那句改为:
<a href="news.php?id=<?php echo $rows[content_id];?>" target="_blank">浏览</a>
另外,print_r($rows); 看看是什么结果。
<?php echo $rows['content_id'];?>
id=" 注意闭合
target="_blank">浏览
缺少 “
如果数据没取错的话,要这样:
<a href="news.php?id=<?php echo $rows[content_id];?>" target="_blank">浏览</a>
红色部分要在引号里,基础HTML知识。。。。
原来PHP格式里不能再加颜色标签,重来:
浏览
红色部分要在引号里,基础HTML知识。。。。
另外,像这种错误,你看浏览器的网页源文件就能知道为什么会这样了。
有时并不是没输出,而是你输出错地方了,浏览器解析后导致你看不到。
你缺少了一个 “
<?php echo $rows['content_id'];?>

那句改为:
