I am new to php so I used a Youtube tutorial to create this script, however the uploader seems to have disappeared so I cannot ask him any questions. My login form seems to work fine but the registration form is where I am having trouble
I have removed all html from code and all error else statements to try eliminate the error message but I cant seem to find it. Error always occurs at the end of my script.
Any suggestions
        <?php
        if ( $_POST['registerbtn'] ) {
    //makes sure email, username is valid
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getretypepass = $_POST['retypepass'];
    if (!isset($getuser))
    {
        $error = "user not set ";
    } 
    if ($getuser) {
        if($getemail) {
            if($getpass) {
                if ($getretypepass) {
        require("connection.php");
                            $query = mysql_query("SELECT * FROM          users WHERE username ='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0) {
                            $query = mysql_query("SELECT * FROM users WHERE email ='$getemail'");
