Hello,

I am playing around with CI4, I have a very simple page that doesn't have any JS on it.

But if change the environment to development I start getting these errors:

[Image: Screenshot-2020-11-26-at-23-42-15.png]


I tried removing the catch and emptying the writable folder. 

It's so annoying, page is only 5 lines of HTML code and no JS, where is the problem?

hello there,

im just learning codeigniter 4 from youtube "web programming unpas". so im followed his course to create form with post method to insert data.
after insert the data succesfully, it will redirect to the index file. then, after i tried to insert data, the data its inserted successfully, but cannot redirect and showing error

"localhost send an invalid response"

here the code
route.php
Code:
$routes->get('/', 'pages::index');

$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/(:segment)', 'komik::detail/$1');

controller/komik.php
Code:
<?php
namespace App\Controllers;

use App\Models\komikmodel;

class komik extends BaseController

    {
         protected $komikmodel;
   
         public function __construct()

submit on a form

November 27, 2020, 6:02 am
$

I have an email that I am sending to users. In it a user clicks on a link which brings them to http://localhost/index.php/Configure/MyFormEmployee which is a function in my controller that displays a survey.  They fill out the form and hit "submit" which brings them to http://localhost/index.php/Configure/survey_results which is another function in my controller. In survey_results() I will total up the survey and write the results to a mysql table. Ignore the "localhost" implications since that is just for testing. 

But what happens if the user of the CI application is no longer running the application? Since this survey invitation is sent via email and the receiver has 48 hours to fill out a survey there is a very good chance that they will no longer be running the application. Will the survey results function still run?

SQL : join with tables with same fields name (eg primary id) return invalid results

November 27, 2020, 5:20 am
$
0
0
Hi,

I noticed that if I build a query with 2 tables having the same name for primary key (and I guess this will be the case with any other field), the result is invalid as the id key in the resulting array contains only the id of the joined table.

This is for example the case in the documentation :


PHP Code:
$builder->db->table('blog');
$builder->select('*');
$builder->join('comments', 'comments.id = blogs.id');
$query = $builder->get();

// Produces:
// SELECT * FROM blogs JOIN comments ON comments.id = blogs.id 



We should have 2 id keys (I know this isn't possible in php, but the name of the result array key should be blogs.id and comments.id)


Sincerly,

Fred

Multiple Class Instances vs Function Call

November 27, 2020, 9:02 am
$
0

I have been pondering the wisdom of my methodology for a while and thought let's hear what the community has to say. I started this methodology using CI 3 and have now ported the principle to my CI4 applications
Scenario:
Developing a CRM type system and when designing the layout of the User Profile page I have to display various sections containing information from different parts of the system e.g. On the transactions tab we have two columns (1) table of all Invoices (2) table of Orders. Tab Support: Shows Tickets. Tab Technical: shows tables of Login History, Emails from the system etc.
Method 1:
At the start of the view create instances of all the Models that will be used to obtain the data e.g. InvoicesModel, OrderModel, TicketsModel etc. Then call the methods needed as and when required. E.g
Code:
<div>
<?= $modelInvoices->displayTable( $clientId); ?>
</div>
Rinse and repeat for all the information blocks. All the variables gets released once the view has been processed.

Method 2 (which I have been using):
I have created a helper function file which is loaded in BaseController. In this Wrapper Helper I have defined numerous functions that all they do is get an instance of a class and execute a method and return the result. To use the example above i Wrapper Helper:
PHP Code:
function getInvoiceTable( $clientId) {
$model = new \App\Models\InvoicesModel();
return $model->displayInvoices( $clientId);
} 
In the view the code would look something like:
Code:
<div>
<?= getInvoiceTable( $clientId ) ?>
</div>

My thinking was that using the function call the model instance is created, used and the memory released whereas with method one the memory for all the class instances are only released on completion of the view.

The reason that I brought this up that in one app the profile view is now opening 7 model classes and that could increase going forward.

All thoughts and input will be appreciated.

