I tested it before posting the answer. With a fresh install, on the default page.

THE CONTROLLER

PHP Code:
<?php namespace App\Controllers;

class 
Home extends BaseController
{
    public function 
index()
    {

$rules = [
    
'id_cat.1' => 'numeric',
    
'id_cat.2' => 'numeric',
    
'id_cat.3' => 'numeric'
];

if (! 
$this->validate($rules))
{
    
print_r('error');
}
else
{
    
print_r('success');
}
        return 
view('welcome_message',['validation' => $this->validator]);
    }

    
//--------------------------------------------------------------------



First I tried to not define the keys like this:

PHP Code:
$rules = [];

if( isset(
$_POST['id_cat']) ) {
    foreach (
$_POST['id_cat'] as $id_cat_key => $id_cat_value) {
        
$rules['id_cat.'.$id_cat_key] = 'numeric';
    }
}


if (! 
$this->validate($rules))
{
    
print_r('error');
}
else
{
    
print_r('success');



It is working, but not with the first item "id_cat[0]". You should probably find a way to generate keys.

Like this:

Code:
<?php $i = 1; ?>

<form method="post">
    <input type="text" name="id_cat[<?php echo $i;$i++; ?>]" />
    <input type="text" name="id_cat[<?php echo $i;$i++; ?>]" />
    <input type="text" name="id_cat[<?php echo $i;$i++; ?>]" />
    <br><br>
    <input type="submit" value="Submit">
</form>


Then it works with a loop.

Hello.



What do you think? In helper "array_helper.php" to the method "_array_search_dot" after these lines:



PHP Code:
// Grab the current index
$currentIndex $indexes
        
array_shift($indexes)
    : 
null


Need check on index 0:

Because: if (empty($currentIndex)) ... Does not skip index 0 (string)



PHP Code:
if($currentIndex === '0' && isset($array[$currentIndex]))
    {
        return 
$array[$currentIndex];
    } 


Then in html templates you do not need to number the fields as an array ... Which, in my opinion, is more convenient ...



How do you think?

Hello mate ! Sorry for the late answer, I was on a business trip in Paris.

You can do whatever suits you but here is two remarks:
1/ It is hard for me to give you a straight answer, because I don't know what "id_cat" refers too (what is it ?), and I don't why you can't give a proper name to your fields (I don't know why you don't do "id_cat_something", "id_cat_something_else"...). I am sure there is a reason, but I don't know which one :-)
2/ Personally, I use helpers when I need it (at least) in more than one page (more than one time). But maybe you don't want to have php in your html template (which is understandable).

Hello.

There are a lot of dynamically created fields (javascript) in our project, and you can also delete them right on the page, if you number or index each one, you can go crazy), it is better if the browser does this ...In addition, the helper must skip the 0 index.

Okkk, I get it now. So you could do this, or maybe you could use Javascript to set a name when the field's value is changed. Something like... (not tested)


Code:
<input type="text" onchange="changeName()" />

function changeName() {
  var inputValue = this.value;
  this.setAttribute("name", inputValue);
}

But you will probably need to remove spaces, special chars, etc... too.

So, maybe your solution is the simplest. I don't know :-)
