因此,我通过 mysqli_query 获取值来动态生成报告。这是当前输出 - > http://i.imgur.com/87XWAxQ.png?1我想要的是,当我们为同一个项目回显任务时,项目列只显示一次项目标题并跨越数字该项目下的任务,即TIME MS应该只出现一次
编辑 - 表结构 -
日志(log_id,proj_id,task_id,user_id,小时,日期)
项目(proj_id,标题,描述)
任务(task_id,title,desc,user_id,proj_id)
$q="SELECT proj_id, task_id,SUM(hours),date
FROM log
WHERE user_id =$row[0] AND date >= '$s' AND date<= '$e'
GROUP BY proj_id, task_id";
$res=mysqli_query($con,$q) or die(mysqli_error($con));
while($row=mysqli_fetch_row($res)) /*while rows exist select each row to
extract and display project name task
name and sometime calc.
Problem - I wanna display just one cell
of project name till the tasks under that
project are displayed. I know this is
achieved by rowspan but using that here
is skewing up my table */
{
$q="SELECT `title` FROM `projects` WHERE proj_id=$row[0]";
$res=mysqli_query($con,$q) or die(mysqli_error($con));
$ptitle=mysqli_fetch_row($res);
$q= "SELECT title FROM tasks WHERE task_id =$row[1]";
$res=mysqli_query($con,$q) or die(mysqli_error($con));
$row=mysqli_fetch_row($res);
$time=round(($row[2]/$total[0])*100);
echo '
<td>'
.$ptitle[0]. //using rowspan here is skewing up the table as
// the loop executes seperately for each task
'</td>
<td>'
.$row2[0].
'</td>
<td>'
.$time.
'</td>
</tr>';
}
我知道某处有错误的逻辑,但我就是无法弄清楚。我需要以某种方式检查我们是否仍在显示同一项目的任务并计算编号。任务和集合
<td rowspan='.$count.'>Project Title</td>
