CI4 use model's method in view

Hi ,sorry for engish , in ci3 if i have a model call codeigniterModel with a method call findById($id) 

in controller i load model with :

PHP Code:

$this->load->model('codeigniterModel') 


and in view i can use   $this->codeigniterModel->findById($id) method 

how can i do the same on ci4 ?

Hello !

You can do it like this:

PHP Code:

<?php namespace App\Controllers;

use CodeIgniter\Controller;

// use u model class.
use App\Models\codeigniterModel;

class MyController extends Controller
{
    public function index()
    {
        // create instance u model.
        $CI_Model = new codeigniterModel();

        // call the method from model
        echo $CI_Model->findById($id);
    } 


p.s. Sorry my English.

I want use in a view not in a controller....

Then you just need to slightly modify the code in the controller itself like this:

PHP Code:

...here everything that I wrote above...
// create instance u model.
$CI_Model = new codeigniterModel();
// create new data "storage"
$data = [
     'result_query' => $CI_Model->findById($id)
];
// passing data to view
echo view("your_view_file", $data); 


Further, in the view file itself, you need to call the data simply by accessing the key:

PHP Code:

<?= $result_query; ?>

no,you don't understand  , i want use model's functions in view , as ci3 .....
for example : in db table there are foreign key , in  the page where i show the list , i cannot write the id of the foreign key but i must insert for example the name ...
