Question

我正在尝试创建一个PHP文件来将图像上传到我的网站。我有以下代码，但它无法正常工作。任何人都可以帮我修复它，所以我没有得到任何错误？有没有更好的方法来做这样的事情？我知道这是老式的。

    $uploaddir = "uploads/images";
    $allowed_ext = "jpg, JPG, png, gif";
    $max_size = "500000";
    $max_height = "4000";
    $max_width = "4000";

    $extension = pathinfo ($_FILES['file']['name']);
    $extension = $extension[extension];
    $allowed_paths = explode(", ", $allowed_ext);
    for ($i = 0; $i <= count($allowed_paths); $i++){
            if ($allowed_paths[$i] == "$extension"){
            $ok = "1";
        }
    }
    if ($ok == "1"){
        if($_FILES['file']['size'] > $max_size){
                print "Your file is too big!";
                exit;
            }
        }

    if($max_width && $max_height){
        list($width, $height, $type, $w) = getimagesize($_FILES['file']['name']);
        if ($width > $max_width || $height > $max_height){
                print "Your file width/height are too big!";
                exit;
            }

        }
    if (is_uploaded_file($_FILES['file']['tmp_name'])){
        move_uploaded_file($_FILES['file']['tmp_name'], $uploaddir.'/'.$_FILES['file']['name']);

        print "Your file was uploaded successfully :)";
        }
                else
                    print "Wrong extensin";



    ?>

当我运行脚本时，我收到以下错误：

Warning: getimagesize(1 (8).jpg) [function.getimagesize]: failed to open stream: No such file or directory in D:\Hosting\8923686\html\uploadedimages\upload.php on line 25

Warning: move_uploaded_file(uploads/images/1 (8).jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in D:\Hosting\8923686\html\uploadedimages\upload.php on line 33

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'D:\Temp\php\phpE5F5.tmp' to 'uploads/images/1 (8).jpg' in D:\Hosting\8923686\html\uploadedimages\upload.php on line 33

或

invalid file

任何人都可以告诉我我的问题在哪里？

Answer 1

对于第一个错误，请将getimagesize($_FILES['file']['name'])更改为getimagesize($_FILES['file']['tmp_name'])。

至于其他两个错误，请确保您的脚本有权将文件写入您尝试将上传文件移动到的文件夹。

修改：还尝试在$uploaddir中使用完整的绝对路径，而不仅仅是uploads/images。由于您使用的是不在文档根目录中的脚本的相对路径，因此PHP可能会查找错误的目录。

Answer 2

第25行中的

getimagesize($_FILES['file']['name']是第一个罪魁祸首：你的意思是getimagesize($_FILES['file']['tmp_name']

对于其他错误，您需要检查uploads/images的权限 - 它们显然是对网络服务器用户的限制。
