Can not upload pdf, jpg file at different server - php

Can not upload PDF, JPG,... file at databases at different server?
I have a form on a one server and when they fill the data, data should be stored in a database on another server
function do_upload_files($id) {
$allowed_doc_exts = "txt|pdf|jpg|jpeg|doc|odt|gif";
$allowed_docs = 5;
$ret = array();
for ($i = "0"; $i <= $allowed_docs; $i++) {
$exts = explode("|", $allowed_doc_exts);
$doc = "documents_" . $i;
if (!isset($_FILES[$doc]))
continue;
if (empty($_FILES[$doc]["name"]))
continue;
$ext = pathinfo($_FILES[$doc]["name"], PATHINFO_EXTENSION);
if (!in_array(strtolower($ext), $exts))
continue;
$doc_dir = "/home/httpd/vhosts/domain.com/httpdocs/content/document/$id/";
if (!is_dir($doc_dir))
mkdir($doc_dir, 0777, true);
$doc_path = $doc_dir . $i;
if(move_uploaded_file($_FILES[$doc]["tmp_name"], $doc_path)) {
$ret[$i]["name"] = $_FILES[$doc]["name"];
$ret[$i]["type"] = $_FILES[$doc]["type"];
}
This is problem (i think):
$doc_dir = "/home/httpd/vhosts/domain.com/httpdocs/content/document/$id/";

You have to create some kind of API, on the server you wanna put files on. Otherwise you could just easily put files on stackoverflow server for example. So you have to create an API on the other server, who takes the files, and saves it onto the server. Aswell, you should password protect it, or you will be hacked very fast, if everybody can put files on your server.
On the other side, you just have to send data with a form, which contains the files.

Upload fails "move uploaded file"

First off, the upload folder is given 777, and my old upload script works, so the server accepts files. How ever this is a new destination.
I use krajee bootstrap upload to send the files. And I receive a Jason response. The error seems to be around move uploaded file. I bet it's a simple error from my side, but I can't see it.
<?php
if (empty($_FILES['filer42'])) {
echo json_encode(['error'=>'No files found for upload.']);
// or you can throw an exception
return; // terminate
}
// get the files posted
$images = $_FILES['filer42'];
// a flag to see if everything is ok
$success = null;
// file paths to store
$paths= [];
// get file names
$filenames = $images['name'];
// loop and process files
for($i=0; $i < count($filenames); $i++){
$ext = explode('.', basename($filenames[$i]));
$target = "uploads" . DIRECTORY_SEPARATOR . md5(uniqid()) . "." . array_pop($ext);
if(move_uploaded_file($_FILES["filer42"]["tmp_name"][$i], $target)) {
$success = true;
$paths[] = $target;
} else {
$success = false;
break;
}
}
// check and process based on successful status
if ($success === true) {.
$output = [];
$output = ['uploaded' => $paths];
} elseif ($success === false) {
$output = ['error'=>'Error while uploading images. Contact the system administrator'];
// delete any uploaded files
foreach ($paths as $file) {
unlink($file);
}
} else {
$output = ['error'=>'No files were processed.'];
}
// return a json encoded response for plugin to process successfully
echo json_encode($output);
?>
I think field name is the issue. Because you are getting image name with filer42 and upload time, you are using pictures.
Please change
$_FILES["pictures"]["tmp_name"][$i]
to
$_FILES["filer42"]["tmp_name"][$i]
And check now, Hope it will work. Let me know if you still get issue.
The error is not in this script but in the post.
I was using <input id="filer42" name="filer42" type="file">
but it have to be <input id="filer42" name="filer42[]" type="file" multiple>
as the script seems to need an arrey.
It works just fine now.

uploaded file is too big php

Hi i have the following code that uploads videos to a server and updates the database accordingly. This code works fine when i run it with a bunch of images and or small video's. See the code below:
for ($i=0; $i<count($_FILES['images']['error']); $i++) {
if ($_FILES['images']['error'][$i] == UPLOAD_ERR_OK) {
$tmpName = $_FILES['images']['tmp_name'][$i];
$name = $_FILES['images']['name'][$i];
$type = $_FILES['images']['type'][$i];
if (strpos($type, 'image') !== false) {
$type = "img";
}elseif(strpos($type, 'video') !== false){
$type = "vid";
}else{
exit();
}
move_uploaded_file(($tmpName), $dir.$name);
$upload = array(
'name'=>$name,
'type'=>$type
);
$uploads[] = $upload;
}
}
But when my client tries to upload a video bigger than 64mb the program doesnt upload it... I already tried to change the max_file_size and other according parameters to allow bigger files. But my clients hosting provider doesnt allow this.
So are there any other ways of uploading big files to my server via my custom cms?

