max_file_size by upload's

[olaf]

Hi,

using a max_file_size is no problem if you don't reach the maximum what is default allowed by the server.

for example:
my server maximum is: 2 mb

in my script i use a smaller value like 100 kb (for image uploads)

if i upload a file what is bigger than 2 mb my size check will not work like

$maxSize = 102400;
if ($temp_filename < $maxSize)
{
move_uploaded_file($temp_filename, $destination_filename);
//and the rest of the code

Is there a solution?

do something like this:

$maxSize = 102400;
$filesize = $_FILES['userfile']['size'];
$filename = $_FILES['userfile']['name'];
$tempname = $_FILES['userfile']['tmp_name'];
$uploadfile = $_SERVER['DOCUMENT_ROOT'].'/files/' . $filename;

if($filesize > $maxSize)
{
	die('file size is too big maxium size is ' . $maxSize . ' bytes');
} 
else
{
	if (move_uploaded_file($tempname, $uploadfile))
	{
		echo 'File Uploaded ..';
	} 
	else
	{
		echo 'Cannot Upload ..';
	} 
} 

replace 'userfile' with the name of you're form field name.

Hi,

thanks for the answer. Your standard error message handles the error in case of larger allowed.

But the problem still exists, i can't inform the user that the file is much to big, because php knows the filesize only after the file is uploaded.

oh, i understand what you mean now. I have never understood why max_file_size doesn't do anything... i have tried lots of times in my code to do what you are trying to do and for some reason the entire file has to be uploaded before the user gets an error ..

even the php.net site shows how to use max_file_size , yet it doesn't work at all the way we want it to .. that is, to let the user know if the file size is too big instead of waiting for the whole file to upload before erroring out.
