Overwrite one function in download class. - El Forum - 06-03-2010
[eluser]businessman332211[/eluser]
I just want to overwrite ONE function in the uploader class.
I have created a new file inside applications/library and it's
My_Upload.php.
I have added the following code to it:
I basically want to overwrite the original filetype check function and add that
ability to use * as a wildcard. For some reason when I do this however it's
not overwriting the function.
Any advice?
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Upload extends CI_Upload{
function My_Upload($props = array())
{
parent::CI_Upload($props);
}
/**
* Verify that the filetype is allowed
*
* @access public
* @return bool
*/
/*
Adjustments: I have overwritten the original is_allowed_filetype
function with the same function. The only modification is it adds
a feature to allow the * to be used for filetypes in order to bypass
the check.
*/
function is_allowed_filetype()
{
if (count($this->allowed_types) == 0 OR ! is_array($this->allowed_types))
{
$this->set_error('upload_no_file_types');
return FALSE;
}
// This was added. If the * is passed as a wildcard it bypasses this filetype check.
if ($this->allowed_types[0] == '*') return TRUE;
$image_types = array('gif', 'jpg', 'jpeg', 'png', 'jpe');
foreach ($this->allowed_types as $val)
{
$mime = $this->mimes_types(strtolower($val));
// Images get some additional checks
if (in_array($val, $image_types))
{
if (getimagesize($this->file_temp) === FALSE)
{
return FALSE;
}
}
if (is_array($mime))
{
if (in_array($this->file_type, $mime, TRUE))
{
return TRUE;
}
}
else
{
if ($mime == $this->file_type)
{
return TRUE;
}
}
}
return FALSE;
}
// --------------------------------------------------------------------

it needs to be name MY_Upload ... not My_Upload!
