Form attached to Codeigniter

Question

Good afternoon.

I had to implement a section for sending resumes through the site, but the attachment is not working, even the script can read $_FILES even having in the form the attribute * enctype="Multipart/form-data"*, it is always empty. What can it be?

Form (view):

<form action="<?php echo base_url(lang())?>/trabalhe-conosco/enviar" method="post" class="formulario-contato fonte-padrao-titulos" enctype="multipart/form-data">
    <div class="col col-30 fl">
        <label class="opacity">Hidden</label>
        <div class="clearfix file-box">
            <div class="fake-input"><?php echo set_value('userfile')?></div>
            <label class="file-button-send <?php echo (form_error('userfile')) ? 'error' : '' ?>" for="userfile">
                ANEXAR CURRÍCULO
                <input class="hide<?php echo (form_error('userfile')) ? ' error' : '' ?>" type="file" name="userfile" id="userfile">
            </label>
            <?php echo form_error('userfile') ?>
        </div>
    </div>
    <div class="col col-20 fr">
        <label class="opacity">Hidden</label>
        <input class="fonte-padrao-titulos black" type="submit" value="<?php echo $this->lang->line('botao_form'); ?>">
    </div>
</form>
