Post only

How to enforce that visitor is not using query string to access the page instead using post method only.
I don't want visitor should go thru GET method.

All variables from the query string are loaded into the $_GET array and all variables from the HTTP body in a POST request are loaded into $_POST. If you want to ensure that your users are using a post request, use the $_POST array.

PHP Code:

---

$var = $_POST['form_var_name']; 


---

This is a bit of code i wrote so if the users uses a GET request then it writes their IP to a text file!

PHP Code:

---

<?php 
$ipbanfile = "/home/site/public_html/Ipban.ban"; #IP Ban File

if($_SERVER['REQUEST_METHOD'] == "GET"){
$fp = fopen($ipbanfile, "a+");
fwrite ($fp, "{$_SERVER['REMOTE_ADDR']}");
fclose($fp);
die("So close... yet so far.");
}
?>

---

i see an error already...

PHP Code:

---

fwrite ($fp, "$_SERVER['REMOTE_ADDR']");

should be 

fwrite ($fp, "$_SERVER[REMOTE_ADDR]");
or
fwrite ($fp, $_SERVER['REMOTE_ADDR']); 


---

Code:

---

fwrite ($fp, "$_SERVER[REMOTE_ADDR]");

---

You shouldn't use that either, you have not included REMOTE_ADDR in quotes. This would be correct:

"{$_SERVER['REMOTE_ADDR']}"

Yeah, edited it, sorry i wrote that from memory. Simple mistake :p I also didn't need the extra die(); and exit(); so edited that as well. so...

PHP Code:

---

<?php 
$ipbanfile = "/home/site/public_html/Ipban.ban"; #IP Ban File 

if($_SERVER['REQUEST_METHOD'] == "GET"){ 
$fp = fopen($ipbanfile, "a+"); 
fwrite ($fp, "{$_SERVER['REMOTE_ADDR']}"); 
fclose($fp); 
die("Please do not use the GET method!"); 
} 
?>