HI , i try to implement a filter to control if admin is authenticated :

    //--------------------------------------------------------------------

}   // End of YourFilterName Class.


i want filter every controller's method except login to prevent loop redirect

in Config/Filter this is my code:

Code:
<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class Filters extends BaseConfig
{
    // Makes reading things below nicer,
    // and simpler to change out script that's used.
    public $aliases = [
        'csrf'     => \CodeIgniter\Filters\CSRF::class,
        'toolbar'  => \CodeIgniter\Filters\DebugToolbar::class,
        'honeypot' => \CodeIgniter\Filters\Honeypot::class,
        'adminFiltersAuth' => \App\Filters\AdminFiltersAuth::class,
        'adminFiltersNoAuth' => \App\Filters\AdminFiltersNoAuth::class,
        'showSessionFilter' => \App\Filters\ShowSessionFilter::class,
    ];

    // Always applied before every request
    public $globals = [
        'before' => [
            //'showSessionFilter'
            //'honeypot'
            // 'csrf',
        ],
        'after'  => [
            'toolbar',
            //'honeypot'
        ],
    ];

    // Works on all of a particular HTTP method
    // (GET, POST, etc) as BEFORE filters only
    //     like: 'post' => ['CSRF', 'throttle'],
    public $methods = [];

    // List filter aliases and any before/after uri patterns
    // that they should run on, like:
    //    'isLoggedIn' => ['before' => ['account/*', 'profiles/*']],
    public $filters = [

        'adminFiltersAuth' => ['before' => ['admin/*'] ],
        'adminFiltersAuth' => ['except' => ['admin/login']],
        'adminFiltersNoAuth' => ['before' => ['admin/login']],



    ];
}

but if i go to ade admin/changeEmail if the admin are not logged in mut im not redirected . 
in route if i insert this code :

Code:
$routes->add('admin/changeEmail', 'Admin::changeEmail',['filter'=>'adminFiltersAuth']);

it works fine  but in some controller i want to filter every method and is too boring write a route with filter for every metods
Why ?

This is my config.php:

Suggestion for extension of controller

Hello guys.

I need some advice on CI4. In ci3 I extended the controller with the MY_controller like this:
PHP Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');


 
class MY_Controller extends CI_Controller
{
  function __construct()
  {
    parent::__construct();

  }
}

class Guest_Controller extends MY_Controller        //Controller for Not Logged (free)
{
  function __construct()
  {
    parent::__construct();

  }
}

class Logged_Controller extends MY_Controller        //Controller for ALL Logged
{
  function __construct()
  {
    parent::__construct();
    if (!$this->ion_auth->logged_in())
        {
            
            redirect('auth/login');
        }
  }
}

class Admin_Controller extends MY_Controller        //Controller for Admin
{
  function __construct()
  {
    parent::__construct();
    if (!$this->ion_auth->logged_in())
        {
            
            redirect('auth/login');
        }
        else
            {
            if(!$this->ion_auth->is_admin())
                    {
                        $this->session->set_flashdata('flashError', 'This page is only for ADMIN');
                        redirect('example_logged');
                    }
            }
    }
  
} 
so in each controller that i created, I extended the class I needed (adminController, LoggedController etc)

How can I get the same result with the BaseController? What class do I extend in my controllers, depending on whether they are admin, logged etc?

Thanks to all

can lock up environment at will

I have found that in using Fusion Auth, if I try to reregister  a user already registered the browser locks up. I can close the browser and try to start the program again but it is still locked. The line below is the line in index.php that dies. 

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

Any idea how to solve this or is this a fusion auth question?

$conn = db_connect();

$sql = "SELECT * FROM tab1 LIMIT 1";

$result = mysqli_query($conn, $sql);

$row = mysqli_fetch_assoc($result);

etc etc
}
}

In can't connect using mysqli_query... i receive this error: mysqli_query() expects parameter 1 to be mysqli, object given

I user connection in every my controller and model with no problem.

Which is the better way?
