Does this prevent sql injection in anyway?

[Abel1216]

Based on the comments on my previous question, took some tutorials on how to avoid injections on query. Does the code below prevents against it in any way.? Secondly, can you recommend a good article that writes well in how to secure input data by users. Please be kind with your comments.😉😉. Thankks in advance.

The code works fine.
 

<?php 

include 'db.php';

error_reporting(E_ALL | E_WARNING | E_NOTICE);

ini_set('display_errors', TRUE);

 if(isset($_POST['submit']))

 {
    
 $username = $_POST['username']; 
$password =  ($_POST['password']); 

$sql = "SELECT * FROM customer WHERE username = ?";
$stmt = $connection->prepare($sql); 
$stmt->bind_param('s', $username);
$stmt->execute();
$result = $stmt->get_result();
$count =  $result->num_rows;
   if($count == 1) 
                         {
while ($row = $result->fetch_assoc())
 {
    if ($row['status'] == 'blocked')

 {

 echo'your account is suspended'


   session_destroy();

   exit();

  }

 else if($row['status'] == 'active')
{

if($username !== $row['username']) 

 { 
echo '<script>swal.fire("ERROR!!", " Username is not correct. Check Again", "error");</script>';
} 
if($password !== $row['password']) 
{
  echo'<script>swal.fire("ERROR!!!", "Your Password is Incorrect. Check Again.", "error");</script>';       
}
if($username == $row['username'] && $password == $row['password']) 
{ 
header('Location:cpanel/');
else
{
}
}//if count
}//while loop
}//submit
?>

You are safe against SQL injection.

Now the problem you have to solve is that you're storing plain passwords in your database. That's super bad. Fix it.
