Only upload if user set a value - El Forum - 10-10-2010

Hi,
I'm doing a file upload, and I needed it to only upload if the user has set a value to the image.
I tried using
Code:
if ($this->input->post('logo'))
{
$config['upload_path'] = './images/CarLogo';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '180';
$config['max_height'] = '180';
$config['overwrite'] = 'TRUE';
$this->load->library('upload', $config);
if(!$this->upload->do_upload('logo'))
{
$this->upload->display_errors();
exit();
}
$logo = $this->upload->data();
if ($logo['file_name'])
{
$logo = $logo['file_name'];
$this->MManage->updatelogo($logo);
}
}but if you do an echo on the $this->input->post('logo');
you'll realize that it is always blank whether user sets it or not.
What's wrong with my code?
Thanks

Does using isset work?
Code:
if (isset($this->input->post('logo')))-tg

You want to check if a FILE was selected so you have to check
the file array - for example:
Code:
<?php
if (isset($_FILES['logo']['name']) AND strlen($_FILES['logo']['name'])>0){
// upload here
}

Thanks, $_FILES works.
