How to unset $_POST, if page gets reloaded it does not re-send

[cs.punk]

What I am trying to do is UNSET the $_POST so that the if statement returns false... But it seems the browser just 're-sends' the $_POST arrays...

 

if (isset($_POST['apr_ad']) && $_POST['apr_ad'] == "Approve Ad"
    && isset($_POST['aa_id']) && $_POST['aa_id'] == "$adid"
&& isset($set))
{$con = mysqli_connect ("$dbhost","$dbuser","$dbpass","$dbname")
     or die ("Could not connect to server");

  $sac = "SELECT * FROM board_posts WHERE ad_id = '$adid'";
  $e_sac = mysqli_query($con,$sac)
            or die ("Could not execute \"SELECT * FROM board_posts WHERE ad_id = '...'\" query."
		. mysql_error());
  $row = mysqli_fetch_assoc($e_sac);
   
  $copy = "INSERT INTO ad_posts (cat_id, datetime, ad_title, ad, ad_id)
  		  VALUES ('{$row[cat_id]}','{$row[date]}','{$row[ad_title]}','{$row[ad]}','{$row[ad_id]}')";
  $e_copy = mysqli_query($con,$copy)
            or die ("Could not execute \"INSERT INTO ad_posts (...) VALUES (...)\" query."
		. mysql_error());

  $delete = "DELETE FROM board_posts WHERE ad_id = '$adid'";
  $e_delete = mysqli_query($con,$delete)
              or die ("Could not execute \"DELETE * FROM board_posts WHERE ad_id = '...'\" query."
		  . mysql_error());
  echo "<p class=\"smallheading\">Ad has sucsessfuly been approved.</p>";
  unset ($_POST['aa_id']);
  unset($_POST);
  unset ($set);
}

I got what I wanted like this :

 

<?php

if (isset($_POST['apr_ad']) && $_POST['apr_ad'] == "Approve Ad"
    && isset($_POST['aa_id']) && $_POST['aa_id'] == "$adid")
{$con = mysqli_connect ("$dbhost","$dbuser","$dbpass","$dbname")
     or die ("Could not connect to server");

  $sac = "SELECT * FROM board_posts WHERE ad_id = '$adid'";
  $e_sac = mysqli_query($con,$sac)
            or die ("Could not execute \"SELECT * FROM board_posts WHERE ad_id = '...'\" query."
		. mysql_error());
  $row = mysqli_fetch_assoc($e_sac);
  
  if ($adid == $row[ad_id])
   {$copy = "INSERT INTO ad_posts (cat_id, datetime, ad_title, ad, ad_id)
  		     VALUES ('{$row[cat_id]}','{$row[date]}','{$row[ad_title]}','{$row[ad]}','{$row[ad_id]}')";
    $e_copy = mysqli_query($con,$copy)
              or die ("Could not execute \"INSERT INTO ad_posts (...) VALUES (...)\" query."
		  . mysql_error());

    $delete = "DELETE FROM board_posts WHERE ad_id = '$adid'";
    $e_delete = mysqli_query($con,$delete)
                or die ("Could not execute \"DELETE * FROM board_posts WHERE ad_id = '...'\" query."
  		    . mysql_error());
    echo "<p class=\"smallheading\">Ad has sucsessfuly been approved.</p>";
    unset ($_POST['aa_id']);
    unset($_POST);
    unset ($set);
   }
  else
   {echo "<p class=\"paragraph\">Sorry but this ad does not exsist, it might have already been     		          approved !</p>";
   }
}
