I am able to upload a zip file and compress it, now i need the filename alone... but when i try to reach the name i get along with zip.
asas.text = "upload/" +fileRef.name + "/" +as.text;
Also How can i point the current viewing URL before the upload path.. something if
http://www.yahoo.com/upload/filename/ If the file is viewed from yahoo domain
Use the basename function.
$fileName = basename('/path/to/file.zip'); // $fileName == 'file.zip';
I think you're asking for the server name? Using your example above:
echo $_SERVER['SERVER_NAME']; // prints "www.yahoo.com"

I am having a problem with move_uploaded_file().
I am trying to upload a image path to a database, which is working perfectly and everything is being uploaded and stored into the database correctly.
However, for some reason the move_uploaded_file is not working at all, it does not produce the file in the directory where I want it to, in fact it doesn't produce any file at all.
The file uploaded in the form has a name of leftfileToUpload and this is the current code I am using.
$filetemp = $_FILES['leftfileToUpload']['tmp_name'];
$filename = $_FILES['leftfileToUpload']['name'];
$filetype = $_FILES['leftfileToUpload']['type'];
$filepath = "business-ads/".$filename;
This is the code for moving the uploaded file.
move_uploaded_file($filetemp, $filepath);
Thanks in advance
Try this
$target_dir = "business-ads/";
$filepath = $target_dir . basename($_FILES["leftfileToUpload"]["name"]);
move_uploaded_file($_FILES["leftfileToUpload"]["tmp_name"], $filepath)
Reference - click here
Try using the real path to the directory you wish to upload to.
For instance "/var/www/html/website/business-ads/".$filename
Also make sure the web server has write access to the folder.
You need to check following details :
1) Check your directory "business-ads" exist or not.
2) Check your directory "business-ads" has permission to write files.
You need to give permission to write in that folder.
make sure that your given path is correct in respect to your current file path.
you may use.
if (is_dir("business-ads"))
{
move_uploaded_file($filetemp, $filepath);
} else {
die('directory not found.');
}
Ok here is my code for uploading files
$ext_whitelist = array('pdf','doc','doc','mkv','mp4','mpg','mpeg','avi','flv','wma','ogg');
if(in_array($ext, $ext_whitelist))
{
$uniqid_file = uniqid('', true)."_".$file['name'];
$lokacija = $folder . "/" . $uniqid_file;
$encoded_uniqid_file = base64_encode($uniqid_file);
move_uploaded_file($file['tmp_name'], $lokacija);
$base_url= base_url("forms/fdownload/$encoded_uniqid_file/$path");
$form_data[$key] = "$uniqid_file ";
}
This checks file extension, so easy some could rename file, can someone help me to check file type proper?
Insted of a comment, I'll write a bit more as an answer.
Mimetype checking is a good thing if you want to know the type of the file, but it's not secure if you want to allow/deny the files at upload, because it's very easy to fake the mimetype.
Just try it, you can change it with a proxy or you can create a simple image, then add some php code at the end and rename it to .php. If you only check the mimetype, you can upload this .php file and run it on the server.
If you upload .jpg with php code in it, it's okay, the server won't push it through the php parser. (Except when you change the default configuration. (Apache: AddType, nginx: AddHandler )
There are some "secure" ways to check the uploaded files:
1. Check the extension and compare it to a whitelist.
This is the example in the question, but I'd like to write a complete solution. (A common mistake to check only the first think after the ., because there could be file names like: something.txt.php so always check the last postfix.)
$ext = array_pop(explode(".", $fileName));
$whitelist = array('pdf','doc','doc','mkv','mp4','mpg','mpeg','avi','flv','wma','ogg');
if (in_array($ext, $whitelist) {
//OK the extension is good, handle the upload.
} else {
//Wrong type, add error message.
}
If you use something like this, be careful and never allow extensions like .php and anything wich is in the server config.
2. Rename the file and drop the extension.
This is an another good way, but maybe you want to keep the original file name, the extension and the mimetype. You can store them in a database!
For this solution just take the original filename, add some random data (because if you upload into a single folder and you trie to upload something.jpg 2 time that would be a bad idea), then store this.
