Variable from another variables value PHP

ok, I have this tricky problem. Here's my situation:

I have a form which html code I get from a db. I mean the html code of the answer fields like the inputs and textareas and so on.

Then I should process the form when it's submitted. I have also the answer fields's name field names stored in the db where I get them so I know what is the name of every field that comes to my process page.

The problem is that how can I insert them into db because I need a variable which is the same name as the other variables value. Here's an example:

I get the name field name from db:

code:

$sql3 = mysql_query("SELECT * FROM ir_vastaustyyppi WHERE tyyppi = $vastaustapa ORDER BY vaihtoehto ASC"); while($result = mysql_fetch_array($sql3)) { $nimi_kentta = $result['nimi_kentta']; // Here I do the insert mysql_query }

ok now I have the name fields name stored inside that $nimi_kentta variable. But let's assume the value is "name" so in that case I need a variable $name so I can insert them to db. So how do I create a variable name on the fly according to what values the $nimi_kentta gets ? Save me!

I solved the problem. Was actually quite easy. After I got the name of the name field I just recieved the variable like this:

code:

$name = $_POST[$nimi_kentta];

and then I could add it to database using the $name variable. Quite funny that it took 5 and half hours for me to get it right

Really? Here is another thing you could try:
just put this somewhere at the top of the script

code:

extract($_POST);

This will create the variables automatically from arrays. Like it will create a variable called $nimi_kentta with the supplied value by form.

yes, but the thing is that with PHP you can use POST variables without any action at all but you had to do it like that to make it work. But the satisfaction was great when I finally solved it
