Multiple file upload scripts have stopped working - php

I have a site with multiple file uploaders on it, all of which have stopped working.
I am getting no errors; it's like the PHP just refuses to acknowledge the $_FILES handler.
This only occurs on the live server; on my local development system the exact same files work fine.
The HTML I use is:
<input type="file" name="docfile">
The PHP is:
if ($_FILES['docfile']['name'] != '') {
if (!file_exists('upld/documents/'.$docid)) {
mkdir('upld/documents/'.$docid, 0777, true);
}
//sanitise filename
$cleanname = preg_replace('/\s+/', '-', $_FILES['docfile']['name']);
$upfile = "v0-" . $cleanname;
//Upload image
$temp = $_FILES['docfile']['tmp_name'];
$dest = "upld/documents/".$docid."/";
if(move_uploaded_file($temp,$dest.$upfile))
{
//save file name in DB MySQL stuff here
} else {
$errors[] = "There was an error while uploading file";
}
}
Could a change on the server have affected this?

It turned out that someone had run an update on the server which had reset the php.ini setting file_uploads to OFF.
Once I changed it back to ON everything worked again.

PHP SSH move file to another directory [duplicate]

I am uploading files to a server using php and while the move_uploaded_file function returns no errors, the file is not in the destination folder. As you can see I am using the exact path from root, and the files being uploaded are lower than the max size.
$target = "/data/array1/users/ultimate/public_html/Uploads/2010/";
//Write the info to the bioHold xml file.
$xml = new DOMDocument();
$xml->load('bioHold.xml');
$xml->formatOutput = true;
$root = $xml->firstChild;
$player = $xml->createElement("player");
$image = $xml->createElement("image");
$image->setAttribute("loc", $target.basename($_FILES['image']['name']));
$player->appendChild($image);
$name = $xml->createElement("name", $_POST['name']);
$player->appendChild($name);
$number = $xml->createElement("number", $_POST['number']);
$player->appendChild($number);
$ghettoYear = $xml->createElement("ghettoYear", $_POST['ghetto']);
$player->appendChild($ghettoYear);
$schoolYear = $xml->createElement("schoolYear", $_POST['school']);
$player->appendChild($schoolYear);
$bio = $xml->createElement("bio", $_POST['bio']);
$player->appendChild($bio);
$root->appendChild($player);
$xml->save("bioHold.xml");
//Save the image to the server.
$target = $target.basename($_FILES['image']['name']);
if(is_uploaded_file($_FILES['image']['tmp_name']))
echo 'It is a file <br />';
if(!(move_uploaded_file($_FILES['image']['tmp_name'], $target))) {
echo $_FILES['image']['error']."<br />";
}
else {
echo $_FILES['image']['error']."<br />";
echo $target;
}
Any help is appreciated.

Most like this is a permissions issue. I'm going to assume you don't have any kind of direct shell access to check this stuff directly, so here's how to do it from within the script:
Check if the $target directory exists:
$target = '/data/etc....';
if (!is_dir($target)) {
die("Directory $target is not a directory");
}
Check if it's writeable:
if (!is_writable($target)) {
die("Directory $target is not writeable");
}
Check if the full target filename exists/is writable - maybe it exists but can't be overwritten:
$target = $target . basename($_FILES['image']['name']);
if (!is_writeable($target)) {
die("File $target isn't writeable");
}
Beyond that:
if(!(move_uploaded_file($_FILES['image']['tmp_name'], $target))) {
echo $_FILES['image']['error']."<br />";
}
Echoing out the error parameter here is of no use, it refers purely to the upload process. If the file was uploaded correctly, but could not be moved, this will still only echo out a 0 (e.g. the UPLOAD_ERR_OK constant). The proper way of checking for errors goes something like this:
if ($_FILES['images']['error'] === UPLOAD_ERR_OK) {
// file was properly uploaded
if (!is_uploaded_File(...)) {
die("Something done goofed - not uploaded file");
}
if (!move_uploaded_file(...)) {
echo "Couldn't move file, possible diagnostic information:"
print_r(error_get_last());
die();
}
} else {
die("Upload failed with error {$_FILES['images']['error']}");
}
You need to make sure that whoever is hosting your pages has the settings configured to allow you to upload and move files. Most will disable these functions as it's a sercurity risk.
Just email them and ask whether they are enabled.
Hope this helps.
your calls to is_uploaded_file and move_uploaded_file vary. for is_uploaded_file you are checking the 'name' and for move_uploaded_file you are passing in 'tmp_name'. try changing your call to move_uploaded_file to use 'name'

