public function savepost() {
if(isset($this->request->data['multifiles'])){
$file_name_all="";
for($i=0; $i<count($this->request->data['multifiles']); $i++){
if(!empty($this->request->data['multifiles'][$i]['name'])){
$file = $this->request->data['multifiles'][$i];
$file['name'] = time() . '-' . str_replace(' ', '_', $file['name']);
$uploadPath = WWW_ROOT . 'img/ ';
$fileName = $file['name'];
$uploadFile = $uploadPath.$fileName;
$file_name_all.= $file['name'].",";
if($file['name']){
move_uploaded_file($file['tmp_name'], $uploadFile);
}
}
}
}
}
in my code it is working.
