I am trying to validate a form in codeigniter and I have not been able to achieve it. I would like to validate the variables that arrive from the input of the form mailcontacto.php that is in view and that in that form show me the validation errors. The form sent well until you try to place the validation. Below the codes.

<?php

defined('BASEPATH') OR exit('No direct script access allowed');
class Emails extends CI_Controller {
function index(){
$datos['contenido'] = 'emails';
$this->load->view('contacto/mailcontacto', $datos); 
}
function enviar() {
//Descargar la libreria
$this->load->library('email');
$this->load->library('form_validation');


        $nombre = $this->input->post('nombre');
        $telefono = $this->input->post('telefono');
        $email = $this->input->post('email');
        $asunto = $this->input->post('asunto');
        $mensaje = $this->input->post('mensaje');
        $body_msg =  '<html><body><br />'.

Look, assuming you have set the .htacces to remove the index.php

we have the view

<form action="emails/enviar" method="post">
  <table style="width:80%; margin-left:12%">
    <tbody>
      <tr>
        <td>
          <table style="width:70%; margin-left:16%; margin-right:16%;">
            <tbody>
              <tr>
                <td><label><a >Nombre:</a></label></td>
              </tr>
              <tr>
                <td>
                  <?= form_error('nambre');?>