For example:
$newName = sha1($fileName.time());
move_uploaded_file($file['tmp_name'], $uploadPath . $newName);
Because the file doesn't have an extension, the server wont try to run it. (But if it's for example an image it'll work in the browsers, because they use the mimetype to determine the type and we didn't changed that.)
You can use
perl-file-mimeinfo
Ex:-
$file_path = '/tmp/temp.jpg';
$mimetype = trim(shell_exec("/usr/bin/mimetype -bi ".escapeshellarg($file_path)));
$info = null;
if(strpos($mimetype, "video/")===0 || strpos($mimetype, 'x-flash-video') > 0){
$info = 'video';
}elseif(strpos($mimetype, "audio/")===0){
$info = 'audio';
}elseif(strpos($mimetype, "image/")===0){
$info = 'image';
}
So I have an upload service with many people uploading the same files to my Amazon S3 bucket. I changed my app design so the SHA1 of the file is calculated upon upload and checked against the list of uploaded files.
If it exists, I simply assign the file to the new uploader as well.
The problem with this is, the file being named as the first uploader named it. All subsequent uploaders will get the same first name.
I can use download="" attribute in HTML5 but it doesn't work in IE:
http://caniuse.com/#search=download
The files are stored remotely so I can't change the header unless I download it first to my local server which is illogical.
Please advice.
The only way I see this possible is to add a meta-data just before redirecting user to download.
You can add meta-data to your files in S3. With key as "Content-Disposition" and value as 'attachment; filename="~actual file name~"'. You can force the name and trigger download.
This way, you don't have to download any files to local file system.
The caveat to this is if someone else is also requesting the same file with in milli-seconds, first user might get the name as requested by second user.
use the rename() method
example:
$file = "boo.png";
$newName = "scary";
$ext = substr( $file, strpos( "." ), strlen( $file ) );
$path = "/images/downloaded/";
rename($path . $file, $path . $newName . $ext);

I already looked at this StackOverflow question and it didn't help (similarly titled).
I'm passing an image in from my Android application. If I type
$file = fopen('test.jpg', 'wb');
It works correctly and the image uploads; however, I want to allow for multiple uploads from android phones, so I want to randomize the name of the .jpg file so that I can save each new upload as a different name. I was trying this below:
$destination = time() + rand(1, 1000) . ".jpg";
$url_destination = "/project_images/" . $destination;
$file = fopen($url_destination, 'wb');
fwrite($file, $binary);
fclose($file);
It doesn't write the file to the server, however. I tried different variations of the URL there - with 'project_images/', '/project_images/', even trying the full URL (which the aforementioned StackOverflow post corrected me on), and I still can't get it to write.
The permissions of the project_images folder are set to allow files to be written to it. Any ideas?
Your problem is "/project_images" which is a wrong absolute path.
For it to work change it to "project_images/" or dirname(__FILE__).'/project_images/'.
For those who use XAMPP on Windows: use DIRECTORY_SEPARATOR instead /
dirname(__FILE__).DIRECTORY_SEPARATOR.'project_images'.DIRECTORY_SEPARATOR
I've been looking at various PHP/AJAX file upload plugins online, but I'm having some trouble finding one feature I really need. For the purposes of this upload, each file that I upload must go into a directory with the same name as that file (minus the extension). Naturally, the nicest way would be to create that folder during the upload and then send the file to it. I know this involves mkdir() in some way, and I've found a number of scripts that even perform basic folder creation, but I'm not clear on how to do this dynamically using the filename. Any ideas?
Thanks!
When you upload a file in php it is stored in the $_FILES array, its name is stored in $_FILES['inputfield']['name'] where 'inputfield' is the name in the file input like:
<input type='file' name='inputfield' />
So then you would do:
$exp = explode(".",$_FILES['inputfield']['name']);
$filename = $exp[0];
$path = "/path/to/base/folder/" . $filename . "/" . $_FILES['inputfield']['name'];
move_uploaded_file($_FILES['inputfield']['tmp_name'], $path);
$fileName = $_FILES['fieldname']['name']
$foldername = substr($fileName, 0, strrpos($fileName, '.'));