So as said in comments. Reference material is below code examples. Trick is to cut the file into chunks that are less than the upload limit. This method can be extended to the point that when a file upload is interrupted you can continu on the last known part. :-)
Basic JavaScript class to assist in uploading the file, determines the chunks to be sent to a PHP server.
function fileUploader() {
// Called when the file is selected
this.onFileSelected = function() {
// Read file input (input type="file")
this.file = this.fileInput.files[0];
this.file_size = this.file.size;
this.chunk_size = (1024 * 1000);
this.range_start = 0;
this.range_end = this.chunk_size;
this.slice_method = 'slice';
this.request = new XMLHttpRequest();
// Start uploading
this.upload();
};
this.upload = function()
{
var self = this,
chunk;
// Last part reached
if (this.range_end > this.file_size) {
this.range_end = this.file_size;
}
// Chunk the file using the slice method
chunk = this.file[this.slice_method](this.range_start, this.range_end);
// Open a XMLHttpRequest
var endpoint = "/url/to/php/server/for/processing";
this.request.open('PUT', (endpoint));
this.request.overrideMimeType('application/octet-stream');
this.request.send(chunk);
// Make sure we do it synchronously to prevent data corruption
this.request.onreadystatechange = function()
{
if (self.request.readyState == XMLHttpRequest.DONE && self.request.status == 200) {
self.onChunkComplete();
}
}
};
this.onChunkComplete = function()
{
if (this.range_end === this.file_size)
{
// We are done, stop uploading
return;
}
this.range_start = this.range_end;
this.range_end = this.range_start + this.chunk_size;
this.upload();
};
}
And for the PHP bit:
...
$out = fopen("{$filePath}.partial", "a+");
fwrite($out, file_get_contents("php://input"));
fclose($out);
...
Big warning here, make sure to properly validate and take security measures to ensure the safety of your clients upload function. You are writing the raw PHP input to a file.
When the upload is done you can rename the file to it's original name including the correct extension.
Reference material:
http://creativejs.com/tutorials/advanced-uploading-techniques-part-1/index.html
https://secure.php.net/manual/en/wrappers.php.php
In a nutshell.. it's break the file into small chunks using a processor, upload the files using conventional methods (like you would normally upload a file), append the input to a temporarily file. Some pitfalls I encountered were sending extra params and alike to the endpoint, avoid those as it's appended to the file and it will corrupt your file.

machine path of the file uploaded in drupal 7

I am editing a current website right now. I want to change file uploading mechanism from http to ftp. They use File module with Drupal 7. the thing i need is, in a form, when i select which files to upload, how can i get their machine path (e.g. C:\path/to/file.mov)?
I need this path to use in php ftp_nb_put function.
function assets_managed_file_form_upload_submit($form, &$form_state) {
for ($i = 0; $i < $form_state['num_files']; $i++) {
if ($form_state['values']['files_fieldset']['managed_field'][$i] != 0) {
// Make the file permanent.
$file = file_load($form_state['values']['files_fieldset']['managed_field'][$i]);
$file->status = FILE_STATUS_PERMANENT;
$directory = 'private://cubbyhouse/'. $form_state['values']['allowed_user'];
file_prepare_directory($directory, FILE_CREATE_DIRECTORY);
$file->uri = file_unmanaged_copy($file->uri, $directory, FILE_EXISTS_REPLACE);
$file->uid = $form_state['values']['allowed_user'];
drupal_chmod($file->uri);
file_save($file);
//drupal_set_message(t($debug=print_r($form)));
// Need to add an entry in the file_usage table.
file_usage_add($file, 'assets', 'image', 1);
drupal_set_message(t("Your file has been uploaded!"));
}
}
}
Right now this is how they handle file submitting

Does tmp_name disappear after move_uploaded_file is used?

