Help with radio input

[exer]

Hi guys, before I start I wanna apologize for my english. I'm from Czech Rep and I cant speak English very well.

anyway, What i need is little help with Radio input. I want make something like 'ordering script'. on order.html costumer choose things he wants to buy and on for example form.php it show to him summary, what he chosed and how expensive his order is.

I have this in order.html

    <input type="radio" required name="item" value="200$" onclick='check_value(this, 1)' />
    <input type="text"  name="NameOfItem"  value="Name1" hidden />

<input type="radio" required name="item" value="250$" onclick='check_value(this, 1)' />
<input type="text"  name="NameOfItem"  value="Name2" hidden />

(onclick='check_value(this, 1)' is javascript counting system so its irrelevant)
(of course I have more than one option)

And in form.php i have:

<? echo $_POST["item"];  ?>
<? echo $_POST["NameOfItem"];  ?>

I guess this whole idea with hidden text connected to radio input is wrong. But how can i do it ?.

Simply i want this :
• Thing 1 - 200$
• Thing 2 - 250$
• Thing 3 - 500$
and when he chose for example thing 2 and click to submit on form.php will be :

You chose Thing 2 for 250$

I hope you guys understand me and im sorry for my english again.
thanks for any help

What you ought to do is have some sort of ID number for each item, and use that for the value of the radio button. Then in form.php use the ID number you receive to find out what item they chose and its price.

You shouldn't rely on the customer to tell you how much the items cost!

Weed has a great point. User input should always be determined by your script, the reason is because it could cause a possible exploit, especially if you are using an sql database. Using an index will help this issue out since your script holds hard coded options instead of allowing the user to change the inputs.
