  • 0

I have created a php person class and a very basic form. The form is to output the data to another page. This is a scaled down version it does not have all of the coding included but I think I have the jist of it. I cannot figure out why it is not working. It cant be anything big nor do I think I am missing any steps. Note my code below:

I’m not getting any errors at all… That data being keyed into the form is not rendering to my proceslogin.php page.

This is my form.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Login</title>
</head>
                <div>
                    <form id="login" method="post" action="proceslogin.php">
                    <label for="firstname"> First Name: </label>
                    <input type="text" id="firstname" name="firstname" maxlength="100" tabindex="1" />

                    <label for="lastname"> Last Name: </label>
                    <input type="text" id="lastname" name="lastname" maxlength="100" tabindex="2" />

                    <input type="submit" id="submit" name="submit" value="Retrieve Full Name"/>

                    </form>

                </div>

<body>
</body>
</html>

This is my class

<?php
//Person Class
class Person{
    //attributes for the first and last name of the class
    private $firstname;
    private $lastname;

    /*Constructs the function*/
    public function __construct(){
    }

    /*Destroys the function*/
    public function __destruct(){
    }

    /*Get function*/
    public function __get($name) {
        return $this->$name;
    }

    /*Use the set function*/
    public function __set($name, $value) {
        $this->$name=$value;
    }

    /*Whis is what retrieves the values from memmory*/
    public function retrieve_full_name() {
        $fullname = $this->firstname . ' ' . $this->lastname;
        return $fullname;
    }
} //End of class
?>

This is the page the class object is to render in.

    <?php

        require_once('websiteconfig.inc.php');

    ?>

    You are using $lastname and $firstname when pulling from the _POST variable, which it should just be the name. You also had firstname set where lastname should be.

    So this is how your php code should look.

    PS: look into Smarty, it will help clean this all up.

    <?php
        require_once('websiteconfig.inc.php');
?>
