I have seen that codeigniter does not allow you to upload .xlsm files
'allowed_types' => "gif|jpg|jpeg|png|iso|dmg|zip|rar|doc|docx|xls|xlsx|ppt|pptx|csv|ods|odt|odp|pdf|rtf|sxc|sxi|txt|exe|avi|mpeg|mp3|mp4|3gp"
but I have this situation and I need to upload an .xlsm file. what do you recommend me?
When the user click on "Insertar Nuevo Calendario (upload XLSM file)", the user will select a file and it will automatically be stored always in the same folder "./download", if it exists it will be overwritten and if it does not exist it will create it again.
plantilla_view.php
<li class="nav-item dropdown">
<a class="nav-item nav-link dropdown-toggle mr-md-2" href="#" id="btncalendarios" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<i class="fas fa-calendar-alt"></i>
</a>
<div class="dropdown-menu dropdown-menu-right" aria-labelledby="bd-versions2">
<a class="dropdown-item" href=" " >
<i class="fas fa-calendar-plus"></i> Insertar Nuevo Calendario (upload XLSM file)
</a>
<?php foreach($calendarios['calendario'] as $calendario) { ?>
<a class="dropdown-item" href="<?php echo base_url(); ?>Descargar/?nombre_fichero=<?php echo $calendario; ?> " >
<i class="fas fa-calendar-alt"></i> <?php echo $calendario; ?>
</a>
<?php } ?>
</div>
</li>
