Codeigniter 2.1 - fileupload You did not select a file to upload - php

Question

Model function:
public function file_upload($folder, $allowed_type, $max_size = 0, $max_width = 0, $max_height = 0)
{
$folder = $this->path . $folder;
$files = array();
$count = 0;
foreach ($_FILES as $key => $value) :
$file_name = is_array($value['name']) ? $value['name'][$count] : $value['name'];
$file_name = $this->global_functions->char_replace($file_name, '_');
$count++;
$config = array(
'allowed_types' => $allowed_type,
'upload_path' => $folder,
'file_name' => $file_name,
'max_size' => $max_size,
'max_width' => $max_width,
'max_height' => $max_height,
'remove_spaces' => TRUE
);
$this->load->library('image_lib');
$this->image_lib->clear();
$this->load->library('upload');
$this->upload->initialize($config);
if (!$this->upload->do_upload($key)) :
$error = array('error' => $this->upload->display_errors());
var_dump($error);
return FALSE;
else :
$file = $this->upload->data();
$files[] = $file['file_name'];
endif;
endforeach;
if(empty($files)):
return FALSE;
else:
return implode(',', $files);
endif;
}
This function is working partially. Files are being uploaded to the selected folder, but I am getting this error: You did not select a file to upload. and getting FALSE as a result? What seems to be a problem? (form is using form_open_multipart)

Answer 1

Please make sure that you have this name of your file tag field:
$key='userfile' //which is name of input type field name

Answer 2

Are any of your file inputs empty when this happens? $_FILES will contain an array of "empty" data if there is no file specified for the input. For example, my file input name is one, and I submitted it without specifying a file:
Array
(
[one] => Array
(
[name] =>
[type] =>
[tmp_name] =>
[error] => 4
[size] => 0
)
)
You should check if the file data is empty before processing the upload. PHP's is_uploaded_file() is useful for this.
