Need help writing own functions

[Dariusz]

I would like to try writing my own functions, so as to keep some code
within the same PHP file rather than make multiple PHP files.

What I am having a problem is is how to call a function when a php
generated HTML form is "submitted" and to put the variables back into
another function within the same PHP file.

I have figured how to pass variables to a basic test function I wrote, but
not how to call a function within the same PHP file AND from a form.

Can't seem to find any good examples online.

Any help appreciated.

I'm not sure you understood the "Server side" of the PHP.
What you can do is a HTML Form that points to the script itself (use
$_SERVER['REQUEST_URI'] in the action param of the form)
and add some hidden var if needed to know where you come from.

You can not call a PHP function with a 'Submit' button whitout sending
the form.
If you need such behaviour you should try JavaScript instead.

I don't know if I explained it properly, so I give it another shot.

If you have a HTML form, you can call a PHP file and post or get all the
variables from the form into the PHP file to do with as you please. What
I'd like to know is is it possible to call and execute a function within
the PHP file, and pass all the variables at the same time?

Trying to stay clear of Java / Javascript and anything like that. If
anything, I just keep the PHP files seperate instead of having one big file
with functions (I should learn how to do functions - and this script
should suit).

Not really. A request always goes to a file. It's up the code in the global
scope in the file to call the functions.

In general, it's better to associate one "web-page" with one file. Take a
look at the source of www.php.net. Just scroll down and click the "show
source" link. Very good example of how to structure a site in a straight
forward manner.

When you parse the arrays containing the POST and GET vars, you can make
your own array, containing all the variables you want to keep, like this:

$input = array();
foreach(incommi ng_vars as $key => $val) {
$input[$key] = $val
}

The above code is of course just pseudo code, and you'd have to either
find or write your own function that actually parses the input and stores
it like I've tried to describe. (The "parse_incoming ()" function that the
Invision Board crew has made, is really good.)

Now that you've got all incoming vars in an array, you can either pass that
array to your fu like this:

$retval = myfu($input);

Or you could simply tell your fu to use the global var $input:

function myfu() {
global $input; //Tells the fu that it can use the global var $input
return $input['a'] + $input['b']; //Or something else...
}

To get all incoming vars and store them in an array is easy.
The trick is to find a way of doing it that secures that no
"bad" variables has snuk in there...
