Hi,
I need a condition in update form where before the form is updated, I have
to check if the value of a cell is empty or not. If it is not empty, an
error is shown and if empty, it is updated.
What I am doing wrong in the script ( $_POST['helper1_pos'] gets value from
the form). It shows error even if the cell is empty.
if (!is_null($_POST['helper1_pos'])) {
echo "Sorry! Helper 1 position already volunteered.";
exit;
}
else {
//update
}
Thanks.
Ashok.
