I am trying to submit this form and upon the submission it should redirect to itself back. However, the problem I am facing is that, after I submit the form it display this error:
Notice: Undefined index: id in C:\xampp\htdocs\iNetLink\configuration.php on line 9
Here is my form file:
<?php include("header.php");
if(ISSET($_POST['node'])){
$nodeID = $_POST['node'];
}else{
$nodeID = 0;
}
$requestID = $_GET['id'];
$qConfigurationForm = "SELECT * FROM configuration WHERE request_id = '$requestID' ";
$rConfigurationForm = $connection->query($qConfigurationForm);
$rowCount = $rConfigurationForm->rowCount();
$row = $rConfigurationForm->fetch();
if($rowCount > 0){

Help! :)

Answer 1

You are sending you're POST to configuration.php not to your executer?
<form class="form-horizontal" method="post" action="configuration.php" data-validate="parsley">
Also...
$requestID = $_GET['id'];
this will error because $_GET['id'] is not available during POST. to fix your code try this:
$requestID = (isset($_GET['id'])) ? $_GET['id'] : 'add ID for POST';
or make sure your form is sending in the right PHP file
