passing variable - shows invalid variable ...

this should have been easy.... but for some reason its not working ...
Controller..

Code:

<?php

namespace App\Controllers;

use App\Controllers\BaseController;
use App\Models\UserModel;

class Login extends BaseController
{
    public function index()
    {
        return view('login');
    }
 
    public function authenticate()
    {
        $session = session();
        $userModel = new UserModel();

        $email = $this->request->getVar('email');
        $password = $this->request->getVar('password');
       
        $user = $userModel->where('user_email', $email)->first();
       
        if(is_null($user)) {
            return redirect()->back()->withInput()->with('error', 'Invalid username or password.');
        }

        $pwd_verify = password_verify($password, $user['user_pass']);

        if(!$pwd_verify) {
            return redirect()->back()->withInput()->with('error', 'Invalid username or password.');
        }

        $ses_data = [
            'user_id' => $user['user_id'],
            'user_email' => $user['user_email'],
            'isLoggedIn' => TRUE
        ];

        $session->set($ses_data);
        $data = array("js_to_load"=> "hello");
     
       
        //$data['js_to_load']=array("https://cdn.datatables.net/2.2.2/js/dataTables.js","https://cdn.datatables.net/2.2.2/js/dataTables.tailwindcss.js");

        return view( '/dashboard', $data);
 
       
       
    }
}

View - dashboard

Code:

<?=$this->extend("layouts/postlogin_layout")?>
 
<?=$this->section("content")?>

        <?php echo $js_to_load; ?>
       
 

    <?=$this->include('partials/usersettings');?>
   
<?=$this->endSection()?>

keep getting

ErrorException - Undefined variable $js_to_load

I have tried everything ..

Code:

$this->load->view('/dashboard',$data);
return view( '/dashboard', $data);
echo view('dashboard', $data);

all give the same invalid variable
if in the view i put

Code:

print_r($_SESSION);

it print's the session...
I know i am making a very small mistake some where just dont know where ...

Are you really getting to the place where the template is output? redirect() does not interrupt execution?
If so, do you need to set the default value: echo $js_to_load ?? 'Hello';

This is bizarre because I think the code looks fine. My best guess is that your dashboard view is getting returned somewhere else where $js_to_load isn't passed to it. Could it be something to do with the redirects, or perhaps another controller method is returning the dashboard view. That's where I'd start to look.

Alternatively you have unearthed a CI bug, but I think this seems unlikely. I might try renaming the variable to minimise this as a possibility.

Can you try print_r() in your controller?

PHP Code:

echo "<pre>";
print_r(your_js_message_data);
die(); 


What version of CodeIgniter 4 are you running?

Another thing you can try is this:

PHP Code:

// Views/data.php

<?php


// Controller

public function index()
{
    $data = [
        'js_to_load' => 'Testing'
    ];

    return view('data', $data)
        . view('your_view');
} 


Did you try passing it like this?

PHP Code:

$data["js_to_load"] = "hello";

Also I found that in the views with CodeIgniter 4.6.0 and PHP 8.4.5 I have to add the following in my views

PHP Code:

<?php
/**
 * Main View (menu_editor/index.php)
 * ----------------------------------------------
 *
 * @var TYPE_NAME $title
 * @var TYPE_NAME $menus
 */

$this->extend('layouts/main');
?>
