How to use widget multiple times

Posted by in Wordpress plugin on September 26th, 2009

In Wordpress 2.8, there’s a new widget API. The new widgets API is a class that abstracts away much of the complexity involved in writing a widget, especially multi-widgets.

Basically, you extend WP_Widget with your own class that provides a constructor and three methods — widget(), form(), and update().

  • widget() – outputs the actual content of the widget.
  • update() – processes options to be saved.
  • form() – outputs the options form.

* The WP_Widget source can be viewed here (read the phpdoc for moreinfo on usage): http://core.trac.wordpress.org/browser/trunk/wp-includes/widgets.php
* You can see examples of how to use it here: http://core.trac.wordpress.org/browser/trunk/wp-includes/default-widgets.php

Here’s an execelent example of the widget.

Does Google prefer Valid HTML & CSS

Posted by in Increase traffic on September 9th, 2009

I recently heard my friend saying that valid HTML & CSS is impotant. It can make your website rank higher in Google search. Is that true?? To prove this I browse a lot about this, and here’s the result:

  • From site-reference.com, saying that “Not only did Google rank both sites with obviously wrong HTML higher, they even refused to include one of the sites with valid HTML altogether“!
  • A discussion from webmasterworld. My summary, valid HTML does not help your ranking but probably will help you get indexed.
  • From streetdirectory. “How important is valid html if Google, Yahoo!, and MSN don’t even practice it themselves?”

So for me, if I have time, I will do the validation. It’s not too important for me.
