Hi all,

I'm using the form validation tutorial to get my forms working. I don't get errors back if I enter wrong data, and I don't get success if I enter right data.

This is what I did (exactly what the tutorial described).

Controller form.php:

Code:
&lt;?php

class Form extends CI_Controller {

 function index()

 {

  $this->load->helper(array('form','url'));

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

  $this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]');

  $this->form_validation->set_rules('password', 'Password', 'required');

  $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');

  $this->form_validation->set_rules('email', 'Email', 'required|valid_email');

  if ($this->form_validation->run() == FALSE)

  {

     $this->load->view('myform');

  }

  else

  {

     $this->load->view('formsuccess');

  }

 }

}

?&gt;

View myform.php:

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;My Form&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?php echo validation_errors(); ?&gt;

&lt;?php echo form_open('form'); ?&gt;

<h5>Username</h5>

&lt;input type="text" name="username" value="" size="50" /&gt;

<h5>Password</h5>

&lt;input type="text" name="password" value="" size="50" /&gt;

<h5>Password Confirm</h5>

&lt;input type="text" name="passconf" value="" size="50" /&gt;

<h5>Email Address</h5>

&lt;input type="text" name="email" value="" size="50" /&gt;

<div>&lt;input type="submit" value="Submit" /&gt;&lt;/div>

&lt;/form&gt;

&lt;/body&gt;

&lt;/html&gt;

View formsuccess.php:

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;My Form&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h3>Your form was successfully submitted!</h3>

<p>&lt;?php echo anchor('form', 'Try it again!'); ?&gt;</p>

&lt;/body&gt;

&lt;/html&gt;

I searched everywhere for solutions, and found issue #177, but the solution from github didn't help.

In a debugging session I found in library Form_validation.php in "function set_rules" and in "function run" the following statement:

Code:
....

  if (count($_POST) == 0)

  {

   return FALSE;

  }

....

This statement always returns FALSE, even if I enter correct data in the form fields.

Can anyone help me please?

Regards,

Carmen

<form name="myfrm" method="post">
</form>
