从sidesbar.php的循环中排除当前帖子ID

目前，下面所有代码都显示了来自当前页面所在类别的3篇随机帖子。因此，如果当前页面属于“艺术家”类别，例如，请在页面的下面显示“艺术家”类别中的3篇随机帖子。我的问题是，当前帖子一直出现在这一部分中，我想将其排除在外，但无法使用我当前的循环来解决此问题。这是我的循环：

<?php if ( in_category( \'artists\' ) ) {  ?>
                <h2>Similar articles</h2>
                <?php // Display the 3 random posts from page category
                query_posts(\'showposts=3&cat=1,-12&orderby=rand\'); ?>

        <?php } ?>

        <?php if ( in_category( \'people\' ) ) {  ?>
                <h2>Similar articles</h2>
                <?php // Display the 3 random posts from page category
                query_posts(\'showposts=3&cat=3&orderby=rand\'); ?>

        <?php } ?>

        <?php if ( in_category( \'development\' ) ) {  ?>
                <h2>Similar articles</h2>
                <?php // Display the 3 random posts from page category
                query_posts(\'showposts=3&cat=5&orderby=rand\'); ?>

        <?php } ?>

        <?php if ( in_category( \'offsite\' ) ) {  ?>
                <h2>Similar articles</h2>
                <?php // Display the 3 random posts from page category
                query_posts(\'showposts=3&cat=7&orderby=rand\'); ?>

        <?php } ?>

        <?php if ( in_category( \'projects\' ) ) {  ?>

                <?php // Display the 3 random posts from page category

        <?php } ?>
