PHP file input number limited to 20 - php

I have multiple file uploads but the $_FILES seems to be chunked after 20 inputs
var_dump($_FILES); //gives array(20){ ... } although there are more file inputs
This is the public php_info
Which parameter is responsible for this limit ?
As a workaround, I used some javascript:
<input id="input_fileXX" type="file" class="input_file">
----
$('.input_file').on('change',function(){
$(this).prop('name',$(this).prop('id'));
});
This allows to only send the inputs that have change. This is useful when you can't change php.ini.

http://www.php.net/manual/en/features.file-upload.multiple.php
Since PHP 5.2.12, the max_file_uploads configuration setting acts as a limit on the number of files that can be uploaded in one request. You will need to ensure that your form does not try to upload more files in one request than this limit.

When attempting to upload a file in development on Laravel 5 I get stream_socket_sendto(): error

I am trying a simple upload from a file so that a country has a sound file for its anthem attached. I am using PHP 7.2.10 with Laravel 5.7.19.
My form includes a field named anthem and the form commences with
<form id="form-app" enctype="multipart/form-data"
method="post"
action="{{ route('storeCountryAnthemMPOnly',['id' => $co->id]) }}">
The route in web.php is:
Route::post('storeCountryAnthemMPOnly/{id}',
'CountryController#storeCountryAnthemMPOnly')
->name('storeCountryAnthemMPOnly');
and my function in the controller is just:
public function storeCountryAnthemMPOnly(Request $request, $id)
{
dd($request);
}
When I press the submit button I am getting:
stream_socket_sendto(): A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
I cannot understand this and help is greatly appreciated.
File can't be uploaded to the server and it is not the fault of laravel, but your server.
I had the same problem with the same environment. The thing was the file was too large, so it couldn't be uploaded to the temporary location. Although the file wasn't uploaded to the server, laravel still was trying to read it so this is why you get "no address was supplied".
In my case file couldn't be uploaded, because of exceeding size limits, but perhaps in your case, it is another reason why the file cannot be uploaded.
I solved it by changing size and memory limits in php.ini.
memory_limit = 32M
upload_max_filesize = 24M
post_max_size = 32M
Besides size limits, I have one more suggestion: make sure that you have proper permissions to the folder with temporary uploads.
You can also check server logs.
You used Form::model style in your action URL. Change your action in form tag to
action="/storeCountryAnthemMPOnly/{{ $co->id }}"
Did you place a MAX_FILE_SIZE input in your form? If so, then you have to increase the value of it. I had the same problem and could fix it by just increasing the value to the proper one. This is the final size I put in.
<input type="hidden" name="MAX_FILE_SIZE" value="10485760">
I think Laravel is kindda checking this input in the back-scene.

Request Entity Too Large with small files

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.

empty $_POST and $_FILE variable when uploading large files

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.

Zend File upload: File exceeds the defined ini size

Inside my form i define this file upload field:
$this->setEnctype(Zend_Form::ENCTYPE_MULTIPART);
$logo = $this->createElement('file', 'logo');
$logo->setLabel('Group logo')
->setMaxFileSize(5242880) // 5mb
->addValidator('IsImage')
->addValidator('Count', false, 1)
->addValidator('Size', false, 5242880)
->addValidator('Extension', false, array('jpg', 'jpeg', 'png', 'gif'));
However, no matter how small files I upload I get this error: File 'logo' exceeds the defined ini size.
The error message seemed pretty straight forward so I checked the php config (phpinfo() on the same exact page that handles the form)
file_uploads: On
upload_max_filesize: 2000M
memory_limit: 128M
post_max_size: 8M
While those values don't exactly make sense, they absolutely should allow me to upload files up to 8Mb but the upload always failes with the message from above. Even files smaller than 1Kb fail. I also tried removing all setters/validators but it still fails.
While searching for an answer I came across some posts that said that it was ajax' fault but this is a regular form, so now I'm stuck.
Update: I'm terribly sorry to have wasted your time, there was another unclosed form on the page which voided the multipart-declaration. Could have found that out sooner if I had tested with larger files rather than small ones :/
Add enctype="multipart/form-data" in your form. It should solve your problem.
Add
enctype="multipart/form-data"
to your <form> element. Solved my problem.
if you are using script file to render your file , you need to retrieve the enctype info that you specified in form class from your script file. <form enctype="<?php echo $this->element->getAttrib("enctype"); ?>">
Chances are that the php extension fileinfo is not activated.
Please check your php.ini file and increase upload_max_filesize. By default, it is 2M (2 MegaBytes). Also in order to be able to post file with size more than 2M you need to update value of post_max_size
It looks like you're missing the destination:
$logo->setLabel('Group logo')
->setDestination('/var/www/upload')
...
You might want to make sure that the folder is writeable by your web server.
When I commented out the following I got the same error:
->setDestination($this->_config->folder->ugc);
->addValidator(Kvadrat_Form_Element_File::VALIDATE_COUNT, true, 1);
->addValidator(Kvadrat_Form_Element_File::VALIDATE_SIZE, true, 5 * 102400);
(I commented it out as was doing the file uploads separately with FormData)
So I uncommented it and it all worked again.
Your size validator is incorrect. You should use this format:
->addValidator('Size', false, array('max' => '5242880'))
Your validator checks file's size == 5242880, NOT <= 5242880.

