问题 I have a html form that allows image uploads, but the image uploaded now fails the "is_uploaded_file" check for some reason. So why does the upload fail the is_uploaded_file check?

问题 I have seen a lot of upload forms hacked, and some had some really good security checks of the file being uploaded (at least I think so), but still somebody managed to upload a PHP file.

So first here's my html: <form action="upload_file.php" method="post" enctype="multipart/form-data"> Select a file: <input type="file" name="img"> <input type="submit"> </form> And here's my php: $allowedExts = array("doc", "docx"); $extension = end(explode(".", $_FILES["file"]["name"])); if ($extension!=".doc" || $extension!=".doc" && ($_FILES["file"]["size"] < 200000) && in_array($extension, $allowedExts)) { if ($_FILES["file"][

问题 plupload creates nice ids in file object. How this id can be sent to the upload script? The upload script has 3 variables in $_POST - file name, chunk number and total number of chunks.

Then, if you are using multipart, you can change the uploader settings to dynamically set different multipart params: plupload_instance.bind('BeforeUpload'

问题 In order to upload a binary file to an URL, I have been advised to use this guide. However, the file is not in a directory, but is stored in a BLOB field in MySql db. The BLOB field is mapped as a byte[] property in JPA: byte[] binaryFile; I have slightly modified the code taken from the guide, in this way: HttpURLConnection connection = (HttpURLConnection ) new URL(url).openConnection(); // set some connection properties OutputStream output = connection.getOutputStream(); PrintWriter writer
