you from this embarassment. — Oswald, Nov 24 '13 at 13:28

In your html code, you have missed = for name

name="username"

Instead of name"username"

Here's your fixed code.

<input type="text" name="username" value="" placeholder="User Name"> <br />
<input type="password" name="password" value="" placeholder="Password"> <br />
<input type="password" name="passwordConfirm" value="" placeholder="Confirm Password"> <br />
<!-- ?type email or type text -->
<input type="email" name="email" value="" placeholder="Email" autofocus> <br />

the ploblem is not at register.php

you can try to write like this:

if ( isset($_POST['username']) ) {
$postUsername = $_POST['username'];
echo $postUsername;
}

I had a similar problem posting to an index.php file in a folder.

<form id="register" name="register" method="POST" action="/register">
// BROKEN

all $_POST vars were empty until I added a trailing forward slash to the form post action

<form id="register" name="register" method="POST" action="/register/">
// WORKS

Why are my form variables not passing through POST?
