Making Cookies Work All Across A Website

[!!!!!]

Okay... I am trying to make a cookie that goes all across my website so it can keep displaying the information, but I only know how to make the cookie availabe on the page it was made at. I really don't want my website viewers having to keep using the info in Forms... So, can anybody please tell me how to make a cookie work all across my website? Thanks

www.php.net/setcookie

 

I would suggest reading that whole page thoroughly. Especially at the option domain and path parameters.

The cookie has to be set in the root directory to be able to be accessed by all pages.....I found this out a while ago as the cookie was being set in the current directory, which meant that when another directory was being accessed, the cookie didn't work. Try this....

 

<? 
setcookie ("cookie", "Hello", 0, "/");  
// The "/" sets the cookie to root directory
?>

//If you echo out $_COOKIE["cookie"], it will display "Hello".

I pasted that code into a Notepad, then made another one and put this in it:

<?php
echo $_COOKIE["cookie"];
?>

And the webpage is blank. Any answers to why??

Are you working with Localhost? If so look here: http://www.aeonity.com/frost/php-setcookie-localhost-apache

 

If not, try adding the domain parameter after the "/". IE:

 

<?php
// set cookie for one hour
setcookie ("cookie", "Hello", time()+3600, "/", 'yourdomain.com');  

 

Note there is a difference between www.yourdomain.com and yourdomain.com, use which ever you want but there is a difference.

Have a look in your browser preferences to see if the cookie is being set ot not
