Sending view string to controller via Ajax. Codeigniter, javascript and php

Question

I’m trying to send information that is in the javascript code block to my controller, but I’m not sure how to capture the information in my controller.

Follow view Javascript code:

<script type="text/javascript">
			fetch('http://localhost/page.com.br/public/id_notification', {
				method: "POST",
				id: 1515
			})
			.then(function(response) {
				return console.log(response);
			});			

</script>

Route file:

$route['id_notification'] = 'post_notification/insert_id_post_notification';

My controller:

<?php

class Post_notification extends CI_Controller
{
    public function insert_id_post_notification()
    {
        $teste = $_POST['id'];
        var_dump($teste);
    }
}

?>

Name of my controller: post_notification.

I want to capture the id with value 1515 in my controller. Test value Thank you very much, everyone.

Passes the entire url without the route this way:

<script type="text/javascript">
                fetch('http://localhost/page.com.br/public/Post_notification/insert_id_post_notification', {
                    method: "POST",
                    id: 1515
                })
                .then(function(response) {
                    return console.log(response);
                });         

    </script>

Then in your Controller do the following

<?php

class Post_notification extends CI_Controller
{

    public function __construct() {
      parent::__construct();
    }
    public function insert_id_post_notification()
    {

        $teste = $this->input->post('id');
        var_dump($teste);
    }
}

?>

My js in view code is now as follows:

var formData = new FormData();
			formData.append('id', '1515');
            fetch('http://localhost/page.com.br/public/post_notification/insert_id_post_notification', {
                method: "POST",
                body: formData
            })
            .then(function(response) {
                return console.log(response);
            });

The POST with Ajax is OK status!

My Controller is as follows:

<?php
    class Post_notification extends CI_Controller
    {
        public function __construct() {
            parent::__construct();
        }
        public function insert_id_post_notification()
        {        
            $teste = $this->input->post('id');
            var_dump($teste);
        }
    }
?>

It’s not coming in the var_dump, so it’s not even coming in the way insert_id_post_notification controller. I don’t know why, because playing the directory I’m using in ajax right in the url I can access :/

Code with Axios js worked!

<script src="https://unpkg.com/axios/dist/axios.min.js"></script><script type="text/javascript">				axios.post('http://localhost/app.realizaconstrutora.com.br/public/id_notification', {
					id: 1515
				})
				.then((response) => {
					console.log(response.data);
		    	});
</script>
      

Thank you guys!

Use jQuery to fail

// CDN : https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js
$.post(
       'link',//url de destino
       {id: '151515'},//dados e como vao chegar no controller, para adicionar mais dados basta dar , e continuar o array
       function(data){
    //Aqui voce lida com o retorno do controller
});

Man says send it this way:

var formData = new FormData();
formData.append('id', 14);
formData.append('name', 'teste');
formData.append('valor', '1.4');

fetch('http://localhost/page.com.br/public/id_notification', {
                method: "POST",
                body: formData
            })
            .then(function(response) {
                return console.log(response);
            });
