Continuous Loop in form validation

[eluser]yorvik[/eluser]
Hello I have this litte code where I update value of the database with jquery AJAX.

Code:

class Art_controller extends Controller {

    function input() {
        $this->load->helper('form');
        $this->load->helper('html');
        $this->load->model('art_model');

        $query = $this->art_model->get_records($this->uri->segment(3));

        if ($query) {
            $data['records'] = $query;

            $data['main_content'] = 'editwork_form';
            $this->load->view('includes/template', $data);
            
        }
    }

    function submit()
    {
        //load form validation
        $this->load->library('form_validation');
        $this->load->model('art_model');
        //set form rules
        $this->form_validation->set_rules('kunstwerk', 'Kunstwerk', 'trim|required|min_length[5]');
        

        //run form validation
        $success = $this->form_validation->run();

        //if the validation was a success
        if ((IS_AJAX && $success) || (!IS_AJAX && $success)) {
            echo "Congradulations, your form was accepted!";
            $data = array(
                        'schilderijNaam' => $this->input->post('kunstwerk'),
                        'kunstenaarId' => $this->input->post('kunstenaarID')
                    );
            $this->art_model->edit_record($this->uri->segment(3), $data);
        }
        //if validation failed
        else {
            echo strip_tags(validation_errors());
        }
    }
}

Now i load this view: (but when I typ $artwork less than 5 caracters I get in an continous loop) I want my errors to be showed but that is not the case. Can someone help?

Code:

<h1>Edit artwork!</h1>
<fieldset>
    <legend>Art information</legend>
    &lt;?php
    $attributes = array('id' => 'myForm');
    echo form_open('art_controller/submit/' . $this->uri->segment(3), $attributes);

    if (isset($records)) : foreach ($records as $row) :
    ?&gt;
    &lt;?php
            echo '<label for="kunstwerk">Kunstwerk: </label>' . form_input('kunstwerk', set_value('kunstwerk', $row->schilderijNaam));
            echo '<label for="kunstenaarId">Kunstenaar: </label>' . form_input('kunstenaarId', set_value('kunstenaarId', $row->kunstenaarId));
            echo '<label for="categorieId">Categorie: </label>' . form_input('categorieId', set_value('categorieId', $row->categorieId));

            echo '<label for="oplage">Oplage: </label>' . form_input('oplage', set_value('oplage', $row->oplage));

            echo '<label for="afmetingen">Afmetingen: </label>' . form_input('afmetingen', set_value('afmetingen', $row->afmetingen));
            echo '<label for="prijs">Prijs: </label>' . form_input('prijs', set_value('prijs', $row->prijs));

            $dataTextarea = array(
                'name' => 'infoNL',
                'id' => 'infoNL',
                'value' => set_value('infoNL', $row->infoNL),
                'rows' => '5',
                'cols' => '32'
            );

            echo '<label for="infoNL">Info NL: </label>' . form_textarea($dataTextarea);


            $dataTextarea = array(
                'name' => 'infoNL',
                'id' => 'infoNL',
                'value' => set_value('infoEN', $row->infoEN),
                'rows' => '5',
                'cols' => '32'
            );
            echo '<label for="infoEN">Info EN: </label>' . form_textarea($dataTextarea);

            echo '<label for="datum">Date: </label>' . form_input('datum', $row->datum);

            echo form_submit('submit', 'Edit Work', 'id="submit"');
            echo form_close();
    ?&gt;
        
    &lt;?php endforeach; ?&gt;
    &lt;?php else : ?&gt;
            
                <h2>No records were returned</h2>            
            
    &lt;?php endif; ?&gt;
                <div id="error"></div>            
            </fieldset>            
            
            [removed]            
                $(document).ready(function() {            
                    $("form").submit(function(e) {            
                        e.preventDefault();            
                        v_kunstwerk = $('input[name="kunstwerk"]').val();            
                        v_kunstenaarID = $('input[name="kunstenaarId"]').val();            
                        v_categorieID = $('input[name="categorieId"]').val();            
                        v_oplage = $('input[name="oplage"]').val();            
                        v_prijs = $('input[name="prijs"]').val();            
                        v_date = $('input[name="datum"]').val();            
                                  
                        if (v_kunstwerk != null) {            
                            $.ajax({            
                                url: 'http://localhost/codeIgniter/index.php/art_controller/submit/&lt;?php echo$this->uri->segment(3); ?&gt;',
                    type: 'POST',
                    data: {
                        kunstwerk: v_kunstwerk,
                        kunstenaarID: v_kunstenaarID,
                        categorieID: v_categorieID,
                        oplage: v_oplage,
                        prijs: v_prijs
                    },
                    success: function(data) {
                        alert(data);
                        
                        $('#error').text(data);
                    }
                });
            }
            
        });

    });
