I was trying to upload a file which is 20MB in size. Now default form upload size is 8MB. When I upload such a file i get $_POST and $_FILE variables empty. Now I want to put a check on file size. If I get both these variables empty, how can I put such a check ?? Please give me suggestions
Barring any code errors, its most likely your 20MB exceeds your upload limit.
Change this permanently from your php.ini file.
Use
ini_set("upload_max_filesize", "30M");
to set your max upload size for that session only. And for POST
Use this
ini_set("post_max_size", "30M");
To check the sizes
echo ini_get("post_max_size") . "\n";
echo ini_get("upload_max_filesize");
No idea what you actually want. But you can probe the recieved content size using:
$_SERVER["CONTENT_LENGTH"]
This should tell how big the POST request body would have been. (The number might be higher than the actual received content, in case of an aborted upload.)
Checkout php://input, the allowed 8mb part of it should be there.
For example echo file_get_contents('php://input');
You can dynamically set your max file size for upload.
write down below statement in your upload function where you are trying to upload file.
this will enhance limit up to 50 MB
ini_set("upload_max_filesize", "50M");
If you want to check file variables, you can user alternative HTTP_POST_FILES
$theFileSize = $HTTP_POST_FILES['file']['size'];
Hope this may help you.
Thanks.
Use MAX_FILE_SIZE as a hidden input field, this will stop the user waiting if the file is larger than the limit and won't execute your code so the variables won't be empty...
The MAX_FILE_SIZE hidden field (measured in bytes) must precede the
file input field, and its value is the maximum filesize accepted by
PHP. This form element should always be used as it saves users the
trouble of waiting for a big file being transferred only to find that
it was too large and the transfer failed. Keep in mind: fooling this
setting on the browser side is quite easy, so never rely on files with
a greater size being blocked by this feature. It is merely a
convenience feature for users on the client side of the application.
The PHP settings (on the server side) for maximum-size, however,
cannot be fooled.

I use Laravel 5.4 and I try upload video file. Image file upload successfully.
$video = Request::file('video_file')) {
$fullName = 'videos/'.uniqid().time().'.'.$video->getClientOriginalExtension();
Storage::disk()->put($fullName, $video);
But it didn't work. When I try get information about file - size = 0
What I do wrong?
There’s a limit on the amount of data you can send in a POST request. If you exceed that limit, PHP will return zero as the size of the file.
Instead, you’ll need to upload the file in chunks. If you’re using something like Amazon Web Services, they have a JavaScript SDK that will handle multi-part uploads for you: http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#upload-property
Check out http://php.net/manual/en/ini.core.php#ini.post-max-size
PHP has a default max_post_size of 8mb I believe, anything larger than that will not go through. There is also a upload_max_filesize that you may want to check out. I'm not sure if increasing the limit is the correct answer here, as I'm not sure what complications that would bring. When we upload large Files we use blue imp's file uploader: https://github.com/blueimp/jQuery-File-Upload
It's pretty straight forward and automatically chunks the uploads for you.
I need to upload files from the front in my plugin. I got the success with it, but then now I have an issue during uploading larger file than 1.5 KB. Whenever I select file larger than 1.5 KB, i get error:
1298012500: Required argument "newRockupload" is not set for Rock\RockUpload\Controller\RockuploadController->create.
So i have put this code in initializeCreateAction() of controller to debug:
$arguments = $this->request->getArguments();
DebuggerUtility::var_dump($arguments);
exit;
So whenever i select file which has lower size than 1.5 KB, I get posted data successfully in controller:
And whenever i select larger file than 1.5 KB i am getting nothing like this:
I tried and surfed lot. Need Help..
As it mentioned in the comments, this is probably an issue with the URL you are trying to send.
The parameter is not there in the TYPO3, (maybe not even on the server side.) I guess something is wrong with your fluid form.
You should inspect your request.
You can check it in your browser / apache access log / even with a debugger in the TYPO3 code.
