仅显示特定类别的帖子

Question

在我的page-home.php中，上面的部分会收到所有最新的帖子。

elseif($key == 'latest_post_block'){ ?>
    <?php if(of_get_option('latest_post_block_visibility') != '0'): ?>

                <?php endif; ?>

            </div>
        </div> <!-- blog-block-wrapper end -->
        <?php 
        endif; 
        wp_reset_postdata(); 
        endif; ?>
    </section> <!-- blog -->
    <?php endif; ?> 

但是，我只希望显示某类帖子，而不是所有帖子。这会发生吗？

是的，您可以像这样修改$args数组：

$args = array(
    'posts_per_page' => of_get_option('latest_post_count'),
    'cat' => 4 // Category ID
);

或者，按类别slug查询：

$args = array(
    'posts_per_page' => of_get_option('latest_post_count'),
    'category_name' => 'cat' // Category slug
);
