Good day to all of you. As the title says I need help about facebox when updating a data(s).

Here's the code for the button to show the facebox

HTML Code:
<a  rel="facebox" href="../admin/c_status.php?id='.$row["userID"].'">Edit</a>
and here's the code inside facebox

PHP Code:
<?php
    
include("../db/dbCon.php");
    
//$id = $_GET['id'];
    //echo $id;
?>

Status
<form method="post">
    <select name="selActive" id ="selActive">
        <option value="ACTIVE">ACTIVE</option>
        <option value="IN-ACTIVE">IN-ACTIVE</option>
        <option value="GRADUATE">GRADUATE</option>
    </select>
    <br>
    <br>

    <button class="btn btn-success btn-block btn-large" name="saveChangeButton" id ="saveChangeButton">Save Changes</button>
</form>

<?php
    
if(isset($_POST['saveChangeButton'])){
        
$id $_GET['id'];
        
$status $_POST['selActive'];
        
        
$cStatus $conn->prepare("UPDATE useraccount SET status = :status WHERE userID = :userID");
        
$cStatus->bindParam(':status'$status);
        
$cStatus->bindParam(':userID'$id);
        
$cStatus->execute();
    }
?>
The problem I encounter is the data won't update via clicking the edit button BUT when I edit via address bar like "http://localhost/ict/admin/c_status.php". It will work.
