I want to allow if account_type = 1 or 2

This is my code now but it doesent work.

PHP Code:

<?php
if($_SESSION["account_type"] !== "1" || !== "2") {
 
}
?>

You want:

if( ($_SESSION["account_type"] == 1) || ($_SESSION["account_type"] == 2) ) {

A few points:
1) You need to do each comparison completely (as opposed to the "if value equals 1 or 2" you need to do "if value equals 1 or value equals 2").
2) When comparing with numbers, don't put the numbers in quotes. You are comparing to a string that represents a number... normally this works, but not always.
3) !== is "NOT equals" not "equals" which is what you really wanted.
4) Using the '!==' and '===' operators compares types, too, which is really not what you want here... hence you would use '!=' or '==' instead.

Try && instead of ||

PHP Code:

 <?php
if($_SESSION["account_type"] == "1" || == "2") {
    echo "Not a valid account type.";
}
?>

Removed the ! which mean is not identical

Here is about five different ways I could think of to test this argument...

PHP Code:

if ($_SESSION['account_type'] == 1 OR $_SESSION['account_type'] == 2) . . .
 
if ($_SESSION['account_type'] > 0 OR $_SESSION['account_type'] < 3) . . .
 
if (in_array($_SESSION['account_type'], array(1, 2))) . . .
 
if (abs((int)$_SESSION['account_type']) AND (int)$_SESSION['account_type'] <= 2) . . .
 
if (floor($_SESSION['account_type']) AND abs(inval($_SESSION['account_type'])) < 3) . . .

Using && instead of || would mean that both sides would have to be true. Meaning $_SESSION['account_type'] would have to equal 1 and also equal 2. This could never happen because if a variable equals 1 than it cannot equal 2 and vice versa.
