    /* Check if Login is set */
    if(isset($_POST['register'])) {

    /* Check Username */
    if(!empty($_POST['username'])) {

    $check_username = strtolower($_POST['username']);

    /* Check the username length */
    $length = strlen($check_username);
    if($length >= 5 && $length <= 25) {

    /* Is the username Alphanumeric? */
    if(preg_match('/[^a-zA-Z0-9_]/', $check_username)) {
    $error[] = "Please enter a valid alphanumeric username";
    $username = null;
    } else {
    $database->query('SELECT id FROM users WHERE username = :username', array(':username' => $check_username));

    /* Check if user exist in database */
    if($database->count() == 0) {

    /* Require use to validate account */
    if($this->email_verification == true) {

    /* Check if user exist in inactive database */
    $database->query('SELECT date FROM users_inactive WHERE username = :username', array(':username' => $check_username));

    /* If user incative is older than 24 hours */

    $user = $database->statement->fetch(PDO::FETCH_OBJ);
    if($database->count() == 0 or time() >= strtotime($user->date) + 86400) {

    /* If user incative is older than 24 hours */
    $username = $_POST['username'];
    } else {

    /* Check Password */
    if(!empty($_POST['password'])) {

    /* Do passwords match? */

    if(isset($_POST['password_again']) && $_POST['password_again'] == $_POST['password']) {

    /* Is the password long enough? */
    $length = strlen($_POST['password']);
    if($length >= 8) {
    $password = $_POST['password'];
    } else {
    $error[] = "Passwords must be atleast than 8 characters";

Regarding your “gender” value problem – You need to change this code

<select name="gender" value="' . $gender . '">
    <option value="">Choose</option>
    <option value="Male">Male</option>
    <option value="Female">Female</option>

To

<select name="gender">
    <option value="" ' .($gender == '' ? 'selected="selected"' : '') . '>Choose</option>
    <option value="Male" ' .($gender == 'male' ? 'selected="selected"' : '') . '>Male</option>
    <option value="Female" ' .($gender == 'female' ? 'selected="selected"' : '') . '>Female</option>

You are trying to set a value to select tag which is invalid.
