I am new to CI and wanted to get some feed back on my code and just get a feel of where my thought process is and if I am really getting my head wrapped around CI.
I have a file in my core directory called My_Controller which has this code:
<?php
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->data = array(
'title' => '',
'keywords' => 'default keywords',
'description' => 'default description',
'layout' => 'default',
'view' => '',
'body_class' => '',
'data' => array()
);
}
}
I also have a controller called home in the controller directory with this code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Home extends MY_Controller
{
function __construct()
{
parent::__construct();
}
public function index()
{
/*
Set variables to send to the wrapper template
Default values are stored in /application/core/MY_Controller.php
*/
$this->data['title'] = 'Home';
$this->data['keywords'] = 'Home';
$this->data['description'] = 'Home';
$this->data['view'] = 'content/home';
$this->data['body_class'] = 'home';
$this->data['data'] = array(); // associative array of values you can pass to the view
$this->load->view('layout/default', $this->data);
}
}
**And finally I have a view named default which hold my header and footer info. Now I would like to dynamically load the correct content view depending on where I am in my site. This is what I have for my default view:
<!doctype html>

<!--[if IE 8]> <html class="no-js ie8 oldie" lang="en"> <![endif]-->

I get the correct syntax from home.php but I also get these errors:
** A PHP Error was encountered
Severity: Warning Message: ob_start(): output handler 'ob_gzhandler' conflicts with 'zlib output compression' Filename: core/Output.php Line Number: 379**
** A PHP Error was encountered
Severity: Notice Message: ob_start(): failed to create buffer Filename: core/Output.php Line Number: 379**
Can someone please tell me if I'm missing something or if this is just plain incorrect.
My guess is that you have Output Compression enabled and you are prematurely echoing something to the browser. Head into config/config.phpand disable output compression:
/*
|--------------------------------------------------------------------------
| Output Compression
|--------------------------------------------------------------------------
|
| Enables Gzip output compression for faster page loads. When enabled,
| the output class will test whether your server supports Gzip.
| Even if it does, however, not all browsers support compression
| so enable only if you are reasonably sure your visitors can handle it.
|
| VERY IMPORTANT: If you are getting a blank page when compression is enabled it
| means you are prematurely outputting something to your browser. It could
| even be a line of whitespace at the end of one of your scripts. For
| compression to work, nothing can be sent before the output buffer is called
| by the output class. Do not 'echo' any values with compression enabled.

$config['compress_output'] = FALSE;
