Limiting File Size on an upload....

austinderrick2

How do I limit file size on an upload using a form?

just check after they post the file, its stored in
$_FILES['theVarName']['size'];

heres a cutout of one of my old pages

$max_size=60*1024; 	

$file=array("name"=>$_FILES['fileName']['name'],
					"tmp"=>$_FILES['fileName']['tmp_name'],
					"type"=>$_FILES['fileName']['type'],
					"size"=>$_FILES['fileName']['size'],
					"error"=>$_FILES['fileName']['error']);

if($file['size'] > $max_size):
	$valid=false;
	$error.="File size exceeds maximum allowed [ Max: $max_size ]<br>";
endif;

in $_FILES['fileName'] the fileName comes from:
<td align=right><input name="fileName" type="file" size=35> </td>

if($_FILES['userfile']['size'] > 1048576) // 1 mb, size in bytes.
{
      echo 'file is too big';
      exit;
}

If you do that, don't forget to unlink() the file also

well, your code might do the same as mine will.., but my method is more efficient. no pun intended.

besides, i saw all that code and thought it was too much 😉
typically i dont read every single post in every thread.. i like options 🙂

Some more option : 😉

The php.ini holds also max_file_size.

Is there a way to change this value in an upload-script?

seby

you can set a max_file_size (hidden form) and specify a size (it cant be greater than what is specified in the php.ini), this is good to tell the browser that the file is too big instead of letting the user upload an entire file only to find out that its too big.

I saw this option earlier...for beter understanding:

upload_max_filesize (php.ini) = 2mb
max_file_size (hidden field) = 3145728

will say that my maximum upload could be 3mb?
and php will give me this info before upload?
