trying to upload multiple files
Move_uploaded_file not working.
file permission user#777
$file = $_FILES['photo'];
$count = count($file['name']);
for($a = 0 ; $a<$count ; $a++)
{
echo $_FILES['photo']['name'][$a];
$target_dir = preg_replace('/\s+/',
'',$name.'_'.basename($_FILES['photo']['name'][$a]));
$target_file = "../upload/".$target_dir;
echo $target_file;
if(move_uploaded_file($_FILES['photo']["name"][$a], $target_file))
{
echo 'yes';
}
else
{
echo 'no';
}
}
You maybe pointing to the wrong path. Make it complete by using $_SERVER['DOCUMENT_ROOT'].
This:
$target_file = "../upload/".$target_dir;
to:
$target_file = $_SERVER['DOCUMENT_ROOT']."/upload/".$target_dir;
The source file should be 'tmp_name' one, not the 'name'.
From:
if(move_uploaded_file($_FILES['photo']["name"][$a], $target_file)){
To:
if(move_uploaded_file($_FILES['photo']["tmp_name"][$a], $target_file)){
If the above changes still don't fix it:
Check your php.ini
;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;
; Whether to allow HTTP file uploads.
file_uploads = On
; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
;upload_tmp_dir =
; Maximum allowed size for uploaded files.
upload_max_filesize = 50M
; Maximum number of files that can be uploaded via a single request
max_file_uploads = 20

I'm a PHP newbie and have written a script to process form uploads. It works for small files(less than 1Mb). However when I try to upload an ~4Mb pdf file it returns an error message. What am I doing wrong?
PS: I ran php_info, got the value of "upload_tmp_dir" and set it to a directory owned by the apache process(www-data)
My client-side code is
<form action="upper.php" method="post" enctype="multipart/form-data">
<input type="file" name="myFile"><br>
<input type="submit" value="Upload">
</form>
Upper.php contains
define("UPLOAD_DIR", "/var/www/html/upload/");
if (!empty($_FILES["myFile"])) {
$myFile = $_FILES["myFile"];
if ($myFile["error"] !== UPLOAD_ERR_OK) {
echo "Error is " . $myFile["error"];
//echo "<p>An error occurred.</p>";
exit;
}
$name = preg_replace("/[^A-Z0-9._-]/i", "_", $myFile["name"]);
// don't overwrite an existing file
$i = 0;
$parts = pathinfo($name);
while (file_exists(UPLOAD_DIR . $name)) {
$i++;
$name = $parts["filename"] . "-" . $i . "." . $parts["extension"];
}
// preserve file from temporary directory
$success = move_uploaded_file($myFile["tmp_name"], UPLOAD_DIR . $name);
if (!$success) {
echo "<p>Unable to save file.</p>";
exit;
}
// set proper permissions on the new file
chmod(UPLOAD_DIR . $name, 0644);
}
Most probably you have wrong config in you php.ini file.
You need to set
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
its already described here: PHP change the maximum upload file size
You ned to set values in php.in file.
Open the file,
Find upload_max_filesize and post_max_size lines.
Change this two value. (M= MB)
; Maximum allowed size for uploaded files.
upload_max_filesize = 20M
; Must be greater than or equal to upload_max_filesize
post_max_size = 20M
Restart the sever for effect.
Note:
You can set any number. But not use any decimal value.
Open the php.ini file in NOTEPAD. Don't user wordpad or any word processor.
I want to upload files from my server. I had written this piece of code months ago when it worked fine, but now I have no idea what's going wrong.
I basically want to move the file to a folder "uploads" in my server and then store the path in the database.
The uploaded file doesn't get reflected in the database.
if(isset($_POST['submit']))
{
require("dbconn.php");
$filename = $_POST['filename'];
$name = $filename . "." . pathinfo($_FILES['ufile']['name'],PATHINFO_EXTENSION);
//$name = $_FILES['ufile']['name'];
//$size = $_FILES['file']['size']
//$type = $_FILES['file']['type']
$tmp_name = $_FILES['ufile']['name']; //was tmp_name
$error = $_FILES['ufile']['error'];
if(isset($name))
{
if(!empty($name))
{
$location = 'uploads/';
if(move_uploaded_file($tmp_name, $location.$name))
{
echo "hi";
$filename = $_POST['filename'];
$filepath = $location.$name;
$advname = $_POST['advname'];
$year = $_POST['year'];
$cname = $_POST['cname'];
$ctype = $_POST['ctype'];
$sqlq = "INSERT INTO file(filename, filepath, advname, year, cname, ctype) VALUES ('".$filename."','".$filepath."','".$advname."','".$year."','".$cname."','".$ctype."');";
$result = mysql_query($sqlq);
if(!$result)
{
die("Error in connecting to database!");
}
}
}
}
}
There seems to be a problem in the
if(move_uploaded_file($tmp_name, $location.$name))
statement. This condition is evaluated as false.
