Calling External File

[SamMan]

I am fairly new to PHP programming, and I'm trying to get my head around
this one...

I have a form that I am doing validation on via PHP within the same page, so
if there is an error, a message will show to the user above the form. If all
goes well, I would like to call a processing script that I have already set
up and working to format the users response and send it out to a specified
e-mail... I'll call it processing.php

Is there a way that I can, if the form is filled out correctly, make a call
to processing.php, that will totally leave the control of form.php and do
it's processing?

I hope I'm making myself clear...
Thanks.

header('Locatio n: http://www.example.com/processing.php' );
exit;

The problem is that if I use the header method from within the first page
(form.php) I get an error that the headers have already been sent, or
something to that effect.... At least this is what I recall was happening
yesterday. I will give it a try again, and let you know.

Thanks.

basically use hidden flag fields to tell you when everything is okay

if (isset($flag))
{
form method=post) // using no method says to use this file
<input type=hidden name=flag value=1>
fill in the form and if it is incorrect have them make corrections
if no corrections needed, then add a hidden field called okay
form with all correct variables action=processi ng.php
} else
{
form method=post) // using no method says to use this file
<input type=hidden name=flag value=1>
other input fields
submit[color=blue]

The error that I'm getting is "Cannot modify header information - headers
already sent...". Unless I put it at the very top of the page, then it
works. This will be another challenge, as I will need to put the validation
code at the top of the page (I'm assuming) and I would like any errors to be
displayed in a specific location in the form.

Back to work!
Thanks.

Matthias,

I think I have this sorted out. Doing a test page...
All the validation code is at the very top of the document, before anything.
This code checks for errors and sets a flag. If there is no error ($flag=
="false"), the processing script is called (using the header() function). In
the location that I want the error's to display, the flag is checked, and if
true, the errors displayed. Of course, this is a very simple test of the
logic.

I believe I will be able to easily transfer this logic to the form at work.

Thanks for stimulating my brain!

That's the way I write my scripts. :-)

I ended up doing it a little different....
Everything is still at the top of the doc, and a flag is set on error, but
if none, the processing (formatting of the e-mail message) is done right
there. If the message is sent successfully, then a header function is used
to redirect to a thank you page, if not, an error page.

I even took it a step further. I have made as much of the scripting into
includes as I could. I tried to separate the error checking & processing
into two separate includes, but it didn't like that, so I just made one
include. Any error message that is to be displayed is handled by an include
also. This makes for a much cleaner looking page, and helps separate the
view from the model.

Thanks again!
