Radio Button Validation HTML FORM

Question

I have this form:

<form name="form" action="order.php" method="post">
Please select Amount:<br />
<input type="radio" name="amount" value="25" id="25" /> <label for="25">$25</label><br />
<input type="radio" name="amount" value="50" id="50" /> <label for="50">$50</label><br />
<input type="radio" name="amount" value="75" id="75" /> <label for="75">$75</label><br />
<input type="radio" name="amount" value="100" id="100" /> <label for="100">$100</label><br />
<input type="radio" name="amount" value="200" id="200" /> <label for="200">$200</label><br />
<input type="submit" value="Submit">
</form>

I am wondering how I can do validate to make sure that one of these Radio Button's are selected?

I have tried a few different things, I have looked on Google and visited almost every site on the first and second pages and could not get it working..

Thanks,
Chad.

which language do you want to use for the validation? PHP? Java? Javascript? (not real validation in this case) — Leo supports Monica Cellio, Feb 07 '13 at 02:20

One solution without using client-side scripting would be to select one by default using CHECKED:

<input type="radio" name="amount" value="25" id="25" CHECKED />

Here is a fiddle to show you.

If this won't work for your situation, look into using jQuery or Javascript to implement a solution.

This should help get you started: How can I check whether a radio button is selected with JavaScript?

Good luck.
