Get Cookies PHP

Question

Hi,

I'm setting a cookie on an anchor click on my page:

$("#btn_twitter_signin").click(function() {
    $.cookie("bookmarklet_twitter_signin", "true");
});

and on the server side i'm trying to retrieve it

$_COOKIE['bookmarklet_twitter_signin']

but strangely i'm getting an "Undefined index: bookmarklet_twitter_signin", though i made sure the cookie is saved correctly by checking from Firefox View Page Info, am i missing something?

Thanks.

It may have to do with the path, try:

$("#btn_twitter_signin").click(function() {
  $.cookie("bookmarklet_twitter_signin", "true", {path: '/'});
});

The PHP won't be able to retrieve the set cookie until a page reload. The PHP, since it's server side, only runs once when the page is loaded. So if you change a cookie after a page load, your PHP has already run.

This means you need a page reload for PHP to see cookies set by Javascript.

You'd have to use the AJAX architecture, which Jquery makes easy, to be able to do this without a page refresh.

Use var_dump($_COOKIE) (like Itay said) or print_r($_COOKIE) to print all the cookies with PHP. You'll be able to see what's going on.
