php web form

[GreatName]

 

I am very, very new to php and I though that I found this great one size fits all php script that will handle all my forms no matter what the field name is.

 

<?php
if ($_SERVER['REQUEST_METHOD']=="POST"){
if (strpos($_SERVER['HTTP_REFERER'], $_SERVER['HTTP_HOST'])>8 ¦¦
!strpos($_SERVER['HTTP_REFERER'], $_SERVER['HTTP_HOST']))
die("Bad referer");
$msg="Values submitted by the user:\n";
foreach($_POST as $key => $val){
if (is_array($val)){
$msg.="Item: $key\n";
foreach($val as $v){
$v = stripslashes($v);
$msg.=" $v\n";
}
} else {
$val = stripslashes($val);
$msg.="$key: $val\n";
}
}
$recipient="[email protected]";
$subject="Subject line of email";
error_reporting(0);
if (mail($recipient, $subject, $msg)){
echo "<h1>Thank you</h1><p>Response message</p>\n";
echo nl2br($input);
} else
echo "An error occurred and the message could not be sent.";
} else
echo "Bad request method";
?>

 

However, I am worried that my form may get hijacked and therefore I wanted to place some security.

 

So I found

 

function clean_input_4email($value, $check_all_patterns = true)
{
$patterns[0] = '/content-type:/';
$patterns[1] = '/to:/';
$patterns[2] = '/cc:/';
$patterns[3] = '/bcc:/';
if ($check_all_patterns)
{
$patterns[4] = '/\r/';
$patterns[5] = '/\n/';
$patterns[6] = '/%0a/';
$patterns[7] = '/%0d/';
}
}

 

however I cannot figure out how to call this function or even if this is the best solution.

 

If anybody can help me, I would be most thankfull.

The function you have found doesn't actually do anything.

thanks, what is the best method for me to protect my form fom being hijacked from spammers then? Assuming I wanted to use my one size fits all code.

[GreatName]

Just to clarify, Is there any way to protect this form from being hijacked by spammers and to still keep it in its one size fits all forms way?

record ip addresses of people using this form - have a time lapse on its use (1 post per min or similar).

 

the only way to is to record and control usage...
