Directing form to different handlers?

Hi all. I realize this is more an HTML question than PHP but I'm sure someone here can help.

I have several forms with lots (dozens) of text inputs. If the user presses the "Update" button I want the
form handled by "update.php" but if they press "Delete" it needs to be handled by "delete.php" or
"add.php" and so-on depending on the button they press.

But when establishing the form I can only have <form method="POST" action="delete.php"> or "add.php" or whatever.

Is there a way to direct the content of the form do a different handler depending on the button?

I know I can use javascript to direct to a constructed URL and append
?name=smith&address=hishouse&telephone=28376.....and so on but this is not practical when there are
dozens of entries....the URL becomes massive. I prefer to use "POST" and then use PHP to extract the POST array.

Any ideas?

Much appreciated.
Angus

Yes, have the form submit to the URL that presented the form. Have THAT
PHP script determine which button was clicked. Then delegate to the
appropriate handler function.

Cheers,
Rob.

RE: spawning a process that uses pipes - doesn't terminatewhen webpage download is canceled

hi robert.,,

now you've got me curious..

you state...

-Use something else to pass the data back to the user... popen() comes to
-mind or proc_open(). Then disable auto abort on user disconnect via
-ignore_user_abort(). Then after sending periodic data chunks, check the
-user connection status via connection_aborted(). If your script finds
-that the user has aborted, then kill all the processes in the pipeline
-from the PHP script before finally aborting the PHP script itself.

but if the user is using a browser session... which has a web server
connection... are you siggesting that the server app spawns off a child
process via the popen, and that the child somehow connects to the existing
browser session??

walk through the psuedo logic/flow of this if you don't mind.. i must be
missing something..

thanks

Re: PHP vs ASP.NET

Hello,

ASP.NET is not a language. It is more like a framework that can run
multiple languages. It can run VB.NET, C# and even PHP (although it is
not usual).

I am not sure what are the current numbers, but the latest statistics
that I have seen Apache was running on 72% of the Internet Web servers
against only 17% of Microsoft IIS. Although you can run ASP.NET on
Apache via mono, that is unusual.

Also PHP is the most popular Apache extension present in between 40% and
50% of Apache installations. This means that PHP is present in 1/3 of
the Internet Web servers, which represents about half of the PHP market
share.

This article provides more details about PHP market share.

http://www.phpclasses.org/blog/post/95-How-large-is-the-PHP-market.html

As of ASP.NET becoming more popular than PHP, I don't think that even
Microsoft believes that is possible. Actually Microsoft is very
concerned that PHP runs well on Windows and is sponsoring a lot of PHP

mysql connections

how do I make a permanent connection to mysql database and what is
difference between mysql_connect() and permanent one?

If I make connections in one file and  redirect it to another file do
I keep connection (permanent / standard)?

Do I lose connection only when I type mysql_close (permanent/ standard)?

if I select different database between the php program do I need to do
something extra along mysql_select_db("dbname",$link)?

If I opened db in another php file, where do I get the $link variable
from = mysql_connect (when selecting another database)?

Thanks in advance,

I'm already doing something like that... here's what I have basically

$o = popen($cmd);
while (!feof($o)) {
  $buffer = fread($o,4096);
  echo $p;
}
exit();

Ok so I can add in the statements to stop auto aborting, use connection 
aborted... but how do i kill the process chain itself? If I simply pclose 
the process it has the same effect - the other spawned processes keep 
running. I figured out what's happening is the lame process keeps going 
utnil it finishes, and apparently is sending its data to the proverbial bit 
bucket... and in a process tree it moves from being under the http process 
to being under init itself...

Re: Anyone know whats the best way to learn PHP

I don't think there are any substitutes for good books but
www.phpvideotutorials.com has screencasts. I have really enjoyed them.
There are free ones and paid ones. If funds permit I would recommend the
paid ones, there are hours and hours of them. It does not work out to be
much at all per hour. The free ones are of course the place to start
however.
