Conditional layout templates - legon614 - 08-20-2020
I want to use layout templates instead of doing this:
PHP Code:
echo view('html_top', $vars);
echo view($view, $vars);
echo view('html_bottom', $vars);
The think is - my application handles views differently if they are AJAX calls or not. If they are AJAX it returns a JSON with the view inside of it. If not, it will return the view with top html and bottom html. For this to work I have created a View library, like so:
PHP Code:
public function view($view, $vars = array())
{
$request = service('request');
$siteConfig = config('Site');
$session = service('session');
$page_title = $this->url_to_title($vars);
if ($request->isAJAX()) {
if (isset($vars['json'])) {
$data['manipulateDom'] = $vars['json'];
}
$data['title'] = $page_title;
$vars['logged_in'] = $session->logged_in;
$vars['site_name'] = $siteConfig->name;
$data['content'] = view($view, $vars);
echo json_encode($data);
} else {
$vars['page_title'] = $page_title;
$vars['logged_in'] = $session->logged_in;
$vars['site_name'] = $siteConfig->name;
echo view('html_top', $vars);
echo view($view, $vars);
echo view('html_bottom', $vars);
}
}
But view templates are not triggered from the controller, but from the view. Is there any way of echoing a template in a controller with another view inside of it? I guess I can pass $request->isAJAX() to the view and do something like this:
PHP Code:
<?php if ($isAJAX): ?>
<?= $this->extend('default') ?>
<?php endif; ?>But it doesn't feel right, and I would then have to put it in all views. I rather do it from the controller or a lib.

Your template can use include() to render the main content, and for your ajax call you can return only this view. See https://codeigniter4.github.io/userguide/outgoing/view_layouts.html#including-view-partials
PHP Code:
<?= $this->extend('default') ?>
<?= $this->section('content') ?>
<?= $this->include('main_content') ?>
<?= $this->endSection() ?>RE: Conditional layout templates - InsiteFX - 08-21-2020
You can also echo a view in a view.
