Here's my position on this. Randal is a very respected member of the Perl community, but in this case I think his response was a bit extreme, especially as it didn't spell out *why* he was so annoyed. First of all, what's "The FAQ"? Perl, and the various version of Perl, have a lot of different FAQs. In this case, Randal was referring to the general Perl FAQ, sub-section "How do I check a valid mail address?" http://www.perldoc.com/perl5.8.0/pod/perlfaq9.html which is, somewhat confusingly, not in the regex FAQ, is about checking the *validity* of addresses, and starts with a blunt statement that it's impossible. The whole thing is pretty much in the context of "I've been given an address -- how do I tell if it's valid?", and it does indeed address serious issues, which not many people know about, because email addresses can take a number of different and obscure forms and still be valid. However, Sara didn't want to check the validity of email addresses. All the addresses she wanted to fix were valid, known to her, and presumably in one of the more normal forms, as in [EMAIL PROTECTED] -- if Sara had said "I want to match email addresses in the form '[EMAIL PROTECTED]' and replace the '@' symbol", then I submit that the solutions would have been just fine. Randal's right, people should read the FAQ. Everyone go and read it right now. But the FAQ entry he mentioned doesn't directly address the problem at hand, and the solution promised would almost certainly have sufficed. I wish someone had answered more like this: -------- The following regex [regex] will find most normal '[EMAIL PROTECTED]' email addresses -- but please, if you haven't, read the FAQ, [address] because this is *not* a regex that will match every valid email address. ---------- jh > ATTACHMENT part 3 message/rfc822 Subject: Storing Form Data without submitting it. Date: Wed, 26 Nov 2003 15:14:53 +0100 From: "Marcus Willemsen" To: Hi everybody, I' m not sure this is the right list to ask this kind of question but I don't know where else. We are using html forms to insert and update news articles (texts) stored in a mysql database. Ever so often one of our journalists forgets to press the submit button or his computer crashes and everything written so far is lost. Is it possible to built something like an "autosave" function that submits the form data automatically every couple of minutes and updates the database entry? Any hint's where to look up these kind of things?

Because this is a client side action (at least what triggers it) you are probably going to want to look to javascript. I believe you can setup timers in javascript that will trigger actions, that will be the hard part, the easy part is the action that is triggered is just a standard submit of the form, then the server side script would just store the info and reprint the form with the fields filled in the same, which I am assuming you can do. As a suggestion I would add (at least) two features, 1) a "clock" that displays a form element that is continually updated with the number of seconds left until the next save (as you will have to reload the page and there is nothing your journalist will hate more than being in the middle of a great thought and having his page reload on him) which brings me to... 2) have a "reset" clock button, so that if the user *is* paying attention they can reset it so that the refresh doesn't happen... Which brings me to "not refreshing" since I know you will ask. Presumably the javascript could build a request and submit it in a separate object (possibly in a popup window) which would provide all of the data from the form, the response would be that the form data has been saved and then wait a second or two and close the window automatically, then theoretically you wouldn't have to refresh the page. But now we are getting much more into the Javascript land where I am not nearly as strong..... Obviously you should also store some sort of status so that a half story isn't posted online just because it is saved in the database... Now that I have thought through it more this is an interesting idea and I might just have to play around with it :-)... http://danconia.org > ATTACHMENT part 5 message/rfc822 Date: Wed, 26 Nov 2003 08:30:53 -0600 From: Andrew Gaffney To: [EMAIL PROTECTED] Subject: Re: Storing Form Data without submitting it.

I believe there is an HTTP status code that tells the browser that the form was successfully submitted, but not to go anywhere. I don't know what it is off the top of my head, but I think it would work in this case. -- Andrew Gaffney > ATTACHMENT part 6 message/rfc822 From: Bob Showalter To: 'Andrew Gaffney' , [EMAIL PROTECTED] Subject: RE: Storing Form Data without submitting it.

Would that be 204 No Content? http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.5 I've never used that before. I wonder if the various browsers behave properly when they get that? > ATTACHMENT part 7 message/rfc822 From: Ash Singh To: [EMAIL PROTECTED] Subject: Redirecting to a different url with cgi Date: Wed, 26 Nov 2003 16:19:39 +0200 v\:* {behavior:url(#default#VML);}o\:* {behavior:url(#default#VML);}w\:* {behavior:url(#default#VML);}.shape {behavior:url(#default#VML);} What is the perl code to redirect to a new url, in cgi.
