Hello,

I'm using this code for my login system and was wondering if anyone can help me add an admin link if a user logs in as admin using a status field then it will show Admin link and if they login as a user if will disable link if will need to show on the Dashboard Page.

Register.php

Code: Select all
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Registration</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<?php
require('db.php');
// If form submitted, insert values into the database.
if (isset($_REQUEST['username'])){
        // removes backslashes
   $username = stripslashes($_REQUEST['username']);
        //escapes special characters in a string
   $username = mysqli_real_escape_string($con,$username);
   $email = stripslashes($_REQUEST['email']);
   $email = mysqli_real_escape_string($con,$email);
   $password = stripslashes($_REQUEST['password']);
   $password = mysqli_real_escape_string($con,$password);
   $trn_date = date("Y-m-d H:i:s");
        $query = "INSERT into `users` (username, password, email, trn_date)
VALUES ('$username', '".md5($password)."', '$email', '$trn_date')";
        $result = mysqli_query($con,$query);
        if($result){
            echo "<div class='form'>
<h3>You are registered successfully.</h3>
<br/>Click here to <a href='login.php'>Login</a></div>";
        }
    }else{
?>
<div class="form">
<h1>Registration</h1>
<form name="registration" action="" method="post">

   $result = mysqli_query($con,$query) or die(mysql_error());
   $rows = mysqli_num_rows($result);
        if($rows==1){
       $_SESSION['username'] = $username;
            // Redirect user to index.php
       header("Location: index.php");
         }else{
   echo "<div class='form'>
<h3>Username/password is incorrect.</h3>
<br/>Click here to <a href='login.php'>Login</a></div>";
   }
    }else{
