Recaptcha won't post in CodeIgniter project - codeigniter

Question

I’ve a problem with implementing recaptcha in a CodeIgniter application.
The problem is that the recapctha_challenge_field and recaptcha_response_field do not get posted, however, the recapctcha (and those fields) is visible on the page (within the form).
The the recapctha_challenge_field and recaptcha_response_field are appearing in the HTML of the page, but not in the header when I post the form.
I’ve downloaded de recaptcha library and added it as an helper in CI.
Within the form in my view I echo the recaptcha_get_html($publickey) (with the public key set).
In my controller, I load the recaptchalib_helper and add set a form validation rule for the recapctha_challenge_field.
This is my view:
<h1>Register</h1>
<fieldset>
<legend>Personal information</legend>
<?php
echo form_open('login/create_user');
echo form_label('First name:', 'first_name');
echo form_input(
array(
'name' => 'first_name',
'id' => 'first_name',
'value' => set_value('first_name')
)
);
echo form_label('Last name:', 'last_name');
echo form_input(
array(
'name' => 'last_name',
'id' => 'last_name',
'value' => set_value('last_name')
)
);
echo form_label('Birth date:', 'birth_date');
echo form_input(
array(
'name' => 'birth_date',
'id' => 'birth_date',
'value' => set_value('birth_date')
)
);
echo form_label('E-mail:', 'email');
echo form_input(
array(
'name' => 'email',
'id' => 'email',
'value' => set_value('email')
)
);
?>
</fieldset>
<fieldset>
<legend>Login information</legend>
<?php
echo form_label('Username:', 'username');
echo form_input(
array(
'name' => 'username',
'id' => 'username',
'value' => set_value('username')
)
);
echo form_label('Password:', 'password1');
echo form_password(
array(
'name' => 'password1',
'id' => 'password1',
'value' => set_value('password1')
)
);
echo form_label('Confirm password:', 'password2');
echo form_password(
array(
'name' => 'password2',
'id' => 'password2',
'value' => set_value('password2')
)
);
$publickey = "mypublickey"; // here I entered my public key
echo recaptcha_get_html($publickey);
echo form_label(nbs(1), 'submit');
echo form_submit(
array(
'name' => 'submit',
'id' => 'submit',
'value' => 'Registreren'
)
);
echo form_close();
?>
<?php echo validation_errors('<p class="error">'); ?>
</fieldset>
</div>
and this is a part of my controller:
function create_user() {
print_r($_POST);//for debugging
$this->load->library('form_validation');
$this->load->model('user');
$this->form_validation->set_rules('recaptcha_challenge_field', 'Captcha', 'callback_validate_captcha');
$this->form_validation->set_rules('first_name', 'First name', 'trim|xss_clean|required');
$this->form_validation->set_rules('last_name', 'Last name', 'trim|xss_clean|required');
$this->form_validation->set_rules('email', 'E-mail', 'trim|xss_clean|valid_email|callback_is_email_available|required');
$this->form_validation->set_rules('username', 'Username', 'trim|xss_clean|min_length[5]|callback_is_username_available|required');
$this->form_validation->set_rules('password1', 'Password', 'trim|xss_clean|min_length[8]|max_length[32]|required');
$this->form_validation->set_rules('password2', 'Confirm password', 'trim|xss_clean|matches[password1]|required');
if ($this->form_validation->run() == FALSE) {
$this->signup();
} else {
if ($this->user->create_user($this->input->post('username'),$this->input->post('password1'),$this->input->post('email'),$this->input->post('first_name'),$this->input->post('last_name'),$this->input->post('birth_date'))) {
$data['main_content'] = 'login/signup_successful';
$this->load->view('includes/template', $data);
} else {
$this->load->view('login/signup_form');
}
}
}
public function validate_captcha($recaptcha_challenge_field) {
$this->load->helper('recaptchalib');
$privatekey = "myprivatekey";//this is et to my private key
$resp = recaptcha_check_answer ($privatekey,
$this->input->ip_address(),
$this->input->post("recaptcha_challenge_field"),
$this->input->post("recaptcha_response_field"));
if (!$resp->is_valid) {
$this->form_validation->set_message('validate_captcha', 'Invalid Capctha code entered.');
return FALSE;
} else {
return TRUE;
}
}
The capctha fields are not set in the HTTP headers:
Form data:
csrf_test_name:8cc3f2391784867df2d46f193a65a317
first_name:Myfirstname
last_name:Mylastname
birth_date:10-12-2012
email:myemail#adres.com
username:username
password1:password
password2:password
submit:Register
What am I doing wrong?
Your sincerely,

Answer 1

Does the form tag not begin within a table, tbody or tr?
