Hey.

So, basically, you allow the user to select from only one of the <select> boxes, and you need the value of that box to be inserted into the database?

If so, you would simply have to go through the boxes, one by one, and check if they have a value. Like:

<?php
$value = null;
if(isset($_POST['select1']) && !empty($_POST['select1'])) {
    $value = $_POST['select1'];
}
else if(isset($_POST['select2']) && !empty($_POST['select2'])) {
    $value = $_POST['select2'];
}
else ( // {
    // A box was not submited.
    echo "Please select something!";
}
 
if($value == null) { // !
    // Insert the value into a database
}
?>
