[SOLVED] Very Simple Variable Help Needed!

[Warptweet]

Hi there.
This may seem confusing, but this is really just variables.
I have a form....
This is what it has.

Browse Files (Uploader part, I already got this covered)
Flash Name:
Flash Author:
Flash Description:

And their names are...

uploadedfile (dont worry, I got the uploader part covered)
flashname
flashauthor
flashdescription

When you submit the form, it goes to upload.php.
At my upload.php, how can I call the content submitted?

Would I use....

uploadedfile (dont worry, I got the uploader part covered)
$flashname
$flashauthor
$flashdescription

I'm not exactly sure how I would call or use the text typed inside the forms, can anyone help? Oh, and just in case you were wondering, I'm creating a PHP file in the script with these variables in them.
Although, I have some problems with this also, which too have to do with simple variable problems.

$ourFileName = "testFile.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);

Okay, so, for the first line.
$ourFileName = "testfile.txt";
How can I make it so that "testfile.txt" is actually the name of the flash file that has been submitted? (For instance, in the "browse file" part of the form, I upload flash.swf, I need $ourFileName = the .swf flash file I uploaded)

Second line
$ourFileHandle = fopen($ourFileName, 'w') or die ("can't open file")
I need it to write all three things submitted in the forms

Flash Name
Flash Author
Flash Description

Thanks! It's simply confusing how I get what is submitted in form text boxes into variables on the submitted page. I appreciate any help, thanks a million in advance!

it depends on what the form method is

[Warptweet]

It's using the "submit" method, is that what you mean? And it leads to upload.php

[chronister]

the only 2 methods for a form to submit is POST and GET


if it's POST, then you use

$var_name=$_POST['fieldname'];

if it's GET then

$var_name=$_GET['fieldname'];

[Warptweet]

I found out it's POST.

So...
Thats mean I would do this...?

$flash=$_POST['flashname']

If so... sweet! Thanks!
Today is the first day I actually started "learning" PHP.
I think I'm getting the hang of it!

[chronister]

$flash=$_POST['flashname'];

make sure you don't forget the semicolon as that will wreak havoc on your scripts.

[Warptweet]

Oh, lol!

ONE MORE THING!!!

$ourFileName = "testFile.txt";
Thats line of code. Can I do this...?
$ourFileName = $_POST['flashname'];
OR can I do this? (after doing $flashname = $_POST['flashname'];)
$ourFileName = $flashname

[chronister]

I would say skip the middle man and just make

[code]
$ourFileName=$_POST['flashname'];
[/code]

While your learning anyway, but you want to look into verifying what the user has submitted to you. A rule of thumb I have heard many times in my short PHP career,... Don't trust any raw data from users, always make sure it is what your expecting be it alpha-numeric, email, or whatnot.
