Question

这是模型（Excel.php）：

＆＃13;

function undangan($req_id)
    {
        
        $this->db->select("excel_id,request_id,to_name as nama,to_address as alamat_tujuan,to_zipcode as kode_pos, ifnull(tariff,0) as tarif ");
        $this->db->where('tariff = 0 and request_id =', $req_id);
        $query  =   $this->db->get('excel');
        return $query->result_array();
    }

＆＃13;

这是控制器（Admin.php）：

＆＃13;

function undangan()
    {	
    	$this->load->model('excel');
        $this->load->model('request');	
    	$data['results']   =   $this->request->request();       
        foreach ( $data['results'] as $key)
        {
            $tarif=0;
           	$req_id = $key['req'];
            $data['tarif'][$req_id] =   $this->excel->total_tarif($req_id); 
            $data['undg'][$req_id]   =   $this->excel->undangan($req_id);
           	foreach ($data['undg'][$req_id] as $value)
            {

                $tarif += $value['tarif']; 
                $this->db->where('request_id', $value['request_id']);
                $num_rows = $this->db->count_all_results('excel');
                var_dump($num_rows);
            }
           
            $tarif = $data['tarif'][$req_id];
        }
           
        $this->load->view('admin_view',$data);
          
    }

＆＃13;

视图（admin_view.php）：

＆＃13;

<div class="container">
<h3>Customer Request</h3>

<?php
    foreach ($results as $value) {
  
    ?>
    <div class="panel panel-primary">

            <tr class="primary" align="center">

＆＃13;

我想计算来自表格excel的行，其中＆＃39; request_id＆＃39; =东西.. 我在控制器中做了foreach里面的count_all_result，但它给了我：

＆＃13;

int(3) int(3) int(3) int(3) int(3) int(3) int(2) int(2) int(3) int(3) int(3) int(2) int(2)

＆＃13;

这不是实际的行总数。我应该在哪里count_all_result？帮帮我解决这个问题..谢谢

Answer 1

您可以在选择查询中使用at。

count

或使用

$this->db->select("COUNT(request_id) as total, excel_id,request_id,to_name as nama,to_address as alamat_tujuan,to_zipcode as kode_pos, ifnull(tariff,0) as tarif ");
$this->db->where('tariff = 0 and request_id =', $req_id);

Answer 2

试试这段代码：

daten  = read.csv(file="test.csv",head=TRUE,sep=",")
trash <- grep("Blank", daten[,3])
daten <- daten[-c(trash),]
iAv_temp <- grep("Intensity average" , daten[,2])
iAv <- daten[c(iAv_temp),]
iAv_name <- iAv[,3]
iAv <- iAv[,4]
iC_temp <- grep("Concentration average" , daten[,2])
iC <- daten[c(iC_temp),]
iC_name <-iC[,3]
iC <- iC[,4]
i=1
x=6
j=1
leng=length(iC)
leng_t=leng/6
iC_MW <- c(1:leng_t)

while (j<=leng_t)
{ 
  iC_name_short<-iC_name[i]  
  temp <- iC[i:x]
  iC_MW[j]<-median(temp)
  i<-i+6
  x<-x+6
  j<-j+1
}

使用codeigniter计算数据库中的行数
