[Solved] Custom Form Validation Only Showing The Number '1' - El Forum - 06-19-2014

[eluser]riwakawd[/eluser]
I am making my own form validation as arrays but for some reason will not display messages and also show the number '1' in the input. I also am using hmvc.

Not sure what I missed. Any Suggestions

Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Step_3 extends Controller {
private $error = array();

public function __construct() {
      parent::__construct();
      $this->load->helper('url');
      $this->load->helper('file');
      $this->load->helper('form');
      $this->load->helper('array');
      $this->load->library('form_validation');
      $this->lang->load('english', 'english');
   }

   public function index() {
    if(($this->input->server('REQUEST_METHOD') == 'POST') && $this->validate()) {
     $data['db_hostname'] = $this->input->post('db_hostname');
   $data['db_username'] = $this->input->post('db_username');
   $data['db_password'] = $this->input->post('db_password');
   $data['db_database'] = $this->input->post('db_database');
   $data['db_driver'] = $this->input->post('db_driver');
   $data['db_prefix']  = $this->input->post('db_prefix');

   $data  = $this->load->view('template/configuration/database', $data, true);
   write_file(dirname(FCPATH) . '/admin/application/config/database.php', $data, 'r+');
   write_file(dirname(FCPATH) . '/catalog/config/database.php', $data, 'r+');
   write_file(FCPATH . '/application/config/database.php', $data, 'r+');

   //$this->load->library('migration');
   //$this->migration->current();
   redirect('step_4');
    }

    $data['heading_step_3'] = $this->lang->line('heading_step_3');
  $data['heading_step_3_small'] = $this->lang->line('heading_step_3_small');

This seem to fix it.
Code:
if (array_key_exists('db_hostname', $this->error)) {
$data['error_db_hostname'] = $this->error['db_hostname'];
} else {
$data['error_db_hostname'] = '';
}

if (array_key_exists('db_username', $this->error)) {
$data['error_db_username'] = $this->error['db_username'];
} else {
$data['error_db_username'] = '';
}

if ("" == trim($this->input->post('db_hostname'))) {
$data['db_hostname'] = $this->input->post('db_hostname');
} else {
$data['db_hostname'] = 'localhost';
}

if ("" == trim($this->input->post('db_username'))) {
$data['db_username'] = $this->input->post('db_username');
} else {
$data['db_username'] = '';
}

Looks to me like you are writing some kind of installer.

The way to do it properly is to test a db connection with native PHP functions like mysqli_connect(), then write to codeigniter database config file.

Search google for codeigniter installer. You will find a sample link to github of a simpler installer.
