How to create category page

Question

Anybody could help me to make a category page only. Thank you.

Answer 1

You'll want to stick something like this in your theme's category.php file:

<?php
// fetch the categories with the parent being the current cat
$sub_cats = get_terms('category', array(
    'parent' => get_queried_object_id()
));
if(!is_wp_error($sub_cats) && $sub_cats)
{
    foreach($sub_cats as $cat)
    {
        // Create your grid here, this is just an example
        printf(
            '<a href="%s">%s</a>',
            get_term_link($cat, $cat->taxonomy),
            $cat->name
        );
    }
}

This may be something you are looking for:

http://wordpress.org/support/topic/how-to-display-the-child-category-of-a-specific-parent-category

Which would be something along these lines:

$args = array( 'cat' => yourcatid, 'post_parent' => $post->ID, 'number_of_posts' => -1 );

$posts = get_posts($args);

foreach($posts as $post)
{
?>
    <a href="<?php echo get_permalink($post->ID); ?>">
    <?php echo $post->the_title; ?>
    </a>
    <p><?php echo $post->the_excerpt; ?></p>
<?php } ?>

This would go into the template you use for the the sub-category
