Session if statement working on one page but not the other - php

Question

Before we start, I'm a beginner. I'm sure it's a simple solution but just not for me.
I'm using a session so no one can't access an admin page unless they're an admin.
The code is:
if ( $_SESSION['admin'] != 1 ) {
$_SESSION['message'] = "You're not admin!";
header("location: ../error.php");
}
Which works perfectly. regular users can't access it but admins can. BUT.
In my main cpanel I want to have a button linking to the admin panel that will only appear if the user is admin. I did the same piece of code:
if ( $_SESSION['admin'] != 1 ) {
echo '<button class="butto button-bloc" name="admin"/>Admin Panel</button>';
}
Problem is, it seems like the button shows up whether the user is an admin or not and now I think that my code is just trying to make me blow my lid as I spent a full hour trying to find what the f-- is on the go.
Any help would be greatly appreciated! I'm sure someone who's good with PHP will have it solved in under a minute lol

Answer 1

The condition you have written is same for user who is admin and not an admin
Please check the condition
For having a button linking to the admin panel that will only appear if the user is admin.
if ( $_SESSION['admin'] == 1 ) { // you have written $_SESSION['admin'] != 1
echo '<button class="butto button-bloc" name="admin"/>Admin Panel</button>';
}

Answer 2

You can use
if (isset($_SESSION['admin']) && ($_SESSION['admin'] == 1 )) {
echo '<button class="butto button-bloc" name="admin"/>Admin Panel</button>';
}
This way the button will show when you set the $_SESSION['admin'] and if it is TRUE (i.e. 1).

Answer 3

Try This:
if (isset($_SESSION['admin']) {
if ( ($_SESSION['admin'] == 1) ) {
echo '<button class="butto button-bloc" name="admin"/>Admin Panel</button>';
}
}
