I then submit my page and on the following page I put the posted value into
two variables.
$comments = strtoupper($_POST['comments']);
$check_comments = $_POST['comments'];
I made two variables for the same posted value because I believe empty()
does not work with strtoupper in front of the value. It only works with a
standalone variable, correct?
So, once I have assigned my comments to a variable I am doing:
if(!empty($check_comments)) {
echo "Do Something";
}
Try:
$comments = isset($_POST['comments']) ? $_POST['comments'] : null;
if ($comment == null)
{
echo 'do something';
}
else
{
echo 'do something else';
}
Cheers,
tedd
