Answer 1

you missed the closing brace } of if condition

 <script>
 var r = confirm("Are you sure?");
 if (r == true)
 {
 alert(' item successfuly deleted!!');
 }
 </script>

FIDDLE

Answer 2

Try a short if statement

(r == true) ? alert('item successfuly deleted!!') : "" ;

Answer 3

You have to remove the script tags before php tags start. Update the code as below:-

       <?php
       require_once('connect/connect.php');
       ?>
     <script>
    var r = confirm("Are you sure?");
    if (r == true)
     {
       alert(' item successfuly deleted!!');

       <?php

       if(isset($_GET['pid'])){
       $sql ='Select * FROM product where pid = '.$_GET['pid'];
       $qry = mysql_query($sql);
       $data = mysql_fetch_array($qry);
       $pname = $data['pname'];
       $pstock = $data['pstock'];
       }
       $sq3="INSERT INTO report VALUES('NULL','".$pname."', '" .$pstock. "','Item Deleted' )";
        $qry3 = mysql_query($sq3);

        $sql2 = 'DELETE FROM product where pid = '.$_GET['pid'];
        $qry2 = mysql_query($sql2);
        ?>

         window.location.assign('products.php');    
        }

       else
       {
         window.location.assign('products.php');
        }
      </script>

Try this and confirm.
