Hey now i have this but when i register only the index.php page shows up. Without the success message. When the registry is completed i redirected to index.php?msg=1 so that's in my opinion correct?

<?php 

if (isset($_GET['msg'] == 1)) {

echo "You have successfully registered.";

}

require_once('connect.php');

$errors = array();

if (isset($_POST['submit'])) {

if(empty($_POST['username'])){ array_push($errors, 'You did not submit a username'); }

$old_usn = mysqli_query($connect, "SELECT id FROM users WHERE name = '".htmlentities($_POST['username'], ENT_QUOTES)."' LIMIT 1;") or die(mysqli_error());
if (mysqli_num_rows($old_usn) > 0) { array_push($errors, 'This username is already registered.'); }


if (sizeof($errors) == 0) { 

$username = htmlentities($_POST['username'], ENT_QUOTES);
$email = htmlentities($_POST['email'], ENT_QUOTES);

mysqli_query($connect, "INSERT INTO users (name, hashed_pw, email, joined)
VALUES ('{$username}', '{$password1}', '{$email}', NOW());") or die ($connection_error);

header('Location: index.php?msg=1');

}

}

?>

The issue is here:

if (isset($_GET['msg'] == 1)) {  // These are two different conditions, you have to separate them by using &

change it to:

if ( isset($_GET['msg']) && $_GET['msg'] == 1 ) {

and try again.

Your code is not safe at all, use prepared statement and store the hash password instead of plain one.

if (isset($_GET['msg'] == 1)) that isn't the proper way to do this, since it will always be considered as being set.

You need to separate those into two conditions.

Such as:

if (isset($_GET['msg']) && $_GET['msg'] == 1)

I highly suggest you use a prepared statement though and password_hash().

What you have now, isn't safe at all.

If you do plan on going that route (which I hope you do), then please read over those manuals attentively for password_hash() and password_verify():

Note: You appear to have a missing variable set for $password1, so make sure it has value, otherwise your query will fail.

Also, mysqli_error() requires a database connection argument for it.

  • mysqli_error($connect)

This line or die ($connection_error) will throw you an undefined variable error, least for what you posted in the question.

isset returns true/false. And you are comparing boolean with 1.
