Form Validation Errors Not Showing?

[eluser]Unknown[/eluser]

Code:

public function test()
    {
       $this->form_validation->set_rules('tin_number','TIN Number','required');

        if($this->form_validation->run() == TRUE)
        {
            echo $this->input->post('tin_number');
        }
       else {
        echo validation_errors();
        echo form_open();
        echo form_input('tin_number',set_value('tin_number'));
        echo form_submit('submit','Submit');
        echo form_close();
       }
      
    }

Can anyone help me figure out why this is not working?

in what it is failing?



And have you loaded the validation library?

The library checks for errors

it looks like you wanted to echo a correct value

try it the other way around, put == FALSE

and try to enter a wrong value

// Just code like this..

Code:

public function test()
    {
     $this->load->library('form_validation');
        $this->form_validation->set_rules('tin_number','TIN Number','required');

        if($this->form_validation->run() == TRUE)
        {
            echo $this->input->post('tin_number');
        }
       else {
        echo validation_errors();
        echo form_open();
        echo form_input('tin_number',set_value('tin_number'));
        echo form_submit('submit','Submit');
        echo form_close();
       }
    }

//You need to load 'form_validation' library

// Just code like this..

Code:

public function test()
{
$this->load->library('form_validation');

$this->form_validation->set_rules('tin_number','TIN Number','required');

try
{
  if(!$this->form_validation->run())
   throw new Exception($this->form_validation->error_string());
}
catch(Exception $e)
{
  echo $e->getMessage();
                echo form_open();
                echo form_input('tin_number',set_value('tin_number'));
                echo form_submit('submit','Submit');
                echo form_close();
  return;
}
}

if you load in your controller-class inside the constructor any models, check if one of the models extends the ci_controller.
Little time ago i done the mistake/fail and tried to load a model wich extends from the ci_controller.... <-- yes fail

If you do something like this, the form_validation will return a right value, but your form_validation error will not be displayed in your view.
validation_errors() will return a String with a length of 0.
