Hello folks,
Does anyone know that if I put some codes in app/Config/App.php

PHP Code:
public function __construct()
    {
 parent::__construct();
 $services = new Services();

does this get called at every request or when apache is restarted ?

≪ Previous: using app/Config/App.php in CodeIgniter 4

Hi all,
Using v4.6.1 - in app/Config/Cookie.php - after changing samesite setting to 'None'

PHP Code:
    public string $samesite = 'None'; 

Console error is:

Quote:Cookie “pm_id” has been rejected because it is in a cross-site context ...

Still get cross-site errors. I'm doing this for testing, connecting to the remote CI4 server from localhost on local machine.

I've tried using Cookie helper to no avail-:

PHP Code:
helper('cookie');
 set_cookie('session_id', '', 3600, '','', true, true, 'None'); 

Is it possible to force samesite to 'None' for the CI session cookie?

Many thanks,
Mike

≪ Previous: Changing Session cookie - samesite v4.6.1

In my app I have 2 email address fields.

The first field is required because it's the main account.

The second field is optional.

Here are my rules currently.

PHP Code:
public $profile = [
    'login_email' => ['label' => 'Login Email', 'rules' => 'required|valid_email'],
    'login_email_2' => ['label' => '2nd Login Email', 'rules' => 'valid_email'] 
]; 

But when I leave the login_email_2 field blank it complains that it's not a valid email.

How can I ignore the valid email rule if the field is blank?

I think I solved my own problem with permit_empty

Is there a listing of all the codeigniter validation rules?

I didn't see them singled out in the docs.

Hi All,

CI 4.6.1.

I am trying to add a new column to an existing table. I am not having any luck.

PHP Code:
        $val                  = array();
        $obj['email_private'] = $this->getEmailField();
        $val                  = $obj['email_private'] + ['after' => 'email_public'];
        $this->forge->addColumn('entry_requests', $val); 

getEmailFields looks like

PHP Code:
    protected function getEmailField()
    {
        $str = ['type' => 'VARCHAR', 'constraint' => '128', 'DEFAULT' => ' ', 'null' => 'false',];
        return $str;
    } // end of method 

The error I am getting is an exception inside forge->addField. It seems that for some reason, it doesn't like the VARCHAR part of the definition. It throws a "Field information is required for that operation." exception, from line 387.

The variable $val contains:

type = "VARCHAR"
constraint = "128"
DEFAULT = " "
null = "false"
after = "email_public"

I don't see what I have done wrong and cannot find the error on the internet to track it down further.

Any help is much appreciated.

Hi team,
I have a new issue that is confusing me
Using CodeIgnighter4, I have routes set up :
$routes->get("Entry/(:any)",'Home::Entry/$1');
$routes->get("LoadEvents/(:any)",'Home::Load_Events/$l/$2');

In the Controller:
public function Entry($Hive_ID,$Entry_ID){ blah blah....}
public function Load_Events($BeeKeeper_ID,$mth){
echo "$BeeKeeper_ID<br>";
echo "$mth<br>";

The Entry route works without issue... (tested from the application and from postman)
The Load_Events route echoes $1 as $BeeKeeper and nothing for $mth

Can anyone shed some light on this behaviour ?

I have tried
$routes->get("LoadEvents/(:any)",'Home::Load_Events/$l');
$routes->get("LoadEvents/(:any)/(:any)",'Home::Load_Events/$l/$2');
as well to no avail...

Any assistance will be appreciated.

≪ Previous: Route passing $1 into the controller function instead of the value

Hi Team,
In our ci3 app we supply an external service with a web_url so they can take a copy of one of our files and analyse it before giving us a decision about its suitability for our site.
In ci4 I have used exactly the same idea but the 3rd party is saying they receive a 404 response so we are not getting good responses.
If I try to view the file in question by using the url I too get 404 but with a clue that the GET route is not defined.
eg https://www.mysite.com/images/uploads/te.../image.jpg
I have reviewed the routing docs and the smart file handling docs but am a bit mystified about how to enable this file to be retrieved externally.
I'm sure its easy but I cannot find the magic bullet ... yet.
Any clues appreciated, thx Paul

How to Use CodeIgniter Global Functions (e.g., helper(), model()) Inside Custom "Mana

May 23, 2025, 10:15 am

≫ Next: CI Shield setup: can't connect to database

≪ Previous: external request for a file gives 404

Hi everyone,
I'm working on a project where I'm using an MVCM (Model-View-Controller-Manager) pattern. Here's how I’ve structured it:

Model: Represents the database table.
Entity: Represents a single row of the table.
Manager: Contains the business logic that coordinates between models and entities.
Controller: Talks to the Manager, which then handles the lower-level details.

I've created a Managers directory inside app/ , and I intend for my controllers to interact only with Managers — not directly with Models or Entities.
The issue: inside the Manager classes, I’m unable to use common global functions like helper(), model(), etc., that work seamlessly in Controllers.

Question:
Is there a way to make these global CodeIgniter functions available inside my custom Managers classes, just like they are in Controllers?

Thanks in advance!

I've run into a problem that is driving me nuts. I installed CI4.6.1 and everything went as expected. I need an authentication system, so I turned to CI Shield. Followed the docs and installation seemed to run smoothly. And that's when things went south: ran the setup through spark - everything worked until the last step and this got thrown at me:

Code:
Running all new migrations...

