Bir dosya aktarıcı yazı olmuştur ve ben türleri ve boyutunu doğrulamak istiyorum, ve ben şu anda bu var:

    <?php 

//SETTING UP LOCAL VARIABLES
$username = trim($_POST['username']);
$password = trim($_POST['password']);
$name = trim($_POST['name']);
$email = trim($_POST['email']);
$message = trim($_POST['message']);

//STRIPPED OUT ALL NON ASCII CHARACTERS
$username = preg_replace('/[^(\x20-\x7F)]*/','', $username);
$password = preg_replace('/[^(\x20-\x7F)]*/','', $password);
$name = preg_replace('/[^(\x20-\x7F)]*/','', $name);
//$email = preg_replace('/[^(\x20-\x7F)]*/','', $email);

//SETTING UPLOAD DIR
$upload_dir = $_SERVER['DOCUMENT_ROOT'] . "/beta_images/";

//CREATING A RANDOM HASH TO PROTECT FROM DUPLICATE FILES
$random = rand(1, 100);

$user_hash = $random . $name;

$hash = sha1($user_hash);
$hash = substr($hash, 32, $random);

foreach ($_FILES['file']['error'] as $key => $error) {

$counter++;

if (
(
    ($_FILES['file']['type'][$key] == "image/jpeg")
 || ($_FILES['file']['type'][$key] == "image/pjpeg")
 || ($file['file']['type'][$key] == "image/jpg")
)

&& ($error == UPLOAD_ERR_OK)
&& ($_FILES['file']['size'][$key] < 20971520)
) {

        $temp_name = $_FILES['file']['tmp_name'][$key];
        $image_name = $hash . '_' . $name . $counter . '.jpg';
        move_uploaded_file($temp_name, $upload_dir . $image_name);

    } else {

    $body_fail = "Someone forgot to do something and wound up on the Sorry page. You might want to contact them and try and convince them to join still. Here are the details \n\n Username: $username \n Password: $password \n Email: $email \n Name: $name \n Message: $message";

    mail("bla", "Failed beta sign up", $body_fail);

    header("Location: ../sorry.html");

    }

}

        //EMAIL INTERNAL

            $body_internal = "Success! $name has submitted a beta entry!\n\n Their username is \n $username \n Their password is \n $password \n Their email address is $email.\n\n The images are located in \n /beta_images/{$hash}_{$name}1/2/3.jpg \n\n They also wrote a little message for us: \n$message";

            mail("bla", "New Beta Sign Up", $body_internal);

        //EMAIL INTERNAL

        //EMAIL EXTERNAL

            $body_external = "Thank you for applying to join the Stylistic Gallery, we just wanted to let you know that we have received everything and will be in touch shortly.\n\n Best Wishes \n Stylistic Gallery \n\n The Stylistic Gallery, a portal for creative individuals and businesses to showcase and sell their work online";

            mail($email, "Thank you for your application", $body_external);

        //EMAIL EXTERNAL

        header("Location: ../thanks.html");

Dosyaları jpg değilse veya boyutu daha büyük olsa bile Ancak yine de geçiyor.

Şu anda çok uzun ona bakarak çok karışık, muğlak olduğu için özür dilerim :)

Teşekkürler!
