Everything works out just fine until I changed the below code from
<form method='post' action='re.php'>
to
<form method='post' action='<?php echo $_SERVER["PHP_SELF"];?>'>
It gives me HTTP error 500. I have done some googling but still have no idea why this is happening! Thanks so much for help!
Below is the whole script
<?php
$hostname = 'localhost';
$username = 'Ciara';
$password = 'mypass';
$database = 'users';
$conn = mysqli_connect($hostname,$username, $password, $database);
if (!$conn) {
die ("Databas connect failed: " . mysqli_connect_error());
} else {
echo "Connected successfully. <br>";
}
echo <<<_END
<html>
<head>
<title>Register</title>
</head>
<body><center>
<form method='post' action='<?php echo $_SERVER["PHP_SELF"];?>'>
Firstname: <input type='text' name='firstname'><br>

</form></center>
_END;
if (isset($_POST['firstname']) &&
isset($_POST['lastname']) &&
isset($_POST['email']) &&
isset($_POST['gender']) &&
isset($_POST['username']) &&
isset($_POST['password'])) {
$firstname = get($conn, 'firstname');
$lastname = get($conn, 'lastname');
$email = get($conn, 'email');
$gender = get($conn, 'gender');
$username = get($conn, 'username');
$password = get($conn, 'password');
$query = "insert into useracc values" . "(null, '$firstname','$lastname','$email','$gender','$username','$password')";
if (mysqli_query($conn, $query)) {
echo "You have successfully registered! <br>";
} else {
echo "Failed to register." . mysqli_error($conn);
}
}
mysqli_close($conn);
echo "</body></html>";
function get($conn, $var) {
return mysqli_real_escape_string($conn, $_POST[$var]);
}
?>
