Hi,
I give a piece of code that can be usefull for some people that will want to take the time understanding the function. It upload files coming from a multiple upload form and if all ok return a files array, other wise delete the uploaded files from server.
It’s sure far from perfect and I release it as is, it’s part of an application I have developped, so if you are interrested about use this function, you must of course adapt it for your application.
Also note that I will answer basic questions about it, but I won’t give any other kind of support for this.
function multiple_upload($upload_dir = 'uploads', $config = array())
{
$CI =& get_instance();
$files = array();
if(empty($config))
{
$config['upload_path'] = realpath($upload_dir);
$config['allowed_types'] = 'gif|jpg|jpeg|jpe|png';
$config['max_size'] = '2048';
}
$CI->load->library('upload', $config);
$errors = FALSE;
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
if( ! $CI->upload->do_upload($key))
{
$data['upload_message'] = $CI->upload->display_errors(ERR_OPEN, ERR_CLOSE); // ERR_OPEN and ERR_CLOSE are error delimiters defined in a config file
$CI->load->vars($data);
$errors = TRUE;
}
else
{
// Build a file array from all uploaded files
$files[] = $CI->upload->data();
}
}
}
// There was errors, we have to delete the uploaded files
if($errors)
{
foreach($files as $key => $file)
{
@unlink($file['full_path']);
}
}
elseif(empty($files) AND empty($data['upload_message']))
{
$CI->lang->load('upload');
$data['upload_message'] = ERR_OPEN.$CI->lang->line('upload_no_file_selected').ERR_CLOSE;
$CI->load->vars($data);
}
else
{
return $files;
}
}
Sample usage:
if( ! $files = $this->upload->multiple_upload('public/photos'))
{
echo 'Something went wrong during upload';
}
else
{
echo 'Upload success !<br />';
echo '<pre>';
print_r($files);
echo '</pre>';
}
