Hello. I am trying to send an string from "View" to the "Controller" with AJAX, but give Error 403. (CodeIgniter 4)

You need to provide a lot more information than just this, before anyone can help you.
The only thing someone could point out is that a 403 is "access forbidden", if that helps.

check csrf token

Hi,

as said @mintwint you must have the CSRF enabled. In your code ajax replaces the method POST by GET and if it works it is the CSRF which has the cause. In this case, add the CSRF name and hash in the data string.

check csrf token

How should I do this?
in the $globals in config/Filters.php, csrf is commented:
public $globals = [
'before' => [
//'honeypot'
// 'csrf',
],
'after' => [
'toolbar',
//'honeypot'
],
];

View->textbox.php

Code:

<div style="text-align:center;">
    <input id="txt_short" type="text"/>
    <input id="btn_short" type="submit" value="Go" />
    <p id="show"></p>
</div>
<script>
                $(document).ready(function(){
                $("#btn_short").click(function(){
                var l =$("#txt_short").val();
                $.ajax({type:"POST",url:"../../App/Controllers/Links.php",data:"?l="+l,done:function(msg){
                    $("#show").html(data);
                        }});
                     });
                 });
</script>

Controller->Links.php

PHP Code:

class Links extends Controller
{
        public function index()
        {
                helper('html');
                helper('form');
                $p= $_POST["li"];
        }
}

I enabled CSRF and changed textbox.php View:

Code:

<div style="text-align:center;">
    <input id="txt_short" type="text"/>
    <input type="hidden" name="<?= csrf_token() ?>" value="<?= csrf_hash() ?>" />
    <input id="btn_short" type="submit" value="Go" />
    <p id="show"></p>
</div>
<script>
                $(document).ready(function(){
                $("#btn_short").click(function(){
                var l =$("#txt_short").val();
                var myObj = {csrf_test_name:"<?= csrf_hash() ?>", li:l };
                $.ajax({datatype:'json', type:'method', contentType: 'application/json; charset=utf-8', url='../../App/Controllers/links/index',data: stringify(myOBJ),done:function(msg){
                    $("#show").html(data);
                        }});
                     });
                 });
</script>

and this code is my Controller:

PHP Code:

class Links extends Controller
{
        public function index()
        {
                $security = \Config\Services::security();
                helper('security');
                helper('html');
                helper('form');
                helper('url');
                helper('text');
                return view('textbox');
        }
}

Your getting an error because your Ajax base url is wrong.

Add to your header on top at the bottom before the closing </head> tag

Code:

<!-- Pass base_url() and site_url() to JavaScript -->
<script>
    var baseUrl = "<?= base_url();?>";
    var siteUrl = "<?= site_url();?>";
</script>

Then in your ajax method add this.

Code:

// Ajax url:
url: baseUrl + "links/index",

Try that.
