I want to create font size and background change buttons, which i know how to do it. The problem is with remember it, so if user will go to a different page, background and font will stay the same. How can i do it?
I was thinking about saving this in cookies. What do you think about that?
Is anyone can write an example of saving valible in cookies in wordpress.
Here is how you can sett a cookie whit a variable: Now it saves for one day.
$settings = $mybackground;
setcookie('background',$settings,time() + (86400)); // 86400 = 1 day
Print it in the body like an img whit this:
echo $_COOKIE['background'];
You can use this plugin for the font: http://wordpress.org/extend/plugins/font-resizer/
Description of the plugin:
This plugin allows you to give the visitors of your site the option to change the font size. The plugin acts over jQuery and saves the settings in a cookie. So the visitor see the same font size if they revisit your site. Which content is going resized, the resize steps and other options you can set on the admin page called "font-resizer".
It should be a start to get the background to changa also, just look how the font changes.
