RE: Where place render page code? - cb32 - 11-17-2022
That should probably be in your controller. Then after loading what you need you determine what is the right view to load.

First of all, you should read CI manual / documentation and from that understand what you can do / make hand-in-hand with what you need to achieve.
This forum is not meant for teaching you understand programming and developing, or do a work for you, but for solving issues and helping each other.

Long story short:
Extend controller to some kind of base controller, where base controller always collects all "routine" stuff. Use view layouts with extending and creating sections.
This is how i use CI benefits. This is jsut a basic and totally simple example.
App/Controllers/BaseController.php
PHP Code:
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
class BaseController extends Controller
{
public object $data;
public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
{
parent::initController($request, $response, $logger);
$this->initData();
}
protected function initData()
{
// collect all "routine" code, data, etc...
$this->data = (object) [
'layout' => (object) [
'header_title' => '',
]
'menu' => [
0 => [
'title' => 'Contact Us',
'url' => '/contact-us',
],
1 => [
'title' => 'About us',
'url' => '/abour-us',
],
],
'misc' => [],
];
}
public function render(string $name): string
{
return view($name, (array) $this->data);
}
}
App/Controllers/MainController.php
PHP Code:
<?php
namespace App\Controllers;
use App\Controllers\BaseController;
class MainController extends BaseController
{
public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
{
parent::initController($request, $response, $logger);
}
public function index(): string
{
$this->data->layout->header_title = 'Homepage';
return $this->render(__FUNCTION__);
}
}
App/Views/layout.php
PHP Code:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<?=$this->include('/views/layout_header');?>
<body>
<?=$this->renderSection('content');?>
</body>
<?=$this->include('/views/layout_footer');?>
</html>
App/Views/layout_header.php
PHP Code:
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
<title><?=$layout->header_title;?></title>
</head>
App/Views/layout_footer.php
PHP Code:
<footer>
<?php foreach ($menu as $link) { ?>
<a href="<?=$link['url'];?>">
<?=$link['title'];?>
</a>
<?php } ?>
</footer>
App/Views/index.php
PHP Code:
<?=$this->extend('App\Views\layout');?>
<?=$this->section('content');?>
<h1>Hello, World!</h1>
<p>This is <?=$layout->header_title;?></p>
<?=$this->endSection();?>RE: Where place render page code? - Sprint - 11-17-2022
What is the most convenient method
for example, in the controller
Code:
<code>function action_index(){
$my_var = "test";
$this->template->my_var = $my_var;
$this->template->render();
}
</code>
or in the model
<code>class Model_my_model extends Model{
function my_model(){
$my_var = "test";
$this->template->my_var = $my_var;
$this->template->render();
}
}
</code>A:
You could create a base controller with the common code and extend it in the other controllers.
Code:
<code>class Controller_Base extends Controller
{
public function before()
{
parent::before();
// do common stuff here
$my_var = "test";
$this->template->my_var = $my_var;
}
}
