PHP Notice: Undefined index

I am getting a PHP notice for undefined index on the line that corresponds to the conditional where $_POST["address"] != ""

if ($_SERVER["REQUEST_METHOD"] == "POST") { $name = trim(filter_input(INPUT_POST, "name", FILTER_SANITIZE_STRING)); $email = trim(filter_input(INPUT_POST, "email", FILTER_SANITIZE_EMAIL)); // checks if the email has a value $details = trim(filter_input(INPUT_POST, "details", FILTER_SANITIZE_SPECIAL_CHARS));

if ($name == "" || $email == "" || $details == "") {

    echo "Please fill in the required fields: Name, Email and Details";
    exit;
}

if ($_POST["address"] != "") {
  echo "Bad form input";
  exit;
}

Hi,

maybe try this :) i used empty() function instead of your solutions.

if ($SERVER["REQUEST_METHOD"] == "POST") { 
    $name = trim(filter_input(INPUT_POST, "name", FILTER_SANITIZE_STRING)); 
    $email = trim(filter_input(INPUT_POST, "email", FILTERSANITIZE_EMAIL)); 
    // checks if the email has a value 
    $details = trim(filter_input(INPUT_POST, "details", FILTER_SANITIZE_SPECIAL_CHARS));

if (empty($name) || empty($email) || empty($details)) {
    echo "Please fill in the required fields: Name, Email and Details";
    exit;
}
$address = $_POST["address"];
if (!empty($address)) {
  echo "Bad form input";
  exit;
}
