reading from a form

PHP Code:


		
			
if(!isset($_POST[$sd_Burning])) {

  $sd_Burning = "";

  } else {

    $sd_Burning = $_POST[$sd_Burning];

}

PHP Code:


		
			
<input type="checkbox" name="sd_Burning" /> Burning

This is the code im using when my form is submitted. All should but doing is checking if the checkbox sd_Burning is checked or not. But it does nothing. the second is my checkbox in the form.

Any ideas what im doin wrong here?

well im no expert but i think the problem is the double $, it should be:

$_POST[sd_Burning]

also make sure your form method is set to post.

You're using $sd_Burning to index the $_POST array, so it depends on the value stored in that variable.

You probably mean't to use:

PHP Code:


		
			
$_POST['sd_Burning']

Also, you need to have a value stored in the checkbox by using the html attribute value. Thus, the $sd_Win_Burning will actually have a value if it is set via the form.

ye it was the second $. Thx guys.. And for checkboxes you dont have to set a value cause it comes back as either "on" or "off" but other fields i think you are correct Andrew.
