I am following this MVC guide to learn the basics of creating web apps with the MVC pattern.
I have set it all up and it works fine, currently the system works with urls of this form;
address.co.uk/controller/method/params
I understand how this can work, however how would this work when posting data? for example a login form, i have tried accessing the POST variables from the controller, how ever this doesn't work, im guessing this is due to the .htaccess file sends everything to the index.php?
UPDATE:
so i have created this basic form;
<form name="input" action="register/newuser" method="post">
Username: <input type="text" name="user" />
password: <input type="text" name="pass" />
<input type="submit" value="Submit" />
</form>
That submits data to this controller methods newuser;
function newuser()
{
$data['user'] = $_POST["user"];
$data['pass'] = $_POST["pass"];
$this->loadView('view_register_result',$data);
}
Then finally the result page;
<body>
<h1>Result</h1>
im not sure? <br />
user: <?php echo $data['user']; ?>
pass: <?php echo $data['pass']; ?>
</body>
Is there any reason why this doesn't work?
$_POST is a superglobal, meaning that it's available everywhere. Of course, it won't be filled unless you do an actual POST.
mod_rewrite in the .htaccess will only rewrite the URL, but it won't touch the $_POST, $_SESSION or $_COOKIE. Only the $_GET might be changed slightly, but that's beyond the scope of your question.
Edit
Your issue is definitely unrelated to the $_POST. Does passing $data as an argument to loadView add it to the template as $data, or does it add it as two separate variables: user and pass? In that case, try loadView('..', array('data' => $data))
When your form is submitted you are still calling a controller in the MVC pattern. This works the same as any page. You can use the $_POST variable in your controller to caputer that information. You can also use the $_REQUEST variable as it contains both Post and Get.
Your POST variables should always be accessible from the $_POST superglobal-array. If you fail to retrieve the values from there, it's either because the application bootstrapper is manually emptying it (i.e. to enforce usage of a dedicated library) or no POST variables were passed through with the request.
Either way, I encourage you to use an existing solution for MVC.
(Reinventing the wheel is cool for playing around and learning though.)
