and PHP page
----------------------
<?php


if(count($_POST)) {

foreach(array('fmail1','fmail2','fmail3','email','name','txtcoments') as $key) $_POST[$key] = strip_tags($_POST[$key]);
if(!is_secure($_POST)) { die("Hackers begone");}

$emailto = "info@astrohope.com";
$esubject = "Astro Hope Page Recommendation";
$emailtext = "
$_POST[name] has used your recommendation form using an email address of $_POST

 

check this:
onSubmit="return checkfields()"

where checkfields() javascript function is declared?
what does it do? (i believe this is some kind of input validation)
is JavaScript enabled in your IE?

 

Why do you have if(count($_POST)) ?

You should be able to just use if($_POST)

 

is it complete code

 

Yes this is full code i try if($_POST) but Same result, i think problem is with
<? $refurl = $_SERVER['HTTP_REFERER']; ?> <? print $refurl;?> cord , i am looking other script = to this but no other cord give the result i want, any 1 know why this code did not work on IE, i am vary

 

The php code is not browser dependent so should work fine.

I would assume it is your javascript causing problems, in particular

<form name="tellafriend" action="tellafriend.php" method="post" onSubmit="return checkfields()">

and

<input onClick="validate();" type="button" value="Send">

 

Try putting <?php instead of just <?

In fact try this code here;

<?php
var_dump($_SERVER);
?>

and this as well

<?php
phpinfo();
?>
