[eluser]BenRob[/eluser]

please please please can someone help

Code:

$this->load->library('form_validation');
  $this->load->helper('cookie');

  $data = array();


  if($_POST) {
   // Set validation rules including additional validation for uniqueness
   $this->form_validation->set_rules('yourname', 'Your Name', 'trim|required');
   $this->form_validation->set_rules('youremail', 'Your Email', 'trim|required|valid_email');
   $this->form_validation->set_rules('friendname', 'Friends Name', 'trim|required');
   $this->form_validation->set_rules('friendemail', 'Friends Email', 'trim|required|valid_email');

   // Run the validation and take action
   if($this->form_validation->run()) {
    echo 'valid';
   }
  }
  else{
   echo 'problem';
  }

Can you be more specific about what the problem is?

[eluser]BenRob[/eluser]
the validation just isn't running

When i submit the form i get 'problem' echoed

I've tried to take it right back to find the problem and a simple valid or problem shows the validation is not working

Any ideas its killing me

You need to setup youre view where the form is..
there you need to add the 'error views'.

Just add this in youre view where youre form is:

Code:

<?php echo validation_errors(); ?>

Yes, you can seperate it, look at the user guide for that


And youre controller:

Code:

<?php  
  $this->load->library('form_validation');
  $this->load->helper('cookie');


   // Set validation rules including additional validation for uniqueness
   $this->form_validation->set_rules('yourname', 'Your Name', 'trim|required');
   $this->form_validation->set_rules('youremail', 'Your Email', 'trim|required|valid_email');
   $this->form_validation->set_rules('friendname', 'Friends Name', 'trim|required');
   $this->form_validation->set_rules('friendemail', 'Friends Email', 'trim|required|valid_email');
   $this->form_validation->set_error_delimiters('<div class="error">','</div>');

  if($this->form_validation->run() == FALSE)
  {
      
    $this->load->view('Youre_Form_View');    
  }
  else
    {
      // do something..    
    }

That doesn't mean it's not running, it just means that it's not passing validation... What if you put:

Code:

echo validation_errors();

instead of 'problem'?

Noctrum..

it is a 'problem' when it's not running
Just joking..

remove your $_POST condition.

or try this...

Code:

$this->load->library('form_validation');
  $this->load->helper('cookie');

  $data = array();


  if(!empty($_POST)) {
   // Set validation rules including additional validation for uniqueness
   $this->form_validation->set_rules('yourname', 'Your Name', 'trim|required');
   $this->form_validation->set_rules('youremail', 'Your Email', 'trim|required|valid_email');
   $this->form_validation->set_rules('friendname', 'Friends Name', 'trim|required');
   $this->form_validation->set_rules('friendemail', 'Friends Email', 'trim|required|valid_email');

   // Run the validation and take action
   if($this->form_validation->run()) {
    echo 'postback: validation ok';
   }
else {
echo 'postback: validation error';
}
  }
  else{
   echo 'no postback: problem';
  }
