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
Severity: Parsing Error
Message: parse error
Filename: controllers/News.php
Line Number: 33

if I include it within the News class, I get two PHP errors & a fatal error:
Fatal error: Cannot redeclare News::index() in /server/application/controllers/News.php on line 32

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

It's a typo. file_exits() ? It should be file_exists(). Voting to close.
I am having a problem while creating a search form in CodeIgniter - it's showing errors like:

$this->db->select('*');
$this->db->from('book');

echo form_submit('submit', 'Search');

foreach ($results as $val)

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);
}
?>
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.
error

);
$insert = $this->db->insert('employment_status',$input);
return $insert;
}
}

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

As You can see this is good, but I have error:

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= $this->Success_model->get_all();
This is the most strange error I have seen in my life, because yesterday it was working and I wake up today and it's not working this is the error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Purchase::$purchase_model
Filename: controllers/purchase.php
Line Number: 67
Here is the controller code
class Purchase extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('purchase_model', 'user_model');
$this->load->helper(array('form', 'url'));
$this->load->library(array('form_validation', 'upload'));
}
function steptwo()
{
if($this->input->post('templateid') == NULL){
redirect('templates');
}
$data =$_POST;
if($this->session->userdata('userName')){
$data['name']=$this->session->userdata('userName');
}else{ $data['name'] = NULL;}
$data['paymentplans'] = $this->purchase_model->GetPplan(array('id_template_type' => $_POST['idtype']));
$this->load->view('step-two', $data);
}
An here is my model code:
class Purchase_Model extends CI_Model
{
function GetPplan($options = array())
{
// Qualification
if(isset($options['id_template_type']))
$this->db->where('id_template_type', $options['id_template_type']);
// limit / offset
if(isset($options['limit']) && isset($options['offset']))
$this->db->limit($options['limit'], $options['offset']);
else if(isset($options['limit']))
$this->db->limit($options['limit']);
// sort
if(isset($options['sortBy']) && isset($options['sortDirection']))
$this->db->order_by($options['sortBy'], $options['sortDirection']);
$query = $this->db->get("template_payment_plan");
if(isset($options['count'])) return $query->num_rows();
if(isset($options['template_payment_planid']) || isset($options['detail']))
return $query->row(0);
return $query->result();
}
}
I already have done this $autoload['libraries'] = array('database', 'session'); so I don't think this was the problem.
If anyone know what can the error be I'll be really grateful
$this->load->model('purchase_model', 'user_model');
Here you load purchase_model that you call user_model, if you want load two models, make this :
$this->load->model('purchase_model');
$this->load->model('user_model');