If $_FILES['ufile']['error'] gives you a value of 1 then the upload_max_filesize in your config is set to a smaller value that the file you are trying to upload.
You cannot change the upload_max_filesize from within your code.
If you have access to your php.ini, .htaccess, httpd.conf or .user.ini you can change this value in any of those files.
So you would need to add or modify the parameter from its default of 2M (2meg)
upload_max_filesize = 20M
Its also a good idea to check the post_max_size at the same time as this may also have an effect on the max size of the file uploaded, make sure post_max_size is larger than upload_max_filesize as this should allow extra space for the other fields that you will be uploading as part of the post
I'm using this code to upload folder files.
<form action="file_transfer.php" method="post" enctype="multipart/form-data" name="form1">
<input type="file" name="file_input[]" id="file_input" multiple="" webkitdirectory="">
<input type='submit' class='btn' id='btn_upload_file' value='UPLOAD' data-loading-text='loading....'/>
</form>
And file_transfer.php
$uploads_dir = 'C:/xampp/htdocs/awoc_inspection/Images/IMAGES/';
for($i = 0; $i < sizeof($_FILES['file_input']['name']); $i++){
$tmp_name = $_FILES['file_input']['tmp_name'][$i];
$name = $_FILES['file_input']['name'][$i];
echo $_FILES['file_input']['tmp_name'][$i];
echo $_FILES['file_input']['name'][$i];
echo"<br/>";
move_uploaded_file($tmp_name, "$uploads_dir/$name");
}
It does not show any error but when I go to C:/xampp/htdocs/awoc_inspection/Images/IMAGES/
folder there is no image. I don't know why this code can't move uploaded folder files please help me :(
It doesnt print error cause you didnt ask it to do:
echo $_FILES["file"]["error"][$i];
The problem might be that your directory doesnt have good permission try chmod 775 or 777
Also do:
echo $result = move_uploaded_file($tmp_name, "$uploads_dir/$name");
to check whether $result is true or false, if false then moving file wasnt done
Try to change the for condition with:
for($i = 0; $i < sizeof($_FILES['file_input']); $i++) {
...
I've overcome own my problem :) .. thank's everyone for your answers ... the only problem why I can't upload pictures it is because the picture that I'm trying to upload is 3mb above and the maximum upload file_size in php is 2mb .
I've changed php.ini to
;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 50M
$image = $_FILES['picture']['name'];
$id=$_SESSION['id'];
//This function separates the extension from the rest of the file name and returns it
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
$ext = findexts ($_FILES['picture']['name']) ;
//This assigns the subdirectory you want to save into... make sure it exists!
$target = "mainimage/";
//This combines the directory, the random file name, and the extension
$target = $target . $id.".".$ext;
if(move_uploaded_file($_FILES['picture']['tmp_name'], $target))
{
echo ("This is your new profile picture!");
}
else
{
echo "Sorry, there was a problem uploading your file.";
}
for some reason the "else" keeps showing up (there was a problem uploading the file). I put comments in everything that I am trying to do. please help! thanks!
To close the question as per OP's request.
The issue is that you need to increase the maximum size for uploads. PHP's default is usually 2M and you are most probably trying to upload a file larger than what the maximum setting is set to.
This can be achieved in two ways.
By editing your php.ini file with the following settings:
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
or via an .htaccess file placed in the root of your server:
php_value upload_max_filesize 20M
php_value post_max_size 30M
here is the code that i use to upload files and unzip them in a directory.
But the problem is that it seems to be very slow on files greater than 5MB.
I think it doesnt have to do with the network because it is in localhost computer.
Do I need to edit any parameter in php.ini file or apache or any other workarround?
$target_path = "../somepath/";
$target_path .= JRequest::getVar('uploadedDirectory')."/";
$target_Main_path= JRequest::getVar('uploadedDirectory')."/";
$folderName = $_FILES['uploadedfile']['name'];
$target_path = $target_path . basename($folderName);
//upload file
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path."/")) {
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
$zip = new ZipArchive;
$res = $zip->open($target_path);
$target_path = str_replace(".zip", "", $target_path);
echo $target_path;
if ($res === TRUE) {
$zip->extractTo($target_path."/");
$zip->close();
echo "ok";
} else {
echo "failed";
}
When handling file uploads ther are a lot of factors to consider. These include PHP settings:
max_input_time
max_execution_time
upload_max_filesize
post_max_size
Execution time can affect the upload if for example, you have a slow upload speed resulting in a timeout.
File size can cause problems if the upload is larger than the upload_max_filesize like wise if your file size + the rest of the post data exceeds post_max_size.
Zip uses a lot of memory in the archive/extraction processes and could easily exceed the memory allocated to PHP -so that would be worth checking as well.
I would start with this page and note some of the comments.
