I have a html navbar code and I need to convert it to php when logging in a user shows him custom navebar and when the administrator logs in, he sees his own page




for admin

<div class="navbar">
<a href="index.html">home</a>
<a href="about.html">about us</a>
<a href="brand.html">brand</a>
<a href="portfilo.html">porfile</a>
<a href="admin_page.php">control panel</a>
<div class="navbar-right">
<a href="signup.php">Sign Up</a>
<a href="login.php">Login</a>
</div>
</div> 

for user

<div class="navbar">
<a href="index.html">home</a>
<a href="about.html">about us</a>
<a href="brand.html">brand</a>
<a href="portfilo.html">porfile</a>
<a href="user_page.php">user page</a>
<div class="navbar-right">
<a href="signup.php">Sign Up</a>
<a href="login.php">Login</a>
</div>
</div> 

What I have tried:

I tried a lot with php but I'm not a pro at it

I use this code to log in

<?php

@include 'config.php';

session_start();

if(isset($_POST['submit'])){

   $name = mysqli_real_escape_string($conn, $_POST['name']);
   $email = mysqli_real_escape_string($conn, $_POST['email']);
   $pass = md5($_POST['password']);
   $cpass = md5($_POST['cpassword']);
   $user_type = $_POST['user_type'];

   $select = " SELECT * FROM user_form WHERE email = '$email' && password = '$pass' ";

   $result = mysqli_query($conn, $select);

   if(mysqli_num_rows($result) > 0){

      $row = mysqli_fetch_array($result);

      if($row['user_type'] == 'admin'){

         $_SESSION['admin_name'] = $row['name'];
         header('location:admin_page.php');

      }elseif($row['user_type'] == 'user'){

         $_SESSION['user_name'] = $row['name'];
         header('location:user_page.php');

      }
     
   }else{
      $error[] = 'incorrect email or password!';
   }

};
?>
