extend layout - nemesis - 11-10-2021
Hi, I'm wondering if a layout can define a default behavior that is used when the section is not defined in the view extension.
it's possible?
thanks, Paolo

Sure use an if else statement.
RE: extend layout - nemesis - 11-11-2021
I am sorry, I'll be more precisely with some examples. this is my view:
Code:
<?= $this->extend('default'); ?>
<?= $this->section('theBody') ?>
<b>This is my body, as I write in my view</b>
<?= $this->endSection() ?>Code:
<!doctype html>
<html>
<head>
<title>My Layout</title>
</head>
<body>
<?= $this->renderSection('theTitle') ?>
<?= $this->renderSection('theBody) ?>
</body>
</html>I've try to change system\View.php from
Code:
public function renderSection(string $sectionName){
if (! isset($this->sections[$sectionName])) {
return;
}
foreach ($this->sections[$sectionName] as $key => $contents) {
echo $contents;
unset($this->sections[$sectionName][$key]);
}
}to:
Code:
public function renderSection(string $sectionName){
if (! isset($this->sections[$sectionName])) {
return true;
}
foreach ($this->sections[$sectionName] as $key => $contents) {
echo $contents;
unset($this->sections[$sectionName][$key]);
}
}so that my layout become:
Code:
<!doctype html>
<html>
<head>
<title>My Layout</title>
</head>
<body>
<?php if ($this->renderSection('theTitle')): ?>
<h1>default header</h1>
<?php endif ?>
<?php if ($this->renderSection('theBody)): ?>
<p>default body</p>
<?php endif ?>
</body>
</html>this work fine but it isn't the right way! I will not change system source code... more over, it do a wrong render when I use multiple times (one inside another)...

layout.php (in App\VIew folder)
Code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
<meta name="viewport" content="width=device-width, initial-scale=1.0,shrink-to-fit=no">
<title><?=Lang('Lang.app')?></title>
<link href=...css.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div class="container">
<main role="main">
<?= view($config->views['direct_view']) ?>
<?= $this->renderSection('main') ?>
</main>
</div>
<script src=".....js"></script>some_file.php
Code:
<?= $this->extend($config->viewLayout) ?>
<?= $this->section('main') ?>
.. YOUR CONTENT HERE ...
<?= $this->endSection() ?>your_controller
Code:
public function your_function()
{
$config = config('YourConfig'); // can do this in contructor instead
return view($config->views['your_view'],[
'config' => $config,
'data' => $any_data_to_pass,
]);
}YourConfig.php (in App|config folder)
Code:
namespace App\Config;
use CodeIgniter\Config\BaseConfig;
class YourConfig extends BaseConfig
{
// you can have multiple view setting here
public $views = [
'direct_view' => 'App\Views\some_folder\direct_render_file_in_layout'
'your_view' => 'App\Views\some_folder\some_file', // link to real file with extension .php
];
public $some_parameter = 'your_value';
// Layout for the views to extend
public $viewLayout = 'App\Views\some_folder\layout';
}Routes.php
Code:
$routes->get('/', 'YourController::your_function');
I hope this can give you hint how the layout basic work and load it as single page web
You can edit file App\View\errors\html\error_404.php for custom not found page and remove default message.

thanks for the reply, but I can't understand what it has to do with my problem..
I would like to be able to define a layout that generates a complete view (with basic html for all sections), which can possibly be (partially or even totally) redefined by the view.
I await suggestions!

Do you render the View file, not the Layout in your controller?
PHP Code:
public function index()
{
echo view('some_view');
}

yes, but I think a layout could be used as a standard view as well

could you explain me in detail? I have described my implementation, but as of now I have not yet found an elegant solution - thanks!

Without the change of system\View.php, doesn't your layout work?

does not work!
since renderSection ($sectionName) does not return any value, how does the layout file know if it has been used? that is, if section($sectionName) has been called
change was in system\View\View.php:
PHP Code:
public function renderSection(string $sectionName){
if (! isset($this->sections[$sectionName]))
return false;
foreach ($this->sections[$sectionName] as $key => $contents) {
echo $contents;
unset($this->sections[$sectionName][$key]);
}
return true;
}
PHP Code:
<?php if (!$this->renderSection('aSection')): ?>
<b>default content</b>
<?php endif ?>but I think it doesn't work in case of nested use
