Set default cookie

[jcalabro]

HI all,

I'm working with a stylesheet switcher which sets the value of the new theme name inside a cookie. Then I'm pulling that value in through the link's href.

Is there an easy way to set a default value without having it overwrite the new cookie value on refresh? Currently my default value continually overwrites the chosen theme on page load.

In my header:

<?php
setcookie("newtheme", "theme_a", time()+3600);
?>

<link rel="stylesheet" id="new-theme" type="text/css" href="/wp-content/themes/<? echo $_COOKIE["newtheme"]; ?>/css/style.css" />

if (empty($_COOKIE['newtheme'])) {
    // set a default
}

Thanks for your reply!

So i've set:

<?PHP 
	if (empty($_COOKIE['newtheme'])) { 
		setcookie("newtheme", "theme_a", time()+3600);
	} 
?>

When I select a new theme, "theme_b", the cookie sets for 10 days. Then I refresh the page and it returns to "theme_a" for some reason.

I'm using the jQuery cookie plugin to set the theme cookie on click.

$.cookie('newtheme', themename,  { path: '/', expires: 10 });

check your cookies to make sure your javascript code is working as expected.

I've set an alert after setting the new theme to display the cookie value. It seems to be setting correctly

opps - sorry it's working properly. I just had to clear my cookies.
Although, it does take 2 refreshes to set the default cookie. Any ideas why that why be?

php's $_COOKIE array contains the values that were sent to it by the browser. setcookie() does not manually update the array, it just tells the browser to send a cookie the next time it makes an http request. so, $_COOKIE won't be updated until the next http request.

You can use a seperate variable which you assign either the default value, or the value from $_COOKIE, depending on whether or not $_COOKIE has the value you want.
