form action codeigniter does not find post data - php

Question

i have a problem with a form in codeigniter. i have tried different things but i can not find a solution.
this is the form:
<form method="post" action="<?php echo base_url(); ?>cms/cms/newUser">
<div class="row">
<div class="col-md-3">
Naam:
</div>
<div class="col-md-9">
<input type="text" id="naam" name="username" />
</div>
</div>
<div class="row">
<div class="col-md-3">
E-mail:
</div>
<div class="col-md-9">
<input type="email" name="mail" id="email" />
</div>
</div>
<div class="row">
<div class="col-md-3">
Passwoord:
</div>
<div class="col-md-9">
<input type="password" name="pass" id="password" />
</div>
</div>
<div class="row">
<div class="col-md-8 col-md-offset-2">
<input type="submit" name="aanmaken" class="btn btn-block btn-info" value="aanmaken" />
</div>
</div>
in my controller i process the data coming from the form.
the controller is located at controllers/cms/cms.php
class Cms extends MY_Controller
{
public function newUser()
{
if(isset($_POST))
{
echo "verwerk deze data <br>";
if(isset($_POST['username']))
{
echo 'naam is set!';
}
else {
echo 'naam is not set!';
}
$naam = $_POST['username'];
$mail = $_POST['email'];
$pass = $_POST['password'];
echo "naam: " . $naam . "<br>";
echo "mail: " . $mail . "<br>";
echo "pass: " . $pass . "<br>";
$time = new DateTime();
$time->setTimezone(new DateTimeZone ('Europe/Brussels'));
$tijd = $time->format('Y-m-d H:i:s');
include_once('application/libraries/PasswordHash.php');
$hasher = new PasswordHash(12,false);
$passwoord = $hasher->HashPassword($pass);
$gebruiker = new Gebruiker();
$gebruiker->naam = $naam;
$gebruiker->email = $mail;
$gebruiker->paswoord = $passwoord;
$gebruiker->laatsteLogin = $tijd;
$gebruiker->active = 0;
echo "coded pas" . $passwoord . "<br>";
}
else
{
echo "no post";
}
}
when i check my website and fill in the form i get 3 php error that the values that i put in the variable from the post does not exist. also the if(isset) function says that the variable is not set. i don't know why the form action doesn't work.
i even tried the codeigniter way but it gave the same result.
$name = $this->input->post('username');
thanks for the help.

HTML:
enter code here
<form method="post" action="<?php echo site_url(); ?>/cms/cms/newUser">
<div class="row">
<div class="col-md-3">
Naam:
</div>
<div class="col-md-9">
<input type="text" id="naam" name="username" />
</div>
E-mail:
<div class="row">
<div class="col-md-3">
Passwoord:
</div>
<div class="col-md-9">
<input type="password" name="pass" id="password" />
</div>
</div>
<div class="row">
<div class="col-md-8 col-md-offset-2">
<input type="submit" name="aanmaken" class="btn btn-block btn-info" value="aanmaken" />
</div>
</div>
PHP:
class Cms extends MY_Controller
{
public function newUser()
{
if(isset($_POST))
{
echo "verwerk deze data <br>";
if($this->input->post('username'))
{
echo 'naam is set!';
}
else {
echo 'naam is not set!';
}
$naam = $this->input->post('username');
$mail = $this->input->post('mail');
$pass = $this->input->post('pass');
echo "naam: " . $naam . "<br>";
echo "mail: " . $mail . "<br>";
echo "pass: " . $pass . "<br>";
$time = new DateTime();
$time->setTimezone(new DateTimeZone ('Europe/Brussels'));
$tijd = $time->format('Y-m-d H:i:s');
include_once('application/libraries/PasswordHash.php');
$hasher = new PasswordHash(12,false);
$passwoord = $hasher->HashPassword($pass);
$gebruiker = new Gebruiker();
$gebruiker->naam = $naam;
$gebruiker->email = $mail;
$gebruiker->paswoord = $passwoord;
$gebruiker->laatsteLogin = $tijd;
$gebruiker->active = 0;
echo "coded pas" . $passwoord . "<br>";
}
else
{
echo "no post";
}
}
$this->input->post('') will check automatically not need of isset().
$this->input->post('') will take name not id

Answer 2

In the form tag
<form method="post" action="<?php echo base_url(); ?>cms/cms/newUser">
cms is the name of the controller and you have used it twice. Try with
<form method="post" action="<?php echo base_url(); ?>cms/newUser">

Answer 3

you need to pass only controllername/func_name and keep your controller file in controller dir
then try in CI way
<?php echo form_open("cms/newUser");?>
<?php echo form_close();?>
or
<form method="post" action="<?php echo base_url(); ?>cms/newUser">
Else you need to use routing for this and tell to pick this controller on that route
for this go to config/routes.php and add route like:-
$route['cms'] = "cms/cms";

Answer 4

try to load form helper and use this code
controller:
$this->viewContent['form_action'] = base_url()."cms/cms/newUser";
$this->load->view('your_view_page',$this->viewContent);
view:
echo form_open($form_action);
