Filters and $_POST (or $request post vars)

I want to automatically add variables to each incoming POST, so I thought filters would be helpful, however, I can't see a way to get to the POST vars in the filter class

PHP Code:

class Filters extends BaseConfig
{
 
 public $aliases = [
 'csrf'    => CSRF::class,
 'toolbar'  => DebugToolbar::class,
 'honeypot' => Honeypot::class,
 'postfilter' => PostFilter::class
 ];
 public $globals = [
 'before' => [
 // 'honeypot',
 // 'csrf',
 ],
 'after'  => [
 'toolbar',
 // 'honeypot',
 ],
 ];

 public $methods = [
     'post' => ['postfilter']
    ];

 public $filters = [];
} 


the PostFilters class:

PHP Code:

class PostFilter implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        $_POST['Maint_Userid'] = "plugh";
        $_POST['Create_Userid'] = "plugh";
        return $request;
    }

    public function after(RequestInterface $request, ResponseInterface $response, $arguments = null)
    {
        // Do something here
    }
} 


I've also tried:

PHP Code:

public function before(RequestInterface $request, $arguments = null)
    {
        $post_request = \Config\Services::request();
        $post_request->Maint_Userid = "plugh";
        $post_request->Create_Userid = "plugh";
        return $request;
    } 


PHP Code:

public function before(RequestInterface $request, $arguments = null)
    {
        $request['Maint_Userid'] = "plugh";
        $request['Create_Userid'] = "plugh";

        return $request;
    } 


(and a few other variations of the above)

It is adding the varaibles to the RequestInterface $request (from log_messages, I see this). Even the direct $_POST didn't add it to the post vars in the controller.
Where should I be doing this (or how do I make the filters see the $_POST vars and add to them)?
Thanks.

Try using $_REQUEST['Maint_Userid']... or whatever the form/post variable's name it is you want to access from inside the Filter.

Code:

public function before(RequestInterface $request, $arguments = null)
    {
        $maint_Userid = $_REQUEST['Maint_Userid'];
        $create_Userid = $_REQUEST['Create_Userid'];
        ...

Try using $_REQUEST['Maint_Userid']... or whatever the form/post variable's name it is you want to access from inside the Filter.

Code:

public function before(RequestInterface $request, $arguments = null)
    {
        $maint_Userid = $_REQUEST['Maint_Userid'];
        $create_Userid = $_REQUEST['Create_Userid'];
        ...

That would get me the values in the POST. I'm looking to *add* values to the POST for processing (as in, for each POST, I want to add the user's ID for both the create and maint fields)

[quote pid="389059" dateline="1627911401"]
you need api ctl other ctl extend from it  after log in call $userId

you dont need add data to post request

Enlightenment  Is  Freedom

Actually, I've sorted out the issue that I needed to sort out. I really didn't need the vars as part of the POST, I needed them to be automatically filled in when I submitted my records for insert or update to the database, so, the database beforeInsert and beforeUpdate fixed the issue (in the model):

PHP Code:

namespace App\Models;

use CodeIgniter\Model;

class EmployeeCOIModel extends OurModel
{
    protected $DBGroup      = 'db_group1';
    protected $table        = 'Employee_COI';
    protected $allowedFields = [
 // our fields go here
       'Maint_Userid',
        'Maint_Date',
        'Create_Userid',
        'Create_Date'              
    ];

    protected $beforeInsert = ['setInsertFields'];
    protected $beforeUpdate = ['setUpdateFields'];
    protected $returnType    = 'App\Entities\EmployeeCOI';

    protected function setInsertFields(array $data)
    {
        if (!isset($data['data']['Create_Userid'])) {
            helper("user");
            $request = \Config\Services::request();
            $current_user = get_user($request->getServer('AUTH_USER'));
            $data['data']['Create_Userid'] = get_username($current_user);
            $data['data']['Maint_Userid'] = get_username($current_user);
        }
        return $data;
    }
    protected function setUpdateFields(array $data)
    {
        if (!isset($data['data']['Maint_Userid'])) {
            helper("user");
            $request = \Config\Services::request();
            $current_user = get_user($request->getServer('AUTH_USER'));
            $data['data']['Maint_Userid'] = get_username($current_user);
        }
        return $data;
    }
}
