php checkbox form validation

Here is my issue, No matter what I select, yes or no, it always displays the same response. In this case it alwayhs displays the error.

I have also used a checkbox and that does not work. I see that is what is used for the checkbox on this forum, can someone send me that code or something?

any ideas

if($t27=="1"){
echo "<script language=Javascript>alert('Thank You for Agreeing to Terms & Conditions');</script>";
// ... checkbox1 has been checked, form processing code here
} else {
echo "<script language=Javascript>alert('Error! You must agree to the terms and conditions!');history.back(-1);</script>"; // ... checkbox1 has NOT been checked, form processing code here
}

This is the html part of the form

<select name="t27" id="t27">
<option value="1">Yes</option>
<option value="0" selected="selected">No</option>
</select>

Thanks

Are registered globals turned on? If they are, then it should be passing the value, otherwise, you may need to use $_POST['t27'], $_GET['t27'], or $_SERVER['t27'].

I can't remember if

doesn't need the selected=" " part. It may just need selected there. And if you are using radio buttons, it should just be "checked" without quotes.

 

ok, $_POST['tsomenumber'] for others where being used. This was not originally my script, I tried adding that $_POST['t27'] before, but for some reason is was still being though of as not filled. If I required it, the error message would also pop up saying that all the required forms where filed.

hmm, odd, but it works now. - thats exactly what i did before, well, I did not give the checbox a value=1 before, maybe thats it. hmm, thanks for your help.
