I decided to put the validations and messages inside the HunterModel.php model. My createHunter() method inside the HunterController.php file should insert a record.

The following snippet shows the problem i'm having: Apparently $this->$data->listError();, doesn't reveal the message (or messages) i defined in $validationMessages.

• HunterModel.php

    protected $validationRules      = [
        'name_hunter' => 'required|max_length[30]',

        'height_hunter' => 'required|decimal',
        'weight_hunter' => 'required|decimal',
        'type_hunter' => 'required|max_length[30]',
        'type_nen' => 'required|max_length[30]',
        'type_blood' => 'required|max_length[3]'
    ];
    protected $validationMessages   = [
        'name_hunter' => [
            'required' => 'Hunter name cannot be empty.',
            'max_length' => 'The hunter name must have a maximum of 30 characters.'
        ],
        'age_hunter' => [

        ]
    ];

Create Validations.php in Libraries folder if it's does not exist.

Validations.php must be like:

<?php

namespace App\Libraries;

class Validations
{
   public $hunter = [
      'rules' => [
          'name_hunter' => 'required|max_length[30]',
          //other rules...
      ],
      'error' => [
          'name_hunter' => [
               'required' => 'Hunter name cannot be empty.',
               'max_length' => 'The hunter name must have a maximum of 30 characters.'
          ],
          //other error messages....
      ]
   ];
}

HunterController.php must be like:

<?php

namespace App\Controllers;

use App\Libraries\Validations;

class HunterController extends BaseController
{

public function __construct()
{
    $this->validator = new Validations();
}

public function createHunter()
{

    $response = [];
    $val = $this->validate(
         $this->validator->hunter['rules'],
         $this->validator->hunter['error']
    );
    if (!$val) {
        $response = [
           'success' => false,
            'msg' => addslashes((preg_replace('/\s /', ' ', $this->validation->listErrors())))
        ];
    }else {
        try {
        $hunter = new HunterModel();
        $data = [
            'name_hunter' => $this->request->getPost('name_hunter'),
            'age_hunter' => $this->request->getPost('age_hunter'),
