codeigniter form not submitting data - php

Question

I have tried everything I can think of but whenever I click submit the form passes on a null value, I dont know if it is the problem with the form or the controller or even the view. I changed this->input->post to posted data and i get an error of undefined variable posted data, please help.
Controller:
public function addmenu(){
$this->load->model('organizer_model');
$data = array(
'menu_name' => $this->input->post('menu name'),
'price' => $this->input->post('price'),
'email' => $this->session->userdata('email')
);
if($this->organizer_model->insertmenu($data)) {
$this->session->set_flashdata('message', 'Your menu has been added');
redirect('/menu/index', 'refresh');
} else {
$this->session->set_flashdata('message', 'Your menu was not added, please try again');
redirect('/menu/index', 'refresh');
}
View:
<form action="<?php echo site_url('Organizer/addmenu'); ?>" method="post" class="form-horizontal no-margin">
<div class="control-group">
<label class="control-label" for="menuname">
Menu Name
</label>
<div class="controls controls-row">
<input class="span3" name="data[menuname]" type="text" placeholder="Enter menu Name">
</div>
</div>
<div class="control-group">
<label class="control-label" for="price">
Price
</label>
<div class="controls controls-row">
<input class="span3" name="data[price]" type="text" placeholder="">
</div>
</div>
<div class="form-actions no-margin">
<button type="submit" name="submit" class="btn btn-info pull-right">
Add menu
</button>
<div class="clearfix">
</div>
</div>
</form>
Model:
public function insertmenu($data) {
$condition = "email = '" . $data['email'] . "'";
$this->db->select('organizer_id');
$this->db->from('organizer');
$this->db->where($condition);
$this->db->limit(1);
$query = $this->db->get();
if ($query->num_rows() > 0){
array_pop($data); //will remove email from data
$row = $query->row();
$data['organizer_id'] = $row->organizer_id;
$this->db->insert('menu', $data);
if ($this->db->affected_rows() > 0) {
return true;
} else {
return false;
}
} else {
return false;
}
}

I notice same question here codeigniter- insert data into db not working
Checks
Make sure you load your form helper and url helper.
Make sure you use form validation when submitting form in codeigniter on controller.
From this php user guide here http://php.net/manual/en/reserved.variables.post.php
Example on your input would be like person[0][first_name]
<form action="" method="">
<input type="text" name="data_posts[0][menu_name]" placeholder="Enter menu Name">
<input type="text" name="data_posts[0][price]" placeholder="">
</form>
Model
<?php
class Model_something extends CI_Model {
public function add_menu() {
$data_posts = $this->input->post('data_posts');
foreach ($data_posts as $data_post) {
$data = array(
'email' => $this->session->userdata('email'),
'menu_name' => $data_post['menu_name'],
'price' => $data_post['price']
);
$this->db->insert('tablename', $data);
}
}
}
Controller
<?php
class Add_menu extends CI_Controller {
public function index() {
$this->load->helper('form');
$this->load->helper('url');
$this->load->library('form_validation');
$data_posts = $this->input->post('data_posts');
foreach ($data_posts as $data_post) {
$this->form_validation->set_rules('data_posts['.$data_post.'][menu_name]', 'Menu Name', 'required');
$this->form_validation->set_rules('data_posts['.$data_post.'][price]', 'Price', 'required');
}
if ($this->form_validation->run() == FALSE) {
$this->load->view('some_view');
} else {
$this->load->model('model_something');
$this->model_something->add_menu();
redirect('to_success_page');
}
}
}
You could also check if has been inserted by using callback function

Also you should upgrade to the new bootstrap I see your using old version.
