Safari and PHP, File Uploads Solved!

Filed under: PHP — geoff @ 12:16 am

I posted recently about image file uploads to PHP, and how they would fail in Safari.  It was a nasty bug that wouldn’t go away, but I finally discovered the problem.  On my upload form, I was using javascript and CSS to hide the form fields and replace them with an “Uploading files…” prompt.  It seems that there’s a bug in Safari where hidden forms will contain no values.  So, in hiding my form, nothing was being sent to my site!

I was wondering why my $_FILES array was empty - it just didn’t make any sense.  After I stopped hiding my form, I instead covered over it with the ”Uploading…” dialogue using relative positioning.  Now the $_FILES array was being populated and the files sent via POST.  It works like a charm now!

  1. Just wondering, did the bug also exist if you made the form invisible (as opposed to hidden) ?
    CSS:
    visibility=hidden;

    I don’t have Safari to test on.

  2. As I’ve run into the same right now …
    yes, it happens also if you just hide it through visibility.

  3. I got the Same problem
    was working fine with IE 5.5 and 6,
    Firefox was sending the form , at least in parts , but the files were not uploaded by Firefox.

    After reading this article i found that:

    I usually put my forms , in between table cell or rows, That was preventing some problem with multiple forms , and the way the browsers display them, something they were acting like instead of being seamless.

    Firefox doesnt like’s the forms to be “not shown” i mean that , even if it is there in the page, and it properties are the basic one,
    the was in between a table cell , usually nothing goes there.
    but it was beeing used correctly by explorer.
    and the were in the table cell so they can be seen

    and i had no problem with form having a style of theire own.

    after reading this , i moved the in a normal place eg: in

    instead of

    this way firefox , send the whole and the uploaded files correctly

  4. I was reading your SAFARI and PHP solution, thanks, I will investigate this. My web site, when the users submit or calculate their forms get a “not a number” error message when they swear they are putting in values. Does not happen with firefox on the MAC.
    Have a look at the site, vote and tell everyone you know to get the vote out!
    (Assuming you live in the USA)
    Thanks again!
