passing a variable to another page while redirecting in php

Question

I want to set a button that when I click on that it goes to another page.

below is my code:

if(sizeof($errors) > 0)
     {
       foreach($errors as $err)
       {
         echo "<script type='text/javascript'>alert('$err');</script>";
       }
     }
     else
     {
       echo "<script type='text/javascript'>alert('finish');</script>";
       $newURL = "additional_info_sodur_card?id=" + $_GET['id'];
       header('Location: $newURL');

     }

Everything is OK and even to assure that it enters the else part I have written an alert which works. The problem is that for header part it gives me an error like this: Cannot modify header information - headers already sent by ... how can I solve this problem? Can I use javascript with windows.location.href or other ways to be redirected to another page? thanks for your response in advance

you can use sesssion or you have to pass status to newURL page — Madhawa Priyashantha, Jun 18 '17 at 12:24
In your else block, comment out the echo line and see what happens — Dale, Jun 18 '17 at 12:24
The shown error already tells you what to do.. you've got output before a header — Jeff, Jun 18 '17 at 12:29

I just found something about doing this: if (headers_sent()) { die("Redirect failed. Please click on this link: click"); } else{ exit(header("Location: ".$newURL)); } It worked but I don't want the user to click on it to go to another page. I want the link to be self-clicked — saeed doozandeh, Jun 18 '17 at 12:55

I prefer to use JS redirect instead to avoid this.

?>
  <script language="javascript" type="text/javascript">
    alert('Your alert.');

    window.location = 'redirect_url';
  </script>
<?php

Hope this helps.
