What should I do if i want this button can be only clicked by admin

I have done some researches but i cant find a proper answer

I want that button can only be clicked by admin, if that button clicked my a normal user an alert box will appeared

Or perhaps that button will only appeared if logged in as admin?

<a href="view.php" class="btn btn-info" role="button">Admin button</a>

This is my admin button ↑

My admin information from my database is:

userid: 3
username: admin
password: admin
role: 0

Should I include ↓

<?php
session_start()
include "connection.php"

if(empty($_SESSION['role'] == '0')){
echo "xxx";
}
else
{
echo "xxx";
}
?>

If so, what should i write within the "xxx"?

The connection.php will be:

<?php
$conn = mysqli_connect("localhost","root","","gallery");

if(mysqli_connect_errno())
{
    die("<script>alert('Error in connection !');window.history.go(-1);</script>");
}
echo "<script>alert('Successfully connected !');</script>";
?>

You can use session variable "role" and javascript function to do that.

Javascript:

Add this script in your head or footer

<script type="text/javascript">
function checkUser(type) {
    if (type == '0') { // User is Admin move to view
        window.location("view.php");
    } else {
        alert("Hey! You are not admin");
    }
}
</script>

HTML

In your page change your link to button as:

<?php
session_start();
include "connection.php" ?>

<button class='btn btn-info' role='button' onclick="checkUser(<?php if($_SESSION['role'] == '0'){
  echo '0';
  } else {
    echo '1';
  } ?>

);" >Admin button</button>

<?php
session_start()
include "connection.php"

if(empty($_SESSION['role'])
&& $_SESSION['role'] == '0'){
    echo "<p><a href='view.php' class='btn btn-info' role='button'>Admin button</a></p>";
}
?>

It should be like above condition.

In your code, empty function and equality condition is not correct.

If your only intentions are to hide the button for non-admin users then its very simple, and you don't need an else logic operator for this. Since if the condition isn't met. Don't do anything

<?php
session_start()
include "connection.php"

if(empty($_SESSION['role'] == '0')){
echo "<p><a href='view.php' class='btn btn-info' role='button'>Admin button</a></p>";
}
?>
