我正在尝试创建一个脚本，允许用户向我们提供信息并上传3张图像到数据库，以显示他们所面临的问题的证据。
我使用了一个我在网上找到的脚本，并修改了它来处理我的表单。图片没有被上传，因为我得到错误'对不起，只有JPG, JPEG, PNG &;GIF文件是允许的。，如下面的代码所示。我上传的图片肯定是。jpg，所以我不明白为什么会发生这种情况?

if(isset($_POST['submitForm'])) {
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];

$question_2 = $_POST['question2'];
$question_3 = $_POST['question3'];
$question_4 = $_POST['question4'];
$question_5 = $_POST['question5'];
$image_1 = $_POST['fileToUpload1'];
$image_2 = $_POST['fileToUpload2'];
$image_3 = $_POST['fileToUpload3'];
$message = $_POST['message'];
$target_dir = "/var/www/vhosts/system/removed.co.uk/etc/contact-facility/uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
$uploadOk = 1;
}

$uploadOk = 0;

if (file_exists($target_file)) {
$uploadOk = 0;

echo "Sorry, your file is too large.";
$uploadOk = 0;

echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;

$dbname = "removed";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO contact_facility (first_name, last_name, email_address, hospital_trust, question_1, question_2, question_3, question_4, question_5, image_1, image_2, image_3, message) VALUES ('$firstname', '$lastname', '$email', '$organisation', '$question_1', '$question_2', '$question_3', '$question_4', '$question_5', '$image_1', '$image_2', '$image_3', '$message')";

我不明白为什么这些图像是A:不上传和B:在文件扩展名上显示错误，而我上传的图像显然是。jpg。
我哪里做错了，你会如何解决这个问题?