Detecting file upload size on the client side?

I'm using PHP for file uploads. In the PHP manual it shows an example using a MAX_FILE_SIZE hidden field, saying that it will detect on the client side (i.e. the browser) whether the file is too large or not.
I've just tried the example in Firefox, Chrome and IE and it doesn't work. The file is always uploaded, even if it is way larger than the specified hidden field.
Incidentally, if the file is larger than MAX_FILE_SIZE then calling move_uploaded_file doesn't work, so it seems the variable is having an effect server-side, but not client-side.
On MAX_FILE_SIZE
Read This:
...At http://pk.php.net/manual/en/features.file-upload.post-method.php and equivalent locations in other formats, it is stated
that browsers take the value of a MAX_FILE_SIZE form field into
account.
This information is repeated elsewhere on the web and in books, but
appears to originate from the PHP documentation (it does not appear in
terms of other server-side technologies).
There is nothing in any of the HTML, HTTP or related specs to indicate
that this is the case (in particular RFC 1867 which introduced file
uploads to HTML doesn't mention it, so it isn't even a case of a kludge
that was mentioned in the first RFC and then dropped) nor does it make
sense in the context of the HTML specs (there is nothing to indicate any
relationship between that particular hidden input and the file input).
The only statements about hidden fields I could find in any of them was
warnings in the security considerations sections against user-agents
basing any file-related operations on anything mentioned in a hidden
field.
No browsers appear to perform this as an "extension". Indeed given that
there are potentially other possible meanings for a hidden field with
that name in an application handling several file uploads, it would have
to be considered a design flaw any any did.
I submit that there is no such mechanism in mainstream browsers (if any
at all) and indeed shouldn't be. Reference to it should be dropped from
documentation.
I'd further suggest that since this idea has propagated from this
documentation elsewhere that a note about it not working should to be
added.
If a mechanism is required or desired for more rapidly handling this
sort of file handling issue then it requires functionality to allow PHP
to intercept streams being uploaded before request completion, which
would be completely different to how this documentation suggest it
should be dealt with, even if it was true...
http://www.juangiordana.com.ar/blog/2007/12/08/max_file_size-erroneo/
the code below come from swfUpload php implementation:
// Check post_max_size (http://us3.php.net/manual/en/features.file-upload.php#73762)
$POST_MAX_SIZE = ini_get('post_max_size');
$unit = strtoupper(substr($POST_MAX_SIZE, -1));
$multiplier = ($unit == 'M' ? 1048576 : ($unit == 'K' ? 1024 : ($unit == 'G' ? 1073741824 : 1)));
if ((int)$_SERVER['CONTENT_LENGTH'] > $multiplier*(int)$POST_MAX_SIZE && $POST_MAX_SIZE) {
header("HTTP/1.1 500 Internal Server Error");
echo "POST exceeded maximum allowed size.";
exit(0);
}
// Validate the file size (Warning the largest files supported by this code is 2GB)
$max_file_size_in_bytes = 2147483647;
$file_size = #filesize($_FILES[$upload_name]["tmp_name"]);
if (!$file_size || $file_size > $max_file_size_in_bytes) {
HandleError("File exceeds the maximum allowed size");
exit(0);
}
This probably only works on Firefox 3.6 for now:
<script type="text/javascript">
function checkSize()
{
var input = document.getElementById("upload");
// check for browser support (may need to be modified)
if(input.files && input.files.length == 1)
{
if (input.files[0].fileSize > 1024) /* or maybe .size */
{
alert("The file must be less than 1KB");
return false;
}
}
return true;
}
</script>
<form method="post" enctype="multipart/form-data" onsubmit="return checkSize()">
<input type="file" id="upload" />
<input type="submit" />
</form>
See http://www.w3.org/TR/FileAPI/.
As far as I know there is no simple, cross-browser solution to achieve this. The only working solutions are Flash or Java based since these technologies can access filesystem and get file info.
Example scripts: YUI2 Uploader, FancyUpload, SWFUpload
If you are using MAX_FILE_SIZE hidden field properly, the file uploading will just stop when the uploaded size reaches the specified value. And thus saves users the trouble of waiting for a big file being transferred.
You have to check whether the file upload is stopped, in the server side by using the error code generated.
if($_FILES['userfile']['error'] == 2)
{
die("Maximum file size Exceeded");
}
