Library Upload not working
#1

(This post was last modified: 02-13-2017, 08:21 PM by ciadmin. Edit Reason: Fixed the glaring RED )

I have a form to upload an image, but in the controller when I load the library upload and use do_upload () or display_errors (), I get the following message:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Grupos::$upload
Filename: admin/grupos.php
Line Number: 66



Fatal error: Call to a member function do_upload() on null in C:\xampp\htdocs\pilloti\application\controllers\admin\grupos.php on line 66

It would be better if you can post the controller, view and model code.

When I put $ this-> load-> library ('upload'); It does not give me any errors, but when I use something from the library itself.

The first character of the filename should be upper case.

Load the form helper in the controller before you load the form:
PHP Code:
$this->load->helper('form'); 

Then, in your view, open the form with:
PHP Code:
<?php echo form_open_multipart('admin/grupos/guardarGrupo','id="frmNuevoGrupo"');?>

Without multipart, you won't be able to handle upload files.
