On the internet I saw how to make a form to upload files, but now as I do to be saved in the folders of Odoo9. If the PHP file does not work in the folders of odoo
<div name="foto_a_subir" t-attf-class="form-group #{error and
'foto_a_subir' in error and 'has-error' or ''}">
<label class="col-md-3 col-sm-4 control-label"
for="foto_a_subir">Subir Foto</label>
<div class="col-md-7 col-sm-8">
<input type="file" class="form-control" name="foto_a_subir"
required="True" t-attf-value="#{foto_a_subir or ''}"/>
</div>
</div>
