CSV Post reload - php

Question

hallo guys sorry for bothering ..the code is now working..i had so many problems on my previous posts but this is the last problems i am getting..i noticed when i insert the csv file it correctly inserting..but if i refresh the page data is being duplicated due to post data..how do i make this not to repeat? i am trying to paste this but i get an error
SAVED_REQUEST = $_REQEUST;
$SAVED_POST = $_POST;
$SAVED_GET = $_GET;
// FINALLY, IN YOUR LAST LINE ERASE THE PROBLEM VARIABLES...
$_REQUEST = $_POST = $_GET = NULL;
<?php $_REQUEST = $_POST = $_GET = NULL; ?>
this is my previous script
<form enctype="multipart/form-data" method="POST" action="" >
CSV<input type="file" name="file" />
<input type="submit" value="submit" name="submit"/>
</form>
<?php
$connection = mysql_connect("localhost","root","")
or die ("Couldn't connect to server");
$db = mysql_select_db("map", $connection)
or die ("Couldn't select database");
if(isset($_POST['submit']))
{
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file,"r");
if (($handle = fopen($file, "r")) !== FALSE) {
while ($fileop = fgetcsv($handle,1000,",","'"))
{
$a = $fileop[0];
$b = $fileop[1];
$c = $fileop[2];
$d = $fileop[3];
$e = $fileop[4];
$f = $fileop[5];
$sql = mysql_query("INSERT INTO hzy3o_zhgooglemaps_markers (title, addresstext, published, baloon, icontype, mapid)
values('$a', '$b', '$c', '$d', '$e', '$f')");
}
}
}

After successful insert make redirect to the same page:
header("Location: http://www.yourwebsite.com/yourpage"); /* Redirect browser */
exit();
Also make a check in database to prevent data duplication.
Your refactored code:
<?php
if (isset($_POST['submit'])) {
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file, "r");
if (($handle = fopen($file, "r")) !== false) {
while ($fileop = fgetcsv($handle, 1000, ",", "'")) {
list($a, $b, $c, $d, $e, $f) = $fileop;
$sql = mysql_query("
INSERT INTO hzy3o_zhgooglemaps_markers (title, addresstext, published, baloon, icontype, mapid)
values('$a', '$b', '$c', '$d', '$e', '$f')
");
}
}
}
?>
<?php if (isset($_POST) && count($_POST) > 0):?>
<form enctype="multipart/form-data" method="POST" action="" >
CSV<input type="file" name="file" />
<input type="submit" value="submit" name="submit"/>
</form>
<?php else: ?>
<?php
header("Location: http://www.shambani.org /index.php?option=com_zhgooglemap&view=zhgooglemap&id=1&mapzoom=13&placemarklistid=&explacemarklistid=&grouplistid=&categorylistid=¢erplacemarkid=¢erplacemarkaction=&externalmarkerlink=0&mapwidth=&mapheight=&Itemid=177");
exit();
?>
Try it.
