将用户重定向到php中的新窗口

Question

I have a authentication device that on successful transaction returns only ok. If the output is anything else but ok, it won't work and throw error.

On successful transaction it's redirected to page cams-attendance.php which returns the value ok.

<?php
echo 'ok';
?>

I want to redirect the user to a another page in a new window. I tried header, but header cannot redirect to a new window. I've tried javascript. But as it's more than ok, I'm getting error.

<?php
echo 'ok';
?>
<script type="text/javascript" language="Javascript">window.open('http://www.example.com');</script>

using this code, the output is -

ok
<script type="text/javascript" language="Javascript">window.open('http://www.example.com');</script>

So, as it's printing more than ok, the device is throwing error.

How can I achieve this.

Answer 1

I assume that your final variable is $resp and I have assigned the value "ok" to it. Here I check to see whether the $resp is equal to "ok" and if there is a match I echo out the javascript which pops up the new website on page load.

<?php $resp = "ok";
 if($resp=="ok"){
?>
<script>
   window.onload = function() {
      window.open('http://www.example.com');
   };
</script>
<?php } ?>
