I am trying to read a cookie which I’ve set with javascript, jQuery Cookie Plugin specifically, and then after that I’m reading it with PHP to write it into a database.
For some reason the cookie is being created on page load, but doesn’t “exist” until the page is refreshed. Which means that I’m pumping blank fields into my database tables.
The only way I can think of doing it is to AJAX out to a script which creates the cookie. Or ajax out to a script which returns the data to me in json.
The use case is that I’m creating a simple analytics class for an internal project, and I’d like to write into the database the users resolution, colour depth and all that jazz, which I’m using screen.width etc to get.
Cookie data are sent to the server (and forwarded to the PHP interpreter) when the client performs the request. Therefore, a cookie set by JavaScript on the client after the page has been requested from the server will not be transmitted until the next request to same server.
What you’ll have to do is to perform some kind of request (could be done via AJAX) where a PHP script handles the incoming cookie information and stores it in the DB.