Uploading files using php very slow in xampp

I am new for developing.I have opted for php to learn coding.So I might make mistake as I learn by myself, kindly clarify my doubts.
I have problem in uploading files using php to a folder.What I really do is, I upload a file and the file is saved in a folder and the name of the file alone inserted in the database. While uploading the file I do copy the file to another folder which will be used for the editing purpose so that the original file will not be disturbed.Here the problem I get is, the file is uploaded successfully as well as the name too inserted in database. But it take much time to get upload even the size of the file is small.It works good while I test using my local but when I come in real time this issue(slow uploading) I face. What the person incharge in uploading do is, uploading a file and opening a new browser and upload another file. When the new browser is opened the files get uploaded but in the previous browser it is still in process. The code I have written to copy the file to another folder is not executed as the new browser is opened to upload another set of files. I am using xamp cp v3.2.1.To minimize the execution time I have set the default Maximum execution time to 30. But unable to upload file fastly.
Below is my php coding:
<?php
// connect to the database
include('connect-db.php');
if (isset($_POST['submit']))
{
// get form data, making sure it is valid
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
$file_array=($_FILES['file_array']['name']);
// check to make sure both fields are entered
if ($udate == '' || $file_array=='')
{
// generate error message
$error = 'ERROR: Please fill in all required fields!';
// if either field is blank, display the form again
renderForm($udate, $file_array, $error);
}
else
{
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
if(isset($_FILES['file_array']))
{
$name_arrray=$_FILES['file_array']['name'];
$tmp_name_arrray=$_FILES['file_array']['tmp_name'];
for($i=0;$i <count($tmp_name_arrray); $i++)
{
if(move_uploaded_file($tmp_name_arrray[$i],"test_uploads/".str_replace(' ','',$name_arrray[$i])))
{
// save the data to the database
$j=str_replace(' ','',$name_arrray[$i]);
echo $j;
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
$provider = mysql_real_escape_string(htmlspecialchars($_POST['provider']));
$existfile=mysql_query("select ubatch_file from batches");
while($existing = mysql_fetch_array( $existfile)) {
if($j==$existing['ubatch_file'])
echo' <script>
function myFunction() {
alert("file already exists");
}
</script>';
}
mysql_query("INSERT IGNORE batches SET udate='$udate', ubatch_file='$j',provider='$provider',privilege='$_SESSION[PRIVILEGE]'")
or die(mysql_error());
echo $name_arrray[$i]."uploaded completed"."<br>";
$src = 'test_uploads';
$dst = 'copy_test_uploads';
$files = glob("test_uploads/*.*");
foreach($files as $file){
$file_to_go = str_replace($src,$dst,$file);
copy($file, $file_to_go);
/* echo "<script type=\"text/javascript\">
alert(\"CSV File has been successfully Uploaded.\");
window.location = \"uploadbatches1.php\"
</script>";*/
}
} else
{
echo "move_uploaded_file function failed for".$name_array[$i]."<br>";
}
}
}
// once saved, redirect back to the view page
header("Location:uploadbatches1.php");
}
}
?>
It takes much time because, each and everytime all the files are copied to the newfolder. This exceeds the execution time.Only copying the uploaded files makes uploading and copying files fast.

uploading binary file to server

I'm converting an image to a binary file in IOS, which works just fine. This will be handled by my php script which is suppose to upload this image to my ubuntu server. The problem is i keep getting file=unsuccessful. i've tried different directory paths, but cant seem to solve this issue.
This $directory will return this: /var/www/User/core/ios/
<?
if(!empty($_POST))
{
$message = $_POST['message'];
$directory = $_SERVER['DOCUMENT_ROOT'] . '/User/core/ios/';
$file = basename($_FILES['userfle']['upload']);
$uploadfile = $directory . $file;
var_dump($_FILES);
$randomPhotoID = md5(rand() * time());
echo 'file='.$file;
echo $file;
if (move_uploaded_file($_FILES['userfle']['tmp_name'], $uploadfile)) {
echo 'successful';
}
else
{
echo 'unsuccessful';
}
}
else
{
echo('Empty post data');
}
?>
Check the error file of your php(you can make sure if you enabled the error log in php.ini),
if you don't have the permission or for some other reasons it can't move the file ,there will be a record in that file.
Some time you can try the command setenforce 0 if you confirm you(I means the user of apache) have the permission to move the file but it not work.
By the way if the file you want to move is not upload by post, there is no error log and the move function will return false.

