Major form validation error messaging troubles

Code:

&lt;?php

    

    echo form_open('auth/validate_credentials_login');

    echo "<span class='errors_login'>";

    echo form_error('email_login');

    echo "</span>";

    echo form_label('','Email', 'email_login');

    $data = array( 'name' => 'email', 'class' => 'input', 'placeholder' => 'Email');

    echo form_input($data, set_value('email_login'));

    echo "<span class='errors_login'>";

    echo form_error('password_login');

    echo "</span>";

    echo form_label('', 'Password', 'password_login');

    $data = array( 'name' => 'password_login', 'class' => 'input', 'placeholder' => 'Password');

    echo form_password($data, set_value('sha1(password_login)'));

    echo form_submit('submit_login', 'Login');

    echo form_close();

    

    ?&gt;

Code:

function validate_credentials_login()

  {

   // WHEN THE VIEW IS LOADED THIS FUNCTION IS CALLED AND LOADS MODEL AS WELL AS DEFINES THE SALT VARIABLE AND LOADS THE ENCRYPTING HELPER LIBRARY

   

   $this->load->library('encrypt');

   $this->load->helper('url');

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

   $this->form_validation->set_rules('email_login', 'Email', 'required|is_unique[users.email]');

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

   $this->load->library('session');

   $this->load->model('user_model', 'um');

   $login = $this->input->post('submit_login');

   

   

 

    if($login) {

    

    $user = $this->um->validate_home_login(array('email' => $this->input->post('email_login')));

    if( $user ) {



     // CHECK THE USER'S PASSWORD AGAINST THE ONE FROM THE LOGIN FORM

     if($user->password == $this->encrypt->sha1( $user->salt . $this->encrypt->sha1($this->input->post('password_login')))) {

      $this->session->set_userdata(array(

       'email' => $this->input->post('email_login')

      ));

      redirect('account/dashboard');

      exit;

     }

    }

   }

  

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

   $data['main_content'] = 'home/home_page';

   $this->load->view('includes/templates/home_page_template', $data);

  }
