There's the problem. $cdate = '' should be $cdate == ''Code: Select all
if($name == '' || $nummer == '' || $cdate = '' || $stuck == ''){
Code: Select all
<?php
//connect
include ("db/connect.php");
//create new/edit
function renderForm($nameS = '', $nummerS = '', $dateS='', $stuckS='', $error='',$id=''){
$cdate = date(' Y-m-d H:i:s');
