[SOLVED] $_POST is getting only the last field

I'm starting now with Codeiginiter and for days I'm trying to fix this code. I have a lot of fields in my form: name, email, phone, message, etc, but $_POST only get the last field, Message.

View HOME.PHP

PHP Code:

<?php echo form_open('/home/cadastrar'); ?>
                <div class="row">
                    <div class="col-md-6">
                        <div class="form-group">

Controller HOME.PHP

PHP Code:

public function cadastrar() {
        $this->output->enable_profiler(TRUE);

        $this->load->library('form_validation');
        $this->form_validation->set_rules('name', 'Nome Completo', 'trim|required|min_length[6]|max_length[50]|xss_clean');
        $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
        $this->form_validation->set_rules('phone', 'Telefone Celular', 'trim|required');
        $this->form_validation->set_rules('cep', 'CEP', 'trim|required|min_length[8]|max_length[9]|xss_clean');
        $this->form_validation->set_rules('addr', 'Endereço', 'trim|required|min_length[6]|max_length[50]|xss_clean');
        $this->form_validation->set_rules('numr', 'Número / Complemento', 'trim|required|min_length[1]|max_length[50]|xss_clean');
        $this->form_validation->set_rules('bairro', 'Bairro', 'trim|required|min_length[3]|max_length[50]|xss_clean');
        $this->form_validation->set_rules('cidade', 'Cidade', 'trim|required|min_length[3]|max_length[50]|xss_clean');
        $this->form_validation->set_rules('estado', 'Estado', 'trim|required|min_length[2]|max_length[2]|xss_clean');
        
        $data['title'] = "Curso";
        
        if ($this->form_validation->run() === FALSE) {
            $data['msg'] = " Desculpe, não foi possível concluir a matrícula.";
            $this->load->view('templates/header', $data);
            $this->load->view('pages/home');
            $this->load->view('templates/footer');    
        } else {
            $data['msg'] = " Matrícula efetuada! Clique no botão abaixo para efetuar o pagamento.";
            $this->load->view('templates/header', $data);
            $this->load->view('templates/registered');
            $this->load->view('templates/footer');
        }
    } 


So, form_validation always return FALSE because I'm only receiving data from the textarea "message".
