        <div class="card-body" style="background: #f5f5f5;">
            <button class="btn btn-primary btn-sm" type="submit" name="contactsend">Save&nbsp;Settings</button>
        </div>
    </div>
</form>

But if i try to contact it in my php file

if(isset($_POST['contactsend'])) {
  $inaddress = mysqli_real_escape_string($db, $_POST['address']);
  $incity = mysqli_real_escape_string($db, $_POST['city']);
  $insert = $db->query("UPDATE accounts SET address = ".$inaddress.", city = ". $incity ." WHERE id = ".$id_user."");
}

it wont get the contactsend button if i press it, so it also wont update the tables. can someone please help me?

Answer 1

that form is posting to it's own page... is the php script in the same file as the render script? If not you need to set the action="" attribute of the form to the php script url
