Setting a cookie with a $_GET function

Hey Everyone,

I want to set a cookie that expires in an hour that users URL vars to set it for example www.example.com/?a=whatever how can I get 'a' var from the URL and set it as a cookie and then on another page print the cookie?

Thanks!

 

You will need to get the value of the variable with $_GET['a']. After doing this you can simply use the php function setcookie() to set the cookie along with a name, value, and expiration. Here is the link to to documentation for that function: http://php.net/manual/en/function.setcookie.php.

 

As described above it's pretty simple :

To set the cookie:

if($_GET['a']){
 //then the URL var exists so set the cookie

 //The URL param values could contain malicious values so remove html entities before storing/printing the value
 $var = htmlentities($_GET['a']);

 //set the cookie with 1 hr expiration
 setcookie("cookee",$var,time()+3600);
}

//Print cookie value
echo $_COOKIE['cookee'];

PHP:

Is htmlentities good enough on its own for sanitizing the GET values? I'm not sure hopefully somebody could provide more info on this.

 

Thanks for the code, it all makes sense now!

 

Use POST rather than GET, it'll look tidier
