如何在会话中上传多个文件？

Question

I am trying to upload multiple images at once within sessions. In my case the user must upload the exact amount of images he stated earlier for one "position" and repeat the action for another "position" with different images againg with the correct amount. Unforunately the upload doesn't work and I don't know why. Should I use $_POST instead of $_FILES, or is the foreach method not correct? Here is the code:

HTML:

<?php

session_start();
include('php/uploadspec.php');
if(!isset($_SESSION['face'][$_SESSION['counter']])){
    header("Location: cuberender.php");
}

$speccount = 1;

?>

<div class="counter">

        <form method="post">
            <div class="form-group">
                <p>Please Choose all <?php echo  $_SESSION['quantity'] ?> photos for <?php echo $_SESSION['face'][$_SESSION['counter']] ?></p>
            </div>
            <div class="form-group">
                <input type="file" name="images[]" accept="image/*" multiple />
            </div>
            <div class="form-group">
                <input type="submit" name="Submit" value="Submit!" />
            </div>
        </form>

        <?php
        if (isset($_POST['Submit'])) {
            $imgamount=count($_POST['images']);
            if ($imgamount==$_SESSION['quantity']){
            uploadspec(session_id(), $speccount);
            $_SESSION['counter']++;
            header("Location: posteditor.php");
            }
        }
        ?>

PHP:

    function uploadspec($id, $speccount){
    foreach($_FILES["images"]["tmp_name"] as $image) {
        $target_file = $id . '/' .$_SESSION['face'][$_SESSION['counter']]. '/specimage'.$speccount;
        $speccount++;
        move_uploaded_file($image, $target_file);
    }
}

Thanks in advance!

Please check php max upload limit & php max Post limit.
