[RESOLVED] Value Checking

[obrienkev]

Hi all,

I have a select menu generated using PHP.
One option is to have a value of 0...

echo '<option value="0">Select Course</option>';

Then the following code is to check what option is selected...

if($course == 0)
{
   echo '<p>Please select a course</p>';
	 echo '<p><a href="javascript:history.back(1)">Return</a></p>';
	 exit;
}

My problem is I can't get the checking working correctly. Any ideas how to fix this?

Thanks.

Kevin.

Hi,

See my other post: How is the variable to be set? Where do you get the values from the posted data?

if that is done properly, I think it has to do with the fact that 0 and 1 also go as true and false. Try using three = signs.

Or.. solve it by testing again -1, and make -1 your default not filled out.

if($_POST['course'] == 0)

Thanks guys.

echo '<option value="0">Select location</option>';

// declare variables
$location = $_POST['location'];

// check field completed
if($location == "0")
{
   echo '<p>Please select a location</p>';
	 echo '<p><a href="javascript:history.back(1)">Return</a></p>';
	 exit;
