多个图片上传

Question

请参阅下面的代码，我没有收到任何错误，此代码之前有效，我确实改变了一些事情，但我似乎无法找到问题。非常感谢任何帮助。

实际上，代码没有检查文件的格式，它没有检查大小，也没有将文件上传到目录。

if ($_FILES['company_photos_uplaod']['filesToUpload']) {

    $Photos = $_FILES['company_photos_uplaod']['name'];
    $tmp_n = $_FILES['company_photos_uplaod']['tmp_name'];
    $photo_size = $_FILES['company_photos_uplaod']['size'];
    $photo_ext = strtolower(pathinfo($Photos, PATHINFO_EXTENSION));
    $dir = 'images/'; // upload directory   


    foreach($_FILES['company_photos_uplaod']['filesToUpload'] as $file) {

        if ($photo_ext != "jpg" && $photo_ext != "png" && $photo_ext != "jpeg") {
            $response["message"] = 'photos_invalid_format';
            $errors++;
        }

        if ($photo_size > 500000) { //500 Kb max
            $response["message"] = 'photos_file_too_large';
            $errors++;
        }

        $new_photo_names = rand(1000, 1000000).
        ".".$photo_ext;

        if ($errors == "") {

            if (move_uploaded_file($tmp_n, $dir.$new_photo_names)) {
                // upload photos and move to directory folder
            } else {
                $response["message"] = 'photos_error';
                $errors++;
            }
        }

    }

}
