Form validation required not firing

hello,

I've been trying for a few hours to implement the validation form, but at runtime nothing happens.

this is my form :

Code:

<?php include_once 'header.php';?>


<div class="container">
        <div class="card card-container">
           <!-- <img class="profile-img-card" src="//lh3.googleusercontent.com/-6V8xOA6M7BA/AAAAAAAAAAI/AAAAAAAAAAA/rzlHcD0KYwo/photo.jpg?sz=120" alt="" /> -->
           <img id="profile-img" class="profile-img-card" src="//ssl.gstatic.com/accounts/ui/avatar_2x.png" />
           <p id="profile-name" class="profile-name-card"></p>

           <form name="Login_form" class="form-signin" method="post" action="<?php echo base_url('login_controller/login_pro');?>" >
             
               <input type="text" name="Username" class="form-control" placeholder="Username" >
               <input type="password"  name="Password" class="form-control" placeholder="Password" >
               <div id="remember" class="checkbox">
                   <label>
                       <input type="checkbox" value="remember-me"> Remember me
                   </label>
               </div>
               <button class="btn btn-lg btn-primary btn-block btn-signin" type="submit">Sign in</button>
           </form><!-- /form -->
           <a href="#" class="forgot-password">
               Forgot the password?
           </a>
       </div><!-- /card-container -->
   </div><!-- /container -->

   <?php include_once 'footer.php';?>

and this is my controller :

Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login_controller extends CI_Controller {

    public function index()
    {
        echo 'welcome to login';
    }

    function login_pro()
    {
        /*echo $user = $this->input->post('user');
        echo $pass = $this->input->post('pass');*/



        $this->form_validation->set_rules('Username','Username','required');
       
        $this->form_validation->set_rules('Password','Password','required');

        
    }
}

I had activated the url and form helper, and also the form_validation library in the autoload file.

thank you in advance.

You have forgotten to include the RUN function*. You should have a go with this tutorial first:
https://www.codeigniter.com/user_guide/l...n-tutorial

* $this->form_validation->run()

I introduced the function RUN (), but it did not change anything :

Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login_controller extends CI_Controller {

    public function index()
    {
        echo 'welcome to login';
    }

    function login_pro()
    {
        /*echo $user = $this->input->post('user');
        echo $pass = $this->input->post('pass');*/

        $this->form_validation->run();

        $this->form_validation->set_rules('Username','Username','required');
       
        $this->form_validation->set_rules('Password','Password','required');

          if ($this->form_validation->run() == FALSE)
               {
                       echo 'try again';
               }
               else
               {
                       echo 'welcome';
               }
    }
}

You need to read the tutorial again, now you got two RUN() functions.
Start fresh and just copy that code before you try to introduce your code.

same, I introduced a single function, but it still does not block when the fields are empty

Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login_controller extends CI_Controller {

    public function index()
    {
        echo 'welcome to login';
    }

    function login_pro()
    {
        /*echo $user = $this->input->post('user');
        echo $pass = $this->input->post('pass');*/

        $this->form_validation->set_rules('Username','Username','required');
       
        $this->form_validation->set_rules('Password','Password','required');

          if ($this->form_validation->run() == FALSE)
               {
                       echo 'try again';
               }
               else
               {
                       echo 'welcome';
               }
    }
}

Here's the tutorial, try it with a fresh copy of Codeigniter. (It works)

You can tell CI to log everything it's doing by changing:
/application/config/config.php
$config['log_threshold'] = 4;

Logs are in:
/application/logs/

hello,

your solution works, but not my form.

I rerun my form with logging enabled. and that generated me the log file as an attachment.

Hi in the controller you need to ensure that the library and necessary helpers are loaded:

PHP Code:

public function login_pro()
    {
        /*echo $user = $this->input->post('user');
        echo $pass = $this->input->post('pass');*/
      
       // Loading helpers and library
       $this->load->helper(array('form', 'url'));
       $this->load->library('form_validation');


        $this->form_validation->set_rules('Username','Username','required');
        
        $this->form_validation->set_rules('Password','Password','required');

          if ($this->form_validation->run() == FALSE)
               {
                       echo 'try again';
               }
               else
               {
                       echo 'welcome';
               }
    } 


I've already done that, but without success

OK!
I've taken the code you have pasted in and created a brand new installation of CI 3.1.8

In order to get this thing working i had to do 2 changes to your code:

1, in the form i've changed base_url() to site_url()
2, see the example class

PHP Code:

<?php
class Test extends CI_Controller {

    public function __construct() {
        parent::__construct();
        // Loading helpers and library
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');
    }

    function login_pro() {

        $this->form_validation->set_rules('Username', 'Username', 'required');
        $this->form_validation->set_rules('Password', 'Password', 'required');

        if ($this->form_validation->run() == FALSE) {
            echo 'try again';
        } else {
            echo 'welcome';
        }
    }

} 


Now, this is working fine on linux on PHP 7.2.5

Personally i do not like the case sensitive name tags in the form, so if it would be up to me u would rename Username to username, but that is just my preference..
