I need declare some functions with different variables, these variables will content information fetched of the appropiate model across your controller.
The problem start in the moment that I need call the variables in the view file, By default only show me the variables that is declared in the index function, and the another show a error "indefined variable" And if I call the function across of URL don't works the first "index", Just works I called in the URL.
Please some that can help me...

so I think your asking is how to return data from two different models from within the same controller, then load the data into the view.

Code:
$data1 = $this->your_model->get_some_data();

$data2 = $this->other_model->get_some_other_data();

$final_data = array($data1, $data2);

$this->load->view('your_view', $final_data);

or instead of $final_data.... below might work better.. I am sure there are several ways to get this done.

$data = array_merge($data1, $data2);

$this->load->view('your_view, $data);

Ok, I´m sorry if I don´t explain me of the better way.
Here I put a single example, The mine is a bit most hard.

If I need to make a page with Header, Body and Footer; And the controller will look like this:

Controller

Code:
function header()

{

   $data['header'] = "Here goes the Header content";

   $this->load->view('page', $data);

}

function body()

{

   $data1['body'] = "Here goes the body content";

   $this->load->view('page', $data1);

}

function footer()

{

   $data2['footer'] = "Here goes the footer content";

   $this->load->view('page', $data2);

}

So In the page file in the VIEWS I call that variables simply adding a php script with "echo $footer", "echo $header" and "echo $body".

My problem start when I try of add the three variables same time, I need use them in the same page.

I thought that were problem of Index.php and I´ve been trying of remove it but I don´t get it..

Many thanks to the people that interest in this post..

Code:
// Controller method

public function page()

{

 $data = array(

  'header' => 'Here goes the Header content',

  'body'   => 'Here goes the Body content',

  'footer' => 'Here goes the Footer content'

 );

 $this->load->view('template', $data);

}

// Template view (/application/views/template.php)

&lt;html&gt;

&lt;head&gt;...&lt;/head&gt;

&lt;body&gt;

 &lt;?php

  echo $header;

  echo $body;

  echo $footer;

 ?&gt;

&lt;/body&gt;

&lt;/html&gt;

Thanks "Skunkbad", Do you have the reason.

But I need to make each one functions with content brought of a functions of a model.
So.

Model

Code:
class user extends CI_Model

{

 function login($username, $password)

 {

 $this -> db -> select('*');

 $this -> db -> from('usuario');

 $this -> db -> where('username = ' . "'" . $username . "'");

 $this -> db -> where('password = ' . "'" . MD5($password) . "'");

 $this -> db -> limit(1);

 $query = $this -> db -> get();

 if($query -> num_rows() == 1)

 {

     return $query->result();

 }

  else

  {

   return false;

  }

 } 

 function content()

 {

  $query = $this->db->query('SELECT * FROM actas');

  foreach ($query->result_array() as $row)

  {

   echo $row['codigoagencia'];

   echo $row['nombreacta'];

   echo $row['rutaarchivo'];

   echo $row['descripcion'];

   echo $row['creadopor'];

   echo $row['modificadopor'];

   echo $row['fechadecreacion'];

   echo $row['fechademodificacion'];

  }

  return $query->fetch_assoc();

 }

}

I use the function login for to make a loggin acces to my website and works perfect, But now I need brought information of different tables of my DB. Is by this that I need make several functions with different information.

Now I need to get this content of differents tables, pass to my controller for to define some rules and finally may show it in my view page.

Yeah, because it works

Code:
// Controller method

public function page()

{

 $this->load->model('the_model');

 $data = array(

  'header' => $this->the_model->get_header(),

  'body'   => $this->the_model->get_body(),

  'footer' => $this->the_model->get_footer()

 );

 $this->load->view('template', $data);

}

// Model

class The_model extends CI_Model{

 public function get_header()

 {

  return 'Here goes the Header content';

 }

 public function get_body()

 {

  return 'Here goes the Body content';

 }

 public function get_footer()

 {

  return 'Here goes the Footer content';

 }

}

// Template view (/application/views/template.php)

&lt;html&gt;

&lt;head&gt;...&lt;/head&gt;

&lt;body&gt;

 &lt;?php

  echo $header;

  echo $body;

  echo $footer;

 ?&gt;

&lt;/body&gt;

&lt;/html&gt;

Yes, you can have more than one function in a controller, but codeigniter considers them to be routes unless they are protected or private.
