Question

Hi I am new to Codeigniter but have hit a brick wall.

I am trying to see if a user already exists.

First I upload the data via a form to a controller which does its validation etc but breaks on only that issue. I managed to find where it breaks but cant fix it from there.

Prior to all this it querys the database finds there is in fact a match username and then reaches the snippet below

      $errors = $this->tank_auth->get_error_message(); 
      //find the correct error msg

      foreach ($errors as $k => $v) $data['errors'][$k] =$this->lang->line($v);        
      //loop and find etc

      $temp_mess = $data['errors'][$k]; 
      //stores relevant stuff in the string
    }
  }
//echo $temp_mess; it outputs to the html so i can see it "says user exists"
$data['temp_mess'] = $tempmess; /// put this into a array

$this->load->view('layout', $data); ///send 
    }
}

Now for the view, it then calls the layout view etc but alas there is no output

$username1 = array(
        'name'  => 'username1',
        'id'    => 'username1',
        'value' => set_value('username1'),
        'maxlength' => $this->config->item('username_max_length', 'tank_auth'),
        'size'  => 30,
    );

<?php echo form_open('register', $form_reg_id ); ?>

<fieldset>
<legend align="center">Sign up</legend>
    <?php echo form_label('Username', $username1['id']); ?>
    <?php echo form_input($username1); ?>
    <?php $tempmess; ?>
    <div class="error"><?php echo form_error($username1['name']); ?>
    <?php echo isset($errors[$username1['name']])?$errors[$username1['name']]:''; ?>
<?php echo form_close(); ?>
</fieldset>

Thanks for any help on this

also could some one explain this line please. (for a really dumb person)

<?php echo isset($errors[$username1['name']])?$errors[$username1['name']]:''; ?>

Tank_auth automatically returns an error when the username exists. Juste have to check the errors array.
