File upload size check failing

Hi all,

I'm having a few problems with a file upload script that I'm writing. It seems that my error trapping to check for maximum file size is not working properly.

Here's my form code (stripped down a bit and just the usual basic stuff):

[PHP]

<form name="upload" method="post" action="process_upload.php" enctype="multipart/form-data">
  <input type="file" name="file">
  <input type="submit" name="Submit" value="Submit">
</form>

[/PHP]

And here's the code at the top of  "process_upload.php":



[PHP]<?php

$max_docsize ="2000000";
 
      if(($_FILES['file']['size']) > $max_docsize){

      echo "File is too big";
      exit():
}
?>
[/PHP]

PHP is throwing a wobbly complaining that the MAX_UPLOAD_SIZE has been exceeded and that it was unable to process the file.
…yet if I knock the $max_docsize variable down to something really small such as "100", then try uploading a small 400kb file, the error trapping works.
It just seems that anything over 2mb is not being picked up by the script before PHP tries to process it…

I don't want/need to alter to the php.ini file on the remote server, ... all I'm trying to achieve is that my error message and exit() commeand works before php throws its wobbly.

I'm stumped!!!
GGrrrrrrr  :(

Check the limits in your php.ini


you might have it set to 2MB

change it to say 6MB and see what happens

I cannot change the limit on the php.ini file as it is determined by the hosting company.

I just want a friendly error message to appear instead of the "MAX_UPLOAD_SIZE has been exceeded" error which is appearing.

Can anyone help??... Please

<input type="hidden" name="MAX_FILE_SIZE" value="3000000098">

then include this code before you upload the file to overide what the php.ini limit is. However if the admin has put restrictions on the size of files you can upload you cannot do it.

You code now looks like

<form name="upload" method="post" action="process_upload.php" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="30000">
  <input type="file" name="file">
  <input type="submit" name="Submit" value="Submit">
</form>
