Codeigniter – Code Igniter form_validation load fatal error

codeigniter

I am using code igniter 2.0.3.

When I try loading form_validation in my controller $this->load->library('form_validation'), I get an error message:

Fatal error: Call to a member function set_rules() on a non-object in D:\Installation\xampp\htdocs\MyApp\application\controllers\login.php on line 44

On line 44 in login.php, this is what I have:

$this->form_validation->set_rules('name', 'Name', 'trim|required');

When I load form_validation in autoload.php, there are no errors.

Why is this happening?

The only way I could reproduce that error was to flip-flop the position of library and the validation:

Causes Error -
$this->form_validation->set_error_delimiters('name', 'Name', 'trim|required');
$this->load->library('form_validation');

Works -
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('name', 'Name', 'trim|required');

You're calling a method of the class before the class is loaded. This would also explain why autoloading the validation produced no error for you.

Codeigniter – Why is this constructor failing to load in Code Igniter

It should be this...

<?php
class Blog extends CI_Controller {

    function __construct() {
        parent::__construct();
    }

}

The tutorial you are probably going through is based on 1.7.2 which had a core of php4 which did not use the php5 __construct() method of building Class constructors. Codeigniter 2.0.0 has a php5 core and uses it.

Php – Fatal error: Uncaught ArgumentCountError

You must pass an ID with the button to function in the controller like this.

 <a href="<?php echo base_url("personel/update_form/".$row->id); ?>" class="btn-sm btn-warning">Update </a>
