I am trying to display the errors on the same page if anyone entered invalid login details but when invalid login details are entered a message is displayed called Array? Not sure why that's happening.
In this code, there is a login form and if user logs in then log in, a success message appears but when details are invalid a message should appear "invalid details" which is not appearing
<?php
// starting session
session_start();
// calling connection
require('/home/s3022041/sqlC/dbConnect.php');
$message = "";
$role = "";
if($_SERVER['REQUEST_METHOD'] == "POST"){
//Array to hold any errors in updated data
$errors = array();
//Checking entered email
if(empty($_POST['username'])){
$errors[] = "username address required";
}
else{
$username = $_POST['username'];
if(filter_var($_POST['username'], FILTER_VALIDATE_EMAIL)) {
$username = $_POST['username'];
}
else {
$errors[] = "Invalid username";
}
}
if(empty($_POST['password'])){
$errors[] = "passwrod required";
}
else{
$password = validating_input($_POST['password']);
}
if(isset($_POST["btnLogin"]))
{
$username = $_POST["username"];
$password = $_POST["password"];
// retrieving user data
$query = "SELECT * FROM user WHERE username = '$username' AND password='$password'";
// executing query
$result = mysqli_query($connection, $query);
if(mysqli_num_rows($result) > 0)
{
while($row = mysqli_fetch_assoc($result))
{
// if user logs in
if($row["role"] == "user") //|| ($row["role"] == "admin"))
{
//Creating session variables to hold relevant information about who is logged in
$_SESSION['User'] = $row["username"];
