【问题描述】:
我有这样的情况,我想根据我选择的月份和年份从多行中获取数据库中的值(这个值使用逗号分隔),有关更多详细信息,请查看..
我的 Schedule.sql :
+---+------------+-------------------------------------+
|ID |Activ_date | Do_skill |
+---+------------+-------------------------------------+
| 1 | 2020-10-01 | Accountant,Medical,Photograph |
| 2 | 2020-11-01 | Medical,Photograph,Doctor,Freelancer|
| 3 | 2020-12-01 | EO,Teach,Scientist |
| 4 | 2021-01-01 | Engineering, Freelancer |
+---+------------+-------------------------------------+
我的技能 qmount.sql :
+----+------------+------------+-------+
|ID |Date_skill |Skill |Price |
+----+------------+------------+-------+
| 1 | 2020-10-02 | Accountant | $ 5 |
| 2 | 2020-10-03 | Medical | $ 7 |
| 3 | 2020-10-11 | Photograph | $ 5 |
| 4 | 2020-10-12 | Doctor | $ 9 |
| 5 | 2020-10-01 | Freelancer | $ 7 |
| 6 | 2020-10-04 | EO | $ 4 |
| 7 | 2020-10-05 | Teach | $ 4 |
| 8 | 2020-11-02 | Accountant | $ 5 |
| 9 | 2020-11-03 | Medical | $ 7 |
| 10 | 2020-11-11 | Photograph | $ 5 |
| 11 | 2020-11-12 | Doctor | $ 9 |
| 12 | 2020-11-01 | Freelancer | $ 7 |
+----+------------+------------+-------+
在我的网站中,我想用这两个表进行计算。因此,如果在我的网站上想查看从日期 2020-10-01 到 2020-11-01 之间的总金额,我会尝试使用以下代码显示:
输出示例
+----+-----------+-----------+---------+
|No |Date Start |Date End |T.Amount |
+----+-------- --+-----------+---------+
|1 |2020-10-01 |2020-11-01 |$ 45 | <= this amount came from $5+$7+$5+$7+$5+$9+$7
+----+-------- --+-----------+---------+
Note :
Date Start : Input->post("A")
Date End : Input->post("B")
T.Amount : Total Amount based input A and B (on date)
我试过这段代码来得到它:
<?php
$startd = $this->input->post('A');
$endd= $this->input->post('B');
$chck = $this->db->select('Do_skill')
->where('Activ_date >=',$startd)
->where('Activ_date <',$endd)
->get('Schedule')
->row('Do_skill');
$dcek = $this->Check_model->comma_separated_to_array($chck);
$t_amount = $this->db->select_sum('price')
->where('Date_skill >=',$startd)
->where('Date_skill <',$endd)
->where_in('Skill',$dcek)
->get('skillqmount')
->row('price');
echo $t_amount; ?>
Check_model:
public function comma_separated_to_array($chck, $separator = ',')
{
//Explode on comma
$vals = explode($separator, $chck);
$count = count($vals);
$val = array();
//Trim whitespace
for($i=0;$i<=$count-1;$i++) {
$val[] .= $vals[$i];
}
return $val;
}
我的问题是 $t_amount 的结果不是 45 美元,我认为上面的代码有一些遗漏,如果有任何建议,我非常感谢...谢谢...

您的问题解决了吗?
-
T.Amount = $5+$7+$5+$9+$7+$4+$4+$7 = 48. 在两个日期之间过滤。
