我有一个查询，它从4种不同的自定义帖子类型中提取最新的帖子，这些类型都有一个与之关联的给定类别。我试图弄明白，如果最新的帖子有“探索”类别，即使它也有“户外娱乐”类别，我怎么能不显示出来。
<?php
$myquery[\'tax_query\'] = array(
\'relation\' => \'OR\',
array(
\'taxonomy\' => \'category\',
\'category__not_in\' => array(\'explore\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'category\',
\'terms\' => array(\'outdoor-recreation\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'take_category\',
\'terms\' => array(\'outdoor-recreation\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'story_category\',
\'terms\' => array(\'outdoor-recreation\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'news-category\',
\'terms\' => array(\'outdoor-recreation\'),
\'field\' => \'slug\',
),
);
$myquery[\'showposts\'] = 1;
query_posts($myquery);
while( $wp_query->have_posts() ) :
$wp_query->the_post();
?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php
if ( has_post_thumbnail()):
the_post_thumbnail( \'feed-fixed\' );
endif; ?></a>
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
<?php echo wp_trim_words( get_the_excerpt(), 20 ); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">>>More</a>
<?php endwhile;
wp_reset_query();
?>

检查数组是否包含未经实时测试但有效的PHP类别

// Not in array do something
