How to show top categories only with Wordpress

Published on| December 4th, 2009 | No Comment.

Usually, WordPress home page, either permanently display the page, it is able to choose either a list of recent posts.(Bottom left of the screen management Fixed- [Options])
In this case, the list of latest posts in all categories will be displayed in the order they were posted.
That, in the order you wish to display only the categories that were submitted, and works as follows.

Or perhaps home.php theme, home.php does not exist, index.php, and I think that is to display the page.
Among them, should have the following loop.

<?php if (have_posts()) : while (have_posts()) :  the_post(); ?>

When you want to be displayed in the order they were posted only a certain category, this written before, only to be declared.

<?php query_posts('cat=4'); ?> 
 <?php if (have_posts()) : while (have_posts()) :  the_post(); ?>

In this example, the category ID = 4 is declared to be viewed only.

It is easy.()
This "query_posts" You can also set various other parameters.
If enough of these cases, tags and other templates can be easily made with the API, by using this, you need one line.
Quite so useful, and know how to use, it can be easy.()
