POST unchecked checkboxes with hidden elements

I know there are other posts with the same question but it doesn't work for me. Well, I have a database table (image) with 'img_name' and 'img_status'. Status can be 'active' or 'inactive'. In php I do following: $images = mysqli_query($con, "SELECT * FROM images");

                while($row = mysqli_fetch_object($images)) {
                    if ($row->img_status == 'active') {
                        echo '<label><input type="checkbox" name="image[]" value="' . $row->img_name . '" checked> ' . $row->img_name . '</label>';
                    } else {
                        echo '<label><input type="checkbox" name="image[]" value="' . $row->img_name . '"> ' . $row->img_name . '</label>';
                    }
                }
