从两个类别获取Wordpress帖子

Question

我试图在一个页面上显示来自两个类别的帖子（6）

<div class="sponsoren_container_wrapper">
<?php $args = array ( 'posts_per_page' => -1, 'category' => 6 );
    $myposts = get_posts ( $args );
    foreach ($myposts as $post) : setup_postdata( $post ); ?>
    <div class="gallery_image_container">
        <a href="<?php
$content = get_the_content();
print $content;
?>" title="<?php the_title_attribute(); ?>">
            <div class="gallery_image_thumb">
                <?php the_post_thumbnail('thumbnail'); ?>
            </div>
            <div class="gallery_title">
                <h2>
                    <?php the_title(); ?>
                </h2>
            </div>
        </a>
    </div>
<?php endforeach; wp_reset_postdata(); ?>

</div> 

我将如何将类别ID“7”添加到该代码中，以使所有内容都像上面解释的那样工作？提前谢谢！

Answer 1

$args = array ( 'posts_per_page' => -1, 'category' => '6,7' );
$myposts = get_posts ( $args );

对我来说，“类别”不会通过，但“猫”通过了。我希望这能帮助到某人。

Answer 2

$args = array ( 'posts_per_page' => -1, 'category' => '6,7' );
$myposts = get_posts ( $args );

Answer 3

使用逗号分隔字符串：

$args = array ( 'posts_per_page' => -1, 'category' => '6,7' );
