variable global

You can do this by setting the table name as a property of that class:

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class M_lideres extends CI_model {

protected $table_name = "lideres";

 /*
 * Recupero todos os lideres da tabela.
 * Se for passado o parâmetro ID do lider, então recupero somente um lider
 */
 function exibe_dados($limite, $offset) {

 $this -> db -> limit($limite, $offset);
 $count = $this -> db -> get($this->table_name);
 return $count -> result();

 } 


Then change your table references as above to:

PHP Code:

$this->table_name
