Hi,
I've wrote a little library (hook) to auto load a template file + view without writing $this->load->view('index'); in every method of your controller.
/application/config/template.php
1) AUTOLOAD this config in /application/config/autoload.php
Code:
<?php
/*
|--------------------------------------------------------------------------
| Default Template
|--------------------------------------------------------------------------
|
| This determines which set of view files should be used. Make sure
| there is an available template if you intend to use something other
| than the default template.
|
*/
$config['template'] = "default";
/application/libraries/Template.php
Code:
<?php
class Template {
var $CI;
function __construct() {
$this->CI =& get_instance();
}
function set() {
if (!isset($this->CI->_template)) {
$this->CI->_template = $this->CI->config->item('template');
}
if (!isset($this->CI->_view)) {
$this->CI->_view = $this->CI->router->class.'/'.$this->CI->router->method;
}
if ($this->CI->_template) {
$this->CI->data['_view'] = $this->CI->_template.'/'.$this->CI->_view;
$this->CI->load->view($this->CI->_template.'/template', $this->CI->data);
} elseif ($this->CI->_view) {
$this->CI->load->view($this->CI->_view, $this->CI->data);
}
}
}
/application/config/hooks.php
1) ENABLE hooks in /application/config/config.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/*
| -------------------------------------------------------------------------
| Hooks
| -------------------------------------------------------------------------
| This file lets you define "hooks" to extend CI without hacking the core
| files. Please see the user guide for info:
|
| http://ellislab.com/codeigniter/user-guide/general/hooks.html
|
*/
$hook['post_controller'][] = array(
'class' => 'Template',
'function' => 'set',
'filename' => 'Template.php',
'filepath' => 'libraries',
'params' => array()
);
/* End of file hooks.php */
/* Location: ./system/application/config/hooks.php */
Data for views should put in:
Code:
$this->data['persons'] = $persons;
Put this line in your template file:
1) See below for the folder structure
Code:
<? $this->load->view($_view) ?>
Example template.php
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html >
<head>
<title>Template</title>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
<link rel="stylesheet" type="text/css" href="/assets/stylesheets/default.css" media="all" />
</head>
<body>
<? $this->load->view($_view) ?>
</body>
</html>
Your folder structure for the views in default setup:
/application/views/default/ <- template folder
/application/views/default/template.php <- the template
/application/views/default/home/ <- the controller folder containing the controller views by method
/application/views/default/home/index.php <- the method view
URLS:
/ -> loads /default/home/index.php <- depending on your routes
/home -> loads /default/home/index.php
/home/start -> loads /default/home/start.php
You do not need to use $this->load->view() anymore. When you want to switch from template you can use this in your controller:
Code:
$this->_template = 'mobile';
/* no template at all */
$this->_template = FALSE;
/* if you want to set a different view then the method or controller */
$this->_view = 'class/method'; /* loads /default/class/method.php */
/* or */
$this->_view = 'person/edit'; /* loads /default/person/edit.php */
/* no view */
$this->_view = FALSE;
/* no template and view (blank page) */
$this->_template = $this->_view = FALSE;
Now my contact controller looks like this:
Code:
class Contact extends Controller {
function __construct() {
parent::Controller();
$this->load->model('contact_model');
}
function index() {
$this->data['contacts'] = $this->contact_model->get();
}
function add() {
$this->_view = 'contact/edit';
}
function edit($id = NULL) {
if ($id) {
$this->data['contact'] = $this->contact_model->get_by_id($id);
} else {
redirect('contact/add');
}
}
}
index() loads /default/contact/index.php
add() loads /default/contact/edit.php
edit() loads /default/contact/edit.php
If you found anything missing please contact me and I'll update this post. I'm still sleepdrunk
