Question

On my website , i want to register a user.

My HTML is:

<form method="post" action="register.php">
            <h1>Register</h1>
            <p>If you already have an account, please login</p>
            <div class="styled_select">
                <select name="title">
                    <option value="mr">Mr</option>
                    <option value="mrs">Mrs</option>
                    <option value="miss">Miss</option>
                </select>
            </div>

            <input type="text" name="first_name" placeholder="First Name" required><br>
            <input type="text" name="last_name" placeholder="Last Name" required><br>
            <div class="styled_select">
                <select name="sex" required>
                    <option value="male">Male</option>
                    <option value="female">Female</option>
                </select>
            </div>
            <input type="text" name="age" placeholder="Age" required><br>
            <input type="text" name="email" placeholder="Email" required><br>
            <input type="text" name="zipcode" placeholder="Zipcode" required><br>
            <input type="text" name="telephone" placeholder="Telephone" required><br>
            <input type="checkbox" class="checkbox" required> Agree to terms and conditions. <br>
            <input type="checkbox" class="checkbox" name="keep_informed"> Keep me informed on future promotions. <br>
            <input type="submit" name="" value="Register" class="submit_button"><br>
        </form>

My php function is:

class Register {

    public function register($title, $first_name, $last_name, $sex, $age, $email, $zipcode, $telephone, $keep_informed) {

        $title = mysql_real_escape_string($title);
        $first_name = mysql_real_escape_string($first_name);
        $last_name = mysql_real_escape_string($sex);
        $sex = mysql_real_escape_string($age);
        $email = mysql_real_escape_string($email);
        $zipcode = mysql_real_escape_string($zipcode);
        $telephone = mysql_real_escape_string($telephone);
        $keep_informed = mysql_real_escape_string($keep_informed);  

        $dbh = new PDO('mysql:host=localhost;dbname=testbox_new', 'root', '');

        $sql = 'insert into users (title, first_name, last_name, sex, age, email, zipcode, telephone, keep_informed)
        values ("'.$title.'", "'.$first_name.'", 
        "'.$last_name.'", "'.$sex.'", 
        "'.$age.'", "'.$email.'", 
        "'.$zipcode.'", "'.$telephone.'", 
        "'.$keep_informed.'")';

        if ($dbh->exec($sql)) {
            return true;
        } else {
            return false;
        }
    }
}

and i call the function with:

if (isset($_POST['title']) && isset($_POST['first_name']) 
                            && isset($_POST['last_name']) 
                            && isset($_POST['sex']) 
                            && isset($_POST['age']) 
                            && isset($_POST['email']) 
                            && isset($_POST['zipcode']) 
                            && isset($_POST['telephone'])) {

    if (isset($_POST['keep_informed'])) {
        $keep_informed = $_POST['keep_informed'];
    } else {
        $keep_informed = 0;
    }
    $register = new Register;
    $insert = $register->register($_POST['title'], $_POST['first_name'], $_POST['last_name'], $_POST['sex'], $_POST['age'], $_POST['email'], $_POST['zipcode'], $_POST['telephone'], $keep_informed);
    if ($insert == true) {
        header ('location: index1.php');
    } else {
        echo 'somethings gone wrong';
    }

}

The errors i get are the following:

Is there anyone who knows what the problem is ? I really can't figure it out!

Any help would be appreciated ;)

Thx!

Answer 1

This is the line that's causing the issue:

$register = new Register;

Your Register class doesn't have an explicit constructor. When you instantiate the object, PHP is checking to see if there's an old-style constructor in there - that is, a method that has the same name as the class. And it does - your register() method is being called then.

To get around this, you can either add in a constructor method to your class, or re-name the register method.

You can see the details of how constructors work in the manual: http://php.net/manual/en/language.oop5.decon.php
