Answer 1

input type='file' POST you file in $_FILES
SO instead of this
if(isset($_POST['images']) && !empty($_POST['images']))
You have to check your condition as
if (!empty($_FILES['images']['name'])) {
$filetmp = $_FILES["images"]["tmp_name"];
$filename = $_FILES["images"]["name"];
$filetype = $_FILES["images"]["type"];
$filepath = "photo2/" . $filename;
move_uploaded_file($filetmp, $filepath);
}
