console.log() is something that you would do on the client side. So what is it that you're trying to achieve when echo it from within a controller which is not on the client side of things?

Problems with a custom helper function
I'm having some problems using a function defined in a custom Helper file :s
The file is: app\Helpers\Helper.php
<?php
namespace App\Helpers;
class Helper
{
public static function logg($var)
{
echo "<script>console.log(`" . print_r($var, true) . "`);</script>";
}
}
Inside aliases array in config\app.php: 'Helper' => App\Helpers\Helper::class,
I gave composer dump-autoload php artisan config:clear and php artisan config:cache commands in the root folder of the project.
In the controller I need to use the function I have: use Helper; and when I call logg it doesn't work (Undefined function 'App\Http\Controllers\Auth\logg' so it searches for the function in the wrong place: but I have set the alias for it?). If I use use App\Helpers\Helper; and then Helper::logg() it does work (however, logg() without prefix still doesn't work), can someone help?
Laravel version: 5.5 PS: I know there is Log function in Laravel, I actually need to use other helper functions that would take too much space so I just wrote a simple function.
Here are two resources I tried before posting in the forum:
- https://stackoverflow.com/questions/28290332/best-practices-for-custom-helpers-in-laravel-5
- https://tutsforweb.com/creating-helpers-laravel/ (both the composer solution and the service provider one didn't work)

I want to display information on the status of variables and text in the JavaScript console since I can't install XDebug and Debugbar's logs can't display complex information like objects or HTTP requests...
Level 24
since <script>......</script> is work for front-end, make a component instead helper ?
Level 24
however, logg() without prefix still doesn't work
so try to create a Helper function
project-folder/app/Helpers/Helper.php
<?php
if (! function_exists('hello')) {
/**
* return "hello"
*
* @return string
*/
function hello(): string
{
return 'hello';
}
}
if (! function_exists('world')) {
/**
* return "world"
*
* @return string
*/
function world(): string
{
return 'world';
}
}
// here is no close tag ?>
project-folder/composer.json , add files the autoload
"autoload": {
"psr-4": {
"App\": "app/"
},
"classmap": [
"database/seeds",
"database/factories"
],
"files": [
"app/Helpers/Helper.php"
]
},
run composer dump-autoload
project-folder/vendor/composer/autoload_files.php , check the last line should look like this
'----------long string------' => $vendorDir . '/barryvdh/laravel-debugbar/src/helpers.php',
'----------long string------' => $baseDir . '/app/Helpers/Helper.php',
done
use it anywhere
$str = hello() . ' ' . world();
{{ hello() }}
also you can use Snippets in your editor, for example VS code
default can use log press tab

Hello, I already did all of this, but even when I call the function using the prefix, no message is shown in the console...
EDIT: I didn't actually try to use return instead of echo, I will now! Nope, it still doesn't print in the console.
Level 24
can you show the html source code from browser

Just to be sure, is your use Helper; statement below the namespace declaration?
Level 2
Yes, it's under namespace App\Http\Controllers\Auth;
I put it after others use statements
Level 9
Hmm, when I follow the steps as you've described, I don't run into issues.
Level 2
I modified my files in the following way
Helper.php is just made by the function
<?php
function logg($var)
{
return "<script>console.log(`" . print_r($var, true) . "`);</script>";
}
Then I have in my composer.json:
"autoload": {
"files": [
"app/Helpers/Helper.php"
],
But if I call the function logg nothing is printed in the console.
Level 9
Are you echo'ing the output?
Level 2
I tried both echo and return, in this version I use return because I didn't remember to set it back to echo: it doesn't log to console anyway
Level 24
because laravel {{ }} escaped the < >
try
{!! logg('test') !!}
Level 2
The logg function is called from inside a controller method (first instruction of the login() method), not from a blade page tho
Level 24
oops, in modern browser, if you return $var; it will show in json format
hmm i don't know how to do that ;(
Level 24
what about just return
if (! function_exists('logg')) {
function logg($var): string
{
return "<script>console.log(`" . print_r($var, true) . "`);</script>";
}
}
and use it in controller
return logg('test');
Level 2
This works, I just used echo in both functions because I didn't want the script to terminate ^^
