im new on codeigniter and try to resolve following problem for hours now.
I try to set_value in a form but when i set it i get following error:
A PHP Error was encountered
Severity: Error
Message: Call to undefined function set_value()
Filename: modals/register_modal.php
Line Number: 27
Backtrace:
When i delete set_value() on line 27, everything works fine.
Line number 27 is the set_value() line:
<div class="row">
<div class="form-group">
<label class="control-label sr-only">Vorname:</label>
<div class="col-md-8 col-md-offset-2 col-xs-10 col-xs-offset-1">
<input type="text" class="form-control" name="firstname" placeholder="Vorname" value="<?php echo set_value('firstname'); ?>" size="50" />
<i class="fa form-control-feedback" aria-hidden="true"></i>
</div>
</div>
</div>
Thats my controller:
class Form extends CI_Controller {
public function index()
{
$this->load->helper('form');
$this->load->library('form_validation');
$this->form_validation->set_rules('firstname', 'Vorname', 'required|callback_username_check');
$this->form_validation->set_rules('surename', 'Nachname', 'required');
$this->form_validation->set_rules('email', 'Email', 'required');
$this->form_validation->set_rules('password', 'Passwort', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->load->view('modals/register_modal');
}
else
{
$this->load->view('modals/login_modal');
}
}
public function username_check($str)
{
if ($str == 'test')
{
$this->form_validation->set_message('username_check', 'The {field} field can not be the word "test"');
return FALSE;
}
else
{
return TRUE;
}
}
}
I also set Auto-Load:
$autoload['helper'] = array('form');
You must load library('form_validation') in your Controller.
This work for me:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Login extends CI_Controller{
public function __construct(){
parent::__construct();
$this -> load -> library('form_validation');
}
....
In CodeIgniter4 you have only to use the helper function to load the library
<?php namespace App\Controllers;
use App\Models\UserModel;
class Users extends BaseController {
public function index()
{
helper (['form']);
......
Add helper HTML
protected $helpers = ['form','url','html'];
It worked for me
You can add form helper in BaseController.php. you don't need to add in every cotnroller - codeigniter 4
Edit in BaseController.php
protected $helpers = ['form'];
helper(['form']);
Load the form helper in your function

Array keys in PHP are case sensitive.
I think if you change $row['FIRST'] to $row['first'] the issue will be solved!

Please follow the below steps:
1. You need to load 'url_helper' in autoload file and its a best practice instead of writing in every page. path(application > config > autoload.php)
$autoload['helper'] = array('url');
2. You need to add below line in top of the view page.
<base href="<?php echo base_url(); ?>">

I am writing a page for the admin panel i am making that lists member results. I want to have a search form on this page to search for certain members. Since I have other forms on this page, the action of this search form has to be in a different method in my controller. The problem is that none of the post values are being transmitted to the search method. What am i doing wrong?
class Users extends MY_Controller {
function __construct(){
parent::__construct();
}
function index(){
if(!$this->form_validation->run()){
$this->load->view('users/index');
}
}
function search(){
$criteria = $this->input->post('search_criteria');
}
}
This is something like what my view would be:
<?php echo form_open('users/search'); ?>
<input type="text" name="search_criteria">
You have no form validation rules and form validation was on wrong function
class Users extends MY_Controller {
function __construct(){
parent::__construct();
$this->load->library('form_validation');
$this->load->helper('form');
$this->load->helper('url');
}
function index(){
// There is no need to use index on your view files.
$this->load->view('users');
}
function search(){
$criteria = $this->input->post('search_criteria');
$this->form_vadliation->set_rules('search_criteria', 'Search', 'required');
if($this->form_validation->run() == FALSE) {
// There is no need to use index on your view files.
$this->load->view('users');
} else {
// Success Stuff
}
}
}
View application > views > users.php
<?php echo validation_errors('<div class="error">', '</div>'); ?>
<?php echo form_open('users/search'); ?>
<input type="text" name="search_criteria" value="" class="" placeholder="" />
<input type="submit" value="Save" />

this line-> <<?php echo $heading;?>
How I can pass the data to another view?
In your controller, change
$this->load->view('register/register_open',$data)
to
$this->load->view('register/register_open',array('data' => $data));
When you do $this->load->view('view', $variable) it takes $variable and uses the php function extract() to turn the array keys into variables. So, if you want to use the variable $data in a nested view, you have to send another array like I did above.
