Description Seth Fitzsimmons 2006-04-25 06:27:51 PDT

Adding a onsubmit handler to a multipart form with a file input causes the file to not be POSTed to the server.

Comment 3 Alexey Proskuryakov 2006-04-25 10:20:19 PDT

I have tried removing the onsubmit handler, and the output from the script didn't change ("Array ( [title] => sometitle )"). Furthermore, it's the same in Firefox.

Could you please clarify how to reproduce the problem?

Comment 4 Seth Fitzsimmons 2006-04-25 10:30:52 PDT

Er, sorry.  I need to provide a better reduction.

Comment 6 Alexey Proskuryakov 2006-04-25 10:52:45 PDT

The updated script works as expected for me (i.e., I cannot reproduce the bug):

Request:
Array
(
    [title] => sometitle
)

Files:
Array
(
    [file] => Array
        (
            [name] => onsubmit.php
            [type] => text/php
            [tmp_name] => /var/tmp/php7ISaZd
            [error] => 0
            [size] => 124
        )

)

I'm using Mac OS X 10.4.5 with Apache, accessing it locally.

Comment 7 Seth Fitzsimmons 2006-04-25 11:34:49 PDT

That's correct; I need to track down the problem more fully when I have some more time; in the meantime I figured I should make the diagnostic script clear that it _is_ working this way.

Comment 9 Seth Fitzsimmons 2006-04-25 19:33:09 PDT

Upon further investigation, this only happens if the form being submitted has its visibility set to "none" (demonstrated in attachment 7966 [details]).

Comment 10 Alexey Proskuryakov 2006-04-25 21:44:55 PDT

Yes, display:none file input controls are a known bug... Judging form the comments there, WebKit may be not violating the standard, but it is clearly in disagreement with other browsers.
