My problem here is even though it gets saved "successfully" the file is not actually saved. (I'm running this on the Cloud9IDE)

My folder exports is set to be readable and writable via chmod 777 -R ./.

Can someone explain to me why the hello.txt file is not being created, and what I can do to solve this problem?


$("[data-action=save-file]").on("click", function(e) {
  var filename = "hello.txt"
  var content = "Hello world!"

    type: "GET",
    url: "submit.php",
    data: {
      "filename": filename,
      "content": content,
    cache: false,
    success: function(msg) {
    error: function(XMLHttpRequest, textStatus, errorThrown) {
      console.log("Some error occurred")


  $filename = $_GET["filename"];
  $fp = fopen("anon/".$filename, "wb");
  if (!$fp) {
    echo getcwd();
  } else {
    $outputstring = $_GET["outputstring"];
    fwrite($fp, $outputstring);

I've also tried...

  $filename = $_GET["filename"];
  $outputstring = $_GET["outputstring"];
  file_put_contents($filename, $outputstring, FILE_APPEND | LOCK_EX);

    If this is the actual code that is posted, then the arguments being sent by ajax are "content" and "filename", while php is expecting "outputstring" and "filename", so, on the php end, there is no "outputstring" and the program doesn't check for "content" in $_GET.

    $filename = $_GET["filename"];
    $outputstring = $_GET["content"];
    file_put_contents($filename, $outputstring, FILE_APPEND | LOCK_EX);

    Also there is a max length to too url parameters for GET (Max size of URL parameters in _GET), so if file content is ever an actual file this may be truncated. Try using type: "POST" instead.

    wb is not any mode in php. use w+ instead of wb

    and you need to check folder is exist or not

       $path = "anon";
       if (!file_exists($path) && is_dir($path))
            if (!mkdir($path, 0777, TRUE))
                return false;

    The code in php $fp.close() is error. It should be fclose($fp).

    maybe you should start debugging server side: first of all, when using file_put_contents, check if it returns false (use operator ===). In this case folder anon/ doesn't exists. second: check for writability of that folder with is_writable.

    if (!isset($_GET[...], $_GET[...])) die("missing vars...");
    if (!is_writable($filenamewithpath)) die("dir not writable");
    if (file_put_contents(...) === false) die("dir doesn't exists");

    if directory not writable, try using chmod($path, 0777). could be that your main directory is 0777 but not the sub-directories.

    by the way, as others pointed out, your ajax call is sending "content", not "outputstring" as parameter. you should rename the data object key.

    try also to use absolute path (using for example __DIR__ . "/anon/". $filename);
