Wordpress Themes - WP Forum at BFA - [SOLVED] How to have random posts only on index page (not category, author...)?

At first, thanks for great theme :)

I'm working on an interesting online image-dictionary project (http://phut59.com), and I want to have random word on the index page. After a few searches I did it by adding a php code in function bfa_loop() in template_tags.php to query random posts.

Code:



function bfa_loop( $postformat = 'postformat' ) {



        query_posts($query_string . '&orderby=rand'); <!-- here is the code i added -->

        

        if( have_posts() ) : ?>

                

        <div class="post-list">

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

                <?php bfa_get_template_part( $postformat, get_post_format() ); ?>                

        <?php endwhile; ?>

        </div>

...

And it worked, I have random posts on the index page, but it does also to the category and author page too. After that, I figured out the category and author page use the same main template index.php. So I guess that to have normal posts in category (or author page) I must create a new main template "category.php" then make a another loop function like this in template_tags.php

Code:



function bfa_loop_norandom( $postformat = 'postformat' ) {

        

        if( have_posts() ) : ?>

                

        <div class="post-list">

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

                <?php bfa_get_template_part( $postformat, get_post_format() ); ?>                

        <?php endwhile; ?>

        </div>

...

Then call it in the category.php main template.

Code:

<!--<div id="container">-->

<?php get_header(); ?>

<div id="main" class="row">

        <div id="content" class="cf col8">



      

    <?php bfa_loop_norandom( 'postformat' );  ?>

                         

        </div>

        

        <div id="widgetarea-one" class="col4">

                <?php dynamic_sidebar( 'Widget Area ONE' ); ?>

        </div>



</div>

<?php get_footer(); ?>



<!--</div>-->

But it did not work, there was nothing on category page (for example http://phut59.com/category/tu-sieu-de/) . It seemed the new function I added not work.

I wonder if someone can help.

Thanks in advance :)
