Question

我想在链接中显示年份，月份以及博客帖子数量的存档列表。像这样：

2013
- 十二月（3）
2014
- 1月（4）
- 二月（2）

...等，它将链接到一个页面，在那里它将显示该月的所有帖子。

我试过了：

SELECT YEAR(date) as year, MONTH(date) as month, ....

并在php中完成：

<ul>
  <li><?php echo $year; ?>
      <ul>
         <li><?php echo $month; ?> (<?php echo $countpost; ?>)</li>
      </ul>
  </li>
</ul>

但我只是得到一个空白页面，我很确定我的查询错误。

编辑：添加数据库

postid | title | date | content | userid | active

Answer 1

试试这个：

SELECT YEAR(date) as year, MONTH(date) as month, COUNT(postid) as countpost
FROM postTable
GROUP BY YEAR(date), MONTH(date);

Answer 2

使用这些查询获得类似于您所描述的输出。

<?php
$con=mysqli_connect("localhost","root","","my_db");

$result=mysqli_query($con,"select distinct YEAR(date) as myyear from table");

while($fetch=mysqli_fetch_array($result))

{

echo "<b>".$fetch['myyear']."</b><br />";

$q1="select MONTH(date) as postmonth,count(*) as postcount from table where year(date)=".$fetch['myyear']." group by MONTH(date)";
$temp1=mysqli_query($con,$q1);
while($temp=mysqli_fetch_array($temp1))

echo "<b>".$temp['postmonth']."</b> (".$temp['postcount'].")<br />";

}

mysqli_close($con);
?>

希望它有所帮助。
