form validation

[eluser]maniac[/eluser]
I am trying to do a login to an administration section on a website using codeigniters validation, but keep coming up with errors -

Undefined property: CI_Loader::$validation

Trying to get property of non-object

both on my view page, but can't seem to see where I have gone wrong (reading user guide for libraries and validation), so any help would be appreciated.

My view page -

Code:

<?php echo $this->validation->error_string; ?>
  
      <?php echo form_open('form'); ?>
  
      <p>User Name
      &lt;input type="text" name="username" value="&lt;?php echo $this-&gt;validation->username;?&gt;" /></p><br />
  
      <p>Password
      &lt;input type="password" name="password_2" value="&lt;? echo $this-&gt;validation->password_2;?&gt;" /></p>
      <br />
      &lt;input type="submit" name="submit" value="submit" /&gt;&lt;/p>
    &lt;/form&gt;

my controller -

Code:

function form()
        {
      $this->load->helper(array('form','url'));
      $this->load->library('validation');
      
      $rules['username']="trim|required|xss_clean";
      $rules['password_2']="trim|required|xss_clean";
      
      $this->validation->set_rules($rules);
      
      $fields['username']='username';
      $fields['password_2']='password_2';
      
      $this->validation->set_fields($fields);
      
      if($this->validation->run()==FALSE)
      {
        $this->load->view('adminLoginView');
      }
      else
      {
        $this->load->view('admin');
      }
    }

Thanks,

In u'r VIEW file use this...

Code:

<?php echo validation_errors(); ?>

instead of this
<?php echo $this->validation->error_string; ?>

You should be using the new form validation library.

As of CI 1.7.0 the validation library has been deprecated!

CI 2.0 the validation library has been removed!

Changed the view and still getting an error -

Call to undefined method CI_Loader::validation_errors()

What is the new validation library? I am using 1.7.2. Is the user manual wrong? I am now totally lost.

Do I just set up a html form and in the controller use the if(isset) coding?

Take a look at the Form Validation Class library in
the Users Guide

Code:

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

// View
<?php echo validation_errors(); ?>
