CI4 beta.1 - How to load view in view with layout - pinebranch - 03-08-2019

Hello,

In beta 1, how can I load a partial view in a view with layout?

When I use this code, nothing is rendered.

PHP Code:
<?= $this->extend('layout') ?>

<?= $this->section('content') ?>
    <?= view('partial'); ?>
    <h1>Hello World!</h1>
<?= $this->endSection() ?>

But without layout, it will work.

PHP Code:
<?= view('partial'); ?>
<h1>Hello World!</h1>

His error report seems to be similar to that found by me:

I solved this by extending the core View class, added a function to render partial view.

Function renderPartial is combined from function render and renderString of the View class. I also put additional data for partial view in $options parameter.

PHP Code:
<?php namespace App\Core;

use CodeIgniter\View\View;

class MyView extends View {

    public function renderPartial(string $view, array $options = null, $saveData = null): string
    {
        $start = microtime(true);
        if (is_null($saveData))
        {
            $saveData = $this->config->saveData;
        }

        $fileExt                     = pathinfo($view, PATHINFO_EXTENSION);
        $realPath                    = empty($fileExt) ? $view . '.php' : $view; // allow Views as .html, .tpl, etc (from CI3)
        $this->renderVars['view']    = $realPath;
        $this->renderVars['options'] = $options;

        // Was it cached?
        if (isset($this->renderVars['options']['cache']))
        {
            $this->renderVars['cacheName'] = $this->renderVars['options']['cache_name'] ?? str_replace('.php', '', $this->renderVars['view']);

            if ($output = cache($this->renderVars['cacheName']))
            {
                $this->logPerformance($this->renderVars['start'], microtime(true), $this->renderVars['view']);
                return $output;
            }
        }

        $this->renderVars['file'] = $this->viewPath . $this->renderVars['view'];

        if (! is_file($this->renderVars['file']))
        {
            $this->renderVars['file'] = $this->loader->locateFile($this->renderVars['view'], 'Views', empty($fileExt) ? 'php' : $fileExt);
        }

        if (! is_null($options)) {
            $this->setData($options);
        }
            
        extract($this->data);

        if (! $saveData)
        {
            $this->data = [];
        }

        ob_start();
        include($this->renderVars['file']);
        $output = ob_get_contents();
        @ob_end_clean();

        $this->logPerformance($start, microtime(true), $this->excerpt($view));

        return $output;
    }

} 

In app\Config\Services.php, add a function to override renderer service using MyView

PHP Code:
public static function renderer($viewPath = null, $config = null, bool $getShared = false)
    {
        if ($getShared)
        {
            return static::getSharedInstance('renderer', $viewPath, $config);
        }

        if (is_null($config))
        {
            $config = new \Config\View();
        }

        if (is_null($viewPath))
        {
            $paths = config('Paths');

            $viewPath = $paths->viewDirectory;
        }

        return new \App\Core\MyView($config, $viewPath, static::locator(true), CI_DEBUG, static::logger(true));
    } 

Then in a view with layout, you can call a partial view like this

PHP Code:
<?= $this->extend('layout') ?>

<?= $this->section('content') ?>
    <?= $this->renderPartial('partial'); ?>
    <h1>Hello World!</h1>
<?= $this->endSection() ?>

You should never ever edit or add to a CodeIgniter system class file!

You need to extend the class in question.

A new method, include() has been added to the View system that can be used just like renderPartial above.

Hello, i'm having issues with this method it reads the file but encounters a problem

Code:
CRITICAL - 2020-03-25 23:45:57 --> Invalid file: ci4_footer.php

#0 C:\AppServ\www\ferv\PTP\vendor\codeigniter4\framework\system\View\View.php(224): CodeIgniter\Exceptions\FrameworkException::forInvalidFile('ci4_footer.php')

#1 C:\AppServ\www\ferv\PTP\vendor\codeigniter4\framework\system\View\View.php(503): CodeIgniter\View\View->render('ci4_footer', NULL, true)

#2 C:\AppServ\www\ferv\PTP\app\Views\CR\Ini\inicioSesion\inicioSesion.php(43): CodeIgniter\View\View->include('ci4_footer')

#3 C:\AppServ\www\ferv\PTP\vendor\codeigniter4\framework\system\View\View.php(236): include('C:\\AppServ\\www\\...')

#4 C:\AppServ\www\ferv\PTP\vendor\codeigniter4\framework\system\Common.php(1071): CodeIgniter\View\View->render('cr/ini/inicioSe...', Array, true)

#5 C:\AppServ\www\ferv\PTP\app\Controllers\Ini.php(9): view('cr/ini/inicioSe...')

#6 C:\AppServ\www\ferv\PTP\vendor\codeigniter4\framework\system\CodeIgniter.php(910): App\Controllers\Ini->inicioSesion()

#9 C:\AppServ\www\ferv\PTP\public\index.php(45): CodeIgniter\CodeIgniter->run()

#10 {main}

and the file "ci4_footer.php" contains

Code:
    <div class="environment">

            <p>Page rendered in {elapsed_time} seconds</p>

            <p>Environment: <?= ENVIRONMENT ?></p>

    </div>

in the view

Code:
<footer>

    <?php $this->include('ci4_footer'); ?>

</footer>

it's pretty simple, but i don't know where i'm making the error, any recommendation?

best regards

When I use this method like this:

PHP Code:
<?php $data["name"] = ""; ?>
<?= $this->include("includes/modal",$data); ?>

In Views/includes/modal.php I do:

PHP Code:
<?php echo $name;?>

Then I get an error:

ErrorException

Undefined variable: name

How do we put variables for just the php partial page I am including, I dont want to define the partial page variables in the controller, I need to define them in the template as its building out the page html in the view

RE: CI4 beta.1 - How to load view in view with layout - InsiteFX - 03-12-2021

Then create a Library and then use the View Cell Method.