[CodeIgniter\Database\Exceptions\DatabaseException]

Unable to connect to the database.

Main connection [MySQLi]: No such file or directory

at SYSTEMPATH/Database/BaseConnection.php:467

I double checked my database config and everything seemed to be fine:

Code:
public local -> array (20) [

        'DSN' => string (0) ""

        'hostname' => string (9) "localhost"

        'username' => string (4) "root"

        'DBDriver' => string (6) "MySQLi"

        'DBPrefix' => string (0) ""

        'pConnect' => boolean false

        'DBDebug' => boolean true

        'charset' => string (7) "utf8mb4"

        'DBCollat' => string (18) "utf8mb4_general_ci"

        'swapPre' => string (0) ""

        'encrypt' => boolean false

            'datetime' => string (11) "Y-m-d H:i:s"

            'time' => string (5) "H:i:s"

        ]

]
I changed "localhost" to "127.0.0.1", just as a test and tried running the migration again, and got the same result. I checked the connection with both the CLI and a PHP script and had no issues.
I'm using MAMP as my development enviroment, and it's running PHP8.3.9 and MySQL8.0.35.
Any suggestions or pointers in the right direction would be greatly appreciated.

≪ Previous: How to Install CodeIgniter 4 on Local Machine – Step-by-Step Guide

Hi all,
After installing CodeIgniter 4, the next important step is setting up your database connection. Here’s how you do it:

Open

Code:
app/Config/Database.php
file.
Update the

Code:
$default
group settings with your database credentials (hostname, username, password, database name).
Make sure the database driver matches your DBMS (e.g., MySQLi for MySQL).
Save the file and test your connection by running a simple model query.

If you want to use environment variables for better security, CodeIgniter supports that too! Just edit the

Code:
.env

file at the root and set your DB credentials there.
Let me know if you want me to share sample code snippets or troubleshoot errors.

Hi there,
Greetings to all as this is my first post.
I am a complete novice at this business of frameworks.
I would like to start learning and using CodeIgniter as I have read many positive reviews about it.
Though I have developed applications using php but none have utilised the MVC principles.
I have tried to learn programming by myself using examples and snippets of codes, and always try to adhere to best practice.
I would appreciate if seasoned CI developers answer a very fundamental question for me:
The question is about re-using libraries, classes, functions, etc., in a modular framework environment.
[which I suppose could be applicable to all PHP frameworks, not necessarily to CI]
Let's say that you are developing a project that needs a good search function in it.
Now you come across an open-source application and/or you have purchased an application that has got that 'desirable' search facility built in it.
Can I re-use that in my project?

Thank you in advance for any helpful suggestion and/or advice.

(https://prnt.sc/x0S_mf47G4c4). File showing corrupted on ios/mac/apple and gmail also.
I have checked the file path, it's correct and same file works fine in inline mode.
I tried the followings, but doesn't worked

PHP Code:
1. $email->attach($attachment, 'attachment', basename($attachment), 'application/pdf');

$email->attach($tempPath, 'attachment', 'document.pdf', 'application/octet-stream'); 

I am sending dynamically created pdf, which creates on server, then I send it in email. I also tried putting the static PDF on server, that too doesn't worked.
below is my code to send email, please help to resolve this issue.

Alternative multisite structure - problems? concerns?

≫ Next: Call to a member function get() on null Error

≪ Previous: PDF attachment download not working in email in IOS/MAC/APPLE

I wanted to accomplish in CI4 what I was doing in CI3 - have a system folder that was shared by multiple sites/projects and upgrade them individually as their code became (or was confirmed as) ready for the new version.

Using this approach, when a new release of CI3 was available, I would immediately install the new framework, but this wouldn't affect any existing code. Only when I was ready, I would point a site/project to the new system code, and I could revert that immediately and fully if something failed in a major way.

I think I have this working in CI4, but I'd like to know if anyone sees problems or concerns with how I'm doing this now. Life's been too busy for me to deal with upgrading things from CI3, but I'm now at a point where I can't delay further, thus the timing of this question.

In the following, structures assume a manual installation. I don't use Composer and have no idea how this would impact Composer-installed CI4.

The differences between how I'm doing this and what the documentation suggests are file organization and using an absolute path to the system folder in Config/Paths.php

The documentation suggests the following structure for a manually-installed multi-site CI4:

Code:
foo/

    app/

    public/

    tests/

    writable/

    env

    phpunit.xml.dist

    spark

bar/

    app/

    public/

    tests/

    writable/

    env

    phpunit.xml.dist

    spark

codeigniter4/system

My approach, allowing multiple CI4 system/core versions, looks like this:

Code:
foo/

bar/

ci4_5_8/

ci4_6_0/

ci4_6_1/

(I'm actually starting at 4.6.1, so the older versions there are just for illustration.)

In Paths.php I have:

Code:
public string $systemDirectory = '/server/projects/ci4_6_1';

I think this explains enough, but let me know if you have questions about what I mean. My question is: are there any risks (especially regarding security or stability) here that I should be wary of? It seems like a straightforward variation, but dealing with framework code that I don't have time to analyze in depth makes me a little nervous about variations.
