Using Event file - EtZeta - 03-16-2020
I don't understand how to use an Event with a separated file with the function
for example
App/Config/Events.php
Quote:Events::on('pre_system', ['compress', 'compresstest']);
System/Events/compress.php
Quote:<?php
function compresstest()
{
console.log("Test");
}
I always have this error: ErrorException call_user_func() expects parameter 1 to be a valid callback, class 'compress' not found

You need to pass a valid callback: https://www.php.net/manual/en/language.types.callable.php
If you're going to use the array format it needs to be [$object, $method] where object is an instance or a class name. For example if you have "app/Libraries/Compress.php" you could use something like:
Events::on('pre_system', ['App\Libraries\Compress', 'compresstest']);

Thanks! I solved the problem using this
Events.php
PHP Code:
<?php namespace Config;
use CodeIgniter\Events\Events;
use App\Eventos\Compress;
$Compress = new Compress();
Events::on('pre_system', [$Compress, 'Compression']);
Compress.php
PHP Code:
<?php namespace App\Eventos;
class Compress {
public function Compression(){
echo "test";
}
}
Anyway, thank you very much!
