Wordpress Enable Adsense Shortcode

2009-04-29 08:37:33

Wordpress allows developers and theme creators to write functions that allow the user to use shortcode, i.e., [adsense]. This kind of "pseudo" code makes it easy for end users to insert elements where they would like without knowing about coding. Knowing that we can create shortcodes, we can create one to insert a Google Adsense ad anywhere in our theme.

function showads() {  
     	return '  
 
		 ';  
 }  
 
 add_shortcode('adsense', 'showads');

2009-02-27 01:51:22

The logic of this is that only browsers that understand "screen" understand "only", and of these, only the iphone has a "max-device-width" of 480px. The reason for the anti-IE comments is that some versions of IE render CSS regadless of media type declarations.