I have this page where you can send message to multiple people and attach files into it...
Here is my code
<?php
session_start();
$inboxfrom = $_SESSION['loginusername'];
$inboxto = $_POST['inboxto'];
$inboxsubject = $_POST['inboxsubject'];
$inboxcontent = $_POST['inboxcontent'];
$inboxtime = date('g:i A', time()+(6*60*60));
$inboxdate = date('Y-m-d', time()+(6*60*60));
mysql_connect("127.0.0.1", "root", "")or die("Cannot Connect toDb");
mysql_select_db("Abbot_db");
$count = 0;
function generateRandomString($length = 8){
$string = "";
$possible = "0123456789bcdfghjkmnpqrstvwxyz"; //character that can be used
for($i=0;$i < $length;$i++){
$char = substr($possible, rand(0, strlen($possible)-1), 1);
if (!strstr($string, $char)){
$string .= $char;
}
}
return $string;
}
if (count($inboxto) != 0){
$count = 0;
while ($count < count($inboxto)){
$recepient = $_POST['inboxto'][$count];
mysql_query("INSERT INTO Inbox_tbl(InboxTo, InboxFrom, InboxSubject, InboxContent, InboxTime, InboxDate,InboxStatus,ToDelete,FromDelete)VALUES ('$recepient','$inboxfrom','$inboxsubject','$inboxcontent','$inboxtime','$inboxdate','Unread','No','No')");
$recepient_result = mysql_query("SELECT * FROM Accounts_tbl WHERE UserID='$recepient'");
if (mysql_result($recepient_result, 0, "UserTypeID") == 1){
$notiurl = "LMSadmin_inbox.php";
} else if (mysql_result($recepient_result, 0, "UserTypeID") == 2) {
$notiurl = "LMSteacher_inbox.php";
} else {
$notiurl = "LMSstud_inbox.php";
}
mysql_query("INSERT INTO Noti_tbl(NotiTo,NotiFrom,NotiContent,NotiDate,NotiTime,NotiType,NotiUrl)
VALUES('$recepient','$inboxfrom','has sent you a message','$inboxdate','$inboxtime','Message','$notiurl')");
//---------------------------------------------------------
$countto = 0;
$cont = generateRandomString(128);
$folder = "./Attachments/".$cont;
$name = $_FILES['file']['name'];
if (!empty($name)){
while (is_dir($folder)){
$cont = generateRandomString(128);
$folder = "./Attachments/".$cont;
}
mkdir($folder, 0700, true);
}
while ($countto < count($_FILES['file']['name'])){
$name = $_FILES['file']['name'][$countto];
$type = $_FILES['file']['type'][$countto];
$tmp_name = $_FILES['file']['tmp_name'][$countto];
$folder = "Attachments/".$cont."/";
move_uploaded_file($tmp_name, $folder.$name);
$fileurl = $cont."/".$name;
$dummypost = mysql_query("SELECT * FROM Inbox_tbl ORDER BY InboxID DESC");
$msgid = mysql_result($dummypost, 0, "InboxID");
mysql_query("INSERT INTO Attachments_tbl(FileUrl,FileName,AttachType,AttachID)
VALUES('$fileurl','$name','Message',$msgid)");
$countto++;
}
//----------------------------------------------
$count++;
}
}
header('Location: ' . $_SERVER['HTTP_REFERER']);
?>
now the result after I put multiple recepients and multiples is that... The first recepient will get the attachments.. meaning the folder of attachment will be randomy generated and the files would be put in there.... but on the next recepient the attachments would not be moved on their respective folder.. I can see the folder have been made but the files arent moved..
MY question is.. does the "temp_name" disappear after you use the "move_uploaded_file" code? Because I think thats is the reason the files arent not move.. Is so can you suggest any alternate code i can use?
move_uploaded_file() relocates the file to the set target location with rendering the tmp_name useless afterwards.
What you should do is to create a "puffer" folder where you originally move the uploaded file, and then call copy() as many times as you need to deliver the file to the recipient folders. When the file is put to every needed location, you can unlink() the file from this puffer folder.
Alternatively, you might put the file to only one location (to eliminate redundancy and overuse of storage space), and make links in your Attachments_tbl to this same file in a set attachments folder. However, this needs remodelling of how your system works to make sure that the (now one and only) attachment file is only removed after every record pointing to it is removed also.
Yes, the file is moved, this is why you can't find it. I suggest that you:
Move the inner while loop (the one for the uploaded files) before the first while loop (for the recipients), and move the uploaded files to a location that you specify
Create a new inner while loop that copies the files from the location you specified earlier to each user's attachments folder

How to compare two file structures in PHP?

I have a function which gives me the complete file structure upto n-level,
function getDirectory($path = '.', $ignore = '') {
$dirTree = array ();
$dirTreeTemp = array ();
$ignore[] = '.';
$ignore[] = '..';
$dh = #opendir($path);
while (false !== ($file = readdir($dh))) {
if (!in_array($file, $ignore)) {
if (!is_dir("$path/$file")) {
//display of file and directory name with their modification time
$stat = stat("$path/$file");
$statdir = stat("$path");
$dirTree["$path"][] = $file. " === ".
date('Y-m-d H:i:s', $stat['mtime']) . " Directory ==
".$path."===". date('Y-m-d H:i:s', $statdir['mtime']) ;
} else {
$dirTreeTemp = getDirectory("$path/$file", $ignore);
if (is_array($dirTreeTemp))$dirTree =
array_merge($dirTree, $dirTreeTemp);
}
}
}
closedir($dh);
return $dirTree;
}
$ignore = array('.htaccess', 'error_log', 'cgi-bin', 'php.ini', '.ftpquota');
//function call
$dirTree = getDirectory('.', $ignore);
//file structure array print
print_r($dirTree);
Now here my requirement is , I have two sites
The Development/Test Site- where i do
testing of all the changes
The Production Site- where I finally
post all the changes as per test in
development site
Now, for example, I have tested an image upload in the Development/test site, and i found it appropriate to publish on Production site then i will completely transfer the Development/Test DB detail to Production DB, but now I want to compare the files structure as well to transfer the corresponding image file to Production folder.
There could be the situation when I update the image by editing the image and upload it with same name, now in this case the image file would be already present there, which will restrict the use of "file_exist" logic, so for these type of situations....HOW CAN I COMPARE THE TWO FILE STRUCTURE TO GET THE SYNCHRONIZATION DONE AS PER REQUIREMENT??
EDITED
the requirement has to be a script, which I am going to need as a joomla component functionality.. please reply as per this.
I would suggest using rsync for this.
