Simple Radio Buttons

ComputerChip

I have given up trying to get radio buttons to execute sql queries.
It would be really great if someone would post an html page and php script that will show you a page with 3 radio buttons(using an array) and when submitted it will echo that value.
I have cut and pasted so many different scripts but they all have something different. Some need multiple checkboxes where others want to send an email and some want to pull data from a database. All I would like to see is the values.
Thanks

<form action="" method="post">
one <input type="radio" name="test" value="one"><br>
two <input type="radio" name="test" value="two"><br>
three <input type="radio" name="test" value="three"><br>
<input type="submit" value="test" name="submit">
</form>

<?
if (isset($_POST['submit'])) {
	echo $_POST['test'];
	}

?>

I couldn't get yours to work. I was getting a T_VARIABLE parse error. I forgot to mention I am using PHP 4 and Global Var =on But it helped me figure out my original codes problem.
Your code:

<input type="submit" value="test" name="submit">

My code:

<input type="submit" value="submit"  name="submit">

But now as always this brought up another question.
Why does the output bring up a large black dot before my output.
Does it have something to do with putting a . before the $POST.
If not what does the .(dot) mean before a $POST

Thanks for the script before. I am a real newbie. Some of these newbies on here seem to me should have graduated.

Sound like the reason you're getting an error is because you are trying to output the variable without stepping through the array.

Using the form fields above, the output code would look like this:

$arraynum = count ($POST["test"]);
for ($i=0;$i<$arraynum;$i++)
{
echo $POST["test"][$i];
}

swoolf:

The point in using radio button groups is that they only allow a single member of the group to be selected. So you only receive $_POST['test'] as a string, NOT an array.

ComputerChip:

If you post your full code (posted between [ PHP ] and [ /PHP ] tags) I will have a look.

If you had pasted the code from my previous post into a file without any changes it would work fine on PHP=>4.1, if PHP<4.1 you would have to change $_POST to $HTTP_POST_VARS.

Even coding with globals on (bad habit, don't do it) you should use the request arrays instead of the globalized vars.
