How to have homepage setup?

How can I have the homepage of my blow only show posts from a certain category?

 

I'm not sure, but you can take a look here

 

Just edit your index.php in your theme directory..

Find the following code there

<?php if (have_posts()) : ?>

Code (markup):

and immediately after that place the following

<?php
 
   if (is_home()) {
 
      query_posts('category_name=News');
 
   }
 
?> 

Code (markup):

This will show all posts from the Category News on the home page..

If you want to show posts from multiple categories on homepage use this code instead

<?php
 
   if (is_home()) {
 
      query_posts('cat=1,2');
 
   }
 
?>

Code (markup):

where 1 and 2 are the category ids of the categories to be displayed..

Now if you want to display all posts except posts from some particular categories use the following code instead

<?php
if (is_home()) {
 
      query_posts('cat=-1,-2');
 
   }
 
?>

Code (markup):

where 1 and 2 are the category ids of those categories which you don't want to appear on the home page...

Hope this helps..
