hi, i'm trying to learn codeigniter (following a book) but don't understand why the web page comes out empty.
my controller is
class Welcome extends Controller {
function Welcome()
{
parent::Controller();
}
function index()
{
$data['title'] = "Welcome to Claudia's Kids";
$data['navlist'] = $this->MCats->getCategoriesNav();
$data['mainf'] = $this->MProducts->getMainFeature();
$skip = $data['mainf']['id'];
$data['sidef'] = $this->MProducts->getRandomProducts(3, $skip);
$data['main'] = "home";
$this->load->vars($data);
$this->load->view('template');
}
the view is:
<--doctype declaration etc etc.. -->
</head>
<body>
<div id="wrapper">
<div id="header">
<?php $this->load->view('header');?>
</div>
<div id='nav'>
<?php $this->load->view('navigation');?>
</div>
<div id="main">
<?php $this->load->view($main);?>
</div>
<div id="footer">
<?php $this->load->view('footer');?>
</div>
</div>
</body>
</html>
Now I know the model is passing back the right variables, but the page appears completely blank. I would expect at least to see an error, or the basic html structure, but the page is just empty. Moreover, the controller doesn't work even if I modify it as follows:
function index()
{
echo "hello.";
}
What am I doing wrong? Everything was working until I made some changes to the model - but even if I delete all those new changes, the page is still blank.. i'm really confused!
thanks, P.
I've isolated the function that gives me problems. here it is:
function getMainFeature()
{
$data = array();
$this->db->select("id, name, shortdesc, image");
$this->db->where("featured", "true");
$this->db->where("status", "active");
$this->db->orderby("rand()");
$this->db->limit(1);
$Q = $this->db->get("products");
if ($Q->num_rows() > 0)
{
foreach($Q->result_arry() as $row)
{
$data = array(
"id" => $row['id'],
"name" => $row['name'],
"shortdesc" => $row['shortdesc'],
"image" => $row['image']
);
}
}
$Q->free_result();
return $data;
}
I'm quite convinced there must be a syntax error somewhere - but still don't understand why it doesn't show any error, even if I've set up error_reporting E_ALL in the index function..
