The form is being submitted to the current URL which will stop any
javascript executing at the time. What you need to do is prevent the
form from being submitted, or control when it is submitted. Instead of
using the onclick attribute on the button you should be using the
onsubmit attribute in the form tag to control this. Fairly good
explanation of this here:

Great suggestion, but I think an "upload file" a different critter.
http://www.htmlcodetutorial.com/forms/_INPUT_TYPE_FILE.html
For example, I took my above code and changed it like so --
<form method="post" enctype="multipart/form-data"
onSubmit="javascript:sndReq()">
<input type="file" name="image" value="30000">
<input type="hidden" name="stage" value="1">
<input type="submit" value="submit">
</form>
-- and the result was the same. The file uploaded, but nothing happened.
I also took the code you referenced, exactly "as-was" and I changed the <FORM
statement to --
<form method="post" enctype="multipart/form-data" onSubmit="return
TestDataCheck()">
-- and it didn't work the way one would expect either.
Apparently, the "built-in" upload-file thing has it's own way of processing
events. What do you think?
Thanks for your time.

Maybe I'm not understanding what you're trying to do. I think you're
trying to show an animated GIF before starting the file upload. Is that
right? If it is, this is what you need to do...
The form, with onsubmit="return sndReq()". sndReq does the AJAX image
thing (although I don't know why you're using AJAX here, but it doesn't
matter). sndReq *must* return false!!
When the AJAX request completes the response presumably gets handled by
another JS function. That function does whatever it needs to with the
AJAX response, and then submits the form. I'm not sure if
programmatically submitting a form calls the onsubmit handler, you'll
have to check that. If it does just make sure sndReq does nothing on the
second call except return true - that will tell the form it's ok to do
the submit.
Another way you might want to consider for this is to use an iframe. Set
the target of the form to an iframe, that way the JS running in the main
page will not get stopped.
Hope that helps.

That's exactly what I'm trying to do.

>(although I don't know why you're using AJAX here,
I'm using ajax because it's a method to inject an image in a DOM div without
having to reload the current page.
My method is pretty straightforward.
1. Present the user with a page that has the typical "Choose File" and "Submit"
button for uploading an image file.
2. After the user selects the file he/she wants to upload, they then click
"Submit" and the file uploads (a wait) and then they go to the next step on
another page.
All I want to do is present an image during the "wait".
Is there an easier way to do this?
I'll investigate your suggestion to look into iframes.
Thanks.

There is no need to hit the server for this. Simply include "display:
none;" in the style for either the img tag or the div containing it so
it's not shown when the page initially loads. In the onsubmit for the
form change that display to 'block' to show the image. This also avoids
the need to postpone posting the form since the image has already loaded.
Image...
<img id="waitimg" src="/whatever.gif" style="display: none;" />
Form...
<form ... onsubmit="document.getElementById('waitimg').style.display =
'block'; return true;">

Ignore that. An iframe is not the best way to solve this.

Bingo!
That works slick ! While I *think* I know css, it would have taken me a long
while before I would have turned to css to solve this.
Your solution works much better than the convoluted code I was writing. It's
clear that I need to understand js better.
Thanks much Stut.

I recall trying this (exactly this I think) a couple months ago and
finding that it works in most browsers, but not in Windows IE6 (of
course). Is it working in Windows IE6 for you?
I got a working upload progress bar by using Uber Uploader

Hello *,
I am on over 100 Mailinglists and want to make my archive (monthly
tarbals) public availlable. my problem is, that they are around
20 GByte compressed archives and I want to prevent peoples to suck
the whole archive at once...
I was trying several things but failed.
Does anyone have a code sniplet which limit clients to, e.g. four
downloads, per day?
I think, I must use a database or something like this, because I
must track th IP, date, time, and the used download client...
I think, downloads limiting by creating accounts with passwords
will not help since spamer can create Yahoo or Hotmail accounts
faster than you can stop it...
Or should I pass the downloads via this nifty PIC/IMAGE verification,
where $USER must type in the numbers/letters created by a php script?
Greetings
Michelle Konzack

Michelle:
If it was my problem, I would have people register and store their registration
(logon and password) in a dB and require them to accept cookies. I think that
would both slow-down and limit downloads.
As for PIC/IMAGE thing it's called CAPTCHLA and that would help keep out
spammers, but you would cut out the visually impaired. You might want to read

To remove a single element you can use unset: unset($arr[0]);. To
remove all the elements with integer indices you could just loop, check,
and unset those ones.
What do you need to do this for? Your examples looks like arrays got
from mysql_fetch_array. If this is so, using mysql_fetch_assoc() instead
of that will get you only the associative array.

if you pull this array from mysql use this:
$query = mysql_query("SELECT * FROM table");
$result = mysql_fetch_array($query, MYSQL_ASSOC);

You misunderstand my question. I know the limitations of javascript. The
server won't respond to events registered in the browser. I write tons
of forms that are all processed
by the client with javascript. I have written ferocious regex filters
that hack apart form submissions before they even leave the client. I
have set it up so if the client doesn't
have javascript enabled, the form won't submit if it is going to the
server. That is why as much as possible I shift form processing to the
client as much as possible, for
security and to off load work to the client. I use php to dynamically
write js files when necessary, anticipating what data will be requested.
I didn't (misunderstood), what I told you is that you cannot rely on
javascript (actually, that would be "anything coming from the client")
You need to do validate on the server, and it doesn't matter if you
already did it on the client or not (simply because you cannot know that
for sure)
This is a problem that is more a matter of programming theory. I have
posted to javascript forums and lists and have never got a response.
I will be applying this to dhtml which the server won't and can't do but
may help things along with Ajax.
Just a simple suggestion about how to reorder arrays if you have a few
words and suggestions. I'm not looking for free training.
I have been learning and using php and javascript for some five years
and have developed my own approach to testing and debugging
and such. So I am not really a newby. I have made the dumb mistakes of
asking for help from forums and lists when it was just a dumb
syntax error that I couldn't expect anyone but my self to find, which i
have in 99.9% of the cases. Some times it is nice to get some
quick help from a list and I will try to return the favor when ever
possible to the next person looking for help that I have some answers for.
Well, I asked you for the actual (JS) code you're using (the one that
didn't work in all the intended browsers), that way someone might be
able to help you (I will if I can)

I once for just the fun of it, made a regular expression to solve

but only on some basic examples. It should support both single and
double quotes.
$str = 'bass "electric organ" bagpipes';
preg_match_all("/(?<=('|\"))[^\\1]+(?=\\1)|[^ \"']+/",$str,$match);

Chris, Richard,
Thank you for your advice.
Inserting "sleep(1)" into the script seems to have done the trick.
I will also look into the other alternatives you suggest, such as
different mail programs and the error output of mail() to see if I can
optimize the system further.
Thank you for taking the time to help.
