<?php if ($_GET['category'] != $val['category_id'] AND $val['category_info']['title']) { ?> <a class="aw-question-tags" href="explore/category-<?php echo $val['category_info']['url_token']; ?>"><?php echo $val['category_info']['title']; ?></a> • <?php } ?>直接改成
<?php if ($_GET['topics'] != $val['topic_id'] AND $val['topic_title']) { ?> <a class="aw-question-tags"><?php echo $val['topic_title']; ?></a> • <?php } ?>但是没成功，请问如何实现？
