在Wordpress中显示特定父类别的子类别下的所有帖子标题

Question

I have searched high and low for answers which is related to this code, however everytime i use this, it only shows the 5 recent post titles. What I wanted to do is show ALL post titles instead of the 5 recent post titles.

$categories =  get_categories('child_of=3');  
foreach  ($categories as $category) {
    //Display the sub category information using $category values like $category->cat_name
    echo '<h2>'.$category->name.'</h2>';
    echo '<ul>';

    foreach (get_posts('cat='.$category->term_id) as $post) {
        setup_postdata( $post );
        echo '<li><a href="'.get_permalink($post->ID).'">'.get_the_title().'</a></li>';   
    }  
    echo '</ul>';
}

In your get_posts call, try supplying the posts_per_page parameter.

So:

foreach (get_posts('cat='.$category->term_id.'&posts_per_page=-1') as $post) {

a value of -1 will return all posts in the category.

See the get_posts page of the Codex for more detail.
