CodeIgniter template engine Use instance _php instance

One, example:

It is often used in this way when using CodeIgniter:

$this->load->view (' about ', $data);

With this class library, you can load a view into this template:

$this->template->load (' template ', ' about ', $data);

This loads the view about.php into the template template file.

Second, the installation

Download Ci_template_library.zip
After decompression, the template.php is placed in the Application/libraries Application class library directory;
The application starts to load application/config/autoload.php automatically;

third, create a template file application/views/template.php
The code in the template is as follows:

$contents is what you want to insert in the controller.

Four, create a view application/views/about.php
Add the following code:

Load a view in the template engine
In your controller, you can use the

$this->template->load (' template ', ' about ');

This template engine workflow:

The view is loaded into a variable and the variable is loaded into the template

var $template _data = Array ();
 
function set ($name, $value)
{
 $this->template_data[$name] = $value;
}
 
function load ($template = ', $view = ', $view _data = Array (), $return = FALSE)
{        
 $this->ci =& get_inst Ance ();
 $this->set (' contents ', $this->ci->load->view ($view, $view _data, TRUE)); 
 return $this->ci->load->view ($template, $this->template_data, $return);

v. Skills Summary :

Advanced Tip 1: Simpler short tags in a template

Example: If you need to display the title in the page.
Then the head views/template.php in the HTML increases:

Then set it directly in the controller:

$this->template->set (' title ', ' About me ');

Advanced Tip 2: Highlight current navigation

Navigation is usually used in templates, where a good navigation should tell the user where the current location is sorted.

Define your navigation items:

Introduce application/libraries/template.php and then add to the controller:

$this->set (' nav_list ', Array (' Home ', ' Photos ', ' about ', ' contact '));

Update your Template:

Increase in application/views/template.php:

<ul class= "Navigation" >
 <?php foreach ($nav _list as $i => $nav _item):?> <li class=
 "<?= ($ Nav = = $nav _item? ' Selected ': '?> ' >
 <?= anchor ($nav _item, $nav _item)?>
 </li> <?php endforeach
 ? >
</ul>

The anchor function is used here, and you need to add the relevant small helper to the automatic load configuration:

$autoload [' helper '] = array (' URL ');

To update your controller:

Increase:

$this->template->set (' nav ', ' about ');

Need to note:
1 • If all navigation is in a single controller, you can add common navigation code to the destructor;
2 • Define the style of the current navigation, for example: #navigation. Selected

Advanced Tips 3: Multiple templates

The simplest way to handle multiple templates is to define several new methods in libraries/template.php to replace existing content, and the second advanced technique uses a custom method:

function Load_main ($view = ', $view _data = Array (), $return = FALSE)
{
 $this->set (' nav_list ', Array (' Home ', ' Photos ', ' about ', ' contact ');
 $this->load (' template ', $view, $view _data, $return);

Paste the code into the controller

$this->template->set (' nav ', ' about ');
$this->template->set (' title ', ' About Me ');
$this->template->load_main (' about ');
