It's a typo. file_exits() ? It should be file_exists(). Voting to close.

Please verify the URL helper is enabled in your config function
try to use $this->uri->get_segment(1);
Try to use
$CI =& get_instance();
$this->CI->uri->segment('2')
you have to load helper in codigniter autoload.php file in config folder
$autoload['helper'] = array('url');
Try to use
codigniter autoload.php file in config folder
$autoload['helper'] = array('url');
Url : http://localhost/laravel/users/abc
$product_id = $this->uri->segment(2);
Result : abc

I am having a problem while creating a search form in CodeIgniter - it's showing errors like:

My Controller Page is:
<?php
class Login extends CI_Controller{
function search(){
$searchBook = $this->input->post('searchBook');
$data = $this->membership_model->getSearchBook($seachBook);
$this->load->view('main_content',$data);
}
?>
My Model page is:
class Membership_model extends CI_Model{
function getSearchBook($searchBook) {
$this->db->select('*');
$this->db->from('book');
$this->db->like('author',$searchBook);
return $query->result();
}
}
My main_content.php is:
<?php
echo form_open('login/search');
echo form_input('searchBook','Search Book', 'id="searchBook"');
echo form_submit('submit', 'Search');
echo form_close();
?>
<table><th>Title</th></table>
<div>
<?php
// List up all results.
foreach ($results as $val)
{
echo $val['title'];
}
?>
</div>
</body>
It's been a long time since I used CodeIgniter, but from what I remember, you're not loading the model in your Login class constructor. That's why you're getting these two parts of the error:
Message: Undefined property: Login::$membership_model
Message: Call to a member function getSearchBook() on null
Neither the property or the function exist in the Login class if you haven't loaded the membership_model model.
Off the top of my head, I think it needs to be something like this in your Login controller:
<?php
class Login extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->model('membership_model');
}
function search(){
$searchBook = $this->input->post('searchBook');
$data = $this->membership_model->getSearchBook($seachBook);
$this->load->view('main_content',$data);
}
?>
I'm following the CodeIgniter tutorial (http://www.codeigniter.com/user_guide/tutorial/news_section.html), when I get to 'Display the news' it isn't made clear where to add the second code block:
public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
the only way I can interpret the tutorial, is to add it to the News.php controller.
<?php
class News extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['news'] = $this->news_model->get_news();
}
public function view($slug = NULL)
{
$data['news_item'] = $this->news_model->get_news($slug);
if (empty($data['news_item']))
{
show_404();
}
$data['title'] = $data['news_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
}
when I add it at the end of application/controllers/News.php I get a parse error:
Parse error: parse error in /server/application/controllers/News.php on line 33
A PHP Error was encountered

if I include it within the News class, I get two PHP errors & a fatal error:

Thanks in advance.
The second code block function get_news()should go in the News_model.php file. This is how your final controller & model will look like:
Model: http://screencast.com/t/XQtJpEnSC
Controller: http://screencast.com/t/Kmec1vGh
hi i am currently working on a second module of my hmvc file and there comes an error that i think it wont load the models of this module. the previous modules models, works fine. what may be the error of this one? here is my codes.

it works perfectly fine. It just have a typo.
if($query = $this->lEmploymentStatus_Model->insert()){
$this->add_view();
lEmploymentStatus must be EmploymentStatus

I'm looking, and looking, but I dont know what is bad. The good directories are files, other classes are working but this not.
Please help. I'm just tired, because after 2 hours searching mistakes...
For CI v3, afaik
I think I see it:
$data= $this->Success_model->get_all();
Should be:
$data = $this->success_model->get_all(); // Notice the lowercase success_model
PHP variables are case-sensitive where as functions and class names are not.
One more solution would be to change
$this->load->model('success_model');
into
$this->load->model('Success_model');
because then you can use
$data= $this->Success_model->get_all();
