[solved]Form validation rules "lesser_than" not working

[eluser]brucebat[/eluser]
Hi all,

Code:

$this->form_validation->set_rules ('patient_weight', 'Patient Weight', 'trim|numeric|required|lesser_than[200]|xss_clean'); //if patient is heavier than 200kg return false

For some reason if I enter anything greater than 200 it still accepts it even thought it should return saying that theres an error.

Is it my syntax

XAMPP , PHP 5.0.5 dev

'less_than' not 'lesser_then'

Wow I feel really stupid now.

THanks

Just another quick question.

When validation fails, I reload my form but the values dissapear. How can I save them?

Thanks

What reload? You reload from browser or your controller? If you reload at your browser, off course it will dissapear, because you are about sending a new "fresh" HTTP request!

Sorry,

Code:

if ($this->form_validation->run() == FALSE)
                {
                    
                    $this->displayform(); //loads function that displays form
                }

And what your 'displayform' function contain? Post your whole controller is better here.

Code:

class Submit extends CI_Controller
    {
    
            public function displayform()
            {
                //prevents guest users accessing or users not logged in
                if ( $this->session->userdata('name') == FALSE)
                {
                redirect ('site/index');// to home page
                }
            
            
            $page['page'] = 'submit';
            $this->load->view('template', $page );
        
            }
    
    
            public function validateform()
            
            {
                $this->load->library('form_validation'); //loads form validation library from CI
                
                
                /*for ($i =0; $i< 30; $i++)
                {
                    $this->form_validation->set_rules('time'.$i, 'Time'.$i, 'xss_clean|required');
                    $this->form_validation->set_rules('event'.$i, 'Event'.$i, 'xss_clean|required');
                    $this->form_validation->set_rules('supplies'.$i, 'Supplies'.$i, 'xss_clean');
                    $this->form_validation->set_rules('success'.$i, 'Success'.$i, '');
                    $this->form_validation->set_rules('comment'.$i, 'Comment'.$i, 'xss_clean');
                } */
            
                $this->form_validation->set_rules ('patient_age','Patient Age','numeric|trim|required|less_than[110]|xss_clean'); //if patient is older than 110 years return false
                $this->form_validation->set_rules ('patient_gender', 'Gender', 'required');
                $this->form_validation->set_rules ('patient_weight', 'Patient Weight', 'trim|numeric|required|less_than[200]|xss_clean'); //if patient is heavier than 200kg return false
                $this->form_validation->set_rules ('patient_height', 'Patient Height', 'trim|numeric|required|less_than[220]|xss_clean');  //if patient is taller than 220 cm return false
                
                
                
                
                if ($this->form_validation->run() == FALSE)
                {
                    echo "Failed validation";
                    $this->displayform();
                }
                
                else
                
                {
                    $this->load->model('submit_model');
                    $this->submit_model->create_record();
                    if ($this == FALSE)
                    {
                        echo "Failed to add to database";
                    }
                    
                    else
                    {
                        echo "Successfully added";
                    }
                }
            }

Basically what happens is when I call the function in the same controller called "Submit" I get my validation errors but the text boxes lose their values.

Once again thankyour for your kind help

Either autoload the form validation library or put that in your controller constructor! Because with your recent code, if you put at your template/view file, this line

Code:

<?php echo set_value('username') ?>

What happens is, your pseudo variable at view file, on displayform function, try to find a value from form_validation library object which unfortunately, not available (because you didnt auto load or put that in your controller constructor).

Code:

function __construct()
{
  parent::__construct();
  $this->load->library('form_validation');
}
