Merhaba arkadaşlar, mysql 'e canlı destek, analytics vs kod eklemek istiyorum. Ama post edince 403 hatası veriyor.
strip_tags, htmlspacial.. vs denedim ama hep 403 hatası veriyor. Bunu eklemenin yolu nedir?

<?php

                $api = $db->from('api')->first();

                if(isset($_POST["update"]))
                {
                    $delete = $db->delete('api')->done();
                    $update = $db->insert('api')
                        ->set(array(
                        'google_analytics' => html($_POST["google_analytics"]),
                        'yandex_metrica' => html($_POST["yandex_metrica"]),
                        'canli_destek' => html($_POST["canli_destek"]),
                        'whatsapp' => html($_POST["whatsapp"]),
                              ));

                    if ($update)
                    {
                        swal("success");
                    }

                }

                ?>

<form class="form-horizontal" method="post" action="">
