php - Checking if there is a cookie set, if not output script -


i try use php check if cookie set. if not want script output. if set don't want anything.

i not programmer , have no clue start this. have done lots of searches on google no avail.

cookie name = subscribed

the javascript source required output mysite.com/js/subscribe.js

thanks

if(isset($_cookie['subscribed'])) {     // if cookie there     $subscribe = false; } else {     // if cookie not there     $subscribe = true; }

you use basic isset check first, somewhere in top of file before output. in head, in html this:

<head>  <!-- standard head meta here --> <?php if($subscribe): ?> <script src="http://mysite.com/js/subscribe.js"></script> <?php endif; ?> </head>

you run inline, or use javascript check cookies. 1 example , handled in case else needed processed, unset, or else make sense of having cookies checked before output sent.

shorter version use in place of longer conditional above:

$subscribe = isset($_cookie['subscribe']) ? false : true;
