向if / else函数添加2个需求

Question

<?php
  session_start();
  if(!isset($_SESSION['myusername']) and ($_SESSION['recht']!=30){
      echo  ("<SCRIPT LANGUAGE='JavaScript'>
      window.alert('U bent niet bevoegt voor deze applicatie')
      window.location.href='../home.php'
      </SCRIPT>");
  }
  else {
      //Echo the page
  }
?>

I want to make a page secure by using the following requirements: You must have filled the $_SESSION['myusername'] and You can only login when $_SESSION['recht'] is equal to 30.

I can't get this to work. I would really appreciate if you could help me.

Answer 1

if(!isset($_SESSION['myusername']) or $_SESSION['recht']!=30) {

....

}

You have forgotten the closing ) / Have openend one you didn't need. It should work like this.

And you need to terminate your javascript lines:

window.alert('U bent niet bevoegt voor deze applicatie');
window.location.href='http://www.domain.com/home.php';

Since html5 you can use

 <script></script>

instead of

<script language='JavaScript'></script>

as javascript is default for the script tag now.