PHP upload form doesn't accept .pdf

For some reason, my PHP-upload field doesn't accept pdf-files. I don't get it cause I thought there is no selection made while uploading the file... Any advice?
$name = $_FILES["uploadedfile"]["name"];
$tmp_name = $_FILES["uploadedfile"]["tmp_name"];
$add = "downloads/lkverslagen/".$name;
move_uploaded_file($tmp_name, $add);
if(file_exists("downloads/lkverslagen/$name")) {
$lkverslag = new LKverslag();
$jaar = date (Y);
$lkverslag->titel = $titel;
$lkverslag->datum = $datecorrect;
$lkverslag->link = $name;
$lkverslag->jaar = $jaar;
$lkverslag->auteur = $_SESSION['user']['naam'];
$lkverslag->teller = $_POST['titel'];
if ($lkverslag->saveverslag($_DB)) {
$feedback = "OK";
} else {
$feedback = "NOT OK";
}
} else {
$feedback = "ERROR";
}
Here are some things to check:
Ensure that your file upload and post limits are not reached by editing upload_max_filesize and post_max_size in your .htaccess or php.ini file. If you have error reporting on, you should see an error when they're reached. See this: http://drupal.org/node/97193
Check for file upload error codes. See the documentation for these: http://www.php.net/manual/en/features.file-upload.errors.php
Ensure that your memory_limit has not been reached. Again, with error logging enabled, you should receive an error message about this. http://drupal.org/node/207036
Check PHP's common pitfalls documentation and make sure there's nothing there that helps: http://www.php.net/manual/en/features.file-upload.common-pitfalls.php
If none of this helps, enable error reporting and post what you receive so we can tailor our answers better to your situation.
So, to repeat my comment: there are limits on the allowed size of uploaded files -- the PDF file might simply be too large.

problem with uploading the images with php file upload

hi guys i am uploading the images using the #PhP file upload Method # If i upload 10 Images at a time (Each Images is 2000 /3000 dimension). then the on click save function is not working. if i upload 5 images or less than five images then its working fine wats wrong with my coding i just include my php code with this post <input value="Save" type="submit" name="SubSave" id="SubSave" onClick="return changes();">
if($_POST['SubSave'] == "Save"){
$aid = $_GET['rid'];
$updcount = $_POST['theValue'];
if($_SESSION["almgtype"]==1 || (GetUserNoPhoto($_SESSION["almgid"]))>(GetTotalPhotoCount1($_SESSION["almgid"],$aid))) {
$uid = $_SESSION["almgid"];
for($k=1;$k<=$updcount;$k++) {
//echo $k;
echo $_FILES["uploadfile"]["type"];
if($_FILES["uploadfile".$k]["name"]!="") {
if(($_FILES["uploadfile".$k]["type"] == "image/gif") || ($_FILES["uploadfile".$k]["type"] == "image/jpeg")|| ($_FILES["uploadfile".$k]["type"] == "image/pjpeg") || ($_FILES["uploadfile".$k]["type"] == "image/png")) {

You probably need to change the maximum POST size in your php.ini configuration file (post_max_size setting).
You can use the command phpinfo() to dump your configuration. Likely, as others have stated you need to increase the upload size and execution time.
These can be modified through a .htaccess file.
php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200
Just as a warning: Your upload handling script will make it utterly trivial to completely subvert your server:
You blindly trust that the $_FILES[...]['type'] value is correctly set - this value is completely under the user's control, and they can stuff in "image/jpeg" and upload any type of file they want
You blindly trust that the $_FILES[...]['filename'] value is correctly set - again, this value is completely under the user's control, and they can stuff in "hackme.php" if they want to
You blindly write the file to your photoalbum directory, but don't check if the user-supplied filename contains pathing data
So, what happens if someone uploads the following file:
$_FILES['uploadfile0']['type'] = 'image/gif';
$_FILES['uploadfile0']['filename'] = '../pwn_me.php';
You've now happily put a user-provided PHP script ONTO YOUR WEBSERVER and they can now do anything they want.
On top of that, your database queries blindly insert the same data into the queries, leaving you wide open to SQL injection attacks. As well, you don't check for filename collisions until AFTER you've moved the file. So, someone could upload a malicious script, but only do it once for that particular filename. Congratulations, you've implemented versioned attacks on your server. You'll have "pwn_me.php", "pwn_me2.php", "pwn_me3.php", "my_little_pwnme.php", and so on.
