Character create problem (PHP)

[Amelith]

Can someone help me with problem? It appears when somebody want to create a character : "Your name can not contain more than 2 words." Doesn't matter what I type (even if I type one word)- its always returns that message.

Character PHP create script.

<?php require_once 'engine/init.php';
protect_page();

if (empty($_POST) === false) {
    // $_POST['']
    $required_fields = array('name', 'selected_town');
    foreach($_POST as $key=>$value) {
        if (empty($value) && in_array($key, $required_fields) === true) {
            $errors[] = 'You need to fill in all fields.';
            break 1;
        }
    }

    // check errors (= user exist, pass long enough
    if (empty($errors) === true) {
        if (!Token::isValid($_POST['token'])) {
            $errors[] = 'Token is invalid.';
        }
        $_POST['name'] = validate_name($_POST['name']);
        if ($_POST['name'] === false) {
            $errors[] = 'Your name can not contain more than 2 words.';
        } else {
            if (user_character_exist($_POST['name']) === true) {
                $errors[] = 'Sorry, that character name already exist.';
            }
            if (!preg_match("/^[a-zA-Z_ ]+$/", $_POST['name'])) {
