i have two files:
First:
--------------
<form action="admin_add_drink.php" method="post">

Short Drink:<input type="radio" name="shortd" />
Long Drink:<input type="radio" name="longd" />

<br></br>
Drink Name <input type="text" name="name" />
<br></br>

Ing:
<br></br>
<textarea name="ing"> </textarea>
<br></br>

Opis:
<br></br>
<textarea name="dis"> </textarea>
<br></br>
<input type="submit" />
</form>
--------
second file
$file=fopen("$_POST[name]","w")or exit("no way !");

1.Those two write a file in the root directory with a name you put in "input". The thing is that I dont know how to put it, in a directory chosen ealier (Those two radio buttons). You meant to chose a radio button(long drink directory/short drink directory) that choses a directory and the script should write that new file in there.....
Dose any one know how to do that??

First of all, it looks like the drink type can either be "Short" or "Long" If that is the case, the way to setup the HTML radio code would be something like:

<input type="radio" name="drink_type" value="short" />Short <br />
<input type="radio" name="drink_type" value="long" /> Long

Then (completely ignoring security here) your PHP code would be something like:

$file=fopen("$_POST[drink_type]/$_POST[name]","w") or exit("no way !");

If you truly mean to put the file in the root folder, you'd add a forward slash before $_POST[drink_type]
