Hmm, after a bit of testing I find that the MAX_FILE_SIZE tag is useless to
say the least (probably because no browsers support it?)
In all of NN, Opera, IE having the tag does /not/ prevent the file from being
uploaded. Thus if I set MAX_FILE_SIZE to 100000 (100K) and upload a 5MB file
what happens is:
1) you still have to wait for the whole 5MB to be uploaded
2) php sees the MAX_FILE_SIZE setting is exceeded then discards the file
If anyone wants to run their own tests here's my test script:
======================================================================
<html>
<body>
<form enctype="multipart/form-data" action="<? echo $z_PHP_SELF ?>"
method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000">
<table border='0'>
<tr valign="top">
<td align="right">Gimme a file</td>
<td align="left"><input type="file" name="file" size=60></td>
</tr>
</table>
<input type="submit" name="action" value="GO">
</form>
<?
$file_size = $HTTP_POST_FILES['file']['size'];
$tmp_filename = $HTTP_POST_FILES['file']['tmp_name'];
print_r($HTTP_POST_FILES);
?>
</body>
</html>
