CodeIgniter Template engine Usage examples

This article mainly introduces the use of CodeIgniter template engine example, the need for friends can refer to the following

One, example:

This is often used when using CodeIgniter to load:

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

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

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

The view about.php is loaded into the template file.

Second, installation

Download Ci_template_library.zip
After decompression, put the template.php into the Application/libraries Application class library directory;
Application launches auto-load application/config/autoload.php;

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.

Iv. Creating a view application/views/about.php
Add the following code:




Loading views into 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 that is loaded into the template


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

v. Summary of skills :

Advanced Tip 1: Simpler short marks in templates

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




Then set directly in the controller:


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

Advanced Tip 2: Highlight current navigation

Navigation is often used in templates, and an experienced navigation should tell the user what the current location classification is.

To define your navigation items:

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


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

To update your template:

Added 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 to add the associated small helper to the auto-load configuration:


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

To update your controller:

Increase:


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

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

Advanced Tip 3: Multi-template

The simplest way to handle multiple templates is to define multiple 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 ');
