help you fix your problem You are sending you're POST to configuration.php not to your executer?
code :
<form class="form-horizontal" method="post" action="configuration.php" data-validate="parsley">
$requestID = $_GET['id'];
$requestID = (isset($_GET['id'])) ? $_GET['id'] : 'add ID for POST';

Why do I keep getting an undefined index error even though var_dump() shows the index is defined?

This might help you Omar's answer is correct. For more detail, look at the documentation of fetchAll: PHP docs for fetchAll
The skinny is that fetchAll returns an indexed array of all rows from your query, and each if those indexed arrays contains an associative array of keys and values. As a result, the data you want is stored in $studentFunds[0]['studentFunds']
code :
$oldAmount = 0;
if( is_array( $studentFunds ) && count( $studentFunds ) == 1 )
{
   $oldAmount = $studentFunds[0]['studentFunds'];
}

this will help Undefined index: logout in F:\xampp\htdocs\xxx\index.php on line 6 This is the index. , i suggestion to you, first create a function ex:
code :
<?php
function get_request($name, $default = ''){
    if(isset($_REQUEST[$name])){
        if($_REQUEST[$name] != ''){
            return $_REQUEST[$name];
        }else{
            return $default
        }
    }else{
        return $default
    }
}
?>
<?php
session_start();
date_default_timezone_set('Europe/Paris'); 

// LOGOUT
if(get_request('logout', 0) == 1)
// LOGOUT
if(isset($_GET['logout']) && $_GET['logout'] == 1)

I wish this helpful for you Always make use of the isset construct (whether a value is assigned to your variable or not) to check for the variables before assigning data.
code :
if(isset($_POST['jenis_kelamin']))
{
$_POST['jenis_kelamin']= strtoupper($data['siswa']['jenis_kelamin']);
}
$siswa=array('id'=>$id,'nama'=>$this->input->post('nama'),
                        'alamat'=>$this->input->post('alamat'),
                        'jenis_kelamin'=>$this->input->post('jenis_kelamin'),
                        'tanggal_lahir'=>date('Y-m-d', strtotime($this->input->post('tanggal_lahir'))));

I hope this helps you . Firstly, you have no valid enctype in your form to handle files, so add it; it's required.
code :
<form action='inc/download_attachment.php' method='post' enctype='multipart/form-data'>
if (

    !empty($_FILES['attachment']) 
    && $_FILES['attachment']['size'] == 0 


) {

// do something

}
<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Then the rest of your code

I wish this helpful for you You are mixing PDO with mysql and there are multiple syntax errors. Your code should be like this:
code :
<?php
error_reporting(E_ALL);
$submit = $_POST['submit'];
if($submit) {
   $name = $_POST['somename'];
   $username = $_POST['username'];
   $con = new PDO('mysql:host='.$db_hostname.';dbname='.$db_database.';charset=utf8mb4', $db_termname,$db_password, array(PDO::ATTR_EMULATE_PREPARES => false,PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
   $stmt = $con->prepare('SELECT * FROM users WHERE username=:username');
   $stmt->bindParam(":username", $username);
   $stmt->execute();
   $row = $stmt->fetch(PDO::FETCH_ASSOC);
   if($name=='ip') {                       
      echo $row['ip'];  
   }elseif
      ($name=='uid') {
         echo $row['uid];
      }
}
?>

<form action="" method="POST">
  <input type="radio" name="somename" value="ip">IP<br>
  <input type="radio" name="somename" value="uid">UID<br>
  Enter Name: <input type="text" name="username">
  <br>
  <input type="submit" name="submit">
</form>
if($name=='ip') {  
   if($row['ip'] == 'ip') {
      echo 'Result!';
   }else{ 
      echo 'No Result!';
   }
}

if($name=='uid') {  
   if($row['uid'] == 'uid') {
      echo 'Result!';
   }else{ 
      echo 'No Result!';
   }
}
