Call multiple application models from a shared site in a single installation of Codeigniter 4-PHP Chinese Network Q&A

How to call models from other multi-application sites in a single installation of Codeigniter 4?

The folder structure looks like this:

- WebsiteFolder --Site1 ---app ---public --- tests --- writeable (.env, spark and other files) --Site2 ---app ---public --- tests --- writeable (.env, spark and other files) -- system

Here is my sample code:

At site 1

Constants.php I have defined a root directory to locate site2.

define('ROOTSOURCE', dirname(__DIR__,3) . '\site2');

This returns:

E:\Project\website\site2

Autoload.php

I have set up PSR4.

public $psr4 = [ APP_NAMESPACE => APPPATH, // For custom app namespace 'Config' => APPPATH . 'Config', 'Source\Models' => ROOTSOURCE . '/app/Models/' ];

Then I run the SPARK command:

php spark namespaces

and return

 --------------- ------------------ -------------------------------------------------- --------------------- -------- | Namespace | Path | Found? | --------------- ---------------------------------- -------------------------------------------------- ---- -------- | CodeIgniter | E:\Project\DennisLiu\website\system | Yes | | App | E:\Project\DennisLiu\website\site1\app | Yes | | Config | E:\Project\DennisLiu\website\site1\app\Config | Yes | | Source\Models | E:\Project\DennisLiu\website\site2\app\Models | Yes | --------------- ---------------------------------- -------------------------------------------------- ---- --------

Then find the namespace Source\Models. So far so good.

Controller=> Home.php

namespace App\Controllers; use Source\Models; class Home extends BaseController { public function index() { $setting = new \Source\Models\Setting(); return view('welcome_message'); }

When I run the controller I get:

Class 'Source\Models\Setting' not found

Next step,

At site 2

I have the modelSettings in the Site2 models folder.

Note:

Everything is working fine in Site 2.

My problem is that I get the error "Class "Source\Models\Setting"" not found"The correct settings for calling site 2 models in a single application installation of codeigniter 4 are What? . < /p>

Note: This is a single installation of codeigniter 4 for both websites. I shared the system folder.

// Create a new class manually $userModel = new \App\Models\UserModel(); // Create a new class with the model function $userModel = model('App\Models\UserModel', false); // Create a shared instance of the model $userModel = model('App\Models\UserModel');

- WebsiteFolder -- Site1 --- app --- public --- tests --- writeable (.env, spark and other file) -- Site2 --- app --- public --- tests --- writeable (.env, spark and other file) -- shared/Models (DBSetting.php) -- system

You can access the model in a class by creating a new instance or using the model() helper function.

I found the problem. This is the correct way to do this.

Folder structure

Controller - Home.php

namespace App\Controllers; use shared\Models\DBSetting; class Home extends BaseController { public function index() { $db = new \shared\Models\DBSetting(); return view('welcome_message'); } }

public $psr4 = [ APP_NAMESPACE => APPPATH, // For custom app namespace 'Config' => APPPATH . 'Config', 'shared\Models' => ROOTSOURCE . '/shared/Models' ];

Constants.php

define('ROOTSOURCE', dirname(__DIR__,3));

DBSetting.php

Namespace Sharing\Model; Using CodeIgniter\Model;

Class DBSetting extended model{

function __construct() { parent::__construct(); } public function save() { return true; }

}

We can also call the model in site 2. Just set the correct path in Autoload.php to reference the model in site 2.

Notice:If a model in site 2 contains another model or link, if we call from site 1, the codeigniter 4 system will read the link, model from site 1. So make sure to call the normal model in site 2. Or just create a shared model folder as above.
