Migrating code from joomla 3 to joomla 4 Topic is solved

[Gibernet]

I'm migrating a code from joomla 3 to joomla 4.

I used this php code to detect if the client is using a mobile device or not:

$appWeb = new JApplicationWeb;

if ($appWeb->client->mobile) {
echo "<BR>IS mobile<BR>";
}
else {
echo "<br>is NOT mobile<br>";
}

I have seen that the JApplicationWeb has changed, but I haven't found the new version of it.

Does anyone know how to make this call in joomla 4?

Thanks in advance.

Joomla 4 has a file /libraries/classmap.php with all old JClasses and the new names.
See https://github.com/joomla/joomla-cms/bl ... assmap.php

In Joomla 4 you can use:

Code: Select all

<?php 

use Joomla\CMS\Application\WebApplication;

$appWeb = new ApplicationWeb;

You don't need to create a whole new application instance just to read client information. You can use Joomla\Application\Web\WebClient class directly. But in CMS context you can get it through current application instance:

Code: Select all

Joomla\CMS\Factory::getApplication()->client->mobile

There is also Joomla\CMS\Environment\Browser class:

Code: Select all

Joomla\CMS\Environment\Browser::getInstance()->isMobile()

Not sure which one is more reliable in terms of detection.

Thanks for that Joomla\CMS\Environment\Browser::getInstance()->isMobile() tip!