Probably you are trying to send the data of the file in the Request Header instead of the Request Body.
You have probably some characters already in your URL so a file > 1.5 kb exceeds the limit of around 2000 characters in the url.
See also here about the limit of the url:
What is the maximum length of a URL in different browsers?
I have a HTML Form which deals with uploading files.
I use the PHP variables $_FILES (name, type, error, size, tmp_name) to store the values in my database and also validate the uploaded file.
I do most validations fine by checking mime types and what not. However when it comes to checking the size of the document, after research I have heard that the user can easily modify the content of $_FILES["size"] and make a fake value inside there.
This is a problem for my website as i am planning on restricting certain users to 20MB upload and higher ranked members to uploading a max of 100mb, and so on...So of course it is problematic if a regular user tricks the code to saying the size is lower then 20mb, whereas the file could actually be over 20MB.
So the question is, how do i tackle this sittuation and check the file size properly?
Note, i cannot use getimagesize() since the files being uploaded are not images.
It's normal
everyone can change request headers
the user also could change $_FILES[*]['type'], so you have to be carefull about it
you have to use filesize() php function http://php.net/manual/en/function.filesize.php
<?php
echo filesize($_FILES['myFile']['tmp_name']);
?>
hope help you
try using the filesize function php,
for instance
<?php
$filename = $_FILES['File']['tmp_name'];
echo $filename . ': ' . filesize($filename) . ' bytes';
?>
Read the documentation in php manual filesize
I know there are many questions about Request Entity Too Large on internet but i could not find right answer for my problem ;)
I`m using HTML file input tag to let users upload their images .
<input type = 'file' class = 'upload-pic' accept='image/*' id ='Fuploader' name = 'pro-pic'><br>
There is nothing wrong with files less than 2 MB which is allowed by my site
But the problem is if some one decide to upload larger file like 5.10 MB , i can handle it by php and warn user that this file is too large
if($_FILES['pro-pic']['size'] > 2000000)
{
die("TOO LARGE");
}
But my problem is by uploading 5.10 MB file , Request entity too large error will be lunched and rest of my php code won`t work
I have checked post_max_size and upload_max_filesize they are both set to 8MB
But i get Error on 5.10MB !
And I need to find way to handle files even larger than 8MB because there is no way to guess what user may try to upload ;) and i don`t want them to get dirty and broken page because of REQUEST ENTITY TOO LARGE ERROR
Is there any way too fully disable this Error Or set upload_max_filesize and post_max_size to infinity ?
You need to set SecRequestBodyAccess Off.

Is there any way to get size of POST-request body in PHP?
As simple as:
$size = (int) $_SERVER['CONTENT_LENGTH'];
Note that $_SERVER['CONTENT_LENGTH'] is only set when the HTTP request method is POST (not GET). This is the raw value of the Content-Length header, as specified in RFC 7230.
In the case of file uploads, if you want to get the total size of uploaded files, you should iterate over the $_FILE array to sum each $file['size']. The exact total size might not match the raw Content-Length value due to the encoding overhead of the POST data. (Also note you should check for upload errors using the $file['error'] code of each $_FILES element, such as UPLOAD_ERR_PARTIAL for partial uploads or UPLOAD_ERR_NO_FILE for empty uploads. See file upload errors documentation in the PHP manual.)
If you're trying to figure out whether or not a file upload failed, you should be using the PHP file error handling as shown at the link below. This is the most reliable way to detect file upload errors:
http://us3.php.net/manual/en/features.file-upload.errors.php
If you need the size of a POST request without any file uploads, you should be able to do so with something like this:
$request = http_build_query($_POST);
$size = strlen($request);
My guess is, it's in the $_SERVER['CONTENT_LENGTH'].
And if you need that for error detection, peek into $_FILES['filename']['error'].
This might work :
$bytesInPostRequestBody = strlen(file_get_contents('php://input'));
// This does not count the bytes of the request's headers on its body.
I guess you are looking for $HTTP_RAW_POST_DATA
